重點摘要

A new graphics card deserves thirty unhurried minutes before it ever runs a game. This guide covers the full unboxing flow: checking seals and serial numbers, inspecting the card and connectors, testing detection, drivers, temperatures, fans, and output ports at first boot, and recording results so problems can be reported with proof.

Before You Open the Box

The unboxing check starts before the seal is broken. Choose a clean, well-lit table, keep the box, the inner packaging, and every insert, and have a phone ready to photograph anything that looks wrong. Photographs taken at the moment of discovery are far more useful than descriptions written later, and they cost nothing to take. Keep the proof of purchase with the box rather than filing it separately; if a problem appears, the box, the card, and the purchase record will be needed together, and hunting for one of them later wastes the very time that matters.

Do not rush this stage because the card is exciting. The purpose of an unboxing check is not to admire the product; it is to establish, while everything is still returnable and documented, that the item received is the item ordered, that it is complete, and that it works. Every step below serves one of those three questions, and skipping a step means answering that question on trust instead of evidence.

Seals, Labels, and Serial Numbers

Start with the outside of the box. Check that the seals are intact and consistent: a seal that has been cut and re-stuck, a box that has been re-taped, or a label placed over another label all deserve a photograph and a pause before opening. None of these signs automatically proves a problem, but each one is a reason to document the box thoroughly before proceeding, because the condition of the box is evidence that cannot be recreated after it is opened.

Then compare the identifiers. The model name, the memory size where printed, and the serial number on the box label should match the information on the purchase record, and the serial number on the box should match the serial number on the card itself once the card is out. The table below gives the comparison in full; every row should match before the card is installed.

If a serial number on the box and the serial number on the card disagree, stop. Photograph both labels, keep the card uninstalled, and contact the seller with the photographs. Installing a card whose identifiers do not match can complicate a return, because the seller may no longer be able to tell which item was supplied. The same applies to a model mismatch: a card that is not the ordered model should be reported before it is used, not after a week of gaming has made its history ambiguous.

A related caution: write the serial number down in a safe place, separately from the box. Boxes are thrown away, labels wear, and a serial number is the one identifier that connects the physical card to its warranty registration and to any later service request. A photograph of the label serves the same purpose, provided it is stored somewhere it will still be found months later.

What Should Be in the Box

Open the box carefully and lay out the contents. A typical new graphics card package contains the card itself in an anti-static bag or shell, a quick installation guide, and sometimes a power adapter cable, a support bracket, or a driver disc or download card. The exact contents vary by model and by seller, so the check is against the box's own listing and the seller's listing, not against a universal list. Count the items, and note anything missing before installation.

Keep every piece of packaging, including foam inserts, bags, and small accessories, until the card has passed its first-boot tests and the return window question is settled. Packaging is part of the product as far as a return is concerned, and a missing insert can turn a straightforward exchange into an argument. A single bag or drawer for the whole package keeps this simple.

Physical Inspection of the Card

With the card out of its bag, inspect it in good light before it goes near the computer. Hold it by the edges or the cooler shroud, not by the components, and work through the following points slowly.

First, the bracket and the cooler. The metal bracket at the rear should be straight and firmly attached, and the cooler shroud should sit evenly with no cracked plastic, no loose screws, and no rattling when the card is tilted gently. A bracket bent in shipping may still fit, but it should be photographed and reported, because a bent bracket can mean the card took an impact that may have affected more than the bracket.

Second, the gold fingers — the gold-coloured edge connector that plugs into the motherboard slot. The fingers should be clean, evenly coloured, and free of deep scratches, discolouration, or bent sections. Light handling marks can occur during manufacturing and testing, but heavy scoring, dark patches, or a finger that looks damaged are reasons to photograph and ask the seller before installing. Do not clean the fingers with abrasive materials or liquids; if they look dirty, a photograph and a question to the seller are safer than an improvised cleaning attempt.

Third, the output ports on the bracket. Look into each display port and HDMI port for bent pins, debris, or damaged surrounds. A damaged port may still accept a cable and even work intermittently, which makes it exactly the kind of fault that is better caught now, with the card still in its packaging, than discovered weeks later when a second monitor is connected.

Fourth, the power connectors on the top or rear edge of the card. Check that each connector housing is intact, that no pin is pushed back into the housing, and that the connector matches the power cables the system can provide. A mismatch between the card's power connectors and the available power supply cables is a stop-and-ask moment, not a moment to improvise an adapter, because an incorrect power connection can damage the card, the power supply, or both.

Fifth, the fans. Spin each fan gently by hand and watch it turn freely and stop smoothly, without grinding, wobbling, or catching on a cable or shroud edge. A fan that feels stiff or noisy by hand deserves a note and a test at first boot, where its behaviour under power can be observed directly.

Do not dismantle the cooler. Removing the cooler, the backplate, or any factory seal to look inside may affect how a warranty claim is assessed, and it is unnecessary for an unboxing check: everything that needs to be verified at this stage is visible from outside. If something inside the cooler looks or sounds wrong, that is a reason to contact the seller, not a reason to open the card.

First Boot, Step by Step

Install the card with the computer powered off and unplugged, seat it fully in the slot, secure the bracket screw, and connect the power cables firmly until each connector latch engages. Then work through the first-boot tests in order. Each test answers a different question, and the order matters: detection first, because nothing else is meaningful if the card is not recognised; drivers second, because an unrecognised card and a driver problem look alike; then temperatures, fans, and ports.

Step one, detection. Power on and enter the system information or device listing to confirm the card appears with the correct model name. If the card does not appear, power off, re-seat the card and the power cables, and try again. If it still does not appear, note exactly what was tried, and contact the seller rather than repeatedly reseating a card that may have a deeper fault. A card that appears with the wrong model name should also be reported, since it may indicate a labelling or supply error.

Step two, drivers. Install the driver from the card maker's or chip maker's official download, not from a disc that may be out of date, and restart when prompted. After installation, confirm the driver version and the card model in the system listing, and confirm that the display resolution and refresh rate can be set to the monitor's native values. A resolution that cannot be set, or a refresh rate that is missing, is a symptom to investigate now, while the card is still new, rather than a quirk to live with.

Step three, idle observation. With no game running, observe the card at the desktop for several minutes. Note the idle temperature reading, whether the fans are stopped or turning as expected for that model, and whether the display is stable with no flicker, artefacts, or dropouts. This idle baseline is the reference for everything that follows; without it, a later temperature reading cannot be judged as normal or abnormal.

Step four, load observation. Run an ordinary demanding application the card is meant for — a game at the settings it will normally use — and observe the same readings under load: the temperature reading, the fan behaviour, and the display stability. Watch for the fans speeding up smoothly as temperature rises, for the display remaining stable, and for any visual artefacts such as coloured blocks, lines, or flickering textures. Stop the test and note the readings if anything looks or sounds wrong; a test that is stopped early still produces useful evidence, while a test pushed through obvious artefacts produces only risk.

Step five, output ports. Test every display output that will be used, one at a time, with the monitor or television it will actually drive. A port that is never tested until months later is a port whose fault, if any, will be discovered long after the easy reporting window. Test the cable and the monitor too, by swapping in a known-good cable if a port behaves oddly, so that a cable fault is not mistaken for a card fault.

Step six, fan behaviour under change. Confirm that the fans respond to temperature rather than sitting at one speed regardless of load, and that they return to their idle state after the load is removed. A fan that stays at full speed after the card has cooled, or that never speeds up under load, should be investigated with the same care as any other fault, and the earlier guide on monitoring and overclocking software conflicts is worth reading before changing any fan setting, since a second tuning tool can produce exactly these symptoms.

Power Supply and Slot Checks Before First Boot

Two checks belong before the card is powered on at all, because both are easier to fix with the computer still open and unplugged. The first is the power supply: confirm that it provides the connectors the card needs, in the number the card needs, and that each cable is a proper power supply cable for that unit rather than an adapted cable from another purpose. A card with two power sockets needs both sockets filled; a card run on one socket because the second cable was missing is not being tested, it is being starved, and its behaviour under load will mislead every later conclusion. If the power supply cannot provide the required connectors, that is a question to resolve before first boot, not a problem to discover through instability.

The second is the slot itself. Confirm that the card is seated in the primary full-length slot the motherboard manual designates for a graphics card, that the slot's retention clip has engaged, and that no cable, drive cage, or case panel presses against the card or its fans once the side panel is closed. A card that works with the case open and fails with the case closed is usually a card whose fans are obstructed or whose seating shifts when the panel is fitted, and both causes are found by looking, not by replacing parts. Check also that the monitor cable is connected to the new card's outputs, not to the motherboard's outputs: a display connected to the motherboard may show a picture from integrated graphics while the new card sits idle, and the resulting confusion — a card that appears undetected while the screen works perfectly — is one of the most common first-boot false alarms.

Reading Temperature and Fan Behaviour Without Overreacting

Temperature readings at first boot are useful only as a comparison: idle against load, this card against its own maker's published specification for that model, and fan speed against temperature as the load rises and falls. A single reading, taken once, proves almost nothing, because it depends on the case, the room, the workload, and the moment. What matters is the pattern: temperatures that rise smoothly under load and fall again afterwards, fans that respond to that rise and return to idle afterwards, and a display that stays stable throughout. A pattern that breaks — temperatures that climb without the fans responding, fans that stay at full speed after the card has cooled, or a display that degrades as the card warms — is worth investigating, and the investigation should start with seating, power connections, case airflow, and conflicting tuning software before it moves to the card itself.

Do not judge a new card by a temperature number remembered from a different card. Different models, different coolers, and different power limits produce different readings under the same game, and a reading that would be alarming on one design is ordinary on another. The maker's specification for that exact model is the reference; a general article cannot supply it, and any number quoted without naming the model would be misleading. Record what was observed, under what workload, and compare it with the specification for the card in hand.

Recording Results and Registering the Warranty

Write the results down while they are fresh: the serial number, the date of first boot, the driver version installed, the idle and load temperature readings observed, the fan behaviour, and which ports were tested with which monitors. A short note, even a phone note with the readings, turns a vague memory of "it seemed fine" into evidence that can be quoted to a seller or a service centre months later. Photograph the installed card and the readings if convenient; a dated record is worth more than a confident recollection.

Then complete the warranty registration if the maker offers it, using the serial number recorded earlier, and keep the registration confirmation with the proof of purchase. Registration terms and periods vary by maker and by seller, so the registration page itself, not a general article, is the authority on what a particular card's coverage includes. Registering promptly also means that if a fault appears later, the claim starts from a complete file rather than from a search for a serial number on a box that may already be gone.

If Something Is Wrong

If any check fails — a mismatch, a missing accessory, a damaged connector, a card that is not detected, a port that does not work, artefacts under load — stop, keep everything, and report it. Keep the box and all packaging, keep the proof of purchase, keep the photographs, and keep the written record of what was tested and what happened. Do not dismantle the cooler, do not attempt a repair, and do not keep using a card that shows artefacts or fails detection in the hope that it will settle; continued use of a faulty card can blur the line between a supply fault and damage during use, and it can turn a clear report into a dispute.

Contact the seller first with the full set of evidence: the order details, the serial numbers, the photographs, and the test record. Describe what was checked and what failed, in the order it happened, rather than opening with a conclusion about the cause. A report that lets the seller follow the same steps will be resolved faster than one that only states that the card is broken. If the seller directs the card to a service centre, the same file — serial number, photographs, test record, proof of purchase — goes with it.

The Return Window: Principles, Not Guesses

Return and exchange terms are set by the seller and, where applicable, by the card maker, and they differ between sellers, between sales channels, and sometimes between product categories. No article can state a particular seller's window, and any number quoted without naming the seller would be a guess. The safe practice is to check the seller's terms at unboxing, on the day the card arrives, and to plan the checks in this guide to fit within whatever window those terms allow. If the terms are unclear, ask the seller in writing before the card is installed, and keep the reply with the purchase record.

Two habits protect the return position regardless of the terms. The first is speed: complete the unboxing and first-boot checks promptly after delivery, rather than leaving a sealed box for weeks, because a fault found promptly is a fault found within the window, and a fault found late may not be. The second is completeness: keep the packaging, the accessories, and the proof of purchase together until the checks are done and the registration is complete, because a return without its packaging is a weaker return under almost any terms.

Common Mistakes, Stated Plainly

Throwing away the box on the day of delivery is the most expensive common mistake, because it removes the packaging a return needs and the labels a warranty claim needs. Installing the card before checking the serial numbers is another: once the card is running, a mismatch is harder to prove and easier to dispute. Testing only one display port, then discovering a faulty second port months later, is a quiet version of the same error. Cleaning gold fingers with an abrasive cloth, improvising a power adapter for a connector that does not match, and opening the cooler to investigate a noise are all attempts to help that can instead create a new problem or affect a warranty assessment. Finally, skipping the written record — trusting that a fault will be remembered accurately months later — is the mistake that makes every other mistake harder to fix.

Frequently Asked Questions

The box seal looks re-taped. Should I refuse the delivery?

Photograph the box thoroughly before opening, including the seals and labels, and then proceed with the checks in this guide. A re-taped seal is a reason to document carefully, not an automatic verdict; the serial-number match and the first-boot tests are what establish whether the item itself is correct and working.

The serial number on the box and the card do not match. What should I do?

Stop before installing the card, photograph both labels, and contact the seller with the photographs. Do not install a card whose identifiers disagree, because installation can complicate a return.

How long should I keep the packaging?

Keep the box, inserts, accessories, and proof of purchase together until the first-boot checks are complete, the warranty registration is done, and the seller's return terms have been checked. After that, keeping them for the early life of the card remains good practice, since a fault may still appear.

Can I remove the cooler to check something inside?

No. Dismantling the cooler may affect how a warranty claim is assessed, and everything an unboxing check needs is visible from outside. If something inside seems wrong, report it to the seller with photographs and a description instead.

The card works, but one display port is untested because I only have one monitor. Does it matter?

Yes, if that port will ever be used. Test every port that will be used, with the display it will drive, as soon as a suitable display and cable are available, and record the result. A port fault discovered early is far easier to report than one discovered months later.

My card shows artefacts only under load. Is that a reason to report it?

Yes. Artefacts under load, after drivers are correctly installed and the card is properly seated and powered, are a genuine fault symptom. Stop the test, note the readings and the conditions, photograph the artefacts if possible, and report the full record to the seller.

What if the seller's return terms are unclear?

Ask the seller in writing before installing the card, and keep the reply with the proof of purchase. Do not rely on a general statement of return periods from any article, including this one, in place of the seller's own terms.

When to Seek Inspection

If a check fails and the seller's process points to inspection, or if a fault appears after the return window but the card is still within its warranty coverage, bring the card with its full file: the serial number, the photographs, the test record, the proof of purchase, and the warranty registration confirmation. An inspection that starts from that file can focus on the fault instead of reconstructing the card's history. Published inspection pricing for this service is listed in the HK$400–2,800 three-tier range on this site, and the workshop is at Room 1209, Dali Plaza, Shek Mun, Sha Tin. The contact number is 2186 8010, and WhatsApp is 6558 6806. There is no on-site service, so the card itself needs to come to the workshop.

A Final Checklist

Before the new card is considered fully accepted, confirm each point: the box seals and labels were examined and photographed where needed; the serial numbers on the box, the card, and the purchase record agree; the accessories are complete; the card, gold fingers, ports, power connectors, and fans were inspected; the card was detected correctly and the official driver installed; idle and load readings and fan behaviour were observed and written down; every port that will be used was tested; the warranty was registered; and the box, packaging, and proof of purchase are stored together. A card that passes this checklist has earned its place in the system, and its owner holds the evidence to prove it.
