Do these 3 things before closing this tab:
1Scan for outdated or missing drivers - takes under a minute2Repair Windows errors before they cause bigger problems3Fix the driver behind crashes, sound loss and screen glitchesTo check whether a graphics card will work in your PC, compare the exact GPU model with your computer’s motherboard, case, power supply, monitor, and operating-system requirements. A PCIe slot alone does not prove compatibility: the card also needs enough physical clearance, the right power connections, and any required firmware or driver support.
Find the exact model numbers for both the graphics card and your PC (or its motherboard) before checking. For a prebuilt computer, use the system maker’s specifications as well as the graphics-card maker’s requirements.

1. Confirm the motherboard has a suitable graphics slot
Look up the motherboard model in its manual or manufacturer specifications. Confirm that it has an available, full-size PCIe x16 slot intended for a graphics card. If the board has more than one long slot, follow the manual’s guidance on which one to use. Intel identifies PCIe x16 as the graphics-card slot in its PC-building guide; MSI advises comparing the motherboard and card PCIe specifications in its compatibility instructions.
PCIe generations are generally backward-compatible, but that does not guarantee every feature or model-specific requirement will work. Check the GPU maker’s requirements for the exact card. For example, Intel’s Arc B-series desktop guide calls for a full-size PCI Express 3.0-or-newer x16 slot and Resizable BAR enabled. Those are requirements for that documented family, not a universal checklist for every GPU. See the Intel Arc desktop quick-start guide.

2. Check that the card physically fits the case
Get the exact graphics-card board dimensions from its manufacturer, then compare them with usable space inside the case. Check all three dimensions and the surrounding layout:
- Length: Measure from the rear expansion-slot area toward the front of the case, accounting for drive cages, fans, radiators, and other obstructions.
- Width and thickness: Check the card’s width and slot thickness, often described by slot count, and confirm that it will not block neighboring cards or interfere with the case.
- Cable and airflow clearance: Allow room for the power cable to connect and bend without being pressed against a panel. Keep the card’s fans and ventilation clear.
Use the dimensions for the exact board you plan to buy. Partner cards can differ from a manufacturer’s reference design. NVIDIA’s GeForce comparison page lists dimensions and slot widths for its models. As one specific Founders Edition example, NVIDIA’s RTX 4080 setup guidance specifies clearance for a 304 × 137 mm, three-slot card and recommends an additional 36 mm (1.4 inches) for cable bend space. Do not assume those measurements apply to other cards or RTX 4080 partner boards.

3. Verify PSU capacity and GPU power cables
Check the graphics-card maker’s recommended system power for the exact model and compare it with the rating on your power supply’s label or in its specifications. Also confirm that the PSU has the exact PCIe GPU power connector or connectors the card requires, and that you can connect them using the manufacturer-approved method. CPU/EPS power connectors are not interchangeable with PCIe GPU connectors.
Wattage alone is not enough: a PSU can meet a stated power recommendation but lack the required connector, or its available cables may not support the intended connection. Requirements vary by model. Intel’s Arc B-series guide, for instance, specifies a 600 W minimum PSU rating and a PCIe 8-pin cable; that figure applies to the documented family, not to all graphics cards. NVIDIA’s model comparison lists power and connector requirements by card. Check the exact card and PSU documentation rather than applying one model’s figures to another.

4. Check monitor connections, operating system, and firmware
Compare the outputs on the graphics card with the inputs on your monitor. Confirm that your intended cable connects directly, or that any adapter is supported for the required display and resolution. The exact match depends on the monitor, card, cable, and adapter models.
Check the graphics-card maker’s supported operating systems and driver requirements. Also look for model-specific motherboard BIOS or firmware settings. Intel’s Arc guide documents family-specific operating-system and BIOS requirements; these should not be assumed to apply to other GPUs. If you are unsure, compare the exact models against their makers’ current support documents.

5. Take extra care with prebuilt and compact PCs
A prebuilt system may have a case, PSU, or firmware limitation that is not apparent from the motherboard’s PCIe slot. Find the exact PC model and check its maker’s upgrade specifications or support information, then compare those limits with the graphics-card board maker’s requirements. Compact cases deserve particular attention to card dimensions, slot thickness, power-cable clearance, and cooling space.
If you cannot confirm a clearance measurement, connector, or power requirement, do not assume the card will fit or operate correctly. Verify the PC and GPU model numbers and resolve the unknowns before buying or installing the card.

Quick compatibility checklist
- The motherboard has an available PCIe x16 graphics slot, and its manual identifies the correct slot to use.
- The exact card’s length, width, and slot thickness fit the case, with room for its cable and airflow.
- The PSU meets the card maker’s recommended system-power requirement and has the required PCIe GPU connectors.
- The card’s display outputs can connect to your monitor with a supported cable or adapter.
- The PC’s motherboard firmware, operating system, and drivers meet any requirements for that specific GPU.
- For a prebuilt PC, the system maker’s specifications do not impose a conflicting case, PSU, or firmware limit.
If you are comparing multiple cards
Check each exact board separately; cards with similar names can still differ in size and power connections. A useful comparison includes physical dimensions, slot thickness, power requirements, connector type and count, cable clearance, motherboard or BIOS requirements, supported operating systems, and display outputs. Assess performance, price, and value separately for the games or applications you intend to use; compatibility specifications alone do not establish how a card will perform in your system.
