VIDEO CARD COMPATIBILITY TIPS
When looking to purchase any video card, keep these compatibility points in mind:
- Motherboard compatibility - Every modern GPU fits into a PCIExpress 16x slot (circled in red here). PCIExpress is forward and backward compatible, meaning a PCIe1.0 graphics card from 15 years ago will still work in your PCIe4.0 PC today, and your RTX 2060 (PCIe 3.0) is compatible with your old PCIe2.0 motherboard. Generational changes increase total bandwidth (16x PCIe1.0 provides 4GBps throughput, 16x PCIe4.0 provides 32GBps throughput) however most modern GPUs aren’t bandwidth constrained and won’t see large improvements or losses moving between 16x PCIe3.0 and 16x PCIe4.0.[1][2]. If you have a single 16x PCIe3.0 or PCIe4.0 slot, your board is slot compatible with any available modern GPU.
- Size compatibility - To ensure your video card will fit in your case, it is good practice to compare the card’s length, width (usually # of slots) and height with your case's compatibility notes. Maximum GPU length is often listed in your case manual or on your case's product page (NZXT H510 for example). Remember to take into account front mounted fans and radiators which often reduce length clearance by 25mm to over 80mm. GPU height clearance is not usually explicitly listed, but can usually be compared to CPU tower height clearance. In especially slim cases, some tall GPUs may interfere with the side panel window. GPU width (or number of slots) compatibility is easy to visually assess. mITX cases typically support a max of 2 slots, mATX typically 4 slots, ATX focused cases typically 7 slots or more. Be mindful that especially wide GPUs may interfere with your ability to install other add in cards like WiFi or storage controllers.
- Power compatibility - GPU TDP, while actually referring to thermals, often serves as a good estimation of maximum power draw in regular use cases at stock settings. GPUs may draw their TDP + 20% (or more!) under heavy load depending on overclock, boosting characteristics, partner model limitations, or CPU limitations. Total system power is primarily your CPU+GPU power consumption. Situations where both the CPU and GPU are under max load are rare in gaming and most consumer workloads but may arise in simulation or heavy render workloads. See GamersNexus' system power draw comparison for popular CPU+GPU combinations between production heavy workloads here and gaming here. It is always good practice to plan for maximum power draw workloads or power draw spikes. Follow your GPU manufacturer's recommendations, take into account PCPartPicker's estimated power draw and always ask for recommendations here or in the Buildapc Discord. When necessary, it is strongly recommended you use two SEPARATE 8-pin power connectors instead of a daisy-chain connector.
