Compatibility and related parts
Before ordering, confirm that your case supports SFX power supplies; many PC cases built for ATX units need an SFX adapter bracket, which is not listed as included here. Check that 550W covers your CPU and the power needs of your chosen card from our graphics cards, or let the PC builder check compatibility for you. When bought as part of a PC build, assembly and testing are free. See other Thermalright products for matching cooling.
