Compatibility and related parts
Before ordering, check that your graphics card is no longer than 322 mm and fits in 3 slots, and that your power supply is SFX or SFX-L from our power supplies. Air coolers must be 55 mm tall or less, otherwise choose a 240mm radiator from our CPU coolers, keeping radiator plus fans within 55mm total thickness. Storage is limited to 1x 2.5" SSD, so plan around M.2 drives on the motherboard. Our PC builder checks compatibility for you, and parts bought as part of a PC build get free assembly and testing.
