Compatibility and related parts
Before you buy, check that your case accepts a standard ATX power supply with a 150 mm length, and leave space for the fixed cables, since they can't be removed. Look at the power needs of your processor and your graphics cards to make sure 850 W gives enough headroom. Browse PC cases for a good match, or use our PC builder, which checks compatibility for you. Parts bought as part of a PC build get free assembly and testing.
