Compatibility and related parts
Before buying, check that your case has room for a 150 mm long power supply, including space for the modular cables behind it; our PC cases list their PSU support. If you are pairing it with one of our graphics cards, make sure the card's power connectors are covered by the PSU's cables. The PC builder checks compatibility for you, and parts bought as part of a PC build get free assembly and testing. You can also see other Thermalright products.
