Compatibility and related parts
Check that your graphics card needs no more than two 6+2-pin PCIe power connectors; you can compare options among our graphics cards. Your case must accept a standard ATX power supply with a length of 140 mm, and since this unit is non-modular, a case with some space behind the motherboard tray helps with cable management; see our PC cases. For a full system, the PC builder checks compatibility, and parts bought as part of a PC build get free assembly and testing. Cash on delivery is available across Lebanon.
