XSPC offers this handy tool for your ATX power supplies. Simply plug in your 24-Pin motherboard ATX lead from your power supply into this adapter and it will trick your power supply into thinking a motherboard is attached, perfect for power supply testing or for using your power supply outside of a case. Great for testing lights, fans, hard drives or the power supply itself when you don't have access to a motherboard, or simply don't need one. The tool will fit both 20 and 24pin ATX power supplies.
