bob16314See: How do I test my power supply? in the EVGA FAQs. Disconnect the PSU from everything..With ECO Mode disabled/off, the PSU fan should run continuously..If it doesn't, something is wrong with the PSU. Also: Which EVGA Modular Cables are compatible with my PSU?..All GQ power supplies are not cross-compatible with any other cables..So don't use cables from any other PSU with a GQ unit which could cause the PSU to turn off or ruin a component in your PC.
the_Scarlet_oneIf you plugged your HDD or SSD into the GQ with the P2 cables, your HDD or SSD is probably dead. The most incompatible cable is the sata cable, the pin outs are different.
