After RMAing his EVGA power supply for coil whine issues, EVGA sent him a newly revised version of the same unit he bought featuring an upgraded pin layout. Unfortunately, EVGA forgot to send sgircys updated power supply cables to account for the changes. So when sgircys went to plug everything in, the power supply sent too much voltage to the wrong wires, frying all his storage devices.The story starts with Sgircy contacting EVGA regarding a coil whine issue with his shiny new EVGA GQ 1000W Gold power supply. After contacting EVGA, he sent the unit (at his own expense) to EVGA to get the problem resolved...
