· EVGA power supply allegedly kills 22TB of customer storage

EVGA power supply allegedly kills 22TB of customer storage — revised model from RMA had a different pin layout and killed all SATA-powered devicesThe vendor changed the SATA pin layout on the EVGA GQ 1000W, which isn't compatible with previous power cables.Reddit user u/sgircys on the DataHoarder subreddit reports that EVGA accidentally destroyed 22TB of storage in his work PC. 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...
