Hey,
My dad got a new power supply for his build. Specs are:
EVGA Z87 FTW motherboard
i5-4670 processor
EVGA 970 graphics card
16GB DDR3 RAM
240GB Corsair SSD
500GB Samsung SSD
Random SATA optical drive
Old power supply: Thermaltake TR2 RX 750
New power supply: Seasonic Focus Plus SSR-750FX
Everything worked fine on the old build. The power supply fan was a little loud, so he opted for the new one.
New one installed - computer won't POST. Popped old one back in, works fine. Okay, I told him likely just a bad power supply. He did an RMA. Got the replacement, he just plugged in motherboard and CPU cables, and computer appears to POST. Pulled old one out, put replacement in, won't POST again. Old one back in again, works fine.
He's sent that one back again, and has a Corsair on the way instead.
Is there some stupid thing I'm missing? I've installed hundreds of power supplies and never had one act like this. I've thought about it on and off and can't seem to come up with any reason that 2 power supplies wouldn't work on hardware that is working fine otherwise.
