Hi,
I've had this PSU for almost 2 years now.
A few days ago the PC started having problems while booting up. All the fans would spin but the PC wouldn't POST or make any BIOS beeps to signify what the problem is. I had to switch off the PSU because the PC wouldn't turn off from the power button when that happened. Usually my next try to boot the PC would work. Sometimes, however, switching the PSU on after having switched it off would trip the circuit breaker of the room.
Now the PC doesn't boot at all. All the fans spin, apart from the GPU's one, and it doesn't POST or produce any BIOS beeps.
I've done several tests to rule out other hardware as faulty. Unplugging and removing everything from the motherboard apart from the CPU and the PSU itself, but it still doesn't POST or produce any BIOS beeps to signify that the RAM or the OS hard drive or the GPU is missing. Reseating the GPU and removing dust multiple times. Reseating both sticks of RAM in various configurations, either a single stick each time or both. I've also thoroughly checked the motherboard's capacitors for any bulging or leak. Also the pretty obvious removal of the CMOS battery and clearing the CMOS with the jumper. Nothing has produced any beeps or any different results.
Specs :
PSU : be quiet System Power B9 600W
CPU : AMD FX-8320
GPU : AMD Radeon HD 7750 2GB
Motherboard : ASRock 980DE/U3S3
RAM : Corsair Vengeance 2x4GB @ 1866MHz
