Almost 2 weeks after getting a new motherboard and CPU which have left me in the red money wise, i still havnt got the bloody motherboard to work with a “Proper” decent power supply.

I had thought for some strange unknown reason that when i build my new PC and nothing powered up when i turned it on that the motherboard was dead and the CPU dead too. Then i wracked my brains and took everything out and finnaly tried out to see if it was the power supply which i paid a small fortune for back in march the “Corsair HX 620watt”. Anyway i put in an old “dodgy” Jeantech 420 watt PSU to see if was the power supply. By some unknown miracle the bloody thing decided to boot up.

And its been running for about 2 weeks now although its not as stable as the previous set up i had.

So today i went back to basics and took the whole fracking lot apart again and put in the PSU “Corsair Hx 620”. And nothing the PC wouldnt boot, took everything out the 4 ram DIMMs,graphics card discoonected fans etc. Tried the 4pin 12V slot on the motherboard, tried the 8 pin slot and nothing. The motherboard just wont power up with the 2 600watt powersupplies i have. For some unknown reason it will with the oldish 420 watt power supply i have.

Ive no idea what to do, to make matters worse i paid a lot for the motherboard and it doesnt list the CPU “AMD Phenom 9850 Black Editon” as a support CPU even though the mother board supports AM2+ CPU’s. Ive the latest BIOS installed and nothing.

I had the expensive Power Supply ready to return as an RMA but the after trying out the PSU on a old PC it works so ive no idea what to do now.
