I have tried to upgrade my computer, but I have strange problem.

My PC won't power up with my 430w Corsair or 450W Cooler Master, but it does power up with my very old 210w PSU.

Motherboard: Asus M5A78L LE
CPU: AMD FX-4100
PSU(s): Corsair CX430W V2 ---- Cooler Master GX 450 W --- Old 210w

So this is my minium setup I try to startup without anything extra, but it just starts with my old 210w psu.

I have tried to take motherboard out to cardbox and start up on top of it, but no luck. Tried to reset bios (jumpers and removing battery), but I'm out of ideas.

Both psu's works on my other systems.
