power supply crashes system on boot 5 different brands

April 21, 2012 at 22:18:01
Specs: vista/win 7, amd athlon 64 x2 5000+
My OEM 300 watt psu works perfect but with my new graphic card I need more power when I install this psu none of them work. Same issue crashes my system on boot. I used antec corsair and few more quality brands. When I plug my old power supply in computer starts fine.with the new psu nothing. Even the windows recovery CD crashes on boot. I removed all the accessories and just left the onboard video card motherboard and hard drive. Still no go. please someone anyone. I use the 24 pin and the p4 CPU pin. Everything matches my old psu plugs. This just makes no sense to me.

How are we supposed to offer any advice when you listed absolutely nothing about the power supplies, video card, motherboard, etc? Could it be you disturbed the CPU heatsink while messing around inside the case?

I'd assume the PSU's are not ones that are correct for your system. If the old one works and new ones don't there isn't much else to look at. This assumes all else remains the same.

Text, talk, drive...CRASH.

Hang up and drive @#$%^^

Check the capacitors on your motherboard, are they bulging, burst or leaking? Look at the tops and the bottoms of the caps, as they could pop from either side. I only say this because the issue that you have sounds like a power problem.

The good power supplies have less ripple effect than the older, cheaper one, so they have cleaner power. The old power supply maybe able to fluctuate a lot more than the newer ones, so they can power your board even with bad capacitors.

I'm sorry this is the first time i'm using this service. If I disturbed the CPU why does the old power supply still run my PC. And why exactly will my system stay on the bios page powered up for hours but as soon as windows try s to load it crashes. Is it possible not to have a compatible power supply. Like I said I have used 5 different brands from antec 600 watt to corsair gs600.. Me and a friend have been working on this for 4 days now no solution. I don't specify graphic card because I have removed everything and just left the motherboard and hard drive. I have a m2n68-la narra original amd 64 x2 5000+.

Oh and if the capacitors are damaged why does the old supply work like a charm?

If the old one works and the new ones do not then the new ones are wrong.

So if 5 major brands Are not compatible then my power supply is not upgradeable.

This is a odd problem, but I can tell you for sure that I have seen lots of these ASUS AMD HP motherboards fail. The nVidia chipset is junk, the caps are junk, and the transistors are junk. I do not think that the problem is with the power supply, it is with the board.

What if I buy a bigger case and do a dual psu boot my motherboard off the 300 and the gfx260 hard drive of the 600 watt. I would buy a dual psu adapter?
