9NPA+Ultra won't power up until it is unplugged

mrw · 06-27-2005, 08:21 PM

Here's an odd one. Just built a 9NPA+Ultra with an Athalon 64. System runs fine but when I shut it down (using Windows XP x64 Shutdown) the system will not power up again until I unplug the computer for approx. 10 seconds. I'm using a 300 watt 20 pin PSU. Any thoughts?

Make sure you have the power button on the case connected to the motherboard rite...thats the only thing i can think of

lol, that would be pretty funny, almost like not even having the comp plugged in

sounds like a dodgy power supply. try another if you can or put your current one in another PC... i had a similar problem with a crappy PSU once; the PC would just turn off and i would have to unplug it at the wall before i could restart it. if the PSU works ok on other systems i would reckon that you need a more powerful power supply

The power button is hooked up and working. Just can't power down and back up without removing the power. I'm wondering if it is the power supply as well. It was inexpensive, but well reviewed on newegg.com. The fit and finish were also very good.

what is the rating on the rails and what brand is it?

Not sure what you mean by rails. The PSU is this one:

It's 12V@15A. You're getting what you paid for. Seriously consider getting a new PSU.

mrw · 06-28-2005, 01:54 PM

Are you saying 12v @ 15amp is not enough? Sorry, but this is my first build so I'm not up on alot of this stuff. I know it was cheap PSU but the reviews overwhelming said it was the real deal. It even had SATA plugs which I understand is a bit unusual. Since price alone does not always indicate quality, what should have I looked for? The numbers indicated that the supply was 80% efficient which was higher than many "high end" PSU's. Seriously, I want to learn from the situation so I can choose better.

Would this be a good choice?
