I think my power supply died today.

Tim

I've had my desktop folding at 100% for about 2 weeks now. And I overclocked the 1.83 XP 2500+ to 2.2 Ghz a few days ago.

Today I was doing some things and had to restart the computer. Upon restart, the computer and monitor would come on for about 15 seconds, and it looked like a normal boot up sequence, but then the monitor light goes from green to orange, and the computer shuts down. With the power and hard drive lights ON. I tried restarting it a few times with the side cover off, and when the computer kicks off, the CPU fan stops in a couple seconds, but the chipset and case fans spin down slowly, taking about 20 seconds to stop turning. That's unusual for them. The motherboards' power LEDs stay on also. I have to use the power supply's own on/off switch to cut the power to the case and motherboard.

The current (get it? ) power supply is the Powmax 400 watt that came with this tower. I can try another power supply in a day or 2, then it looks like I'll be buying one this weekend coming up.

make SURE you get something other than a powmax. from what iv heard there the crap of the crap..get enermax or antec if your budget allows

I was recommended a PowMax by Thrax a year ago when I got my computer. I overclocked it a week after I got it, and its doing its job quite well. Running the same processor Tim is, a 9800Pro, 2 HD's, 4 case fans, 1 SFII, and a CDRW on an NF7-S v2.

Powmax works(worked?) rather well. They USED to have good price/performance, but something may have changed.

You say that everything starts to power up?
It may be that the cpu fan isn't coming to speed fast enought and being read as off.
Or it could be a thermal limit. Maybe you need to remount you hsf.
Or, you psu could be borked. Disconnect it, find out where to put the jumper, and power it up. Use a volt meter to check the outputs.

AND it is possible for Overheating components to pull more power in watts than non-Overheating components. OR fora DVD upgrade install to need a new PSU with higher wattage ratings than 400 Watts given what is in there. Your fans are 12 Volts, looks like 12 Volt rail is failing. That to me, says to get a 435-485 Watt PSU this time around. Antec makes a 485 Watt PSU that should be decent. 500 watts, if you plan to upgrade other things like a install a high-end video card and\or DVD burner during the use life cycle of the next PSU you buy, might not be overkill later, but for now it might be a tib much for immediate needs. I'd do the usual case cleaning also, and check the integrity of power harness and connectors in it also.

I'm going to buy a new Antec power supply unit today.

My computer has:

2 hard drives (Seagate Barracudas, 20 GB + 80 GB)
1 CD-RW / DVD drive
2 80mm case fans
1 CPU fan
1 fan in the power supply
NF7 V2.0
AMD Athlon XP 2500+ Barton unlocked @ 2.2 Ghz (10.5 X 200 FSB).

17 inch CRT monitor
2 harman / kardon speakers
PCI card for FireWire
ATI Powercolor Radeon 9200SE video card.

I owned a 350W from them
died shortly after buying it

I got my new Antec. It's an SL350. 350 watts. Cost $59.98 at Staples. I wanted to get the 430 watt unit, but it was $99.98, and they wouldn't accept the online price of $71.95 that I found and printed out for them. They said it had to be an actual store selling it. Well, the stores (Best Buy, Comp USA, Circuit City) all wanted $99.95-$99.99 for it.

So I hope this 350 does the job. Everyone seems to think Antec is a good brand, so we'll see.

It's quite a bit heavier than the Powmax 400 watt unit I took out.

I started up the computer and it runs fine. Except I'm getting a notice for a corrupt system information file. Hopefully it'll fix itself.
