Too Much Juice???

[Dead_Again]

Hey, I just went out and purchased a COMPUSA brand, 400 Watt ATX Power Supply.

After inserting it into my new mobo (Asus P4B533E) w/ a P4, clocked at 2.26 ghz, and turning on the juice, I got 0 feedback from the screen. When I mean 0 feedback, I mean the screen was blank as if the computer was off.

I tried a 300 watt Power Supply I had laying around, and the system seemed to run fine. So when I reinserted the 400 Watt PSU back into the case, I finally got a screen w/ my bios. It said the CPU frequency was clocked irregularly or something to that effect. I haven't switched the jumpers. I haven't done anything at all. Except replace a PSU with one of a higher wattage?

Is that too much juice? Do I need to turn down the CPU frequency? As you can tell, I'm lost.

Right now, the computer is pretty unstable. Sometimes, I'll get something viewable on the monitor and other times, I won't get anything at all. Also, the computer will crash on occasion when I do get something on the monitor.

So does anybody know my problem? Any Ideas? I'm leaving for college in 2 days. And I can't figure out what my problem is.

Should I just get a standard 300 watt PSU?

Help me out here :(

Thank you.

your PSU will only supply "juice" to whatever components "ask" for. Your "juice machine" can never be too big, it can be broken and not dispense right, but never too big. It can be too small. I would tell everyone to line up i order of importance and only give the critical ones juice at first (i.e. video card and fans, leave floppy and HD disconnected, clear CMOS and restart.)

Another thing that's worked and I have no idea why is: take the juice away from the mother (take the power outa the motherboard) flip the juice dispesncer switcha couple of times (the power on button), give the juice back to the mother and have her get more juice (plug back into mobo and hit the power button)

good luck :)

You can never have too much power, just more power than you need. Seems to me if the 300W works and the 400W does not, there may be a problem with the 400W, your problem does not stem from the fact that you have "too much". I would swap the PSU for another, as it seems it may be defective.

No reason that it shouldnt be working for you, other than defective, try exchanging it, im positive you'll have results
