So the PSU (power suply unit) in my general use computer crapped out a couple weeks ago, which I promptly replaced with the PSU in my music comp because it isn't being used right now.

It seems unlikely because I haven't used that PSU that much, but it acting like it is going out too. If hit the power button, the computer won't turn on. I have to turn the switch off in the back for a couple seconds, then turn it on, and then hit power button up front and comes on.

My questions is, the PSU is one of the few things I've never researched much on, but am wondering: how do I know which wattage to get for my computer? I don't want to fry it.

Thanks again for the help.
 
you can probably find a way to figure out what you need.... the good thing is you dont have to... as long as you go large... the supply is rated as a capabilty... in otherwords it doesnt just put that out all the time... so as long as it's above what's typicly need you should be fine... if you've got dsp cards/multiple harddrives/providing usb power that sort of thing can add up... mine is 500 wts and seems to do real well...
 
I'm actually having the exact same problem with my DAW. even after upgrading from a 230 watt psu to a 400 watt psu... i dont know what the problem could be.

Let me know if you figure out what the proble is.

The PSU that was in my music computer was virtually brand new, I probably only powered up that computer maybe 20 times before I took it offline because I moved. And now its acting like it is crapping out already in the computer I put it in.

Guess I'll just get two 500w and see what happens. They are less that $20 on pricewatch.com.
 
If youre using $20 power supplies, thats your problem right there. Not all 500w power supplies are created equally. It is often the most overlooked piece in creating a home built computer. A power supply can easily lead to problems or stability on a daw.
 
I don't even know how much the one I put into my DAW that I moved into my general computer was. I noticed when I was putting it in it was much heavier than the stock ones, which could or couldn't mean anything. Since my current DAW and going to become my 2nd general use computer, I don't want to spend too much the PSU, maybe 30 or 40 each.

I'm going to build a rack mount w/ the dual quad cores I was talking to you about in a different thread and was going to put silent PSU, CPU, and case fans in it. Do those things work well?
 
Silent, as in an Antec Phantom, work well and usually are of pretty high quality. Of the hundreds of Phantoms Ive put in boxes, Ive only had one I can recall go bad.

I have had none go bad ;) great suggestion.
 
I would never skimp when it comes to the power supply, not all of them are created equal. Get a good name brand PSU, pay the extra bucks and then you won't have to worry about it.

Yes, it is possible that the problem could be something else, but a good PSU will give you many years of reliability, and can also be used in a future computer.

As far as music computers go, try not to pack too much unnecessary crap inside it that you don't need, just the basics. A five hundred watt PSU will be more than adequate to fit your needs.
 
my power supply came with my new case and therefore is probably a no-namer, and all-around bad psu that im gonna have to put up with till i can convice myself into pouring more money into the computer haha. I think i can get by with just turning the power on and off a couple times before it decides to boot.
 
my 500 wt is an antec cant remember the mod# but it's serious juice...
 
Any ideas on why this somewhat brand new PSU that I took out of my music comp to put into my general comp would be acting the way it is? I'm getting ready to head over to pricewatch to get a new PSU for my general PC, and taking the one out of it and putting it back into my music comp. That PSU was working fine in my music comp.
 
it's possible that something in the box is getting ready to roach... and drawing more current that it normally would... hence the supply is sagging..
