Hm. Now I can't decide between 500W and 600W. I've added a few things to that old system, including a massive hard drive, dvd rw w/ lightscribe and a USB 2.0 controller.

In any case, I want Active PFC, right? I have an Athlon XP cpu-- do I need two fans? If one's OK, these two look like nice choices at excellent prices:

COOLMAX CP-500T EPS12V 500W Power Supply - Retail
HIPRO TOP-600P5 ATX V2.01 600W Power Supply - OEM

Any thoughts? If I do need two fans, then that changes everything.

I'm feeling all kinds of: hard wary
What I hear: faaaaaannnnnnssssssss

I like the HIPRO 600w...it should be more than enough for what you need and quite stable.

It does look pretty nice... there's also this 500W continuous Cooler Max that's really quite lovely, too, for $20 more:

Any reason either of these wouldn't work with my aging mobo?

Thanks for all your help, btw. It was you who tipped me off that it was probably the PS in the first place (I'm so embarrassed-- it should have been one of the first things I thought of!).

You're welcome...

Either should work...and I cannot see any reason that they won't work on your motherboard.

Re: You're welcome...

Out of curiosity -- what do you think of this?

I've never heard of the manufacturer, and they don't exactly provide a whole lot of info. But I could pick one up tonight or tomorrow, which would be a Good Thing (as opposed to waiting 'til sometime next week for something from newegg).

Re: You're welcome...

No clue - never heard of them. Sorry.

what are we building a spaceship ?

what are you running in your case
500 is enough for 2 hard drives and 2 optical drives
with added sound card and video card

is this a gamming system or just a system to check mail and internet ?

Haha :) It's the machine I use for recreation AND work, so it's somewhere in between. Reliability is more important than performance (though I do have a tendency to do fifty things at once, so performance is important, too).

I ordered a 500W Enermax Liberty the other day-- I think it should do the trick :)

I know this is already late, but I remember from one of the tech docs a senior tech at work posted on our internal portal noted that power supplies are more efficient when 40-70% of their power is being consumed. It also had a fairly accurate listing of the wattage draw from components in a computer to help figure out what size power supply is best for a custom built system. It's kinda out of date now, though with the new processors, optical drives, and numerous monitors/TVs we have to choose from.
Just keep in mind 40-70% when making an upgrade to your system in the future.

Every wattage breakdown I've seen has been ballparky, but I think 500W should serve my needs quite well-- putting me right in the power consumption "sweet spot" you mentioned. :)

Today's graphics cards are the biggest things affecting power supply sizes now, particularly if you go SLi. Those and workstations operating outside of "rendering rooms" that have more than one processor (dual core or not) and multiple hard drives (read: 3 to 6) in the system are the reasons why 600 to 1000W power supplies are available for consumer purchase.

My next computer system, after I buy a car, will be one of those haunchers requiring Tim Allen-inspired power.
