I'm surprised your system even posts with those readouts. The ATX spec allows for 5% variance, so with the +5V rail at 4.49V you're well below the 4.75V low limit. Then there's your +12V rail at only +11.01V and the VIO at 3.1V. For your system, +5v & +3.3v Combined Load should be a minimum of 180 watts.
This is the most important spec since the capability of any PS on each rail measured independently isn't a true rating. My Antec PP412X 400W PS is rated at 245W +5v & +3.3v Combined Load and is currently running dual XP 2400+'s in a box with a RAID 0 array.
Only combined ratings matter since that's the way your system actually works. But you should go higher to allow for future upgrades. Antec's ratings are very conservative and even their cheapest 400W SL-series PS will be fine for you.
lol Dave. Sorry, I should have said about the readings being on the far right.
Justintime and DuronClocker, thanks.
Glad to know that im not gonna get woken up in the night by a loud BANG!!!! and find my new motherboard toasted
A friend of mine's power supply recently died so I thought I better check to see if mine was about to do the same, and with me just upgrading my graphics card and motherboard, I wasn't sure whether this would be putting a lot more load on this thing.
I might be adding another 40gb Seagate hard disk soon and set the drives as RAID0 (like you Dave), so I will have to see how things go.

A loud BANG! Thats exactly what my son heard when his whole system fried because of a chepo PS w/ 160w dc output, and no fuse protection. But all was ok for a long time until he added a burner and a Zip drive, + a mild OC on a T-Bird 1200. He must have reached its limit.
I have no idea what the readings were before she blew, he took off to college w/PC. But I rebuilt it for him. The PS that failed was an LGS non P-4, non 2.1 spec that came in the case, but it was a 300 watter. I guess adding more stuff to a system without first checking current readings is a gamble.
I bought a cheap but very good PS unit from Newegg for mine. Its a ENHANCE 300w P-4 2.1 spec and built like a tank! 200w DC output with all output line fuse (breaker) protected, and the auto fuse protection works! I accidently shorted 12v fan wires once, and it completely shut down, then auto resets in a minute or two. Very good unit for $28.00 Also check the ALLIED PS, its about the same.
