Possibly dying PSU?

[APE992]

I've got a 380w Antec that was working fine until the 9th when the nVidia Sentinel decided my MSI 6600gt wasn't getting enough power. My system experiences no issues aside from being warned and having the clock rate dropped "to a safe level". My mouse pointer jumps around a bit and a restart fixes both issues.

It was doing this sporatically for a week so I didn't give it much thought, mainly because it's been particularly cold lately and it might have decided a few negative values somewhere were bad.

Currently my voltages read:

Voltages: (Core 0: 1.664V, Core 1: 1.664V, +3.3: 3.248V, +5.00: 4.65V, +12.00: 11.309V, -12.00: -11.815V, -5.00: -4.958V)

The +5 went up by .1-.2 when I blew dust out of it. The +12 has been running at 11.3 for at least the last 3 months.

Currently I'm running:

2500+ Athlon XP Barton at stock speeds
2x512mb and 1x1gb Kingston
2x120gb Western Digital 8mb 7200rpm
MSI NX6600gt at stock speeds
1 DVD-ROM
1 DVD Burner
Asus A7n8x-x

As for USB I've got a USB headset, keyboard and mouse, all barely using a full 600ma or so.

Aside from the warnings and mouse jumping I haven't seen any problems. Removing one hdd didn't raise voltages any. Now it's been doing it daily, and the temps have dropped. Should I be concerned at all or is it due to the cold weather?

auxiliary power fitting Does your card have one of these receptacles, and if so, is the cable firmly plugged in?

Yes it does and it always was to my knowledge. I checked it earlier today to see if it was the issue, and it was firmly seated. It's even on its own line not connected to anything else. Not that it does a whole lot of good due to not being dual rail.

Hmm. If you happen to have a multimeter, you might do a reality check on the actual 12V wiring (yellow wires) to see what the PSU is putting out. Asus's reading can be well off-target.

Low temperatures actually make things easier on the power supply, so that shouldn't be the issue. Maybe your gut reaction is correct and the PSU is either failing or overstressed.
