Brand new Seasonic S12 330W, whacked out voltages

Based on MBM Dashboard, at idle:

3.3 = 3.25
5.0 = 4.08
12 = 11.19

Asus Sk8N with Athlon FX-51

What's the deal here? This numbers must be wrong yes?

Looks kinda iffy to me. I thought that they were only supposed to vary by a max of +/-5%.

As it happens, I've been noting down the voltages from my system, with 3 different PSU, 3 and 4 hdd's, and a GF6500 (low power) and X1900XTX (high power) video cards.

While I can't say the ramifications of your power levels, I can say the power levels I've used without any problems.

Vcore: 1.420 (always)
3.3V: 3.2 - 3.37
5V: (not measured with my software)
12V: 11.73 - 12.11
Vid: 1.7 (always)

I wouldn't worry about your 3.3V, but a your 5V is off by nearly 20%, and your 12V is lower than mine has every been.

Since CPU and video draw mainly from the 12V line I'd assume overclocking could affect it, but I doubt it would affect your weak 5V line.

Are you overclocking? Is the system running stable? Are the reading taken at idle?

Readings are at idle, without any overclocking or tweaking of any kind. I'm using MBM so I dont know how reliable that is. I'm not using a multimeter or anything.

I dont know about stability since I only installed the new PSU today. No problems yet...

Chances are MBM is reading the voltages wrong. Motherboard-based sensors are not a good way to measure voltages, only a multimeter will tell you what voltages your PSU is ACTUALLY putting out.

If you don't have a multimeter, the best way to judge is just stability. If you aren't getting crashes, you don't have a problem.

Great, I'll give it some time then...

Thanks guys!
