Seasonic S12II-430 Undervoltage on Hard Drive 12V?

Hi,

I am currently supplying my computer with a Seasonic S12II-430 430W Power Supply.

It supplies power to the following components:

(24/7 power on, Very Low utilitization computer)

CPU: Intel e2160 CPU

RAM: 2x 2GB DDR2

Mainboard: P5E VM DO

Graphics: Integrated Intel

HardDrives:
2x 1TB SpinPoint F1 7200RPM
4x 1TB Western Digital GreenPower models: EADS and EACS
1x 500GB Western Digital SE16 7200RPM
1x USB 2.5 Harddrive

CDROM:
none

PCI Cards:
None

FANS:
4x 120MM 800RPM (Antec TriCool)
1x CPU Stock Fan

Problem:

According to Everest 5, the +12V line is sending only 10Vs, while other things such as +5 is 5.4V, 3.3V is 3.23V seem to be fine.

Is there a problem here?

Absolutely, it's certainly the next thing to do on my next restart.

however, in normal working conditions, would a 430W PSU be more than sufficient for this configuration?

Or better, you can check the 12 volt line at one of the molex connectors. Check between the yellow and black wires.
