Could I have a power supply problem?

nhvideoguy · 10-23-2008, 01:03 PM

I have a 4.5 year old custom built video editing system (build by a company that builds editing systems). For the last several months I have been having a series of “issues” (slowness, system won’t boot up in the AM, drives acting up, 1 USB port won’t work if something is plugged into the other – and other intermittent issues). I know it could be a lot of things, but I’m wondering if the power supply is failing on me? When I go into the BIOS and view the voltages this is what I get (when I first boot up).
The voltages in the BIOS seem low… these numbers change; I recorded the lowest I saw:
Lowest *** In BIOS Called
4.51 ***** +5
11.85 **** +12
-11.37 *** -12
4.12 ***** 5 VSB
1.42 ***** HW Monitor IN0 (CPU)
3.16 ***** HW Monitor IN1 (V Standby)
3.28 ***** HW Monitor IN2 (+3.3)

Are these numbers within limits or are they low enough to cause issues?
If they are an issue can they be brought up or do I need a new supply? I’m not planning on keeping the system a long time (maybe another 4 months) so if I could fix this without spending the cash, I would like to do that, but if a new supply is needed, it would be worth it – even if only 4 months.

The details:

Power Supply: Antec True 430
Antec AMG P160 Aluminum Tower
Mother board: Super P4SCT+II
BIOS: Phoenix Technologies, LTD 6.00 PG 02/20/2004
Windows XP Pro SP3
Intel 875P Chipset
Single P4: Pentium 4 3.2GHZ-800FSB - HT-512KB Cache
2 GB memory (4x512)
Video: XFX GeForce 7600GT 256MB
Adaptec SCSI card 39320
NewTek VT card (video I/O hardware)
Audigy2 ZS Sound Card
(added) Addonics (ADS3GX4R5-E) 4-Port External SATA II PCI/PCI-X Raid 5 Controller Card
PIONEER DVD-RW DVR-107D
System Drive: ST3250620A [Hard drive] (250.06 GB) – upgraded from a 160 GB
Spare Drive: ST3750640AS [Hard drive] (750.15 GB) – upgraded from a 250 GB
(unplugged power from): Two 73GB U320 10K RPM SCSI hard drives

Thanks in advance for any help you can provide!

on volts, it's a +-5% vaiance. However, a 430 watt PSU on a 7 series card is a no-no, even as low level as they are.

i know it is agp but i would be up here power wise

Thanks for the info magnethead... Is the 7 series card the video card? If so, that has been in there from the start - but maybe by adding the bigger drives and the SATA card - along with the PSU's age could have pushed it over the edge???
Also, the +/- 5% is good info, so by +5 should be no lower than 4.75 - so my seeing 4.51 no bad too right?
Bottom line, you think I should replace the PSU right?

Thanks for the product suggestion dai... But what is "agp" in this case? I could only find "Accelerated Graphics Port"...

Accelerated Graphics Port=agp
