Although the PSU itself may or may not be considered old hardware (new stock in 2015), the system it powers is.
The BIOS currently reports the following:
CPU Vcore: ~1.64V
3.3VSB: ~3.37V
+3.3V: ~3.15V
+5.0V: ~4.40V
+12V: ~12.28V
-12V: (-)~12.28V
+2.5V: ~2.54V
5VSB: ~4.73V
The specification of my Alpine 500W PSU:
+3.3V: 20A
+5.0V: 30A
+12V: 30A
-12V: 0.5A
5VSB: 2.0A
Should I be concerned by those numbers, particularly the +3.3V and +5V rails?
Now, I know that the Athlon XP CPUs consume considerably more power from the +3.3V and +5V rails than other CPUs of the time. Could this be why I am seeing such results? Knowing that I'm using an AthlonXP, should I still be concerned?
The PSU is purchased from new with very little to light usage to the present day. The system does not have many devices applied to it. Currently, it's running:
- 1 x 256MB PC2700 RAM
- 3dfx Voodoo3 3000 AGP
- Pioneer 105-S DVD-ROM
- PS/2 Microsoft Keyboard Pro
- Wireless 2.4GHz USB mouse
I'm using onboard sound and there are no interface cards installed. I can't see anything that would drag on the rails other than the CPU, although I'm no expert when it comes to PSUs. I thought 30A on the +5V rail was quite respectful for a modern PSU , but I do realise that PSUs of the lower brands (not Corsair, EVGA, Seasonic etc...) can waiver somewhat from their specifications.
