Power supply voltages

I have a 300w antec power supply, and I am just wondering what the voltages should be reading? I actually have quite a bit running off of it:

XP 2000+
Soyo k7v dragon plus!
geforce 3 ti
512 ddr 2100
8 cooling fans
Dvd rom, cd-r/rw
pci tv-in card
digital doc5
3 7200 rpm hard drives

Thats all of it. The voltages are reading (off of soyo's hardware monitor):
Vcore: 1.72
VCC2.5V: 2.44
3.3V: 3.27
+12V: 12.16
+5V: 4.87
5VSB: 4.89

I know thats a lot of info, I'm not even positive if it is accurate. Some of the voltages are self explanatory, others I am not sure what they pertain to. Do they appear to be within specs? Thank you so much for any help. I can't complain about my psu, I think its been great for only being rated at 300w.

Your voltages are like most people's... just a hair off Ideal, but still well within the tolerances of your various bits and pices.

The only one that's even close to marginal is the 5 volt readings... but that's only off by .13volts (about 3%)

Anything within 5% should be just fine, 10% is getting a little borderline.

The usual rough estimate is +/- 5%...
though ive had problems with poor PSU's when the 5V line gets below 4.8v

The voltage is fine.

Thanks for the reply, thats good to know. I really cannot believe how well this psu performs, but I guess thats what you get with a solid brand name.

I guess I am somewhat within specs then. You think that the psu could be holding me back when I overclock? The highest I can get is around 155fsb, I tried 166 and it wouldnt post...

i dont think so... is that mobo a KT266A or KT333? only the KT333 were able to do 166fsb reliably thanx to the 1/5 pci divider... otherwise the pci speed was way outof spec and cauzing problems with pci devices.

also it could well be your ram. you only have PC2100 thats certified for 133mhz. 155 is considerably beyond specifications. i wouldnt be suprised if its at its limits too.

It's a kt266A, I was hoping that if I could push it to 166 the pci and agp dividers would kick in, although I guess that wouldn't help with the ram.

Unfortunately that wont be possible as teh KT266A never had the 1/5 divider :frown:

So you are limited to whatever you can do FSB wise
