Are my voltage sensors not correct or is my PSU too weak

[Gomce]

I have the following system

Tbird 1.4
Gbyte 7vtxe mobo
256mb ddr ram
gf3
sblive
dvb satellite cart (technisat skystar1)
ethernet card
hdd maxtor 7200 rpm
cdrw liteon 12x
dvd hitachi
modem pci 56k

The voltage sensors shows the following readouts

core: 1.74V
+3.3V = 3.26V
+5V = 4.70V
+12V = 11.61V

-5V = -1.39V (?)
-12V = -6.52V (?)

The PSU is generic 250W 🙁 because where I live I cant order or purchase brand name psu.
I don't experience problems, but I did get blue screens and I couldn't have start these new Creatures benchmark program posted on the forums.

help, advice?

Your +5V rail is a little low and I might worry about that. A weak PSU is a possible cause of BSOD's. And, a 250W PS on with a Athlon 1.4 is not recommended by AMD as per the "recommended power supply list". Briefly scrolling though the list I could only find one 250W PS that was recommended for a 1.4 Athlon (an AOpen model).

I would seriously consider looking at purchasing a new PS if I were you. At least a 300W supply, preferably a quality 350W supply.

A 1.4ghz T-bird needs a lot of juice. A 7200rpm drive and a GF3 also doesn'thelp and is probably pushing your PSU to the limit. A quality 300w PSU is the minimum in order to run your setup reliably. A 350w Enermax or a one of the new 330w True Power Antecs should be the minimum.

I think the harddrive and the other ide devices run on the 12v rail....which is also a bit low...


Are those idle voltages as read in bios, or read during loading of the cpu in some intensive activity??? Loading will result in possibly a larger drop as the power supply is already dropping the rails....

4.6v on the 5 v rail is almost 10 percent down and that is definitely an issue...
