PSU Voltages

[jcb33]

Just installed Asus Pc Probe on my new pc... and it keeps giving me a warning, saying that the +3.3V Rail is at 4.08V...... Is this ok?

Also the Vcore keeps moving between 1.392V and 1.408V Is this ok? Its a 4800 X2 CPU.

Ug.... so what does it mean if its not acceptable ?

Im told its a HEC 480W..... i opted for a pre built system this time as it worked out cheaper than building it.... i just dont know everything inside it.... yet.... was told samsung ram and its OCZ so

It means that the stuff its powering isn't designed to take it over certain limits. Let me just check the official tolerances, but i think its 5%...

Edit: Yup, its 5%, so 3.47 max.
Never heard of HEC...

Ug.... so what problems is this gonna cause....

Thing is it could be the psu or the measurement. But seeing as its reading the 12v and 5v rails ok i suspect its the psu.
Difficult to say what problems it will cause as i'm not entirely certain what the 3.3v rail is for. I believe its for most of the motherboard logic such as chipset and ram, not sure about the cpu. Thankfully most of those components have their own mini regulators so they should be ok.

You need to try a different psu. I wouldn't run the system until you have a replacement psu of some sort. If its the same with another psu then ignore it.

Edit: Do you have a multimetre to hand?
If you have a sata power connector on it you may be able to measure the 3.3.

I have SATA Hard drives.... sadly i dont have a multimetre

Do you have a spare psu?

Somewhere yes... just a bit weary about messing inside with it being a ready made pc.... am told its an open case waretee mind, i just looked in my BIOS, all settings, temps, volts etc are the same as in the Asus Tool, however the +3.33V Rail reports as 3.328V... which looks decent to me.... and now im confuzed as to which one is correct

Also quick off topic question.... how do you find out what make graphics you have?..... (Manufacturer, Powercolor, Saphire etc) As it just says X1900 Family, not the model, or make
