Power Supplies advice ?

[Joseph]

I just built a new Asus A8V Deluxe, running a AMD 3500+, two SATA Hard,
and one Ultra ATA. Running the two SATA as STA IDE mode 7, (No Raid), Win XP
sp2.

Anyway I bought the power supply localy, and now they don't even carry them.
All the box says is it's a SP power supply. And I notice it puts out 11.612
Volts (+12) constantly, and the + 5 volt has spikes on it.
This is what I'm seeing with the Asus Probe program.

Thinking about getting a Antec True 480,.

Would I gain anything on the +12 being up there where it shold be, and could
that +5 constant ripple be bad news ?
I'm looking at it here, the +5 goes from 5.107 to 5.134 constantly.

If you are not having any problems, your power supply is doing fine. Probe
shows my voltage at 11.685 but when I check it with a real voltmeter it is
delivering 12.12 volts.
You can't trust some of the monitoring programs.

1. For reassurance: does your PC run properly?

OR

2. Does it crash frequently?

If the answer is YES to 1 then don't worry.
If the answer is YES to 2 then PANIC and buy anything that you think is
going to fix it, well not really: but if you haave lots of RAM you need to be
sure that you have a Power SUpply that puts out >300Watts.

It's the power that helps the PC do it's work, not the volts.

Yes, it runs good and it's pretty fast, so thanks for the Comfort. One of
these days I'll take the side of the Tower off and Use a Voltmeter on it.
Thanks again

I have the 64 bit AMD, so running two banks of 512K to give me 1 Gig on
normal.

That power supply sounds ok, and it puts out over 400 Watts, or I should say
suppose to.

Toms Hardware tested some and the one I mentioned is about what they
recomend, most of the others don't put out what they say.

Why bother qoting AMPS, the basic elctical conversion will tell you: Power (P
= V * I) or Watts = Volts X AMPS

Thus 300W = 12Volts x 25Amps!

Yeah, some power is taken up in the lower voltage side: however this is the
reason PSU makers quote Power Output and not another Primary measurement.
