- power supply outputs
- Posted by Jay on January 19th, 2004
What V and mA should I expect to read from a healthy PS unit?
Using a multi-meter. Red lead to red cable, black lead to black cable
(yellow cable ignored).
Meter set to V(20) and the output is 5V
Meter set to mA(1.5V) and the output is 134.8
Normal?

Ummm... I would stop before you blow your power supply.

well now that I've taken the readings and stopped does anyone know if these
are expected results?

The current output is dependent on the load, as well as the voltage to
some extent. Voltages should be measured while the system is under
load. Use a monitor program like Mother Board Monitor 5:

Thanks, those are the readings I get... PC running.
I d/l MBM5 about 10 minutes ago! am about to install/run it.

Well now I have it running and it reports a mass of data.... unfortunately I
left my PhD at home!!
Any pointers?

Completely meaningless. To measure current you have to have the meter
in series. All you have done is measure how much current your meter
draws when connected to 5V.

What were you using as a load? And were you dumb enough to connect
the mA leads across the power supply (it goes in LINE with the power
supply)?
As to the current measure - that's only valid while it's running ...
since that's the variable in the power supply (the voltage is HOPEFULLY
fixed ... )
And, yes, I'd expect that from someone who didn't know what they
were doing.

My PC is freezing up all the time.
Non-Windows related (does it during POST too).
I've read here and other places tht a faulty power supply could be at fault
(apparently my CPU voltages are overly high too).
I'm trying to determine the PS output so that someone can tell me if it is
normal or stuffed.
(Among many other instructions) I downloaded MBM5 to read mobo temps.

Right.
Can anybody tell me the correct way to tell if a power supply is rooted
please?

Do you know how to test the output from a PS to determine it's state of
health?
I have a multi-meter here that tests V, mA and ohms. If this doesn't do the
job then I'll borrow a 2nd PS and see if my PC stops freezing.
And before yet another person tells me I don't know what I'm doing can I
re-confirm that I know this.
If I knew what I was doing then I wouldn't need to ask here.

One other thing you could do, it won't fix a goofy PS, is open your case
and run a regular house fan into it, past it. It may just be a heat
problem. And it may not be. <sigh>
Have you run the box on just one stick of Ram? That could be another straw
to grab. Intermitants are a PIA.
Mr. Ron Martel has a coupla lines one can add to <ahhhhh> either
Autoexec.bat or Config.sys, sheesh, I forget..... That will test memory on
bootup.
Maybe someone will chime in and give you a reference, I was at Ron's site
and can't find it.

Boot the system.
Set your meter to the appropriate voltage range.
Measure the voltage at the PS header/plug on the mobo by inserting the red probe into
the plug where the wires enter. Put the black meter lead in the ground hole.
Do not use the current (amps) setting.
Do not use the Ohms setting.
Inspect the motherboard capacitors. Look for any bulging on the tops.

If any bad ones found, toss mobo.

Yuo didn't read the instructions properly.
No bulging on the tops? Not even a little?
Go to bios setup. Mark down the hard drive settings. Set your bios to boot from the
floppy. Set "Reset Configuration Data" (or similar) to enabled.
Shut down. Disconnect your hard drive.
Boot with a startup disk.
Does it still lock up?
