Default 20 Pin ATX Tester

Got a friend selling these pretty cheap, thought I'd pass it along.

BTW, Early on I had a PC die, power seemed OK, but the mother board was dead. Without a thought in the world about the power supply being the cause I replaced the board and it promptly died. My buddy, who sold me the board (new), told me a number of points where I must have screwed up and placing my faith in him I said I'd replace the board (again) but after saying the board may have been bad to start with. Taking this as an insult to his pride, he took the a new board off the self, tested it, installed it and it died. At that point he went looking for the cause and found that the power supply was pumping some odd over voltages on the 5 & 12 volt circuits. Apparently not enough to kill the fan or the HDs, just the mother board. He was some what embarrassed and as a way of joking about it bought both of us pocket sized voltage test meters (still have mine).

So in light of a number of recent post about power issues, I offer this.

There is like 1 to 100,000 chance you will ever benefit from such a device.

plua having an LED light up will tell you that you have voltage....but not
if the voltage is correct or within spec

My power supply testers are old, but still functional, motherboards plus
a POST card (I have spare POST cards, too) that signals whether or not
the 3.3v, 5v, and 12v circuits are within tolerance. If a power supply
blows up a motherboard (Hello, Bestec!), then the board goes to scrap,
and another one takes its place. I had to be sure I kept enough
motherboard-power-supply-testers around when I hauled off a bunch of
obsolete boards to the local electronic scrap dealer who used his Midas
touch to turn the boards into money for me.

And then we have the newer 24-pin ATX form factor power supplies with a
pair of 12v leads to the motherboard in a 4-pin connector... Ben Myers

All I can add...I had a PC shop owner test the one I suspected
(ruptured electolytic) and it tested good with all idiot lights on!
The bad PS would only light the green reserve power light on the m/b.
(so much for fast diagnostics)

That misinformation is typical of power supply testers. Three
conditions exist. Definitively good, definitively bad, and unknown.
A power supply tester can only identify a power supply as definitively
bad or unknown. For the same money, a tool that also has numerous
other purposes (multimeter) can determine all three states.

Meanwhile, any standard power supply must never damage a motherboard
or peripherals. And a motherboard must never damage a power supply.
Best way to test a power supply is with it connected to the computer.
IOW don't disconnect anything and get numbers from the multimeter.

It is not just a power supply. It is a power supply 'system'.
Unlike a tester, numbers from a multimeter can even identify in
minutes other problems such as failure of the power supply controller.

Testers are popular where one fears numbers. For a useful answer
(not using junk science reasoning), numbers are essential. A
multimeter provides numbers so that significant and useful information
can move the entire supply 'system' from unknown to either good or bad
- without doubts. A tester cannot do that. Same multimeter works for
20 pin ATX connectors, 24 pin connectors, future power supplies, and
so many other solutions such as household wiring, electrical
appliances, and automobile problems.
