Tricking a power supply?

[Rod Bishop]

Is there away to trick a power supply to check it's output with the power supply out of the computer?

I just restored a friends PC by installing a slightly higher wattage PSU. The old power unit must have dropped it's output some, because it was not strong enough to drive the board and it's options.

I have another PC that is so called dead without any signs of death also.

I pulled the PSU and I'm wondering how can I trick the unit to show the output.

It came from a HP Pavilion 700 and I don't have another PSU now to try.

Is there a way to turn on the psu with out the motherboard?

You can either buy a power supply tester or short 2 wires to get it to run and then use a voltmeter to test.

Unless there is a load on the power supply you wont get a true reading.

But with volt meter work really good than PSU tester. It is expensive.

To OP, never test with your volt meter for amp, it can damage.

Engrish?

A multimeter used to test voltage is useless if there is no load. As Strangle said. No point AT ALL testing a PSU at no-load as this tells you nothing.

Sorry wasn't meant to be rude mate. Just couldn't follow you. Still cant.

It's on order

I've ordered a PSU tester it will be here by July 20,

I'll repost after the first check of the system

I tested them all

My PS tester came in and I tested every Power Supply I pulled from dead PCs. and every PS was bad in one way or another. I like the PG test of a PS with the tester since it tell if the voltages are constant and not wavering.

Now I can test the power supply when I get in a bad PC.

I'm impressed it. I didn't want to open a PS without knowing it's true condition. I kept their circuit boards and fans, just in case I needed a part, and tossed the rest.

I've ordered more PS to get back to work.

Thanks for the help and tips.
