Using a “Power Supply Tester” to test an ATX computer PSU (and a voltmeter too)

I have actually been constructing computer systems for years and it appears like I have actually constantly obtained one maker in your house in some state of being “updated.” I encountered this little device on Amazon and assumed, “hi, that is easier than making use of a multimeter.”

Thanks!

It originated from China and it was right here in essentially a week. (The last couple of points I’ve received from China have actually been sent out lightning quick.).

We wish you take pleasure in. We will certainly be making even more video clips in the future, so please subscribe.

Anyhow, so the Power Supply Tester features essentially no directions. This ended up being a good idea. It creates a great children task to identify: (A) just how it must function, (B) whether it, as a matter of fact, functions like we assume it should, and (C) whether it is exact.

We beginning checking out up on the ATX Power Supply spec. There is a big quantity of fascinating info readily available pertaining to exactly how the ATX requirement transpired, that advertises the criterion, and so forth.

We make use of the Power Supply Tester to inspect the “great power” self examination result in miliseconds, and examination both the 24 pin motherboard port as well as a 6 pin, twelve volt lead. These outer ports are just evaluated utilizing red/green lights. We after that dig a little bit much deeper utilizing a multi-meter to check the 3.3 leads and take an appearance at the VSB (Voltage Stand By) performance.
