How to short an AT powersupply?

[swimscubasteve]

Do I short some pins on the MB connector or something like that? Google has been no help.

Yes, The green and black IIRC

Should I use an insulated wire? Am I going to fry my ass if i use a paperclip?

Can anyone confirm the green/black suggestion (just want to make sure I'm not going to catch the place on fire)?

EDIT: wait, you mean ATX and not AT, right (just to make sure)

Oh, and yeah, if I were doing it, I'd use a decent gauged insulated wire

AT as in the really old kind that nobody uses that has a button on it that will turn it on without shorting anything out?

EDIT: AT psu

For AT PSU's, it isn't started by the motherboard -> Power switch as in an ATX computer.
There's generally a seperate switch.

Green and black, makes it crack 😉

That's what I had going for a while too before I got a new PSU.

I think you just gave me a great idea... 🙂

So would that switch be attached to the PS?

Yeah, but unless you got this PSU out of a very old computer, it's an ATX one.

I'd be very suprised if this was really an AT psu.

There's a picture in the switch in the newegg pics. It's the box at the end of a cord with a spring around a long button sort of thing.

EDIT: if your PSU has a connector like this, it's an ATX one.

EDIT#2: AT power switch (it will be on the end of a cord coming from the PSU if it's an AT unit.

I bought the PS because I needed to put a fan inside my old ass big screen tv. The guy I bought it from said it was AT but apparently it's not.

Thanks to all for your great help!

Be careful inside your TV!!!! Those things can really hurt you.

The general nature of power supply circuitry is similar to battery charger circuitry. Almost all battery chargers can be damaged by powering them up without some type of "load" for them to work with. Higher quality computer psu's should be adequately protected from that sort of problem, but it's really easy to set up a load when you have several fans to listen to and to compare volumetric output on.

I just did that recently with several hsf's and while I was at it, compare psu noise as well. To provide the "load", I just used a spare hard drive.
