Test to see if my corsair ax850 is dead??? Help please!

post #1 of 17
Thread Starter 
Just got all my parts in today. First thing I did was check the power supply. It is modular so I hooked up a single fan to the power supply and it would not turn on. Yes of course I have tried plugging the power supply into numerous sockets throughout the house and it won't power not even a single fan.

I then hooked up the power supply to the motherboard and it will not turn on.

Is my power supply DOA????

Is there another way for me to check if my power supply arrived dead or alive?

Help me. ;(. Corsair is closed for the day, already tried calling.

Did you short the green wire and a black wire on the ATX connector? This may be an obvious yes but since you didn't say that you did that... I have to ask

No I did not. I did not see anything about that in the directions. How do I do that?

It's not a normal step that people take, but it's an easy way to see if your PSU will turn on.

It's the green wire and black wire on the 24 pin connector. Any black wire will do.

That's absolutely necessary when testing a PSU.

Basically it's what the power button on your case does. The power button shorts two pins of your motherboard that are connected to the PS_ON (green) wire of your PSU's ATX connector and one of the GND (black) wires. Doing that tells the PSU "hey, time to turn on".

So if you don't have the PSU connected to a motherboard, and the motherboard connected to the case, you need to short those two pins on the ATX connector yourself.

So here's how to do it simply.
Take a paperclip you're willing to sacrifice. You're going to have to unwind it. Plug a fan into your PSU, connect it to the wall outlet, flip the switch on. Then identify the pin connected to the green wire on your 24-pin connector. Insert the paperclip in that hole, and the other end of the paperclip in any of the pins connected to a black wire. The PSU should turn on, as should your fan.

Connecting it to the motherboard does nothing if you don't short the PS_ON pins on the motherboard.

Damn it, I do not see a green wire cause all of the wires on the ax850 are black. Was going to try what you linked me but yeah,,,,.

That blows! You're right the AX850 wires are all black.

If someone could count the pins from the end, that would help. Of course he would have to trust you to not explode his brand new psu!
