Molex amperage?

post #1 of 14
Thread Starter 
I'd like to know the amperage of a molex connector, if you have the information for 12v, 7v, and 5v, that'd be awesome. I plan to hook up some IR LEDs up in a 5.25" bay to act in place of a Wii's IR emitter, so that I can more easily use my computer as a Wii emulator.

There's no 7v wire(or rail for that matter, check the ATX spec), only 5v, 12v and two grounds, the 5v and 12v wires are rated for 5A each.

Thanks. This bugs me a bit, though, as I'm pretty sure running that much through a dozen LEDs will burn them all (If rated at 50mAh apiece, which is rather high from what I've seen.)

Are you sure? o.o

I'll be honest, I have no idea how it works--but the 7v mod is apparently quite common. Or was, before people started buying fan controllers like hot cakes.

If you connect across the 5V and 12V (instead of 12V and ground or 5V and ground) you get 7V. 12V - 5V = 7V. I'm not sure how safe it is though, I've heard of people doing it but I don't know if your PSU is meant to handle it.

i dont think its that safe anymroe but im no pro on psu... i would say run them from a controller. jsut to test out what the leds can take?

11A per pin.

12v = 132w
5v = 55w
