Connecting LEDs directly to the motherboard

[iZero]

Does this work? I purchased some pre-tailed LEDs from FrozenCPU, and they don't light up much at all when plugged into my EPoX. I have to cup my hand over them to see them dimmly lit up. The mutlimeter says 2.57 volts are coming out of the power LED pins on the MoBo.

Hmm, I'm no expert, but I think most LEDs run at ~5VDC, which would explain the dim light while you're feeding it ~3VDC. I have no idea why you're only getting 3 volts out of your motherboard though. You might be able to find some 3 volt LEDs that will do the trick for you.

I took a look at all of the LED's from frozenCPU, and they are all rated for 2.5-3 Volts.

Im assuming that you are using them as indicators LED's and not for trying to lightup the inside of the case.

They should work.

Try contacting FrozenCPU to ask why they wont lightup sufficiently. They may have a simple fix/answer.

Yes, I just got them to replace the stock green and amber lights for power and HDD activity. I e-mailed FrozenCPU and posted in their forums, but have received no response.
