Momentary power and reset switch - Page 2

post #11 of 15
Is there anyway you could borrow a multimeter? Then you can see if the diode (of the LED) is working.

I bet the mobo is outputting 5v or maybe less for the power on light. The switch probably has a resistor in it for 12v hookup. I'd just hook it up to a molex which will be on when the system is on.

For the HDD LED, you'll probably have to wire it through a transistor to 12v power.

I will see if I can borrow one and test if its functional. I will also try the molex/transistor route although unfamiliar with it I will do some research thanks for the help again!

Could this be a PSU issue though as I continually get reports that my GPU is underpowered but I am on a 1200W PSU with not that much on it.

A transistor has three legs. You give it a ground, one leg is switching power (your 5v in from HDD LED connector), the other leg is higher voltage to be switched (12v). This operates like a relay, but instead of a coil operating a set of points, this does it electronically. You can find the pinouts on Google easily, or just Google for how to wire a transistor. It's super simple.

What is reporting your GPU being under powered? Di you have the 4 or 6 pin connector hooked up to power as well? You might want to check that auxilliary power input connector out to make sure it's got the right power levels coming in on it.

If you're going to be doing case modding, I'd highly recommend investing in a halfway decent multi-meter. They're worth every penny if you've got to chase down any electrical issues. The LCD ones are ok. Mine's analog (big needle). Analog ones are really the best for tracking down intermittent stuff, like wire breaks and shorts as the response time is super low. A tiny hint of a connection, and the needle will twitch. The LCD one, you won't see that.

Will check it out and thanks.

Its a free antivirus system analyzer by webroot in addition to seeing roughly 300mhz clocks via system analyzer with both a 8 pin and 6 pin connected directly to the PSU
