Hello all, ran into a stressful problem while install my new powersupply. It's a Rosewill 650, after successfully installing it, i plugged everything back in, and once i hit the on switch on the PSU itself it instantly started up without me having to push the "Power" button, which was kind of weird. Everything started up fine, and even checked out a few games, and got on facebook, everything was working absolutely great, so i turned it off to put the side panel back on, then once i hooked it up all again, it did not boot up, nothing came on. No lights, no fans, no noises, nothing, but something that is driving me crazy is the moment i pushed the I button (To turn the PSU on) my computer instantly started up without me having to push the Power button. But after shutting it down, it wont power back up again. Hope someone can help out, thanks in advance!

So it power right on without pushing the power button. I had this problem once. Shut down the computer. Flip the switch on the back on the PSU to off. Disconnect the power supply from the wall replug it in to the wall flip the switch to on let it sit and let it build up the charge and press the button.

This kind of a weird procedure to do because it's reset the power supply to null or zero current. Once you flip the switch to on It should have to build current to power on.

see if that helps. Are you using the cord provided with your PSU?

Thanks for the reply, I followed your procedure, and still no go. The ethernet port light goes on for a second, and then shuts off. I have completely ran out of ideas myself.

Remove all connections internally, externally. Cable connections, RAM, CMOS battery, motherboard atx power connector. Press the power button for 10 to 20 seconds to flush out static charge. Reseat back then try again.

Thanks for the reply. I unplugged everything from the motherboard, and held the powerbutton for 30 seconds, hooked everything up, and still no go.

Then the PSU might be faulty as you would need to return it.
