Hi Everyone,
i'm building my own PC for the very first time, however I am an Electrical Engineer so I do have some knowledge about some things. I am using the PPCS500 power supply, and the Gigabyte GA-EP45-DS3L motherboard. I turn the system on and the power supply doesnt seem to boot and nothing else seems to turn on. The switch on the front case is activating when pressed (checked with multimeter) and appears to be going to right place.
I disconnected power to all peripherals except motherboard where its connected to the ATX connector (2x12) and 4 pins on the 8 pins of the power connector (according to the manual from the power supply).
One 'Aha!' that I noticed is that the power supply does NOT have a -5V rail, but it looks like the motherboard expects it. Could that be why my system is not turning on?
I guess i"m a little confused because I chose teh same components as the "Toms Hardware $625 gaming build" from recently and somehow they got it to work. Oversight on their part? Any other ideas?
