PC Specs just before I begin -
Motherboard: ASUS M5a97 (original, non 2.0 / LE 2.0)
Graphics Card: Sapphire-AMD Radeon HD 6870
CPU: AMD Phenom II X4 980
PSU: Corsair CX430 (quit) / Apevia Turbolink ATX-CW500WP4 500W (new)
Just recently I had my power supply of roughly 4 1/2 years quit on me when I accidentally disconnected a haphazard extension cord setup and had my computer cycle on / off. I'd noticed the Power LED on the motherboard was blinking when I came back to my PC, and when I'd attempt to power my computer on, nothing would happen. I instinctively thought that it was a fault of the power supply, so I breadboarded for quite a while until I came to the conclusion. During my breadboarding, I'd disconnected pretty much everything from the motherboard. It wasn't until then that I managed to get a 500w power supply from a friend of mine 7 days later, and reconnected what was strewn all over the place.
I screwed the power supply into the computer chassis and connected all of the sockets; each and every chassis fan was connected, the CPU fan included, I had the SATA power cables on the PSU going to the CDROM and my 2 HDDs, all front panel LEDs were connected -- the whole nine yards. To my excitement, my computer started up again. Everything spun up, lit up, I could hear my hard drives spinning as if they were under load (like usual), my GPU fan was running, everything seemed to work; but I had no picture onscreen. Along with that eccentricity was the absence of a POST beep, which I'd chalked up to be my own failure in wiring the speaker to the front panel, but I attempted it as instructed on the manual and still didn't hear any POST.
The PSU in question seems to be a tad bit outdated, but I'm not entirely certain -- it only has one 4-pin PCI-E connector. My motherboard has one 8-pin PCI-E socket, and my graphics card requires two 6-pin connectors. If I try to connect a molex adapter to a normal 4-pin peripheral power cable and insert it into the 8-pin socket on the motherboard, my computer refuses to turn on until I remove it from power, remove the molex, then press the power switch.
Things I've tried
- Removing the graphics card from the motherboard and switching it out with an older (but functional) GPU that only requires the PCI-E slot on the motherboard to work (to no avail)
- Fitting the 4-pin PCI-E connector into the 8-pin socket on the motherboard -- which clicks in and fits on the left most side, but to no avail as well
- Swapping out VGA / DVI / HDMI cables on each GPU
- Discharging the motherboard using a screwdriver on the CMOS battery socket (with it removed, obviously)
Is there anything I could be missing - anything at all? This is the first time I've ever wired my computer up to an entirely new power supply, and I may have failed to recognize a few things in the process. Any help is extremely appreciated, and I can provide pictures if needed.
