Hey all, I've had a 500 watt power supply in my rig for around 3 or 4 years now. I upgraded everything except for the PSU around 6 months ago. Was playing BF4 today and my computer completely shut off, something that had never happened before. I removed the side panel and everything inside was very hot. Whenever I try to turn it back on nothing happens or lights up. Only signs of life are the CPU fan move very very slightly, as if it were trying to spin, and my keyboard also flashes on when I flip the power switch (which is the norm). I've checked all connectors and cables, everything is fine. What do you guys think?
For a system using a single AMD reference design Radeon HD 7950 graphics card AMD specifies a minimum of a 500 Watt or greater system power supply. The power supply should also have a maximum combined +12 Volt continuous current rating of 30 Amps or greater and have at least two 6-pin PCI Express supplementary power connectors.
Total Power Supply Wattage is NOT the crucial factor in power supply selection!!!Sufficient Total Combined Continuous Power/Current Available on the +12V Rail(s) is the most critical factor.
Overclocking of the CPU and/or GPU(s) may require an additional increase to the maximum combined +12 Volt continuous current ratings, recommended above, to meet the increase in power required for the overclock. The additional amount required will depend on the magnitude of the overclock being attempted.
Ultra LS Series 500W (ULT-LS500)
• OEM: ShenZhen RuiSheng Yuan
• maximum combined +12 Volt continuous current rating of 28 Amps
• one 6-pin PCI Express supplementary power connector
• No 80 PLUS Efficiency Certification
Two signs of an insufficient PSU for your graphics card in your system configuration.
I think you've overstressed the PSU and now it's defective.
Sorry for all of the questions, PSU is really the only component that I'm pretty clueless with!
Corsair CX Series Modular CX600M (SKU# 75-002018 / CP-9020060-NA)
• OEM: CWT (Channel Well Technology)
• maximum combined +12 Volt continuous current rating of 46 Amps
• two (6+2)-pin PCI Express supplementary power connectors

That's more than enough to power your system configuration.
