It's possible you have exceeded your power limits. Especially if the FX CPU is overclocked, as they are very power hungry.

It's also possible that you did something else while installing your LED strip.

Return everything to default clocks and unplug the strip. If everything works fine, add one thing at a time until you figure it out.

it sounds like he did something while installing the LED strip... even with a OC on both his CPU and GPU to the limits of air cooling, it really shouldn't go over 350-375w of power draw....

There are some differences in the various Corsair CX500 models as I recall.

Yes, the older ones are only rated for 34 amps on the 12V rail.... 408W.

That's not to say the problem is the PSU. I'm just making the point that it's within the realm of possibility. I agree that the system is not likely to actually need 34 amps, unless something is wrong.
