sauria Posted March 30, 2014 Share Posted March 30, 2014 Would a Corsair AX860 power supply be smart enough to not turn on if the CPU fan/pump failed!? This is a new build with a Swiftech h220 cooler and the pump doesn't work. When I try to boot the new build with the AX860 the case fans won't even move and no post, it just lets the LED light on the logic board glow -but no more. Swapping the AX860 for a known working PCPowerCooling turbo cool 510 SLI would let my system POST. The bios comes up with a warning about the CPU fan. Case fans turn on. Is this new AX860 PSU bad? I've tried it with two different motherboards with the same result. Thanks! Link to comment Share on other sites More sharing options...
Corsair Employee jonnyguru Posted March 31, 2014 Corsair Employee Share Posted March 31, 2014 The PSU is told by the motherboard when to turn on and when not to turn on. It's not "smart" enough to know if there's a problem somewhere else unless the motherboard tells it there's a problem somewhere else. Link to comment Share on other sites More sharing options...

Ok, thank you, so it would know if the motherboard told it that the CPU fan was not working? Link to comment Share on other sites More sharing options...
Corsair Employee jonnyguru Posted March 31, 2014 Corsair Employee Share Posted March 31, 2014 Yes... BUT, it wouldn't explain why the other PSU works. It should be just as "smart" ("dumb"?) The PSU is technically "always on" (unless there's a short, of course). The reason why the paper clip trick works is because that wire (the one that's typically green) is the one that the motherboard uses to tell the PSU it's ok to turn on.

Thank you, I will keep investigating. Link to comment Share on other sites More sharing options...
