New AX1200 - Low Output

Recommended Posts

After buying Corsair products for well over the last decade I've finally had to come register and ask a question. Guess I can't be to frustrated. :D:

 

So here we go, I'm replacing some gear that met an unfortunate demise (water is evil.). I bought an AX1200 yesterday in the process (is the extra vowel worth the $90 or so bucks?). And it doesn't seem to want to power my board and things attached.

 

All I'm getting is click-clunk sound out of the PSU when attempting to turn it on. I decided to try jumping it quick, but the fan didn't move. The click was different so I added the H100 to it. Which did make the PSU fan move.

 

However, it was barely lighting the leds on the H100, and the fans were not moving. I was not completely sure if this was normal (seemed odd) so I added a couple chassis fans on another leg. The little ones moved, but not the big 300mm, nada. Hmm...

 

So I screwed around for a couple more hours checking wires, pins, reseating a cpu (which was fine...) and all that good stuff, to no avail.

 

I decided to kill more time fussing about with the device by removing it from the equation completely and found an old PCP&C 750w unit in closet, hooked the H100 and all the fans to it. Jumped, and evertything was blowing. H100 lights looked like normal, fan speeds worked, 300mm spinning, yada yada.

 

Am I to assume correctly the new AX1200 PSU needs to return home? I can return it locally, which would seemingly be faster than an RMA process. Any thoughts/suggestion/answers welcome.

 

Cheers,

Hatchet

I would. Somethings not quite right there. At start up the fan should spin, and then stop unitl the load becomes around 40% and 49C are a combination of the two depending on system specs.

 

The click is normal, thats just a relay, but it should be able to power any case fan just fine. The AX series are 0amp PSU meaning that you really don't have to have much load on them at all to get them to fire up.
