Hey Guys,

Since yesterday I have this weird problem with my April 2012 Purchased Corsair HX 850 PSU. Yesterday I got a heart attack when i pushed the power button and the PC didn't turn on, everything else ex. monitor, speakers etc was on.. there was no led on the power or on motherboard. So i opened it up cleaned everything, connected it back & it worked. I was relieved, then in morning i started my computer & it worked just as normal I did my routine work and turned it off. After Lunch when I started my PC again, It wouldn't turn on....same issue, no power.. I tried the switch of the PSU, changed the Power Cable... Connected it directly to the Power Switch instead of via APC BackupUPS Pro 1500. nothing seemed to work. So i disconnected and opened it up again and removed all the connections from the PSU to Motherboard & hard drives, just kept 1 fan connected so i can see if it works or not, i tried the other way of checking psu by connecting the Green cable & 3rd black cable from the opposite side... it still didn't work.

I thought it was dead... so I had to go through the painful method of switch out the smps's. I have a Cooler Master 500 Watts, which is used in my Home Media Server. I took that out & connected everything back to my pc and started that up... now when i was packing the Corsair in the box so that i could give for RMA I thought i should try once again and this time since it was out i could see the PSU Fan on the inside. To my surprise the fan inside was spinning. So what's wrong? Why was it having problems?

The APC Backup UPS Pro I have shows me exact usage in Watts, My i7 on idle only consumes about 160 watts, this is including 2.1 Speakers, 2 LCD Monitors, 1 Switch & 3 Routers all connected to that UPS. So I am sure I am not Over using the Corsair HX 850, I only have a 9800GT card in there.

Should I give it for RMA? & Will Corsair accept it as RMA? as it seems the fan is spinning now on the PSU?
 
RMA it.

Will Corsair accept it as RMA? as it seems the fan is spinning now on the PSU?

Why wouldn't they? There seems to be no output from the power supply so that warrants an RMA. As long as there isn't any physical damage to the unit.
