Hi,

Bought a new pc last month,

-Sapphire ATI Radeon HD 6950
-Corsair PC Starter Bundle 1000c - 600TM Case / TX 650W V2 PSU / H60 CPU Cooler
-Intel Core i5-2500K 3.30GHz (Sandybridge) Socket LGA1155 Processor
-Asrock Z68 PRO3 Intel Z68 (Socket 1155) DDR3 Motherboard
-Kingston HyperX Genesis Grey 8GB (2x4GB

So this worked fine for a month or so, until last Saturday when I powered on the pc, went downstairs for a cup of tea, came back and found the pc was powered off... it went back on again, and I used it for an hour or so, playing a game, when it shut off completely out of the blue. It wouldn't go back on. I played around with things for ages, including CMOS resets and eventually got it to go back on. It shut down again, and again wouldnt power back on.

I took everything non essential out (GPU, all but 1 hd, even the ram), even running the motherboard out of the case to see if it was a short, and it still powered off.

I tried the pc with an old Seasonic 430 watt psu and it seems to run fine with this. The only thing that has me unsure is if i try the new PSU, and then swap to the Seasonic, the pc wont power on until i flip the switch on the psu a few times on and off. Then it starts up and works fine.

I tried the new psu with the paperclip test, and it powered on ok first time. I've done this test a few times and sometimes it wont power on. I tried to check the voltages with a multimeter and the PSU wouldn't actually go on with the multimeter probes attatched. If i get it running and attatch the multimeter, the PSU shuts off.

I *did* get it working once and I was getting something like 6.8 volts on the 5 volt line and 14.8 on the 12 volt line, which was shocking, but I do get the same sort of results on the Seasonic psu, so I think it's just a bad multimeter.

I tried to power an old pentium 2 with the new PSU and it wouldnt power on. swapped straight to the old Seasonic and the machine turned on without issue.

It does look like it's entirely the Corsair PSU at fault, right?
 
Yea, looks like your PSU is shot dude. Please tell me you got it from OCUK!!! They are great for RMA's.

Give them a ring or do it online. RMA the son of a *****! Get a new one pretty quickly!
 
Yep bought from OcUK but looks like i'll have to send it back to Corsair directly :\ bit of a pain, have to put this Seasonic spare back in another pc (it's on loan from my Dad's pc :p ) so i'll be without a working machine for 2 weeks I reckon :(
 
Hmmm... over the 28 days I think you can return it to OCUK then. Not sure on that one, but sure it's 28 days.

Well do you have to send it to a UK base or USA?

If USA, I feel for you!
 
Hopefully if it is a UK return, it wont be too far after the 30 days, and you might be able to sweet talk your way into it
 
£30? wow :| do you get that back at all? It's a bit rubbish if you have to pay 30 quid to get something fixed when it's still in warranty..

I did apply for the RMA last night, just didn't have time to send anything off today. I just tried the PSU now and of course it's working.. I know if I put it in the pc for an hour or so though, it'll shut off. I'm assuming the Corsair guys will be able to get the same result and not just send it back to me going "eh it's working.."
 
I'm afraid its up to the end user to get it back to Corsair. Quite expensive to send due to the weight and the box size, it's calculated by volumetric weight.

The turn around was approx 2 weeks, I did get a brand new PSU returned.

Also remember to remove the Case PSU mounting plate! I forgot and had to buy a replacement for £10. I contacted Corsair to try and locate the plate but no joy, probably not interested?
