    Failing PSU? - HE650 Blue

    Hi guys, so my current rig has been running quite happily for a couple of years, but over the last month or so, it has started acting a little erratically - segfaults here and there.

    The first thing I did was fire up memtest and prime95 and found no issues there but I decided to drop the o/c down anyway (I'm actually running stock now: 90% of the time I didn't notice the difference). This was fine for a bit, but yesterday I fired it up, logged in and my X server hang (the gui bit on a linux box), so I opened an ssh session to it, rebooted it and tried to log in again - same deal (note the box didn't hang, just the gui).

    I hadn't made any changes to the system (drivers, etc), but decided to boot up a windows install I have on another disk and found exactly the same (log in, but as the desktop is initialising, the pc hung) - so it seemed the gfx card (GTX460) wasn't happy going from 2d to 3d mode. I whipped it out and popped in the trusty standby - a nvidia 8500 and everything was tickety boo and I'm thinking "yay, time to RMA the card ". To be sure though, I tried the 460 out in another box, expecting the same... except once I'd installed drivers (and was out of a 1024*768 resolution), it worked fine. In fact, I fired up Far Cry 2 and ran around for a bit just to be sure.

    Now - considering that memtest and prime95 could run for hours (prime was running happily for 24+ hours), I'm inclined to believe that it's not the processor or ram that's at fault here. I connected the power supply from the other rig (which was a huge pain, considering it was still in the other rig!) and although I successfully managed to get the box fired up to a windows composite desktop (3d mode), which is a lot more than I've managed in the last two days. The older style borrowed PSU wasn't powering my CPU fan (20 + 4 pin connectors instead of 24 + 8 pin), so obviously I wasn't really that keen on any heavy testing...

    OK, so that's a long story, but to me it certainly looks like the PSU is at fault and for some reason can longer supply the power needed for this card on top of the other devices (maybe a failed cap?). This leaves me with two real questions:

    1) Can anyone see an error in my method? The 8500 is a substantially lower powered part than the 460 (it draws all its power from the pcie bus, whereas the 460 requires not one, but two additional six port power inputs).
    2) Assuming that the PSU is indeed at fault, what is the RMA process? I bought the part from eBuyer, however they have informed me:
    "For warranty repairs please contact Antec direct. Telephone No : +31 (10) 462-2060 Web : http://www.antec.com/uk/supportRMA.html Email : europe.techsupport@antec.com"
    ... although the page mentioned don't appear to exist.

    For reference, my specs are:

    AMD 720BE
    Gigabyte MA790FXT-UD5P
    1x Seagate 7200RPM <something>
    3x Samsung F2 EcoGreen
    1x Samsung F3
    1x CDRW/DVDRW
    Some fans

    So even according to Antec's own PSU calculator, there should be more than enough juice available, even after 3 years.

    I of course could try emailing, but I thought that I would try here first in case anyone had any gems of information.

    <EDIT> Sorry for the wall of text!</EDIT>

    Re: Failing PSU? - HE650 Blue

    Woo. Borrowed a Corsair TX650 from a friend and get the same results with that. Can a mod please close this? I'll take it up in another forum as it doesn't appear to be the PSU after all (which both confuses and annoys me, as it seemed to work with a lower spec'd - and much older - Enermax) :-/

    Incidentally - as I didn't get any response from the mods here and anyone is interested - the RMA procedure above (including the email address) is wrong - there is a webform @ http://www.antec.com/Believe_it/EUnewticket.php
