Recent problem, only happens after I'm grinding out a video game for 30 minutes or more... otherwise stable even with typical computing / some minor strain (photoshop + word + winamp + xfire + aim).

but consistently, after a while of gaming it shuts down.

First off, would this be power supply or motherboard? There is no BSOD, it does not reboot...just straight shuts down.

Specs: ePower 500w, gigabyte 965p-ds3, e6530, radeon 4850, 2 250gb WD drives, 2gb of gSkill pc800. overclocked to 3.0, tested stable under p95 with 2 instances back when originally set.

If you are pretty certain it is the power supply...what are some recommendations? (newegg links would be great!). I would prefer something quiet as can be, preferably no lights, and over the 80% efficiency but no big on that one.

Is the newsletter deal on this a good buy (90 and 50 after MIR) http://www.newegg.com/Product/Product.aspx?Item=N82E16817341019&nm_mc=EMC-IGNEFL012009&cm_mmc=EMC-IGNEFL012009-_-PowerSupplies-_-LI3A-_-17341019 (again, if it is 90% or more likely the PSU)

Any help is greatly appreciated! Dont wanna put this off too long - I lost alot of expensive parts last time a PSU went :( lol
 
Thanks for the reply...sadly I got rid of my spare hardware to test with...I may be able to chase some down through a friend or something though.

That is the power supply I have...I see some dead after 1 yr to 18 months....my rig is about 15 months old...so I'd say this seems pretty plausible.

Thank you for the BFG link...I've never bought something from them before - pretty reliable? I've heard largely good things about them in the video card market - wasn't aware they started making PSU's.

Any equivalent in quality recommendations from anyone else that would be a bit cheaper? The shipping makes that BFG a bit hard to swallow - but if its the best for the buck I'll go for it anyway.

Thanks again Zero82z and anyone else who replies!

If you're willing to buy from a different site, you can get that PSU for almost $20 cheaper:
BFG Tech LS-550 550W PSU - $62


The BFG LS-550 is totally worth it at $80. So at $62, it's a steal!

The LS-550 is an excellent PSU: http://www.hardocp.com/article.html?art=MTUxNCw4LCxoZW50aHVzaWFzdA==

It is one of the best deals. However, there is also this Antec Neopower 550W: http://www.newegg.com/Product/Product.aspx?Item=N82E16817103941
It's an excellent Seasonic-built PSU, and has free shipping and no warranty to deal with either. I would actually go with this one if I were in your position (I wasn't aware of the deal when I suggested the BFG unit earlier). The BFG is still better though.

The Antec Earthwatts 430W is also a good choice, although not as good as the other two: http://www.newegg.com/Product/Product.aspx?Item=N82E16817371006
 
Thank you for the help guys. I ended up going with the Antec - as much as I wanted to try out the BFG based on what you're saying...the difference up front (little as it was) couldn't swing this week. I appreciate the link to the other site, but time is of the essence, so I'll take my "next day" newegg shipping for free on this one haha.

Plus - I've had good luck with Antec in the past. Heres to hoping its the fix... lol

Have you removed the heatsink from your CPU to ensure that you have
a good application of thermal interface material between the two?

Most motherboards I've used over the past few years have fail-safes
built in to the BIOS to have them re-boot/shut-down depending on temps ...

It also occurs to me that it could be your video card, or a driver conflict issue.

If it were me, I would do a new format of Windows before I bought a PSU on the chance ...

My two cents, hope it all works out for you :cool:

My first thoughts were these points....but my temperatures across the system have been fine each time I rebooted and checked in BIOS (so unless its a strictly motherboard problem, it shouldnt be of concern).

I'm always very lazy with drivers updates, and havent changed any drivers since I initially installed windows last lol. I've been able to play hours on end of COD4, conquer COD5 SP, ad beat Crysis Warhead without a hiccup. Again, without any change to drivers of any type - the problem has suddenly showed up in 2 of those games that werent a problem before.

I suppose that the video card itself could be the ailment...but that would be especially sad since its only about 3 months old :( lol

I did however already order - so I'll post back on results!
 
power supply did not fix the problem...

heres to more indepth testing and hoping it isnt a motherboard! lol

Thanks for all the thoughts despite!
