Well i have MSI Afterburner and also am Benchmarking with Furmark. However if i add ANYTHING to engine clock after between a few seconds and a minute of furmark (at 1680x1050 resolution), the pc will shut off.

I have noticed with my GFX card that:

* untill the card temperature hits 70*c the fan stays in idle, and only goes up a small amount after that.
* The graphics card has never gone above 72*C and very rarely gets above 65.

Is there some sort of setting i need to fiddle with to allow GPU overclocking. In the few moments i get to see, i do notice a FPS boost in the performance but it's all for nothing if i'll only get a few seconds before meltdown!

This.

It definitely sounds like your power supply can't keep up with your graphics card.

No, not all 750 watts are built equally.

Depends, cheaper 750W's can only supply 500W, or less, in heavy testing, so just because it says 750W, it could well just be a rebranded 500W. What model is it exactly?

Brand is very important. Cheap or off-brand "750-watt" models might only be stable up to 450 or 500. (I hate marketing btw.)

Corsair and Antec produce quality PSUs. I've also had decent luck with Rosewill, though they are usually looked down upon as a "budget" brand.

a no name psu is like buying a used condom. sure it will work, but its not exactly a good idea.

that psu might be supplying 750w but how efficient is it, how about reliability?

Ahh i had a look through the window and it says its a "WIN: POWERPLUS" "Powerful and extemely Silence".

The grammar error has got me a bit worried.

Your PSU is the problem. Get a quality unit (not a flashy ebay knockoff) and you should be set. Give us a budget and we will recommend a good PSU. It is highly recommended you get that thing out of there ASAP. If it can't even handle a 1055t and GTX460 it can't handle squat, and if/when it blows up, it could take all of your hardware with it. You NEVER skimp on the PSU.

Budget wise, something between £20-£30 ideally, and maybe £40 if absolutely necessary. Whats strange is, after the crash the settings have defaulted to normal, but five minutes ago with no overclock settings it turned itself off again :/

someone on this forum suggested i get a XFX 750w modular psu. they're about 110 after rebate on newegg and apparently its designed by Seasonic, which i'm guessing is a decent manufacturer.

You won't get a decent PSU for that really, which is probably why you ended up with what you have now. You could just about get a corsair CX400 for £40~, which should do the job although you may be more comfortable with some headroom.

I'm selling an Antec TruePower 650W, a well regarded PSU, which will easily do your PC, and I'm in the UK. I don't need it, so I'll let it go pretty cheap, drop me a PM and we can sort out a price.

It is not watts it is how many amps on ur 12v rails man .. generic cooling Sucks too ... so sounds like a combination of problems bro, what kills computers???! HEAT HEAT KILLS MAN! So looks liek ur oiwer supply is crashing and then flat lining... like u will run the game fine and then 5-10 mins in BANg it is over turn off or frozen .. i had a generic 430watt running a x1900xt and it would do this untill i moved it close to my AC unit and then it would be fine ... i spend i think 120$ on a 700 OCZ ps and was fine after that ... I say u spend LEss then 50$ shipped and fix this:

No, do not touch that Thermalcrap TR-2. That is probably a 300w unit, and those are an ancient, obsolete design that actually violates ATX spec (-5v rail is not allowed by spec anymore)
If you want thermaltake, get a Toughpower, otherwise get another brand.

Here's an easy way to tell whether the PSU is the problem in this case.

Fire up something that's intense on the CPU, like Prime95 or Orthos or SuperPI. Make whichever you use to run on all 6 cores so you really use up the juice. Leave it running in the background.

Then with the gfx card at stock settings, fire up a full-screen window of Kombustor or Furmark, use the stability test. If the issue is the PSU, your PC should pretty much just shut straight off, like hitting a switch.

If it doesn't, the problem lies elsewhere, because there's no way that overclocking your gfx card and running a 3d test is going to add as much power draw as you will have added by running the CPU test concurrently.

Now, this is not to say that you probably shouldn't replace that PSU anyways, but ... if funds are tight, and you want to target your efforts, I would do the test I describe above.

The XFX PSU's are very nice, as you heard they are Seasonic-built, which is a great OEM. You really don't need more than the 650W version but if the $ difference isn't that much, the 750W might make more sense for the long-haul.

Thats what mine was doing before it totally failed, took my damn RAM and Motherboard with


REPLACE IT ASAP

I should have replaced mine when it was turning off randomly while gaming, but I didn't and I had to replace $300 worth of stuff
