I have looked on many forums and they are all saying it's a PSU problem but I just want to make sure this is 100% correct before I spend money. All of my temperatures are fine, my CPU never goes over 50c when playing any game.... my GPU temps are fine as well... when I Alt and tab the temps are about 80-85c. Do I have enough power for my system?

Processor: Intel(R) Core(TM)2 Quad CPU Q8400 @ 2.66GHz (4 CPUs), ~2.7GHz cooled by Corsair H50 CPU cooler

Memory: Corsair XMS2 1066Mhz 4096MB RAM

Hard Drive: Seagate 500GB + Samsung 1TB

Video Card: XFX ATi 4890 OC ( 870Mhz GPU clock - 975 Memory clock)

Operating System: Windows 7 Home Premium 64bit

Motherboard: Gigabyte GA-73PVM-S2 GeForce 7100 Socket 775 mATX Motherboard

Computer Case: Antec 900 hundred 2

PSU: Storm 700w

This is my PSU I have at the moment :- http://www.scan.co.uk/products/700w-storm-lpk19-35-120m...

it's not a good PSU. i doubt it could ever supply 700w, or even 500w but your system doesn't use anywhere near that at gaming. It probably is the PSU but I would play around with the drivers just to make sure its not them.

i strongly suggest a quality PSU rather then the cheapest one that "offers" a lot of power.

Before buying a new PSU (I recommend Seasonic), reduce your HD 4890 to stock speed to see if your PC continues to shut down.

Antec PSU

Corsair

XFX

Take note some PSU's are modular other's are not. Check the specs of the PSU before making the purchase.

My personal preference since last year is Corsair... Well that's me(My PCS are on 34x7) you have to make your choice. Antec, Corsair are great PSUs.

he's in the UK, different supply, different demand, different price structure

Electrical Power in Watts is the same...Your PC will consume the same amount of power here in the US and in UK. PC PSU are auto Volt and multi freq 50HZ EU or 60 HZ US. Make your pick any PSU above 500Watts.

We can't do anything about the price structure in UK. You have to choose the best that would work for you.

Same thing... Antec and Corsair are one of the best supplies for PC.

oh my god you are an idiot. i am talking about product demand and product supply, not power demand of PC hardware and power supply. how the hell did you come up with that conclusion? didn't the words "price structure" tip you off that I was talking about purchasing products?! :pfff:

Generally no.

Only some of the more expensive ones ($125+) are considered good because they actually use a decent OEM manufacturer to make them.

Lost faith in Antec power supplies just had a 650w earthwatts failure, took a M/B and possibly the CPU with it, 2nd Antec power supply gone bad in a years time period, about the only thing I'll buy Antec wise now, is a computer case.

I recommend Seasonic, Silverstone, and PCP&C, not necessarily in that order, those are all solid brand name power supply companies and I own and use one of each or I wouldn't recommend them.

Its hard to make generic statement to cover all models. Its always a good practice to review specific brand and models. Since not all model from specific brands are good.

Sites like this will provide you with more insites on the specific hardware...There are other sites that provides similar or equivalent reviews.

User has to consider its specific needs and preference.

As on my other posts pertaining to PSU... My personal preference is Corsair. Cost is not an issue. The computer downtime is more expensive in my case than the cost of PSU. Higher reliability is more important to me. I have 3 machines that run 24x7 for different requirements/needs.

Corsair is my personal favorite... Both my son and I have the VX550 and our systems are on 24/7....Never a problem...and they are now about 2 years old and going strong!
PC Power & Cooling are also top supplies....
The feature I like best is the single +12Volt rail....Mine gives 42 amps and my brothers PCP&C silencer610 gives 60 amps.
Hope this helps!
