Found 9th Jun 2011
I have a problem now. Whenever I try to play a game or watch a video the computer shuts off completely including the power supply.

I'm guessing it is the power supply.

I have an EzCool 600w power supply with 12v1 12v2 12v3 12v4 at 18 amps each. The card takes two of them I believe (2 6 pin) and needs 18.5 amps alone. I have a C2D E7600 and 4GB ram. Resolution is 1080p.

Anyone let me know if it is the PSU and I should get a new one please?

Graphics card is a GTX 275

I used an antec calculator and it came upto 404w if that helps.

It's a XXX OC edition for £50 good deal?

600w wouldn't be underpowered would it? Try running some stress tests and monitor your temperatures. You might need some better cooling.

Original Poster

Temperature of what?
Idle
CPU 39C & 30C
GPU 54C
I don't know what the temp is when it isnt idle as the PC shuts!
I was running minecraft with no problem lol so i dont see why it turned off when on YouTube.

How would I do stress tests? I do think the airlow isn't great it's a mATX mobo in a full size case

Depends upon the age of the PSU i thought as age lowers the throughput but shrug still new to the O/c scene.

Ah i see thanks.

Stress test would be prime95 for the CPU and furmark for the GPU. This will up the temperatures so you can monitor how hot things are getting when you are playing a game for example. You will need to use a hardware monitor aswell. CPUID for example.

If I can I will try that out today, but I don't wanna damage the card in any way.

I have done it just don't run it for too long as it does get it bloody hot lol. If heat is causing an issue you will soon know about it. Run one test at a time. Prime95 will need to run longer. Open the case and just check none of your fans have failed. If you think it could be a heat issue try running the computer with the side panel off with a fan blowing in it or something. This will rule out temperature as the cause with any luck.

If it still turns off its probably the PSU.

Currently have the PC on with the side panel off and fan blowing in.

Temperature
CPU 39C
28C (Consistent before it would go up to 41 sometimes even 50 from youtube videos)
GPU upon start up it was 40C now on Hukd it is 45C that is a big decrease from 54C.

Now going to start up a game and play at a lower res! *fingers crossed*

Left 4 Dead 2 1366x720 no problem.

Temperature of GPU is 56C CPU is 39C and 31C (game minimized) not sure if that will make a difference.

I'm possibly gonna try a higher res and GTA 4

Original Poster

When I clickly switch and look CPU is 41C 38C

Original Poster

GPU going to 65C on 1080, I tried GTA 4 720 played roughly 5 minutes managed to get an achievement then the PC powered off :(. Any ideas?

Original Poster

Also I was running the games pretty much maxed out and just realised I had it set on power saver mode will this affect it? Either way i'm going to look out for a new psu and sell this.

Well 65°c is fine for the GPU. I'd not worry till you start breaking 80. … Well 65°c is fine for the GPU. I'd not worry till you start breaking 80. Most likely the PSU but unable to say 100%.



Do you think the power plan affected it?
It's running without the fan side off at 48C, CPU at 39C & 32C.

Yeah the temperatures sound fine to me. No problem there. Must be something to do with the PSU then. I can't think of any other reason why the whole system would turn off.

If it were RAM or the motherboard would it just power off like that? I'm not really sure. You could run the windows RAM diagnostics to rule that out i suppose. Start > control panel > system and security > admin tools > memory diagnostics.

Any chance there is anything to view in Event Viewer that might indicate what the problem is?

Original Poster

Will check out the ram now.

Well when it's on power saver my e-on plug keeps turning it off and on which gets on my nerves so i've set it to balanced.

Also i've just been playing on minecraft for well over an hour with GPU temperatures of 58C. So minecraft gives it no problem. (I know minecraft is not at all demanding).

Just critical errors at the times of shutdown. Warnings and errors (Microsoft-Windows-Setup terminated or something similar).

No memory errors, so are you suggesting a new PSU?

Motherboard maybe? Or PSU. I'm not really sure. My computer used to blue screen on one certain game. The whole machine would lock up and shut down. It was down to Easy Tune 6 - overclocking software from gigabyte.

Yours seems like a more general problem with games. You could try updating your graphics drivers and updating the bios. It's worth a try as a last effort before you start replacing things.

Can't be motherboard as i've used a different card before though that did blue screen on me.
How do I update the bios? Have updated the graphics (first thing I did).
How many amps on 12v rails should I be looking for?

Ok fair enough. Rule out the motherboard then. As for the PSU I don't really know what you need to be honest. I'm not very clued up on it.

Thanks, I can get this highpowerplus.com/650…htm for £35.
It's 20A on 2 12v rails and 80+ certified. Should I go for it?

It's 80+ certified surely that's all that's is needed according to most websites.
A better brand will put me £20 extra i've already spent enough.

That seems better than mine haha.
I have one with 3 12v rails at 18A silver coloured

That's the thing it is a clean OS install hah! With the side panel on i've got 37C now it's on 44C so it's definitely not a temperature issue. Will update what happens with the new PSU.

Thanks alot btw

Got my PSU today, played GTA 1080p for an hour or so no problem, air coming out is quite hot and temps are around 80C to 86C which i've heard are not too bad. CPU temp 40-44C.

P.S I didn't think GTA could get better :O
