PSU not enough for my Graphics Card?

[iRyzza]

Let me dive straight into my problem..

I have a 500w power supply (There's not brand on it, It came with my PC 2ish years ago.)

I've recently bought a GTX 660 Graphics card, everything went perfect until... I started playing games. As soon as I would get into the game, set up my graphics, within 2-10 minutes (time varies with different games) My whole computer would switch off without warning, and then 1-3 seconds later switch back on with no indication that anything went wrong.

It can't be the Temperature or my GPU or CPU, as the game doesn't stay on long enough for the whole thing to crash.. I think.

Should I upgrade my PSU to a 750w power supply or something?

Any reply would be massively appreciated.

its not the wattage thats the problem - its the quality

get yourself one of these:

OR if you think you need more wattage, choose one from this list here:

You need a decent PSU. El-cheapo no name PSUs *IF* they put out 500W, usually put it out where at a voltage that's useless in most modern systems.

A decent reputable 450W will run most single GPU systems without breaking sweat. Expect to pay £45+ for a good quality PSU.

Thanks for both of your fast replies.

I was looking at some of Corsairs products, but most of them are out of my price range as I'am sort of... broke. Ha!

I was thinking of buying;

No competitor links.

Suggest you remove it before you get a holiday from the forums.

Oh, and I wouldn't touch a CIT PSU with someone else's bargepole.

 

[iRyzza]

Damn, really?

From what I've herd, they are pretty decent.

I quote 'Best component I've ever bought! Bang for my buck!'

Why don't you recommend CIT PSU's?

 

[MagicBoy]

They're ****.

Oh Damn! So you think I should wait it out and invest in that corsair, or do you think It might be something else than the PSU?

 

[MagicBoy]

It's most likely the PSU. It'll be tripping out when the load increases which is typical of a cheap PSU. Carry on using it in such a way and it may eventually damage your components.

Wash some cars, or take your own lunch to work for a few days. Anything to get the extra £20 for a better quality PSU.

Thanks allot for your help! I've just spotted a 600w Corsair power supply for 53 quid! Going to buy that! Thanks again for your help, I've take it you seen this sort of problem before?

This sounds (99%) like the PSU is struggling. Get a quality one, it isn't worth scrimping on a PSU

Ok guys, arrived today after a week or so, Installed it this morning, playing GTA IV at 60+ frames, hasn't crashed in at least 30mins, a new record so far! Hoping It won't crash anymore, the PSU itself, is running cool and SUPER QUIET! Thanks for all your support this far! Can't thank you all enough!
