My computer has been crashing the past 3 days when I try to game I opened up speccy and seen my CPU was going up to 70 °C so I got the Corsair Hydro Series H55 and added that (today of this post) it runs nice a cool but then I seen my GPU working its way up to 61 °C + that's when it ends up crashing I've had the graphics card almost a month it was running fine but it's only the past few days it isn't I have used other PSU to see if it would help but yet it's the same thing again! Please someone help me it's getting me soo mad

Your psu could be dying.
If it's a cheaper psu(with low efficiency),it just might be that it has trouble powering your rig.

There are a number of factors that might lead to your problem.
A GPU at 60 ° would not normally crash a computer via heat (650ti Boost maximum reported to run at 97°).
We need to know the exact model of PSU(s) you are using, if it is a rubbish one it won't put out 500W so its under strain. Or the PSU itself is getting too hot and or is possibly giving the GPU hot air intake.
What is the rest of the cooling like in your case?

I'm not sure if it could be that as I've tried using some other PSU as well what type of PSU would be best for this build? I don't wanna be going for any stupid priced ones

^ Agreed, first thing I would check is the PSU.

I know you checked another PSU but that PSU could also not be up to the task of powering your rig.

Cheaper PSUs are just that, cheap. They claim to support X watts but in reality they have no ability to handle that power draw consitantly, let alone with any efficiency, so that 500w psu might only handle 350-400. Also a psu suffers from what is called capacitor aging, overtime the capacitors loose the amount of charge they can hold so in a year (if it has heavy gaming or is on 24/7 especially) your PSU can loose 15-20% of its ability.

Just get something @ 500W with high efficiency.

That has good specs,good price and favorable reviews.

Is the minimum I want for a power supply @ 500W? or could I have something lower or won't it work with my build?

I suppose you could go even lower.Personally,i wouldn't go lower than 450W(maybe 400,although i wouldn't risk it for a $25 gain).

I'm using a 300W for now (lol) it's only till I get paid Tuesday then I can order a corsair 500W

Well then you'll have to wait
