I have a AMD radeon 6950 and when i go into a game i can play for a few minutes but then my screen goes black and i am forced to switch my computer off from the power button. Im guessing its the gpu because when i lower the power limit in msi afterburner and lower the clock speeds it fully works but has a major impact in performance.

My specs:
Cpu: Intel Core2 Quad Q8300
Gpu: Amd Hd Radeon 6950 (Sapphire)
Motherboard: Gigabyte GA-G33M-S2
Ram: 4x2 DDR2 Ram 800mhz
Hard Drive: 150Gb
Solid State Drive: 60Gb
Cooler Power 750 watt power supply (Found out it is only outputting 600-650 watts)
Os: Windows 10 Pro

They are good for that kind of temp.

What's the model number of the PSU. It could be the problem, but you are well aware from what it says it's capable of, and what it might actually be capable of it is overstating what it can do.

Not a single review on a trusted review site, that's my big red flag.
They don't appear on any PSU tier list (flawed as they are) even as a brand.
They have no webpage that I can find.
It all points to a problem PSU.

When it goes wrong it can really go wrong:

I didn't spot they had the GX850 in the mix.

Failed between 500 and 550W.

Another giveaway is the 1x6pin and 1x6+2pin PCI-E connectors, an 850W PSU should have 4x6+2Pin minimum, maybe 6 being optimistic
