GTX 480 Overheat & Shutdown

[DoubleKill]

Hi guys recently I bought a new PSU
which is quite cheap, but saying its 750w.

I put it all together within my pc with this specs :
Intel I3 - 3120
6GB RAM DDR3
500gb hdd
INTEL H61m/u3s3
Evga GTX 480 1.5GB
Normal case

And this PSU.

Temps in idle are about 80.
In gaming league of legends at ULTRA 1920x1080 it's 92degrees.
But when I started furmark with normal test it gets above this temperature and shuts off.

I tried changing the thermal paste with ceramique one on cooler master's.
cleaned heatsink and fan and the same problem applies.
No change in the temperature just pc shut off after the furmark test.

Is the psu suspicious or the card itself?

The PSU is very bad. Dont go for cheap ones as they're really not worth it.

have you problems other than using furmark?

reapply thermal paste, don´t use too much of it. Just a pea on the middle of the chip.

replace the psu, it could destroy your hardware and burn down your house

It's just a small amount and I spread it all the way on the chip.
Whenever he play a game it never gets over 92-95, but when furmark is one it shutdowns.

Do not apply the thermal paste like that, just put a little bit in the middle and allow the pressure of the heatsink to do the rest, spreading it can create air bubbles which acts as an insulator thus heating the CPU more.
