PC shutdown while gaming - GTX 970, PSU Problem?

[Flea_]

Hi guys, I have a problem where I try to play a game or even run windows experience index - my PC shuts off. I just got a new GTX 970 (asus strix).

Here's my specs:
Asrock x79 Extreme 4-M Mobo
Intel i7 3820 (CPU Cooler-CoolerMaster EVO 212 35? idle - 50? load)
G-Skill Ripjaws 8gb (4gbx2)
GTX 970 - Asus Strix
Samsung Evo SSD 250GB
WD Black HDD 1TB
TOSHIBA HDD 500 GB
DVD Drive
Thermaltake SMART 550w 80 plus Bronze

I had an old gtx 460 card, before installing the new 970, I removed all old drivers, clean install etc. I have good case ventilation/cable management. None of my parts are overclocked (minus the 970 which is factory OC). Here's the specs page for my PSU http://www.thermaltakeusa.com/products-model_Specification.aspx?id=C_00001975 Im not too good at this, Is the problem my PSU or is it something else? Please help me.

the power supply is a known brand that not that good. look at cosair or seasonic or evga for power supplys.

I'd suggest a new PSU. I recommend Corsair or EVGA. Anywhere from 600-700 watts should suit you well. If that doesn't fix the issue, you may have a larger issue on your hands, but we'll be here to help with that on the forums if so. Good luck!

Thanks, it was the PSU. I've already ordered a 700w seasonic 80plus plat. I found out that the thermaltake smart series were one of the worst psu's on the market. Never buying cheap psu's again.
