Hi guys!

I have a problem with my computer.
It suddenly turned off three times (it started about a week ago).
The event happens only when i'm playing games (first time when i played FIFA14, last times while playing CS:GO).
First two times after the shutdown it turned on automatically, but now last time it wasn't. I had to turn the switch off then on.
I ran FurMark and HeavyLoad, but everything was fine.

My specs:
Gigabyte B75M-D3V
Intel Core i5-3470 (with CoolerMaster X Dream i117)
ASUS DirectCU II 7850 2GB Top V2
2 x 4GB Kingmax DDRIII 1333MHz
WD Blue 1TB
Gigabyte SuperB 460W

Most of the components are new, except the 2 memory sticks and the PSU. The PSU is about 5-6 years old.
Thank you in advance for your help!

Are you sure?
It's interesting. I thought system draws more power under stress test than gaming.

After 5 minutes of Prime95: CPU
And after 5 minutes of FurMark GPU goes up to 75 Celsius.

Open event viewer, look at windows logs -> system, look for Event ID 41 - Kernel Power "System has rebooted without cleanly shutting down..." around the time of day that a restart occurred... If these are showing up every time a restart occurs it's almost certainly your power supply...

It doesn't seem like a very reliable PSU, I'm not familiar with them personally but "Gigabyte SuperB" PSU's aren't even listed on the power supply tier list:

This is in the event viewer exactly!

In fact it has FSP inside. What PSU do you suggest to me for this config?

Pretty much anything tier 3 and up on that power supply tier list I linked... I wouldn't go below 550w or 600w. You could start by looking at power supplies in your desired price range on newegg or whatever website, and if you find a suitable unit look at the tier list and see where it's ranked

You just have to make sure whichever power supply you get has the proper connectors that your system requires (i.e. 24 pin mobo connector, 4 or 8 pin mobo, 6 pin gpu, etc)

I was having the exact same issue with an 800w "Coonix" power supply, I purchased this ( http://www.newegg.com/Product/Product.aspx?Item=N82E168... ) and it's been great.

Good PSU, it'll be enough although if you want to do some heavy upgrading in the future 450 might be cutting it close
