Computer shut down when running bench mark and stays off

[veisien]

hello, i just recently updated my old computer hardware.

computer spec:

Gigabyte 970 gaming sli
Asus gtx 760 2gb oc II
AMD Phenom II X6 1045T
Kentek psu 750
Samsung evo 120gb
CORSAIR Hydro Series H60
Cooler Mastarbox 5t

Upgraded

second: asus gtx 760 2gb oc II sli mode
amd fx 8350

after the upgrade computer works fine i started tomb raider 2013 and tried to run bench marks and the computer shut down and stays off, i tried multiple times same results. Overwatch too. i have't even tried to play them, league of legends runs fine with highest video setttings.

and also the chipset/northbridge, the one near cpu is hot i can't even touch it for more than 2 seconds

i don't know if it the chipset or the power supply

Cpu temp doesn't go above 55

You should stop use that PSU, buy the good brand PSU ASAP.

i am ready to order this power supply would it be good for my system
Rosewill Hive-1000, Hive Series 1000W Modular Power Supply, 80 PLUS Bronze Certi
and why is the system temperature higher than cpu temp, northbridge feels like it on fire, my intel computer doesn't get hot at all, sorry if i am doing the forum things wrong, my first time on the forum

1) You don't need a 1000W PSU, but it does not hurt either, a good brand 550W or up that will be more than enough. If you post what budget you have and where you shop, we will find one for you. Usually we use the pcpartpicker.
