Computer shutting off randomly after graphics card purchase

[mralbania]

Yesterday at 12 am I hooked up my EVGA Geforce gtx 760 graphics card after work, I plugged it in, power the bad boy on and it runs. Install everything, now its time to play games.

Fastforward to right now, I was playing Sniper Elite V2 and the computer just randomly shuts down, this did not happen with my intergrated intel hd 400 video card(was trash). This never happened with my Geforce gtx 460. I touch the psu, i can feel some heat, but it isnt to hot. Im not sure why its doing this. Here are my specs (dxdiag and typed):

Processor: Intel(R) Core(TM) i5-3570K CPU @ 3.40GHz (2 CPUs), ~3.4GHz
Memory: 8192MB RAM
Available OS Memory: 8076MB RAM
Video card: EVGA geforce gtx 760
DAC type: Internal
Display Memory: 1696 MB
Dedicated Memory: 64 MB
Shared Memory: 1632 MB
Motherboard: z77 extreme 4 asrock recommended by toms hardware
Powersupply: Silvertstone Srider essentials 500w
Tower: MSI Tc-128
Cpucooler: Hyper 212 EVO COolermaster
Solid state drive: Vertex4 2.5 solid state drive.
Hardrive: Seagate 1 terabyte external hardrive

Im thinking I need a higher psu( like 700w or 600w), if not I dont understand why its shutting off itself like this. Only when I got this card it is doing so.

the 760 tips the ballance of stability against the psu. if it works ok without it (using the internal graphics) it means it's either the graphics card itself or the psu.

500w is more than enough for this card.

Check that the graphics cards fans are running and such. You might also want to grab a program which shows you the graphics card temperatures so you can tell that it isn't simply overheating when you start gaming. While unlikely it is possible that heatsink has come lose of the card and is not working properly because of that even if the fans are spinning. Or there could be something else wrong with the card.

The other option is that the PSU doesn't have enough juice to run the card and as you start gaming the powerdraw increases and the PSU can no longer power the card sufficiently.

XFX Core Pro 550W or 650W will do fine for powering the card, if it indeed turns out the problem is the power supply.

the newer card has a higher voltage draw. also cheap no name power supply under higher voltage load cant hold up.

I would say PSU, Im pretty sure thats a single 12V rail PSU.
I would look into an affordable Seasonic USA PSU that is 520w or higher.
500w is probably enough but not if it can't feed the power consistently under load.

I will agree that the PSU is not the best quality, but it is not terrible by any means. With a system usage of 350w MAX load it should be fine, but a replacement is always an option.

What are some top quality, strong, and long lasting power supply companies?

Corsair, Antec, XFX, Seasonic.
