When your GPU is pushed to the max your system uses double power if not triple.
try seriously to put some graphic extensive settings down in game and play for a day... and i dont mean turn just shadows 1 notch down..
just try to play with average settings and see what your computer does.. if it still shuts down .. then it's probly time for a better PSU.
And ofcourse if your Graphic card is overclocked.. put those first back to factory settings.

was only playing on high, but went to standard, testing that now. and i would never overclock my card lol, i'm a noob. plus i am monitoring my card since my last one was an overheater, this one purrs through the game on max at 43 degrees, but i'll go standard and try, check in in 15 min

Sounds like your power supply doesn't have the output that it needs. Playing graphically intensive games, demands more from your PSU, so playing those other games doesn't really prove much.

If you're not getting any errors, and your PC is just outright shutting down, it's almost certainly a PSU issue.

yeah, i had a similar problem years ago with my old surepower 410 from thermaltake. she lasted 6 years of hard work.
then started shutting down for no good reason. over time, i reduced the amount of items connected to the PSU and sure enough, it worked for a while but then carried on shutting down. in the end it was just board, hdd and graphics card, i had to disconect everything else.
grabed a new psu and was fine, but then i migrated my sims stuff to a smaller form factor PC my dad got me and now my only problem is too much downloads in my folder can casue my game to slow XD

(not the baby i play my online games on tho, that ones a custom hand built 8core *pats*) so yeah, it sounds like the PSU has started its journey to Silicon Heaven. if you never use the other drives like DVD ect, or other items, try disconecting those, and start saving for a newer PSU, thats how i eeked out the last life of my old thermaltake.

It might help if you gave us specifics on what hardware you have. Also, as others have mentioned, it seems likely to be your power supply. Borrow a friend's, swap them, and see if things change.

If ur machine is cutting on and not cutting back on on its own then its 90% going to be a heating issue. It could be power supply over heating, cpu, gpu, or even the chipset controller on ur motherboard. Def check into these.

And stop buying cheap $25 PSU's ... whether it's 500 or 900W.. it does not make little difference. , just because you own a 750W PSU doesnt mean it will work as intended , gamer PSU's have 12V rails on them with at least 50 ampere output on.
The standard sold cheap PSU's are meant for office and regular use , not gaming systems.

Shops building computers always have the cheapest PSU in the case unless you demand a gaming computer wich are usely 2-3x more expensive due to high quality components in them.

Edited because not correct info :P
Because i used to have dual rail PSU's , but forgot what realy matters is the amp on the 12v Rail

power supply is taking a dump

It's a good chance its your PSU.

When everything is under load your computer probably draws peak wattage of your PSU so 600 Watts. The problem with that is that PSU's technically don't draw 600 Watts from the power socket, they draw a variable amount to supply 600 watts to the computer. So if you're not able to draw enough from the wall socket that could create an influx into your PSU so if your computer needed 590 watts to run under its current load but were only able to get 589 W theoretically from the wall then it would cause a shut down.

I've had the same problem with a 550 W PSU, it wasn't enough. I upgraded to 750-800 W just to be on the safe side. I would suggest replacing your PSU to at least 650, 700 to be safe. Other's may disagree, but that's my opinion based on my own experiences.
