Default Recommend a PSU for me please

Hello guys
my PC shuts down under heavy load (Gaming) but there's no overheating issues with me .i stressed my CPU and its fine but my GPU Stress test doesn't complete it shuts down the PC

I tried valley benchmark again and i monitored it with MSI Afterburner the benchmark draw 100% power of the GPU and it was fine but somewhere in the benchmark it draw 84% power then it happened again now i'm confused is it the GPU or PSU?. and there wasn't any overheating max 75 degree

I'm doubting my PSU here.

I can play some games that doesn't take much resources from my GPU and PSU like League of Legends, Dota 2, And some Assassin's Creed games without any problem and the PC runs normally but in case of high end games that requires more power from the GPU and PSU it shuts down.

one more thing when the PC shuts down it goes back up again all on its on and i hear a weird noise like a blower before it goes up again.

Specs
Cpu: INTEL Core i7 4770K
Cpu Cooler: Corsar 100i hydro series
Motherboard: Gigabyte G.1 Sniper 5
GPU: Nvidia GTX 780
PSU: Corsair CX750
SSd Adata XPG 910


BTW the PSU's available here in my country
FSP HYDRO G 750W (i want to buy this one)
seasonic m12ii 750w evo edition
cooler master v750 semi-modular (overpriced in my country)

i need recommendation on this list.
Thanks in advance.

That PSU should be plenty. Is anything overclocked? Do you have a log of the crash dump?

A high-end 450W PSU is more then enough, but the PSU can be broken.

I think the Seasonic is the best out of those choices but I'm no PSU guru. I would do some more troubleshooting first before you buy a new PSU though.

EDIT: Hmm actually I just checked out the review for the FSP and it looks pretty good as well and is more modern and more efficient so that's probably the better choice.

You sure? You already have an old graphics card? SLI with a GTX 780 really isn't something you should do. SLI is actually only needed and interesting with a 4K screen.

Yeah by time you plan to SLI you can just buy a GTX 1070 or 1170 depending on what time it is and be much better off than buying some old, used GPU of someone's off Ebay.
