[Question] Random shut downs at high graphic load

[LukeHimself]

Hello dear community, this is my first post so please be gentle. If I am posting in the wrong board please let me know and / or move my post.

My problem is that my PC shuts down at random times while I play graphic intense games. I got most of my parts in 2013:

Mainboard: MSI P67A-GD53 (B3)
Processor: Intel Core i7 2600k 4x3.40 GHz
RAM: G.Skll 8GB KIT RipJaws-X PC3-12800U DDR3-1600 CL9
HDD: WD Caviar Blue 500GB SATA3 16MB 7200rpm
GPU: Gainward GeForce GTX 570 1280 MB Phantom
PSU: be quiet! Pure Power BQT L7-630W

--------------2015--------------
in 2015 my PSU died and I replaced it with a cheap one from our local tech-shop.
new PSU: Inter-Tech-SL-700-Netzteil-700W

--------------2016--------------
then in 2016 my GPU died so I replaced it with a cheap one to wait for the new 10xx line from that I knew nvidia will release later in 2017 (now)

new PSU: Gigabyte GV-N730D5-2GI GeForce GT730


--------------2017--------------
After getting a job I added 8 GB of ram, same kind as before.
RAM: G.Skll 8GB KIT RipJaws-X PC3-12800U DDR3-1600 CL9 (16GB total now)
I also got a new GPU
new GPU: ZOTAC GeForce GTX 1070 AMP! Edition 8GB GDDR5


-------------THE PROBLEM----------

in 2015-16 before my GPU died I tried playing GTA5 which I think brought my GPU down to its knees.. I could play at about 30 fps on low settings and sometimes my PC would just shut down.
The event manager will just say "system was shutdown unexpectedly" - nothing more...
The same problems with ANNO 2205 which would shut down after playing for 20 minutes.

After my 570 died I stopped playing fancy games and went back to EVE ONLINE (medium settings) and World of Warcraft (medium settings) which worked well on the replacement Geforce 730.. Basicially my PC didn't shut off since the last time I tried playing ANNO 2205 in 2016.

today I got my new 1070 that I've been saving up for and after putting it in, reinstalling all the drivers (clean installation) I turned on WoW (because I had nothing else installed) and turned up the settings to ultra, with full anti-alising and what not... Teleported myself to Stormwind and my PC shut down. I am kind of disappointed by this whole thing. I thought the new generation of cards is supposed to use less power? At the same time I googled that PSU I have in now and it doesn't have the best reviews online...



-------------Questions----------
What do you think about my Problem?
What kind of PSU suits my setup in general now?
Is my PSU the problem?


Thank you so much in advance for reading my wall of text, I really do appreciate every single answer.

Yours Embra

It definitely sounds like the PSU (provided you're comfortable your temps are ok?)..

The "Inter-Tech SL700" is a cheap, poor quality PSU.
It's a "700W" PSU that's only actually capable of ~500W from the 12V rail and carries no 80+ certification of any kind.

The GT730 is a <50W card that you've replaced with a ~150W GPU - paired with your CPU, the 1070 should be able to reach close to it's max performance (and therefor, power draw), adding strain to your PSU.

GTAV brought your PSU to it's knees, not your GPU.

You've now got a setup that could pull ~350W as a theoretical max. A quality 500W PSU would be more than sufficient.

Something like the SeaSonic S12II 520W would be a solid option.

Or the XFX TS 550W

Thank you for your reply Barty1884,

I've ordered a Corsair CP-9020111-DE Vengeance 550M ATX/EPS (https://www.amazon.de/dp/B01CQ4AO3A/ref=pe_386171_147299271_TE_dp_1) because it has good reviews and a 5-year warrancy.

I'll get it tomorrow.

Once it arrives I'll do four things:
1) Replace my old no-name PSU with the new one
2) Check my Tower-Fans to see if the airflow is correct
3) Check the temperatures of my GPU / CPU while playing to see if it's a thermal problem.
4) Post results here.

I can't seem to follow the link you posted, but searching Amazon.de myself, I'm assuming you paid around 65EUR for it?

If that's the case, I would definitely recommend the S12II or XFX TS I linked.

The Corsair Vengeance is ok, it's an improvement over the CX series from the same timeframce.
It's decent enough (and a HUGE improvement over the "Inter-Tech" PSU you're replacing), but it's not of the same quality as, say the SeaSonic S12II.

Review (of the 650W unit).

Thanks Barty 1884,

You're right, I paid around 65 euro for it. It arrived yesterday evening and I tested with great success.

No shutdowns eversince.

Thank you very much!
