Im changing my psu because sometimes my computer is dying by itself sometimes it happens around twice a month. I really think its because of my PSU(TT 650w) cant keep up with my GPU(shappire dual-x R9 280x) it says it needs 750w to power. I really need to change it but im not sure what to get since im dont know enough things about PSU.

 

Thinking of getting:

Corsair RM series RM850 80+ Gold fully modular PSU

 

Any recommendations?

Thank you :)

The psu recommendation on the graphics cards' website are highly inflated in case you're using a crap psu. The 280x easily runs off of a decent 550w. Your current psu is more than enough.

If your psu is causing the issue, it wouldn't be because it wasn't big enough.

If you ever need help with a build, read the following before posting: http://linustechtips.com/main/topic/3061-build-plan-thread-recommendations-please-read-before-posting/

Please, with an R9 280x your entire system uses only 350W under load so it's definitely not your PSU

Here you go (No MIR/Promo)

This is why you should not get an FX CPU for ANY scenario other than rendering on a budget http://linustechtips.com/main/topic/286142-fx-8350-r9-290-psu-requirements/?p=3892901 | http://linustechtips.com/main/topic/266481-an-issue-with-people-bashing-the-fx-cpus/?p=3620861

Any suggestions on how to do that?

well i would run prime95 + furmark at the same time. this is way more load than a game can do . so if the pc shuts down run the tests individually and see which cause the problem. if nothing happens run memtest

I ran furmark as furmark and prime95 at the same time about 30mins computer didint crash or shut down. Then i ran furmark for 1hr35mins and nothing happened it was totally stable. My rig seems to be doing pretty well :/ I dont know whats the main cause of this pc just dying out on occasions. Thanks for the help tho :)

I think it could be the power suppily. I like both corsair and if you can pay the price some of the best are made by seasonic. 

Me too i really think its my psu sometimes its failing. when my computer dies out it will take me around 3-5mins before i switch on my PSU or my computer wont boot up
