Hi guys,I have an intel i5 4670k,asus gtx 770 dcu 2,asus z87-k mobo,wd caviar blue 1 tb hdd,corsair vengeance 8gb single channel memory.I have SeaSonic S12II 620 Bronze 620W ATX12V V2.3 / EPS 12V V2.91 80 PLUS BRONZE Certified Active PFC Power Supply.My comp has crashed a few times and i said the asus 5x protection cpu undervolt has been detected and it shuts down my pc.So,is psu not compatable with my processor?should i disable c6 and c7 in my bios?? or go for a "Haswell" certified psu?.Also can upgrade my gpu to gtx 780ti or r9-290/x later with my current psu?.Thanks in advance .

That is the perfect PSU for your system. High quality, and just the right amount of watts/amps for your graphics card. Enjoy!

A few times it crashed due to some asus 5x protection for under voltage was triggered..So,should i disable my c6 and c7 thingys??.Also is psu enough to upgrade my gpu to gtx 780ti or r9-290/x later??
Thnks in advance

Wow, surprised it isn't haswell certified. That is such a great PSU. It will easily power any single graphics card. As for the sleep states, I would disable them to avoid the issues.

Thank you very much 😀.

Sorry to disturb you again.It says c6 and c7 sleep states are supported and i cant do any changes to them...Should i leave it be?

Then we will need to find out what's causing the crashes. I'd say disable it and see if that stops the crashes first. If you still crash, we know that's not the cause.

I am not able to disable it..its kind of blocked 🙁.

Have you noticed a pattern for the timing of the crashes? It might be time to do some troubleshooting. You have such a nice system, it would be frustrating to be crashing all the time.

I live in India and sometimes due to power fluctuations it might crash..and it rarely crashes.
