PSU Issue or??

Hi guys, i'm currently facing this issue while playing AC4 Black Flag.

Mobo + CPU: Asus P7H55D-M Pro + i5 650 3.2Ghz
GPU: Powercolor HD6970 2GB
RAM: Team Elite Dual CPU 1333Mhz CL9(4 x 2GB)
PSU: Seasonic M12II Bronze 620W

Initially it was running okay on my wireless headphone. Until a few days back when i ran it with my Creative T3(Sharing the same socket as the rig). It suddenly shuts down(No signal input). I ran the fan at 40% and on my intake fan at 1800rpm(180mm fan).

So i google and found that it might be due to the lack of power. Switch back to my wireless headphone ytd and apparently ran for a few hours without issue.

Tried again just now with wireless headphone. Apparently, the same thing happen after just a few mins in.

Can it be due to my PSU?

Edit: Seems like if i underclock the GPU abit, it works..

Edit 2: it just happen randomly again when i was just rockboxing my sansa clip+.

You mean your speaker share same 13A socket as your computer? using multi plug?

Even on wireless headphone will power off?

Yup for both question in 1st sentence..

If speaker goes on, wireless headphone is off..

I just tried with the game but set high performance clock to 700mhz max..No issue with speakers on..

But after some consideration, very likely to upgrade the rig..Current rig no issue anywhere else..
