Laptop sudden shutdown

[NinjaPenguin]

Hi

I recently bought a samsung 840 evo 120GB. I installed it in my laptop (acer aspire 5750G). Everything was working nice and dandy, I also ordered a hdd bay to put my old hdd in. While i was waiting for the hdd bay i used a 2.5 inch enclosure with usb 3.0, and once again everything was working just fine. I had it running like this for almost two weeks without any problems. Yesterday the hdd bay finally arrived and i installed it with the old hdd and downloaded the latest drivers, but today when i was playing Titanfall the computer shutdown in midgame, I thought the  files may be corrupt so I re downloaded Titanfall, but this time I put it on the ssd. And the same thing happened.

I think it may be that my computer pulls to much power and it just shuts down before anything breaks.

Is that possible?

Btw here is the link for the hdd bay http://www.ebay.com/itm/330990655994?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649

Proper shutdown or simply turn off?

If proper, perhaps battery issues?

It just shuts off, like the screen just turns black. And I don't think it can be the battery as i'm always gaming with the charger plugged in
