The PSU is the first place to start. It looks like the PC is dropping when you load the Graphics Card with 3D work. Go into the BIOS and see if there is a section called PC Health. If it is there check the PSU is putting out good steady voltage. Do not run your PC until you confirm the PSU is good or you will blow something in the PC probably your Graphics Card. If the PSU is fine the next port of call is the Graphics Card itself.

Sadly i do not see a pc health section in the BIOS section, what can be done next in distinguishing the issue?

One of the ways Cyberpower (and similar vendors) cut costs so they can sell inexpensive systems is by using garbage PSUs. That would be a good place to start.
Another possibility (which could be related) is that the overclock (I assume there is one, with a water cooler) is unstable.
When you look for a replacement PSU, 500W is certainly enough, but look for full range active PFC (no little voltage switch) and some level of 80+ certification. Antec, Seasonic, Corsair, and Enermax are among the better brands. Older Coolermasters, and Best Buy's house brands (Dynex and Huntkey / Rocketfish) are not.

Currently it isnt overcloked i run it on standard 3.0ghz i dont bother with over clocking, but the issue it the random power outs on it mainly with games and sometimes without a game it will power down, i have a 3 year warranty so im safe to get replacements (of same specs i believe) and i also am within my 30day money back deal so im debating on what should be done.

jtt283 is right in saying that a lot of companys use cheap and nasty PSU's to keep their costs down. If this is the case with your machine then you have to make a choice. If it was me I would take it back and do my own build.

If you're having issues like this while still within a 30day return period, do so. if it's unreliable in the first few weeks I'd hate to depend on it a year from now.
