Is this PSU able to adequately power my system?

^ Though am not sure how good is that PSU, but theoretically it is powerful enough(actually with some headroom too) for your PC - Has 3x 12V rails +12V1@18A, +12V2@18A, +12V3@15A, so it should be ok,..

But I wouldn't suggest going SLI with that PSU,...

Oh no I never have intentions going SLI, ever.

I would definitely look for a higher quality unit from a more reputable brand with a minimum of 80+ efficiency.

What exactly is wrong with Coolmax? I know you are entitled to your opinions but from my experiance Coolmax has always been amazing in price and stability.

That is interesting a few techies have told me to get a psu with a single 12v rail as well so I did with my previous build which is what killed my other eVGA GeForce 460 GTX, that PSU was an Ultra LSP 650w. To be fair though I think it was a freak accident, the moment I plugged in the two PCIe connectors (power was off and everything unplugged of course) to the card it died right there, fan kept spinning very fast I might add, but no signal.

So That remains a mystery (even stumped eVGA tech support) to this day as to what really happened so I went back to an old favorite PSU.

Ultra aren't what you'd call a 'good' brand tbh anyhows and apart from a short I'm stumped on that card as well,
unless one of the connectors you plugged into it was the cpu block  
I'd say go for a corsair cx500 or similar, about 34A on the 12v but thats enough for you until you go mad on the O/c of course

lol i'm positive it was the two 6-pins. Now I am interested in this single rail and amp thing, heres an example just tell me what would happen.

With the hardware I have there posted but with the coolmax I described, would playing The Witcher 2 be a hassle?

As a side note I don't intend on OCing, it's a personal decision, I just never saw the reason to do it unless for benchmarks and that just seems silly to me.

No thats fine,
I just have to assume the possibility/probability of you overclocking given that you have the 2500k chip so it was more of a headsup for future but I think that set up should be fine, once its built you can check places like http://www.yougamers.com/gameometer/10213/ to see how your system will run W2,
and the single rail thing, if you have multiple 12v rails, you have to spread the overall load to balance current draw so as not to overload the psu, with a single rail, you dont have that concern plus it is stronger overall, I'd take a 70A 12v single rail over one that added up to 92A over three or four lines,
Say Hi to Geralt for me btw, I read one of the books and am trying to find the rest hehe

The problem with Coolmax is the same as with Ultra. They use cheaper components to make a cheaper power supply. Since they are less efficient, they turn more power into heat as well, which is one reason why parts burn out faster.

I've fried power supplies, and I've had bad PSUs fry components. It's a hassle, and it happens far too often. I will NEVER use a cheap PSU again on any of my machines. My latest power supply has gold 80+ efficiency and a 7 year warranty, plus is fully modular. Not only will it keep my gear safe (most likely), but it will literally pay for itself in power savings over that 7 year period.

Your running the Ax850 Jason I believe?
Love that 7 year warranty on those, although 5's enough on the Tx for me, Ordering that and my Mobo monday btw

Just a 750 actually, and nice work on your system! It's looking good so far... I'm a fan of any Corsair PSUs really, even switched to using the CX series ones in my builds for the most part now.

Great, I thought the 7 year was just on the Ax/Hx series, good to know
I've used a few cheaper psu's in builds, but you learn as you go along and the psu in my case is a P.o.s. compared to the Storm 600w I put in my Gf's build, which most people would cry off as a bad psu, but I've had no issues with it, I just figured I was going to invest money in a good system, I wasn't going to risk anything by skimping on a questionable psu, I'm definately a Corsair convert now lol
although I'm going to have to move the rating label and spray the casing Mattblack ofc

It's an AX750
