Server PSU for a gaming rig?

[ScytheSpectre]

A bit of a backstory: So, I've recently built a gaming pc with mid-range specs in the form of an i5-4690k and a gtx 970, and I housed it all in an NZXT Source 210. After a couple of months, I've had to move my pc countless times to the point where it's just plain silly and the sheer size of a case like the Source 210 is the primary reason it's getting on my nerves. I've a bit of metalworking experience and I've always wanted to make my own pc case so I figured this would be the perfect time. That being said, I want it to be as thin and as light as possible and atx power supplies (and even sfx ones) won't fit into my ideal design.

My question is: will this psu http://www.newegg.com/Product/Product.aspx?Item=N82E16817338055 be sufficient for a gaming rig, or should I look elsewhere? It's pretty much the perfect size and shape; I just have no knowledge of this sort of thing.

Firstly, those are LOUD. Like, LOUD LOUD.

Depends on the gaming rig. It's only got one PCIe 6+2 pin connector, and most of the more powerful GPUs use two.

It's also got very tight over-current protection by the looks of it, so molex/SATA adapters likely won't work well.

I'm not sure how decent Athena PSUs are, but the label on that doesn't inspire confidence - no total 12V rail spec, and no literal "700W", plus it's rated at peak power not constant. Price is high, too.

I'd suggest looking elsewhere.
