i also understood that the 38 amps was for the whole configuration and im probably not pull half that they were with a highend mobo and an i7. well i say half but thats over exageration

unfortunately its the one i have in it since i bought it from ibuypower which i will never do again just at the time i didnt know much and im slowly learning more and more. and using the coonix was only a temporary thing until i bought a new power supply. which would be till thursday this week.
I have read that Jonny Guru rates that power supply as quite good. It really surprised him alot. VERRY tight voltage regulation, handles more load than rated, keeps going strong even when hot. Actual maker of that PSU is Superflower. If I were you, I would start there. You could also go with Corsair. Most Corsairs are made by Seasonic. Either of these would keep your whole system running nice and smooth. I am running an AMD PHII 965 BE at 4.2 G with an ATI HD4850 on a Corsair GS800 (I paid $139 at a best but) Runs without a hickup!
Personally, I would steer clear of Roswill PSUs. In general they are not very good. Though that particular one seemed to do decent on JohnnyGururs tests, it still wouldn't sway me.
Instead, Id look towards something like these:
Newegg.com - CORSAIR Professional Series HX650 650W ATX12V v2.2 / EPS12V 2.91 SLI Ready 80 PLUS BRONZE Certified Modular Active PFC Power Supply
Newegg.com - SeaSonic X Series X650 Gold ((SS-650KM Active PFC F3)) 650W ATX12V V2.3/EPS 12V V2.91 SLI Ready CrossFire Ready 80 PLUS GOLD Certified Full Modular Active PFC Power Supply
They are 650 Watt, but thats far more than enough for any single GPU system. And the Seasonic can even run many SLI/Crossfire set ups. The Corsair probablly can as well.
You really do not need 750W or higher unless you are going to be running high end dual GPUS. In which case, a high quality 750W will be plenty, maybe 850.
For any single GPU system, 550-650 is far more than enough power.
Good luck on everything :)
Wish I could rep you but it says i must spread some more around. I agree 750w is a bit over kill and is not needed unless running a sli setup like you just said. Nvdia recommends "Minimum of a 550 Watt power supply, (Minimum recommended power supply with +12 Volt current rating of 38 Amps.)"
well i plan on another gtx 680 soon. running 3 monitors i want two soon 750 is what im really pushing for. but i think i may go with guru the hx just seems too much and im really not crazy for modular
The specs on the Rosewill seem nice enough. It would be more than you'd need for a single (reference) GTX680.
Unfortunately, NVidia's list of SLI certified PSUs hasn't been updated recently:

I'd want something heavier than a good 750W unit for use with two 680s, but 62A may be enough (5A of headroom or so, if the CPU is overclocked).
Buy once, cry once. Spend the money on a good 650W 80+ BRONZE or better PSU for a single GPU system. For a dual GPU system, step up to a 750-800w. No, you probably don't need every watt of power they put out, but you also don't want to be in a situation where you need 700W and only have 650W available. Seasonic is a really good brand because they make quite a few PSU's for other big name companies(look at the Seasonic X750 Gold and look at the Corsair AX series). Antec and Corsair sell reliable ones as well. I used to use PC Power & Cooling PSU's, but they since changed owners and I'm not sure how they hold up anymore.
I picked up the Seasonic X750 Gold while it was on sale for $119 and it is a very well built unit. Full modular, which I wasn't sold on completely until I unboxed it, and more than enough clean power to run whatever I want. Power supplies are one of the components where you buy it and forget it. Buy a good brand, with the connectors you need and rated more than what you need and don't worry about it.....simple as that.
noone is going to say to you the psu will be fine when you have clearly stated the psu is below spec.
I would get a new psu with a single rail or as low rails as possible meaning its less likely your 12v rail will be underpowered.
also make sure it has enough pci-e connectors.
my psu is single rail and I see would only barely be enough at 40 watts which in tturh probably isnt enough as it powers other things as well.
You really need for safety at least a 60 watts rail in my view.
