So I have had my motherboard and system set up for about a year and a half no issues. I saved up some money and bought my self a water cooling kit and installed that. The first two boots were successful (however i plugged in the basics to the plugs in the back, keyboard, mouse, and monitor), just to see if it will boot up. I ran prime 95 and the temps were lower so i thought every thing was great. However when I plugged all my cords and booted the computer, my computer made a noise and popped then I started smelling smoke . I then investigated and noticed my motherboard and the place where the MOSFET was located was fried.

So, Any reasons why?
Maybe the mother board wasn't strong enough to handle the rig?
MAybe the PSU wasn't strong enough?
Anyways just trying to crack down why the motherboard would fry like that, so any help would be great!

Specs:
Gigabyte 990FXA-UD3 MotherBoard
AMD FX 8320
Cooler Master Seidan 120v (Water Cooling)
8 Gigs of Ballistix Ram
Nvidia Reference Card 560ti x2 (SLI)
120 SSD
500 GBs x2
650 watts power supply

Yeah for sure. That HCG is a good PSU. Much better by miles than the Corsair. Make sure if and when you get the card back to check the BIOS version and if it's not the most recent one available to update it. They'll probably update it while they have it if it's repairable or if they send a replacement it's usually been updated already, but make sure. According to the board description it needs the most recent version to address some multi-card issues.
I notice you don't indicate the brand or model of the PSU. At the risk of being wrong I'm going to assume this is because it's either been repurposed from an older build or it's an off brand PSU. Chances are real good that your PSU took out your motherboard. That's why we tell people that the PSU is the most important component in the system and nomatter what else you skimp on, don't skimp on that.

And if your PSU wasn't strong enough you might have issues like crashes and bsod or other issues but being too weak probably wouldn't fry your board. It might fry your PSU though. Being too weak AND being cheap, that could fry your board. Here is some good info on the importance of the PSU and the Tom's tier list of PSU's. You want something on Tier 3 or higher. Preferably on tier 1, 2a or 2b. Model is just as important as brand. There are many brands that have good and bad models of PSU.

I figure its my psu too, however mines a corsair tx 650 watt power supply. I wouldn't see that as the issue. Is there a way I maybe overloaded something??

Well, that's a tier 2A PSU, so it's not a cheap or poorly designed PSU. Which doesn't mean it can't still be bad.

Is there any chance at all that the liquid cooling loop leaked? Did or have you noticed any coolant at all?

Maybe it was just the un-luck of the draw and you got a motherboard with a problem. I'd still completely test the PSU before I connected it to another motherboard and took the chance on frying it. Here's a good tutorial on testing if you are unfamiliar with the procedures.

I didn't see a leak however, prior to plugging my system in i used the compressed air can to blow the dust away, is it possible for dust to cause this issue??
 
I wouldn't think so. I guess anything is possible but in the realm of what could be the old adage "If my aunt had a #@$% she'd be my uncle" comes to mind. So no, it's HIGHLY doubtful. Unless by can of air you mean half air half water. Heh. Or, if the air was coming out at like three hundred PSI, that might cause an issue. A power surge, moisture, bad motherboard, bad PSU or another component with a short causing a high current draw are the likely causes. GPU?

lol Maybe, just maybe, it could be the GPU. Once I get my motherboard back from the RMA i'll be sure to test my components. I think I'll be swapping the PSU to Antec HCG M 620watts and go without SLI, just to be on the safe side. Thanks for the help.... Now lets hope this issue didn't take out my cpu or any other parts...
