Oh god. Your rig doesn't require alot of power, and it will work, however its not a great Powersupply.. Right now there is no "good" and "cheap" modular PSU's that I know of.
But this is a better Power supply for less.
If you look, ull see the one I posted be less wattage but you don't need alot of power anyways, It also has dual 12V rails with 18Amps on each while the X-connect only has a single 12V rail and 34amps on it. Therefore we see that the cheaper one has 36 Amps total over 2 rails while the X-connect only has 34, I can also garuntee you that if u buy that X-connect it will feel extremly light, and we all know what that means in regards to PSU's.
(I swear to god Ive reccomended that same PSU like 5 times in last 4 days)
