Power supply selection

[beavermml]

hello to all fellow toms's

i am building my next gaming machine.. this is my current choices so far

what i am going to buy -
intel core i5 2500k
asus p8z68-vpro/gen 3 ( i just want a 6 slots SATA mb.. if there is a better choice out there please tell me )
16 gb ddr3 standard ram
cooler master silencio 550

what will i reused from my old machine
JBOD hard disks of 40GB/80GB/160GB/320GB/320GB/1TB ( i have many documents in these hard disk and it is a pain to relocated them into a new hard disk )
Ati 4870 ( strangely still powerful enough for today gaming.. )

in my list above i am missing PSU.. i convince i cannot used my old one becoz of the problems ( plugging many USB devices will make my internal hard disk disconnected, randomly disconnected hard disk and etc etc )..

currently i am using CM Ex Power Plus 550watt.. which i know is not very good..
in my next build i am interested in Xigmatek NRP-702.. which i dont know is good or not..

i am going to OC my CPU when i have enough money to buy custom cooler.

is there is a better alternative of PSU in the wild that its price is in the range of Xigmatek PSU above? Im tight in budget...
currently in my place they only offer Cooler Master and Xigmatek PSU but if there is another alts i am going to order it online..

That Xigmatek NRP-702 have good reviews http://www.jonnyguru.com/modules.php?name=NDReviews&op=Story5&reid=213
Another good option but non modular is CORSAIR Enthusiast Series TX750 V2 750W http://www.newegg.com/Product/Product.aspx?Item=N82E16817139021 105$ and 95$ after rebates.
If you want something modular then CORSAIR Enthusiast Series TX650M 650W http://www.newegg.com/Product/Product.aspx?Item=N82E16817139031 110$ and 95$ after rebates.
That 650W Corsair is more than enough even for a more powerfull build.

On newegg.com you can get this 750w one for a good deal right now. Was 120, now 85.
