I am building a complete sys but am unsure what PSU wattage will suffice.

*Phenom II X2 555 Black. 80w stock (if the unlock/overclock gods are with me, x4/3.6-3.7Ghz)
*GeForce GTX 260 896MB 448-bit (6/6+2 pin) - min 500w PSU required.
*2 x 4GB DDR3 1333's
*CORSAIR CWCH50-1 H20 CPU cooler (will be adding later on with an extra 120mm fan for push/pull)
*Sentey case w/ 4x120mm's. 3 are LED.

I have been building and learning for the past 2 weeks solid and will be placing my order tonight @ midnight and am sorta stuck on what will suffice me for PSU.

I thought about just calling it quits with this 1000w PSU for $109 out the door, but some of the bad reviews scare me to DEATH:

Things like frying MoBo's, RAM, GPU's, Drives, sparks, smoke and melting wires is NOT cool.
RMA costs money to ship back (loss of $$ that COULD be invested).

Thank you.

[edit] Also 80 plus certified is a good thing right?

You won't need anything over 650W with your system (1000W is overkill, plus the Rosewill would probably be the death of your system any ways). I would highly recommend going with the Corsair CMPSU-650HX at a price range of $104.99 after MIR. It is one of the best 650W PSU you can purchase and has more than enough juice for your system.

are there any pro's or cons to 1 & 4 rails?

@ tecmo: THAT is a beautiful PSU, man! Exactly what I'm looking for - BUT the rebate time limit has me debating.

@Davcon: Antec unfortunatly is OUT. Too many DOA's in the reviews for me. Sad because I have the first modular made too (Antec NEO480 - and it's STILL thumpin, man!) SeaSonic has some good looking stuff. But I am not sold just yet.

Plus to you all, I am kinda looking to invest into something I can keep around for a while.

I ended up going with this PSU:
due to money restrictions and the fact that a builder I know sayd the last 20 antec 650's he's bought for builds HALF have been DOA. and commented on how the 620's were a much superior product and wondered if they changed suppliers for parts when they went to the 650's and 750's.

So this is what I am settling for @ the moment.

Also ran accross a great deal on DDR3 1600's at the last minute also:
CORSAIR Vengeance 8GB (2 x 4GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800)
$144.99 on sale for $84.99!!!

Thanks guys for your help. PEACE!

I am actually going to end up going with this 9.5 rated PSU:
The Antec High Current Gamer Series HCG-900 900W ATX12V v2.3 / EPS12V v2.91 SLI Certified CrossFire Certified 80 PLUS BRONZE Certified Active PFC Power Supply

I have decided to go with such a high wattage for 2 reasons:
the 5 year warranty plus it will allow for future planning for a power source for later on, because if things are going to stay the same as they are and have been, i will need this higher PSU in a few years anyway.
