first time build, need psu advise

[intelftw]

Im getting prepared for my first build and like anyone else i want to make sure i have the right parts. Im pretty sure on everything except my power supply. Im going to be running dual SLI cards, an i7, 2 Hdds, 12gb ddr3 ram, and possibly a couple extra fans. Just to be safe i want around 1000W. I have a couple PSUs chosen for my case but im not sure if they are compatible or reliable.

case -- Newegg.com - COOLER MASTER RC-690-KKN1-GP Black SECC/ ABS ATX Mid Tower Computer Case


psu 1 -- Newegg.com - COOLER MASTER Silent Pro Gold Series RSA00-80GAD3-US 1000W ATX 12V v2.3 / EPS 12V v2.92 SLI Ready CrossFire Ready 80 PLUS GOLD Certified Modular Active PFC Power Supply

psu 2 -- Newegg.com - KINGWIN Lazer LZ-1000 1000W Modular 80 PLUS BRONZE Certified Active PFC W/ 3-Way LED Switch and Universal Modular Connector Power Supply


those are the two im looking at, But any other suggested PSUs would be appreciated

i would go with the COOLER MASTER Silent Pro Gold Series as you can be almost certain that it will be quiet,reliable and compatible.

however psu's are not my strongest point so i would wait until you get a few other suggestions first.

hope this has helped

can you be more specific on the parts you're gonna use, like what cards?

my basic question is whether or not the psu is the same type as my case witch is an ATX. both of the ones above are 1000w so they should be fine for powering everything.

Newegg.com - EVGA X58 FTW3 132-GT-E768-TR LGA 1366 Intel X58 SATA 6Gb/s USB 3.0 ATX Intel Motherboard

the hdd are a 150gb 10,000rpm, and a 1TB 7200rpm

if the psu is atx and the case is atx, you should be good.

but, a 1kw psu is just overkill for you. you could get a nice say, 750w, and definitely still be safe.

BTW, if you haven't bought those 450's yet, i'd suggest you dont. for like 20 bucks more you could get a single 6950 which will outperform sli'ed 450's.
