What PSU to buy?

post #1 of 7
Thread Starter 
Hi everyone.
I am building my new entertainment rig. Here are the specs:
AMD Athlon II x3 450 @3.20Ghz
Corsair DDR3 2x2GB@1333mhz
ASUS M4N75TD SLI motherboard
2x XFX 8800GS Alpha dog edition
1x WD 80Gb (windows)
2x WD Caviar Black 320Gb in RAID0 (games, movies, music etc...)
1x Lite-on lightscribe DVDRW+DL rom
1x LG DVD-rom
1x Encore 150N PCI wireless card

Now I want to know what PSU should I buy. I am thinking of going with a Coolermaster. But how much watts should I go for minimum? I am also thinking of OC-ing my CPU and GPU. Will 550W be enough?

My question is why you don't just get 1 640GB HDD?
But yeah, 600 watts looks like it will run that smoothly. (Preferred: Antec or Corsair)

RAID0 has better read performance. So I will have faster loading games, video etc... (bulk data)
So ditch the coolermaster and go for a Antec or Corsair 600 watts

Yeah, but what will you do when (not "if", WHEN) one of those HDD's fails and you have to re-format the other HDD, reinstall Windows and the games? If you are going to get those two I would recommend RAID 1 for reliability. I would only use RAID 0 for short term use (I.E. record setting)

Thats why I installed windows on the single 80GB. If one of the drives fails I wouldn't worry about the games, video and music. It would be just a reason to buy a new drive (or two) and install new games etc...

Btw a drive failure percentage is 5% and with raid0 that is more like 7% in three (3) years. In three years I don't think I will still be using this same rig :S
