PSUs single 12v Rail or more?

In my system I run a 52A 650W Corsair.

It powers:
Q9650 @ 3.6 (400FSB)
4 Dimms of 1066 RAm (8GB @ 4x2GB)
HD 4890 Vapor X (also OCd - 870/1050)
Xtreme Gamer Sound Card
LG BluRay Drive
Intell SSD, OCZ SSD, WD 640GB HD, WD Black 1TB HD
(3) 120mm Fans, (1) 120mm LED fan, (1) 250mm fan
Plus extra USB devices such as Xbox controller etc

It has more than enough power and plenty to spare.



With 9 spinning HD's, I would think the largest drain on the system would be the spinup at startup.


IMHO, the 60A 750W would be more than enough power for that setup.


But I do agree, 1000+ W PSUs are just way overkill unless your doing higher end Tri-SLI or something along that line.

Also, don't skimp on the PSUs. And that doesnt mean get the biggest most expensive one either. Simply, a very good quality built one.

The PSU is probably the 1 single most important piece of Hardware in the system that often gets overlooked.

Well, I went with an Antec True Power Trio 650watt unit.

Quick update .. my GTS 450 OC arrived today and runs perfectly fine on my Antec EA-430D. It runs much quieter and cooler so far. I have not installed the 2nd HDD yet, but I am seriously looking into a 550w or 600w quality PSU when I upgrade my CPU to a AM3 Phenom II X4 something.

Good for you and just make sure it's fully modular to keep the routing clean and to a minimum. I still see a larger PSU in your future. But it's all good !
