How big of a psu will a need

Hey all I am slowly adding new things to my pc so i know i need a bigger PSU

My specs are

- Asus m2n32 Sli Deluxe mobo
- Amd 6000+ x2 cpu
- 2gb Corsair ddr 2 pc6400c4 ram (2 x 1gig stiks)
- 2 x Sata DVD
- 1 x Sata HDD
- 2 x IDE hdd
- XFX 8800GT XXX EDITION 512meg Core Clock 670Mhz
- Asus Arctic Square cpu cooler (unless someone knows a better one for that cpu)

+ I am getting a new case that will have a lot of fans with a Cold Cathode or 2 ....

So how big of a PSU would I need for that and a good solid working one as well. I heard Thermaltake are not that good for PSU's..

Thx in advance,...

that should do it for ya it runs mine flawlessly

 

650 Wats, will do you well, but you might want 750 to allow for expandibility. The only thing thats really sucking power is your 8800.

The above powersupply is allright, save the fact that it has 3 12v rails. I recomend going single rail.

Here's a 610 wat single rail psu

PSU Calulator

This can accurately determine what wattage you need, I suggest adding at least 100w to the answer to allow for upgrades.

 

As far as brands...Antec I would say is the top dog.

I have always used Ultra cause of the price and never had a problem. But I also have a comp that has been running a super generic 400w PSU for about 4 yrs without a hickup, but I always walk on eggshells when I enter the room!!

You will typically find that most people base their opinions on personal experience.

So is it better going single rail? A lot of PSU's I look have multiple 12v rails so I thought it would be better getting one with multiple...

 

hope this helps,

never saw that back to class for me

 

Ok thanx for the replies i am slightly getting confused lol. I understand that multiple rails are not any better then single rails but a majority of psu's come with multiple rails now it is harder to find single rail psu's.
I am an aussie and the main store I get my pc gear from is http://www.gamedude.com.au What would be a good psu from them...
I know I am contradicting myself here but I like the thermaltake toughpower 750w PSU. That should be alright should it not.??

I am also kinda looking at a PSU with a bit of good looks about it like the Mirror finish. Not like the Corsaid PSU's they are just ugly..

 

And another website I go through is http://www.pccasegear.com. Any thoughts??
