What's the best PSU to use for my setup?

I'm currently using a Corsair 620 watt modular PSU, and since i am building a whole new setup, i think it would be a shame not to upgrade this also.
Will update* New specs are : Q6600 quad, evga 780i, OCZ 8GB nVidia, 2X 8800 SSC 640MB SLi, Scythe Infinity 5 heat Pipes CPU Cooler, 4X 500GB 7200.11 Seagates, and my Soundblaster X-Fi sound card.

What brands would you use based on stability, cable management, and
wattage?

I was thinking either:

Thermaltake Toughpower W0131RU 850W ATX 12V V2.2 Quad SLI Ready Power Supply Modular OR
OCZ (OCZ900MXS) ModXStream 900W ATX V2.2 20/24PIN SLI Ready Modular
I need to know by March 6, so any input would be nice

For that PC get the 1200W Thermaltake Toughpower. (400USD i guess).
There are other brands available like PCPC 1200W, but they r insanely priced @ around 600 USD.

I dunno if the 900W will be enuff for that Monster Config so its better to be safe !

Yeah Thermaltake is quicky being my first brand choice but 1200 watts? lol
I guess why not, ehh, better to have a lil more than not enough.
Honestly, you would think a 1000 watt PSU is more than enough, but if I do find a good deal in the next week or so, I'll go for a 1200 watt PSU.
I can't wait for one of my friends to ask, how many watts u got? I'd say 1200 hahaha

Yup ordered the Thermaltake Toughpower 1200W PSU model# W0133RU it's crossfire and nVidia Sli Certified.
Wat a sexy thing...and huge (hope it fits in my case) ...lol
Should be here next Sat...now I can complete my build.

Whats wrong with the CoolerMaster 850w or 1000w or even if you feel the need for that much juice the 1250w.

They come in both fixed and modular models and they are one of the most stable PSU's. They are also running you with 6 x 12v rails and they are running @ the rated power as continuous. The 850w has max output of 1000w and the 1000w and 1250w units have even more gruntl.

All three are nVidia SLi certified and I believe they are the PSU's that nVidia sell from thier own site. I've got the 850w and it's been rock solid for my use.

Cool, let us know how it goes. Only reason I was suggesting to stay clear of the TT PSU's is because of the problems people have been having between them and G92 based 8*** series nVidia cards.

Congrats on your purchase grimreaper !
As Dalork said , let us know how it goes.

Ohh I will for sure...thanx for all your responses

Like I promised , I 'll let you guys know how it went....wow
As you can see I've updated my signature to reflect what I have now as of 03/10/08.
This system is an animal, and I couldn't be happier now, the WEI sub score went to a near perfect 5.9
The PSU is unreal, together with my new evga 780i mobo...this thing has more options than I could ever imagine.
No conflicts with either my 8GB OCZ or the vid card.
Re-installed X64 Vista, had BSOD(only cause there was more than 3GB) this issue never fails, therefore, re-installed with 2GB, then added the other 6GB, and no problems.
Also, this thing it so quiet, you swear it was off
I have a ton of pics if you want to see, so lemme know, and I will gladly post right here.
Thanx for your interests

While buying too much of a power supply isnt bad, (other than the cost) here is a cool utility to aid in knowing roughly how much power you need
