Hey guys, I found an interesting PSU here. Think it'll support a 8800gtx since it's dedicated only to your video cards? Here's the product. http://www.xoxide.com/thermaltake-w099ru-250w-psu.html

Looks like it takes power from the system PSU, so wouldn't that be the same running off the PSU rails?
You talking about the connector that hooks up to the main ATX connection? I looked at the webpage for the product. The wire you see connected to the 24-pin ATX connection is there to sync the power on/off signals for the video cards (So that the video cards and system both start up at the same time).

So currently i have a 500W Ultra PSU, if i get this Add-in that would mean 750W?
Also how would the hook up work say with a 8800GTX? would i hook up both 12A rails to the VGA card and then hook up the extra PSU to the main PSU? becasue 250W alone anit gonna power any DX10 GFX card

250 Watt are more than sufficient. You are forgetting that the mainboard PCIe slot delivers up to 60 Watts too (i´m not 100% on that number, but it does deliver additional Power - how else would a card without 12V Connector be powered.).
To mousemonkey:
As mex mentioned, the connector to the PSU is the power switch. If you connect two regular ATX PSUs and want them to fire up in sync you do it that way too. Check Coolermasters Stacker Case to see a fine example.

It isn't an add-on, but an entirely differnt PSU unit within the system. If you put it in, you would have a 500W PSU to power your main system, and an available (and seperate) 250W PSU dedicated entirely to just the video cards (In addition to the power provided by the PCIe slot.)
Now, this unit would only be good for one 8800GTX, because it is rumored/known to require 2 6-pin PCIe power connections to operate.
And just for the record, I doubt this unit was designed with DX10 cards completely in mind, hence only the 250W figure.

OH nice one Dude, I'm a few beers over the limit and it didn't occur to me to go looking (not sure I could drive the mouse right anyway!) but thanks for clearing that up for me, so am I safe in assuming that it has it's own power feed then? :?

Dude, thank you, :lol: thanks to your link I see the light or rather the power cable going into the rear panel plate. (man I love beer) :lol:

This is what is on my head from everything I have read so far.
1 GF 8800GTX series card will need at least 300 WATTS to run properly. Now most people rumor that 550 Watts is needed at least to run 2 GF 8800GTX in a system. Now thats only for the cards because people always have dvd burners and big hard drives plus high end stuff so you need between 250 watts and 300 watts more to those 550 watts (if you run GF 8800's in SLI) so that makes it a power supply between 800watts and 850 watts. That would be an expensive PSU of 850 watts which we dont see normally and companies are still releasing them in very low quantities and really expensive, but they should suppously run them properly.
Now, this external PSU, I dont think it can run SLI w/ 8800GTX's paired. Maybe 7900GTX in SLI or even 7950GX2 in Quad-SLI but not any GeForce 8800 series because this PSU is limited to a very low watt power (250)
With the last announcement from VR-Zone, that BFG was releasing 1000watt PSU's and 800watt PSU's, I almost sure anything lower than 500 watts will NOT run a single 8800GTX and anything lower than 850watts will NOT run 8800GTX in SLI mode.

if you have a good quality 450watt psu and use this. the o.p. psu
then you would have 700watts(450+the advertised250watts).
so it should work fine. unless you sli 2 g80,s?
then you might need something like an antec tp2 550watt
and the o.p. listed psu?
My current PSU is a 500 watt x-connect modular ultra psu. 12v dual rails and all the good stuff. So, it's pretty much the best 500 watter you can get. Coupled with the 250 watt dedicated 5.25" psu it would probably work fine, right? (Only gonna use one 8800gtx btw 
)

My current system with a e6600, 2 gig ram, 2 320gb hds, 2 dvdrws, 1 floppy, and running a x1900xtx pulled only 180-190 watts during a full load on FEAR. It never hit 200 in the whole time.
I am picking up a GTX when the hit, and am fairly sure my TT truepower 2 500 will power it.
Seems to be some fairly inflated numbers on power requirements, especially a quality power supply versus a cheap one.
The 12 volt rails seem to be the weak link on most budget psu's, and efficiency the second weak link.

Snice this external PSU has dual 12V (PCI-E) rails which are needed on the 8800GTX couldnt the external PSU purely run the 8800GTX(no sli) and maybe get a little more juice from the main PSU. because 50$ for 250 more Watts sounds more reasonable then having to buy a whole new 700W PSU for 150+ dollars
