Well as the title states I ordered an open box sapphire 1900xt from newegg along with the VF900. My question is, can my nuuo handle everything in my sig (-7900gt) (+1900xt)? I myself doubt it. Would it be in my best intrests to throw another psu in my stacker (dedicated to 1900xt +some fans or somthing) specificly this http://www.newegg.com/Product/Produc...82E16817182003
thanks for any input!

I think the NUUO can handle it. It's meant for SLI, so I see no problems when it comes to powering your system.

I run my X1900xtx with my Nuuo 550, no problems at all! It should work just fine

X1900 draws up to like 120W (10A) at stock speed, max load. When you OC that baby, it'll draw a bit more , like up to 180W (15), but then you'll have it overclocked a LOT. You should be fine with the NUUO.

Where you get the 250-300W number from??!? I run two of those, that that would mean they'd draw 500-600W... but my 700W PSU handles them with ease (and my Opty draws about 170W at its current clock, and I have four HDD's and all the rest...)

Fill in your specs here. I roughly calculate that your system takes up 377 watts with your x1900xt.

I need to talk with Rusty about that... those seem like numbers for a WHOLE RIG running those cards

Here is some data that confirms my ~120W number
http://www.xbitlabs.com/articles/vid...ion2006_4.html

That 300W is enough for a whole rig with a X1900 does not mean that you can actually use one. A 300W PSU never will have enough current on the 12V rails. You'll need a PSU with roughly 25A-30A at least, and that often means a 500W+ PSU.

Again, your NUUO will be fine

Example rig:
X1900 - 120W
3700+ - 90W
Couple HDD's - 26W
3 120mm fans - 15W
Soundcard - 10W
Optical - 25W
2 sticks RAM - 10W

Total: 296W (add 100W for a nice OC)
