Does anyone have any experience with the new XG Magnum External 600 PSU? I am definitly interested in this PSU for the fact that its external and it has decent power. But is it powerful enough for a 7900GTX SLI setup?

how were you able to figure that out?

the magnum 600 has dual 12v rails:
12v1 = 18a
12v2 = 22a

Now I don't know whether the 22 amp rail is dedicated to just the graphic cards, but if it is then it should meet NVidias requirements for a high end SLI setup.

nvidia gets their numbe rby adding all ur amps on all ur 12v rails 18 + 22 = 40

You don't even need a 600W..... a 500W would be fine for that..... 2 790GTX's are about 80-90TDP a piece..... so.... plenty of power for that setup.

Thats good news. If anyone else has any other input that would be greatly appreciated.

Would this PSU be able to handle an X1900XTX Crossfire setup? I know the X1900 cards use more power than the 7900 cards, but how much more?

The 1900XTX uses about 120W...... So a good 500-600W PSU could X-Fire two of those cards..... keep in mind they can be loud cards.... due to the stock cooling on some of them.

Thanks again. Any other opinions on this particular PSU and/or the brand XG would be appreciated.

10 amps per card at 12 volts more if you OC them....but one card will give you such high fps that your eyes will never notice if you have a 2nd card or not!

If it was me I would spend half the cost of that 2nd card on a real PSU...PC Power and Cooling 510-ASL (38 amps on 12 volts @ 50C unit temps...not @ 22C as all other PSU are rated).

If I only use a single X1900 XTX card then there really wouldn't be the need for a super high end power supply. I wouldn't compensate with extra hard drives or an FX processor. So in that case I would definitly be able to use this PSU.

The main reason I am interested in this PSU is because I will be using a Lian Li V600 case. The external PSU concept would work out well because then I will be able to use a better CPU cooler and it should decrease the case temp.

I understand that PSUs act as an exhaust for hot air as well, but my V600 has an extra 120mm fan installed on the top of the case to compensate.

XG is a decent brand they have a few decent cases i think the brand it self isnt "great" but its ok, i would go for Antec or something better

XG Magnum Review

As long as you use both rear exhaust fan and the top exhaust fan, you should be fine.
