Aurora R4: GTX 590 ... is SLI possible?
Is this system capable of using the GTX 590, with two cards with SLI?
The power supply is listed as 875W, and I don't know if that's sufficient for two cards.
Dell does not offer two 590 in SLI for a new purchase.
No power supply upgrade options are available for a new purchase.

Nvidia's website says: http://www.geforce.com/Optimize/Guides/how-to-build-a-quad-sli-system
Operating a Quad SLI GTX 590 system requires a power supply that has four 8-pin PCI-Express supplementary power connectors, each of which must receive 150 watts. Because of the complexity of designing, building and ensuring that the power supply meets these necessary requirements, NVIDIA works directly with power supply manufacturers to certify their products for Quad SLI use. The list of power supplies certified for use with a Quad SLI GTX 590 configuration is as follows:
- AcBel PC8055-000G 1100W
- Antec HCP-1200
- Corsair AX1200
- Nexus RX-1.1K Gold
- Silverstone ST1500
- Thermaltake Toughpower W0171 1500
=============
Dell's power supply may be more robust than a 3rd party PSU, but 875W still seems "iffy" for usability.

This seems like a potential add-on option that would boost wattage availability, but which may not modify the system too much or void Dell's repair service plan:
