The Inq is showing off some various booths at CeBit including the Thermaltake booth.  They were showing off LED lightbulbs, a new CPU heatsink and a new HTPC case, but the most interesting is the 2 kW power supply that is shown powering TWO complete systems including a Quad-CrossFire system and an SLI system.  I don’t think we could have demonstrated the “overkill factor” any better myself.

Thermaltake 2000W PSU

If you didn’t gather from the picture above, that is one PSU powering two high end multi-GPU systems at once, QuadFire on top, SLI on the bottom. Should your next system require 6 GPUs and 2 mobos, Thermaltake has the PSU for you.
