Over at AFOX (an uknown manufacturer active in Asia) they launched unveiled a new AMD Radeon HD 6850 1 GB graphics card that actually has a a single-slot design and get this, it relies 100% on the PCI Express slot for its power.
The AF6850-1024D5S1 from AFOX features a red PCB, a black single slot cooler that covers all of the board's obverse side, and looks to feature a dense heatsink to which air is circulated by a blower.
The card clocks in at a 775 MHz core and 4000 MHz GDDR5 effective memory.
Now the math is simple, a 6850 is rated by AMD to have 127W typical max power draw and the PCIe bus delivers a theoretical maximum of 75W. That slot can push a little more, but that's way beyond specs alright. Well, spotted in Japan, the card is priced at 19,780 Yen, which converts to US $245.
