A relatively unknown company, Triplex, has designed a Radeon HD 4830 graphics accelerator that does not require the 6-pin PCI-Express power connector. This is especially interesting for two reasons: that it is RV770, and that it runs at reference clock speeds despite shedding its traditional power design. Spotted on XtremeSystems, this engineering sample PCB features a 2+1 phase power design, that draws all its power from the PCI-Express slot.
Also featured are 512 MB of 256-bit GDDR3 memory, DVI-D, HDMI and D-Sub outputs, and a seemingly two-slot cooler design that is yet to be pictured. The card lacks CrossFireX fingers. The GPU has 640 stream processors, DirectX 10.1 compliance, and a 256-bit memory interface. It has AMD reference clock speeds of 575/900 MHz (core/memory). For reference the third picture shows a Radeon HD 4670 accelerator of the same make, and PCB length.

The testing above was done with a reference sample HD4830. It used the same PCB design and power circuitry as an HD4850.
The power consumption is just a bit over the amount supplied by the 75W cap. Shedding the complex power circuitry, as Triplex obviously has done, could possibly lower this amount to just under 75W at 3D LOAD. They also might be undervolting it during load, supplying just enough to keep the card stable.
Their HD4830 certainly won't win any OC'ing contests, but should be great for users looking for a low powered card that doesn't need any additional PCI-E connectors...
