Triplex Designs Radeon HD 4830 Without Auxiliary Power Connector
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.

To add a point, my case doesn't fit a 4870 well (but I'm making it work for now), I wouldn't mind a couple small 4830's or possibly the 4750's when they come out.
Also, my e-peen is larger than my sensibility concerning this stuff... somehow I'd feel better about having 3 x 4750's vs a 4890. Cuz I'd have 3 :D
@Jizzler: That's a good point about the 4830 having a short PCB. I think it might even be shorter than my 8600gts's pcb. It is good to be able to fit a crysis-capable rig in a grandma-capable tower :roll:
oh yeah I forgot to mention... I am happy to see SOMEONE has taken the initiave and has started moving towards energy efficency with graphics cards. I believe that no computer should have to have a power supply greater than 500w (400-450w max load) unless it's something like a ridiculous fileserver with 10TB of storage space or some crunching workhouse with dual quad-core processors and 64gb RAM
PCI-E x16 2.0: 150w, 8000MB/s bandwidth
^^according to wikipedia
What most people are worried about is that running this 4830 in a 1.1 slot (75w) would be pushing the envelope. I wouldn't do it.
O course, I got both cards for ~150$, so it was worth it. Kinda wish they would make this a Low-Profile card to compete with the LP 9600GT... AMD has nothing in that area...
I use a 7300GS with a AMD 3800 x2 and handles all internet based films and such without issue even HD.
