EVGA this week unveiled their NVIDIA GeForce GTX 950-based video cards with reduced power consumption. As a result, these new cards do not require auxiliary power connectors and can be powered entirely by a PCIe x16 slots Similar variants have already been announced from companies like ASUS and MSI, but EVGA decided to release a range of such graphics cards as well, including factory-overclocked models.

EVGA’s family of low-power GeForce GTX 950 graphics cards that do not need external power consists of four models, which is a lot by contrast to other manufacturers. The GPUs are based on NVIDIA’s cut-down GM206 graphics die (768 stream processors, 48 texture units, 32 ROPs, 128-bit GDDR5 memory interface) but use EVGA’s custom PCB with 3+1 phase VRM. The GPUs are equipped with 2 GB of GDDR5 memory, one or two DVI connectors depending on model, one HDMI 2.0 port and one DisplayPort output. 

From the four cards, two of them run at NVIDIA’s reference GPU clock rates of 1025/1190 MHz, while the other two a little bit faster and run the graphics chip at 1076/1253 MHz. In each pair, one has a single DVI-I while the other has DVI-I and DVI-D connectors. All the boards feature 6.6 Gbps GDDR5 memory. As for cooling, they use dual-slot single-fan EVGA ACX 2.0 coolers.

Unfortunately, EVGA does not mark its GeForce GTX 950 boards with reduced power consumption with any easy to recognize label, hence, the only way to distinguish the adapters without PCIe connectors is by referencing the product numbers:

While graphics cards like the GeForce GTX 950 are not used to build high-end gaming PCs, these new PCIe-less models can be purchased to upgrade inexpensive or older PCs which sometimes come without an auxiliary PCIe power connector on the power supply. In addition, a GM206-based adapter is a reasonable choice for an HTPC as the GPU supports hardware-accelerated decoding and encoding of H.265 (HEVC) video, as well as HDCP 2.2 content protection over HDMI 2.0 (which is required for Ultra HD Blu-ray playback).

Since at least three manufacturers of NVIDIA graphics cards already offer GeForce GTX 950 boards without auxiliary PCIe power connectors, it is could be assumed that the GM206-251 GPU (revealed by MSI) has been selected due to reduced power requirements. It is unclear whether NVIDIA picks such GPUs itself and then marks them accordingly, or if there is a new revision of the chip and makers of add-in-cards have to test power requirements themselves through binning.

Right now EVGA does not sell its GeForce GTX 950 low power graphics cards on its website. It is unknown at what price these units will be launched at this time.

    its almost like they want me to buy a maxwell card just before pascal drops LOL Reply

    Anton, you may want to explicitly list which part numbers (0952,0954,0956) do not require the 6 pin. I had to go out to EVGA's article to figure it out, as it wasn't real obvious in this piece. Reply

    Well all EVGA skus mentioned in this article are without 6-pin connector(expect 02G-P5-258, which should be 02G-P4-0958 and the table mentions tdp75W thus no 6-pin pcie plug). Reply

    The price, for these cards, in the U.K. is stupidly stupid. Reply
