A standard GTX 950 reference design comes in at a 90W TDP, which means it requires a 6-pin PCIe power connector as the standard PCIe slot is typically rated to only provide 75W. However, we have seen a couple of AIB partners introducing new 75W versions of the GTX 950 to come in under the limit, and as a result remove the 6-pin PCIe connector needed. One of those is MSI, who has introduced two new video cards that can be powered solely by the PCI Express connection. The low-power GeForce GTX 950 graphics boards from MSI follow similar graphics adapters from ASUS and indicate that there are NVIDIA’s GM206-251 GPUs. At this point we might conclude that the ‘251’ nomenclature refers to the specific silicon design which might afford lower power operation.

The two new cards from MSI are the GeForce GTX 950 2GD5T OCV3 and the MSI GeForce GTX 950 2GD5T OCV2 and are based on the GeForce GTX 950 (GM206) in its default configuration: 768 stream processors, 48 texture units, 32 ROPs as well as a 128-bit GDDR5 memory interface. The GPUs of both cards are clocked at 1076 MHz, but can increase their frequencies to 1253 MHz in boost mode. Both graphics adapters are equipped with 2 GB of GDDR5 memory clocked at 6.6 Gbps, a dual-slot cooling system with an aluminum heatsink, one DVI connector, one HDMI 2.0 port and one DisplayPort output. As mentioned above, neither of the boards require additional PCIe power connectors and their TDP does not exceed 75 W.

The two cards differ in their cooling and length. The first one is the GTX 950 2GD5T OCV3 uses a dual fan design and features a longer PCB which is designed to focus on a typical desktop PC. The shorter GTX 950 2GD5T OCV2 uses a single fan and seems to be designed for mini-ITX systems. Thanks to the fact that the GM206 GPU features hardware-accelerated decoding and encoding of H.265 (HEVC) video and fully supports HDCP 2.2 content protection over HDMI 2.0, the OCV2 card could be a fine choice for small form-factor home-theater PCs. 

That being said we have noticed that on the stock photographs that the smaller model eliminates some of the PCI Express pins for an unknown reason, so the exact feature-set is to be confirmed. We have put questions to MSI on this and will update when we have a response. 

Graphics cards based on the GeForce GTX 950 GPUs with lowered power consumption can be used not only to build SFF HTPCs, but also to upgrade cheap desktop systems, which sometimes do not have a spare PCIe power connector inside. Previously NVIDIA’s partners only offered GeForce GTX 750 Ti without auxiliary power connectors, but this adapter is already two years old, and its performance may not enough for modern titles.

Now there are (at least) two graphics cards suppliers who offer GeForce GTX 950 adapters with lowered power consumption, it is likely that other companies will follow them as well. It is unclear whether NVIDIA officially sells GM206 GPUs with low TDP to address the market of entry-level desktops, or companies like ASUS or MSI simply hand-pick GPUs that do not need more than 75 W of power to function properly. In any case, it is evident that such GPUs exist and are in demand enough that the AIB partners want to produce them.

Exact prices and release dates of MSI’s GeForce GTX 950 2GD5T OCV3 and GeForce GTX 950 2GD5T OCV2 graphics cards are unknown. Keeping in mind that the boards are not exclusive products available only from MSI, their prices will hardly be very high and will be near the GTX 950’s MSRP of $159.

Choosing the Best PSU for Nvidia’s GeForce GTX 950 GPU

Learn how to choose a power supply for Nvidia’s GeForce GTX 950 GPU based on power consumption and other factors.

In this article, I’ll go over the things you should consider when choosing a power supply for your computer with an Nvidia GeForce GTX 950 graphics card.

How to Choose a Power Supply for the GTX 950 GPU

The main job of a power supply is to convert the alternating current (AC) from your wall outlet into the direct current (DC) needed by the components inside your computer.

Power Output

An important factor when buying a PSU is the supported wattage.

You will need to add up the power consumption of each computer component to determine the total output power requirements for your power supply.

The peak power consumption of Nvidia’s GeForce GTX 950 GPU is 90 W.

You can estimate your power requirements by using the following chart.

Component Peak Power Usage
GTX 950 GPU 90 W
Top-Tier CPU (e.g., Intel Core i9 13900K) 253 W
Mid-Tier CPU (e.g., Intel Core i5 13600K) 181 W
Motherboard 80 W
Optical Drive 30 W
3.5″ Hard Drive 9 W
M.2 or 2.5″ SSD 9 W
140 mm Case/CPU Fan 6 W
120 mm Case/CPU Fan 6 W
80 mm Case/CPU Fan 3 W

By adding up these numbers, you can estimate peak power usage. Check out the top-tier and mid-tier example builds below.

It’s generally a good idea to add a 100–150 W buffer to your expected usage. This buffer will give you some flexibility in case of miscalculations and will allow you to add more drives, fans, or add-in cards in the future.

In most cases, buying a little more wattage than you need is a safer choice for ensuring system stability.

Don’t forget to account for the additional power required for overclocking if you intend to overclock your CPU or GPU. Overclocking could require roughly an extra 50–100 W, depending on how much you overclock these devices.

Power Efficiency

PSUs with higher efficiency ratings use less energy and produce less heat, improving their reliability and reducing noise.

The 80 PLUS certification program for power supplies helps to promote energy efficiency by indicating its efficiency rating.

Higher efficiency power supplies may have a higher upfront cost. However, they could potentially save you money on electricity in the long run.

Lower wattage PSUs will be more power-efficient even when idle. For this reason, you may be able to save more on electricity by getting the correct wattage of PSU than by getting the one with the best 80 PLUS rating.

PSU Efficiency Levels (115 V)
Certification Level 10% Load 20% Load 50% Load 100% Load
80 Plus 80% 80% 80%
80 Plus Bronze 82% 85% 82%
80 Plus Silver 85% 88% 85%
80 Plus Gold 87% 90% 87%
80 Plus Platinum 90% 92% 89%
80 Plus Titanium 90% 92% 94% 90%



Make sure your PSU has the correct connectors to support the hardware in your system. Cheaper PSUs may cut costs on connectors and cables by offering fewer options and shorter lengths.

Check with your motherboard and graphics card documentation to determine which connector types are needed. Buy a popular, recently-released PSU; it will likely have the necessary connectors for a new PC build. However, if you use old components or an old power supply, you may find some incompatibilities.

Here are some common connector types that power supplies support:

  • 24-pin connector for the motherboard
  • 4/8-pin connector for the CPU
  • 6/8/16-pin connectors for graphics cards
  • SATA Power connector for each SATA HDD or SDD storage device

The latest graphics cards and ATX 3.0 PSUs support a new 16-pin PCIe 5.0 connector that replaces multiple 8-pin connectors.

Modular Cables

Typical power supplies come with various cables to connect your components. However, extra unused power cables can work against you by interrupting airflow.

In comparison, modular and semi-modular power supplies allow for attaching only the cables you need. As the name implies, semi-modular power supplies have some wires soldered on, while you can optionally connect others.

Cable Lengths

Most power supplies will have cables long enough to support mid-sized towers comfortably. If you have a full-size tower, you may want to check reviews and documentation to ensure that the cables are long enough to allow good cable management.

Power Supply Form Factors

Various form factors are available for power supplies. However, a standard-size desktop PC build will use an ATX power supply.

Small form factor PSUs allow for usage in many computer case shapes, including mini-PCs.

Power Supply Features

Overvoltage protection and short circuit protection can help to save your components in the case of a surge or accident.

LED lighting is another feature you might consider, depending on your PC goals.

Choosing a Cost-Effective Power Supply for the GTX 950

Perhaps you live in a dorm or a family member’s house and don’t pay the power bill. Or maybe you don’t expect the computer to have heavy daily usage. In those cases, the lower upfront cost of a less efficient PSU may be the better choice.

On the other hand, if you care more about the electric bill or the environment and plan to maintain higher CPU or GPU usage, then a more efficient PSU may be better.

Don’t go too far over 150 W above your expected power needs. Rightsizing your power supply will keep electricity costs to a minimum, as higher wattage PSUs will consume some additional power, even when idle.
