How to Choose a Power Supply for the RTX 3060 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 RTX 3060 GPU is 170 W.

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

ComponentPeak Power Usage
RTX 3060 GPU170 W
Top-Tier CPU (e.g., Intel Core i9 13900K)253 W
Mid-Tier CPU (e.g., Intel Core i5 13600K)181 W
Motherboard80 W
Optical Drive30 W
3.5" Hard Drive9 W
M.2 or 2.5" SSD9 W
140 mm Case/CPU Fan6 W
120 mm Case/CPU Fan6 W
80 mm Case/CPU Fan3 W

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

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 can also save you money on electricity in the long run. I've experienced firsthand that utilizing a PSU with a high 80 PLUS efficiency rating can significantly reduce energy usage, heat production, and power costs, depending on your usage patterns.

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.

Cables

Connectors

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. In my experience building computers, I have discovered the inconvenience of power supplies with short cable lengths. Short power cables can pose a massive challenge when reaching the necessary components, making case layouts look cluttered and obstructing airflow.

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 save your components in the case of a surge or accident. I've experienced multi-component failures before and would prefer a PSU with these protective features to avoid buying a whole replacement system when the cause is preventable.

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

Choosing a Cost-Effective Power Supply for the RTX 3060

You may live in a dorm or a family member's house and not pay electricity bills. Or you don't expect to use your computer daily for an extended period. In those cases, the lower upfront cost of a less efficient PSU may be the better choice. I once lived in a dorm without having to pay for electricity. With moderate computer usage, I decided to try a less efficient PSU to save on upfront costs. It helped me in that situation.

On the other hand, if you care more about your electric bill or the environment and plan to maintain higher CPU or GPU usage, a more efficient PSU may be better. As I became more conscious of my electric bill and environmental impact, I observed that my high CPU and GPU usage took a toll. So I researched and analyzed my options. Based on my findings, I invested in a more efficient PSU. It was a decision that paid off, as I saw a noticeable decrease in electricity costs over time.

Stay under 150 W above your expected power needs. Rightsizing your power supply will keep electricity costs to a minimum, as higher-wattage PSUs consume additional power, even when idle. I've experienced a situation where I chose a PSU that exceeded my power needs by a significant margin. Unfortunately, I learned the costly way that when my computer was idle, the high-wattage PSU consumed unnecessary additional power. This experience made me realize the importance of rightsizing my power supply to keep electricity costs to a minimum.

I've come to understand the significance of considering my specific circ*mstances and needs when choosing a PSU. Whether it's about saving costs or reducing my environmental footprint, making an informed decision is beneficial in the long run.
