The best power supplies for your GeForce RTX 50 series graphics card from ROG and TUF Gaming

Friends don’t let friends buy bad power supplies. The PSU is the unsung hero of your system, cleaning incoming power from the wall and providing it as needed to each of your PC components, all at precisely the right voltages. And if you're upgrading to one of NVIDIA's latest GeForce RTX 50 series GPUs, you might need to upgrade your PSU as well. It's critical to get a quality power supply, but shopping for one can get complicated quickly, so let's break it down a bit.

We offer a few distinct lines of products when it comes to PC power supplies, each with its own look and feature set:

• The ROG Strix Platinum line of power supplies offers high performance in an accessible package, with qualiy components like GaN MOSFETs and our GPU-First intelligent voltage stabilizer. A distinct style tops off the design, ready to stand out in any build.
• The ROG Thor collection of power supplies offers our highest wattages with the best efficiency, thanks to GaN MOSFETS and other high-end components. A GPU-FIRST intelligent voltage stabilizer provides ultra-stable power for high-end builds, while a small OLED display on the side shows your PC’s power draw.
• The ROG Loki is, as its name suggests, a smaller brother to the Thor line, providing Platinum efficiency in an SFX-L size for small form factor Mini-ITX builds.
• The ASUS TUF Gaming Gold power supplies offer efficient, dependable power for builds of all stripes, built to withstand extreme temperatures, vibration, corrosion, and more, engineered to power your rig (or rigs) for years to come.

You can read more detailed descriptions of these power supply families here. However, even within those distinct lines of products, you’ll need to narrow down your options. Here’s everything to consider when shopping for a power supply.

How much power do you need?

Before you choose a power supply, you need to narrow down your power requirements. ASUS and ROG offer options from 750 watts with all the way up to 1600 watts with the ROG Thor 1600W Titanium III. If you aren’t sure what your next machine will require, we have an interactive power supply calculator that suggests the wattage you’ll need based on your build. You can also refer to this handy table for NVIDIA and AMD GPUs, past and present, that will give you the required wattage of your CPU and GPU.

However, we often recommend choosing a power supply at least one level higher than required, since the extra overhead will help if you add lots of USB devices, plan on overclocking your system, or want to set yourself up for the future — a good power supply can last you multiple builds, and our ROG and TUF Gaming power supplies come with a 10-year warranty so you can buy with confidence for the long haul.

• If you’re cranking performance to the max with the new GeForce RTX 5090, we recommend one of our top-tier ATX 3.1 power supplies like the ROG Thor 1200W Platinum III. Its premium components provide stable power to your entire PC, while our patented GPU-First patented Intelligent Voltage Stabilizer (IVS) ensure your GPU gets the power it needs even during intense loads.
• If you're gunning for the new GeForce RTX 5080, you’ll want a high-end power supply like the ROG Thor 1000W Platinum III, which contains all the same features of its more powerful sibling. The ROG Strix 1000W Platinum also makes a good pairing with the GeForce RTX 5080.
• For the GeForce RTX 5070 Ti, we'd look at the ROG Strix 850W Platinum, which offers the same high-end components and efficiency as the 1000W version, but at a slightly lower wattage. We also recommend the TUF Gaming 850W Gold if you want a more straightforward option.
• The GeForce RTX 5070 has similar power requirements to the 5070 Ti, so check out the ROG Strix 850W Platinum, TUF Gaming 850W Gold, or ASUS Prime 850W Gold.

Waste not, want not: Choose your efficiency level 

The recommendations above will get you where you want to go, but if you want to learn more about what all those terms mean, we've got you covered. The max power rating, or max wattage, is a great way to understand the capabilities of a power supply, but you should also consider a PSU's efficiency rating. When a power supply draws electricity from the wall, some is necessarily lost in conversion for your components. The higher a power supply's efficiency, the better it is at turning a watt of power from the wall into a watt of power for your PC, which means a lower power bill, less heat, and less noise. Less efficient power supplies might have a cheaper up-front cost, but you end up paying for more electricity that never makes it to your gaming machine and instead gets lost as waste heat.

Fortunately, all current ROG and TUF Gaming power supplies are 80 Plus Gold rated or higher, meaning that when running at 50% load, they can turn 90% of the AC power from the wall into DC power for your computer. More premium power supplies like the ROG Strix 1200W Platinum and the Thor 1600W Titanium III bump up the efficiency even further, offering the very best in modern PSU technology.

And remember, those efficiency ratings are just the minimum required to receive that label. The ROG Thor 1200W Platinum III, as you can see from the graph above, exceeds the 80 Plus Platinum requirements for even more efficient power. This is thanks in large part to premium components like our GaN MOSTFETs, which provide more optimized power delivery to all your components — and since they’re so small, they allow for a simplified internal layout for better heat dissipation.

And of course, our top-end power supplies also come with our new patented GPU-First patented Intelligent Voltage Stabilizer (IVS) as well. Modern high-performance graphics cards often require quick bursts of power during intense gaming sessions, and by tracking the GPU’s voltage needs, ROG Thor III and ROG Strix Platinum power supplies can adapt their power delivery more quickly to ensure stable, optimal performance, even if your graphics card is overclocked.

Easy cable management: Modular and etched cables

Many power supplies come with all the cables attached to the main unit, which means you can just plug them in and go — but they can also create a bit of cable clutter inside your machine. All ROG and TUF Gaming Gold power supplies are modular, meaning they allow you to disconnect the cables you don't use for a cleaner look. Don't have any SATA devices? No problem, just leave those cables in the box and save yourself the hassle of cable management right from the very beginning.

In addition, our current crop of power supply uses etched instead of traditional sleeved cables. Made from a premium pliable material, these cables are more flexible during installation, and operate at temperatures 50° C lower than the safety limit when routed for cable management.

In addition, many current-gen graphics cards use the brand new 12VHPWR standard. The current generation of ROG and TUF Gaming units come with dedicated 12V-2x6 cables included, meaning you won’t need a separate adapter for your new graphics card. Our upgraded PCIe connectors use high-performance copper pins for improved power delivery efficiency and cooler operation for long-term stability.

Treat yourself to a little something extra 

Our ROG power supplies wouldn’t live up to the name if they didn’t include some of our signature features. Our Thor PSUs, for example, has received a Lambda A+ Certification for low noise operation, emitting less than 20dB during operation. In addition, our Thor power supplies feature their own small OLED display that lets you keep an eye on power usage, no monitoring software required. On the latest Thor III units, this OLED display is magnetically detachable, and can be moved to either side of the PSU — so whether it’s mounted fan up or fan down, you can keep an eye on your system.

The latest Thor and Strix power supplies also support Aura Sync RGB lighting, allowing you to you easily coordinate the RGB illumination of your PSU with the rest of your rig.

We’ve also built an incredible cooling solution for all our ROG power supplies, with additional heatsinks installed that are not required for normal operation. This means that even in some gaming loads, the fan won’t need to activate to dissipate its heat, giving you truly silent operation. When needed, that 135mm Axial-tech can spin slower to keep itself whisper quiet at all times. 

Finally, while black works with most builds, some builders like to opt for a white theme to lighten up their system. With that in mind, we developed white editions for a few of our power supplies, like the ROG Strix 1000W Platinum White Edition. Built with the same high-end components, but coated in white and paired with matching white full modular cables, your build will never look the same.

No matter which power supply you choose, you can feel confident that your system will receive reliable, stable power for whatever components you’ve packed into your gaming PC. Check out our full line of power supplies here to find the right one for you.
