NVIDIA’s newest graphics card, the RTX 2080 Ti, is designed to be the company’s flagship card.
Expensive and powerful, the card features 11 GB of GDDR6 RAM, AI-enhanced graphics, real-time tracing and up to 6 times the performance of other graphics cards.
Quiet and efficient, this model has memory speeds of 14 Gbps, 4352 NVIDIA CUDA cores and a base block of 1350 MHz, which can be overclocked to 1635 MHz with the founder’s edition.
It’s a graphics card that all top-tier gamers recommend, but being blazing fast also means that the RTX 2080 Ti needs a lot of power. Therefore, you’ll need to think about the best power supply for the RTX 2080 Ti because it demands a minimum of 650W to run.
If you haven’t chosen your RTX 2080 Ti yet then take a look at our best RTX 2080 Ti graphics card guide.
But NVIDIA is stating that they recommend 650W with 250W – 260W needed to run the card by itself.
If you’re running the 2080 Ti, there’s a good chance that you have a very high-end gaming computer as is. Your processor, motherboard, hard drive, memory and peripherals are all going to demand a lot of power already.
Let’s not forget about your cooling setup, too, which may be drawing a lot of power from the power supply. The GPU’s temperature can max out around 89C, so you’re going to want to test the internal temperature of your rig to adjust your cooling as needed.

Adding in the 2080 Ti will make the demand for power even higher.
What’s the Best Power Supply for the RTX 2080 Ti?
You’ll need to eliminate any bottlenecks in your current computer setup to really leverage the power of this graphics card, and you’ll need some of the best components available to do this. With that said, you’ll want the following:
- 750W power supply for a single card setup
- 1000W power supply for running 2 x RTX 2080 Ti in SLI

Sure, the card may run fine on the 650W, but peak power may spike and demand may be higher. You always want a little clearance or wiggle room with your PSU, so going to 750W or higher is recommended.
And the price difference between the 650W and 750W is negligible.
I wouldn’t recommend going into a cheap or budget PSU either. You want a reliable PSU that will last for years and not need to be replaced. This rules out purchasing the:
- XFX XT
- EVGA B1
- OCZ Fatality
- Corsair VS Series
- Cooler Master B2 Series
Dozens of low-end power supplies can be ruled out because they’re just not going to offer the reliability that you need. If you’re spending the money on the best graphics card on the market, you may as well go with a platinum-rated power supply.
Platinum and Titanium are the highest rated power supplies, and you may even be able to dip into the gold-rated power supplies. I recommend staying away from the silver, bronze or lower rated graphics cards because they’re not as efficient.
Our Choice for the Best 750W Power Supply for the RTX 2080 Ti Graphics Card
A 750W power supply should have more than enough power for maxing out the 2080 Ti. There are a lot of power supplies to choose from, but I would recommend nothing less than a platinum-rated PSU.
The following three PSUs offer the power and reliability that you need to run the 2080 Ti.
Corsair HX750 Platinum Rating
Corsair’s HX750 is a platinum-rated power supply that’s fully modular and comes with a 10-year warranty. In addition, the PSU features a 135mm fan with a zero RPM mode and is rated at 100,000 MTBF hours.
Virtually silent at low loads, the HX750 will be able to power the 2080 Ti along with the 6th generation of Intel Core processors.
EVGA Supernova 750 P2
EVGA’s Supernova 750 PW is another 750W power supply that is fully modular and also platinum-rated. This model comes with an eco-mode and 10-year warranty as well as a free power on self-tester.
Fan size is 140mm with double ball bearings for smooth, silent operation.
SilverStone Technology 750W
SilverStone Technology’s 750W platinum-rated power supply offers a 100% modular design and has 40C operating temperatures. Ultra-silent, the fan on this PSU is 120mm with intelligent semi-fanless operation for better, quieter operation.
The unit also offers strict 3% voltage regulation and operates on fanless mode up to 20% PSU load.
Best 1000W+ Power Supply for the RTX 2080 Ti
A 1000W power supply is overkill if you’re running just one RTX 2080 Ti, but if you plan to run with an that allows you to run two graphics cards at once, you’ll need a 1000W unit.
EVGA Supernova 1600 T2
The 1600 T2 offers more power than you’ll need for the RTX 2080 Ti, even on the dual, SLI setup. But if you have advanced cooling, you may need the extra boost of power that the 1600W offers. Otherwise, you can downgrade to the 1000W model as you see fit.
The 1600 T2 is crossfire and SLI ready, so it’s designed to work with dual cards.
Fully modular, this PSU comes with a 10-year warranty and offers UVP, OZCP, OPP, SCP and OTP protection. The fan size is 140mm double ball bearing, and the 1600 T2 is titanium certified.
The HX1200i is a 1200W power supply that offers Corsair link integration, fan speed adjustment and rail modes.
In addition, the multi-GPU ready PSU is fully modular, and it is platinum certified with a 10-year warranty.
ZeroRPM mode is offered on lower loads while the 140mm fluid dynamic fans will keep the PSU cool at all times. Optimized for multi-GPU setups, the HX1200i offers the power your 2080Ti needs with top-tier cooling.
Seasonic Prime Ultra 1000 Titanium
Seasonic’s 1000W power supply is another fully modular model, and it comes with a 135mm FDB fan with an additional power on self-tester. This model is backed by a 12-year warranty, and it is titanium-rated.
The fan controls feature a hybrid design for silent operation and SATA 3.3 connectors are available, too.
While these aren’t the only power supplies on the market that can run the 2080 Ti efficiently, all of these models offer top-tier functionality, platinum and titanium ratings, and the power needed to run the most powerful gaming computers.
