Best PSU for RTX 4080 Super in brief

1. Corsair RM1000e – Best overall PSU

Form factor

Fully modular

  • Strong pricing
  • Powerful performance
  • Decent build quality
  • Cheaper transistors than X variant

The Corsair RM1000e is our number one pick for the best PSU for RTX 4080 Super and this comes down to its price-to-performance ratio. Armed with the brand’s high quality construction, despite using cheaper transistors than the Japanese ones found in the X-variant, the E-model is considerably more affordable at the $180 mark. It’s fully modular meaning you only need to plug in the cables you actually require which will speed up building and prevent any unnecessarily cable management, too.

We’ve opted for the Corsair RM1000e specifically as opposed to a lower wattage model in order to give you substantial overhead. Nvidia recommends a minimum system power of 750w so you won’t have to worry about any incompatibilities with a full 1000W available. That means a ton of headroom for upgrading in the future and overclocking the components you already own without worry.

2. Be Quiet! Dark Power 13 – Best premium PSU

Form factor

Fully modular

  • Japanese capacitors
  • Silent operation
  • Support for overclocking
  • On the pricey side

If you’re in the market for a truly top-end PSU for the RTX 4080 Super then few options are as coveted as the Be Quiet! Dark Power 13 which is an exceptional 1000W power supply. Armed with leading Japanese capacitors, extensive overclocking options, and a full-mesh front for enhanced airflow, you’ll know this brick is doing its job well but you’ll never hear it in action.

What’s more, the Be Quiet! Dark Power 13 is an ATX 3.0 PSU which comes geared up to handle PCIe 5.0 GPUs out of the box with a dedicated cable meaning you won’t necessarily need an adapter for the RTX 4080 Super here. It also cuts down on the amount of leads you need to run through to the box itself, too. It comes at premium, though, you can expect to pay around the $290 mark at MSRP, but it’s frequently available considerably cheaper with sales common.

3. Cooler Master MWE Gold 850 V2 – Best value PSU

Form factor

Semi-fanless modular

  • Semi-fanless design
  • Aggressive pricing
  • Fully modular
  • Limited overclocking potential
  • Not the most efficent

There’s no reason why a PSU for the RTX 4080 Super has to be too expensive, and that’s where the Cooler Master MWE Gold 850 V2 comes in clutch. It’s available for under $100 and is a fully modular and gold rated 850W PSU that’s ideal for the high-end graphics card. You’ll have headroom of about 100W for any overclocking needs but you won’t be able to crank things as high as with a 1000W model.

There are 2 Eps connectors which mean you should have compatibility with the vast majority of current-generation motherboards which will run with a minimum wattage of 550W and up to the maximum output of 850W. The HDB fan should deliver quiet and consistent performance for reduced noise and cooler running. This new version is also a little more heat resistant than the original model which is now capable of withstanding toasty temperatures of 50 degrees, not that it’ll get that warm unless under heavy stress.
