RTX 50 Series PSU Wattage: Chart for Every Card (2026)

Most RTX 50 series cards need less PSU wattage than the box suggests, provided the unit is a quality ATX 3.1 supply. NVIDIA's recommended system power runs from 550W for the RTX 5050 and RTX 5060 up to 1000W for the RTX 5090, and every one of those figures assumes a 16-core Ryzen 9 9950X sits next to the card.

Pair the card with a Ryzen 7 or Core Ultra 7 instead and the picture changes by tier. For the 5060 Ti and the 5080, a good unit one step under NVIDIA's figure is enough, and the 5090 joins them only in one narrow ATX 3.1 case. For the 5070 and 5070 Ti, NVIDIA's number is already the right one. The chart below gives every card, our verdict, and the full answer for each.

At a glance

Read the NVIDIA column as insurance sized for the heaviest CPU anyone might pair with the card, not as a measured floor. Read our column as the answer for the build you are putting together. Where the two differ, the gap is almost always the CPU, which is why every verdict above names one.

How we size PSU wattage for an RTX 50 series card

The method takes four steps, and it is the same one behind every verdict in the chart. Step one is the card's board power from the first chart. Step two is the CPU's package power ceiling from the second. Step three adds about 55W for the motherboard, memory, two NVMe drives and a handful of fans. Add the three and you have a worst-case system ceiling, with every part at its limit at once.

Step four is headroom. Size the unit so that ceiling lands at or under about 80% of its rating. Typical gaming draw then sits near half load, which is where a Gold-rated unit is quietest and most efficient. That margin also covers the millisecond spikes every Blackwell card throws above its rating, the behaviour ATX 3.x supplies are specified to absorb.

Two worked examples show how the CPU moves the answer. An RTX 5070 with a Ryzen 7 9800X3D comes to 250W plus 162W plus 55W, about 467W, or 72% of a 650W unit: 650W is enough. Swap in a Core i9-14900K and the ceiling climbs to about 558W, 86% of 650W, which is why that build belongs on 750W. The same sums put an RTX 5080 with a 9800X3D at 77% of a 750W unit, and the same card with a Ryzen 9 9950X at 86%.

The RTX 5090 is the exception to the 80% rule. With a 9800X3D its ceiling is about 792W, 93% of an 850W unit, and only the ATX 3.1 excursion allowance makes that build work. Our 850W versus 1000W call for the RTX 5090 walks through that narrow case. For everyone else, 1000W is the honest floor.

ATX 3.1, 12V-2x6 and the connector each card needs

NVIDIA recommends a PCIe CEM 5.1 compliant supply for every RTX 50 card, which in practice means an ATX 3.1 unit. ATX 3.0 and 3.1 specify the same power excursion envelope, so the newer badge does not buy extra spike tolerance. What ATX 3.1 changed is the plug: the 12V-2x6 connector shortens its sense pins, so a plug that is not fully seated reports itself instead of running full current through a partial contact.

From the RTX 5070 up, the adapter in the box turns two to four 8-pin cables into one plug, adding connection points and a stiff bundle behind the card. A native 12V-2x6 cable removes both. Our native cable versus adapter breakdown for the 5070 Ti covers when the adapter is fine, and the best ATX 3.1 power supplies all ship the cable in the box.

650W tier pick: Seasonic CORE GX-650

Seasonic CORE GX-650 650W Power Supply ATX 3.1 & PCIe 5.1 Ready | 80 Plus Gold Fully Modular 12V-2x6 RTX 5060 Ti AMD RX 9000 Ready OptiSink Design 7 Years Warranty

Specs

Which cards it covers

The RTX 5050, RTX 5060 and RTX 5060 Ti at every CPU tier, and the RTX 5070 beside a Ryzen 5, Ryzen 7, Core Ultra 5 or Core Ultra 7. It ships a native 12V-2x6 cable on a platform Seasonic builds itself. For a 5060 Ti specifically, our best PSU picks for the RTX 5060 Ti rank five units by build type.

Where it loses

Seasonic's CORE line sits below its Focus line, with seven years of warranty against ten. It also has no room for a 5070 Ti. If the budget is tighter, our budget PSUs that are still safe start at the same 650W tier.

750W tier pick: Corsair RM750x ATX 3.1

CORSAIR RM750x ATX 3.1 PCIe 5.1 750W Power Supply – Black | Native 12V-2x6 Connector, Fully Modular, Low-Noise, Cybenetics Gold, NA

Specs

Which cards it covers

A stock RTX 5070 Ti, an RTX 5080 beside a Ryzen 7 or Core Ultra 7 class chip, and an RTX 5070 paired with a Ryzen 9 or Core Ultra 9. The zero-RPM fan keeps it silent through light loads, and it carries ten years of warranty against seven on the 650W pick. Our 750W picks for RTX 5070 builds list four more units at the same wattage.

Where it loses

Under a 5060 or 5060 Ti it is capacity you will never touch. And an RTX 5080 with a 16-core Ryzen 9 or a Core Ultra 9 needs the next tier up, so buy for the CPU you own, not only the card.

850W tier pick: Corsair RM850x ATX 3.1

CORSAIR RM850x ATX 3.1 PCIe 5.1 Ready Fully Modular 850W Power Supply – Low-Noise, Cybenetics Gold Efficiency, Native 12V-2x6 Connector – Black

Specs

Which cards it covers

An RTX 5080 with a Ryzen 9 or Core Ultra 9, an RTX 5070 Ti with a 16-core CPU, an overclock or a planned 5080 upgrade, and the one RTX 5090 build where 850W works: an ATX 3.1 unit beside a Ryzen 7 class chip with one or two drives. It is the same platform as the 750W pick with 100W more on the label.

Where it loses

For an RTX 5070 with a mainstream CPU it buys nothing you will measure. For an RTX 5090 it is the edge of what works, so a 360mm AIO, extra drives or a Ryzen 9 push that build to 1000W.

1000W tier pick: Corsair RM1000x ATX 3.1

CORSAIR RM1000x ATX 3.1 PCIe 5.1 Ready Fully Modular 1000W Power Supply – Low-Noise, Cybenetics Gold Efficiency, Native 12V-2x6 Connector – Black

Specs

Which cards it covers

The RTX 5090 with anything from a Ryzen 7 up to a Ryzen 9 9950X3D, air or AIO cooled, with two to four drives. It is the tier NVIDIA recommends for the card, and the one we would buy for most 5090 builds.

Where it loses

Below the 5090 it is overkill for every card in the chart. And a 5090 beside a Core Ultra 9 285K or an overclocked 9950X3D with a heavy drive and fan load leaves even 1000W thin. That build belongs at 1200W, and our RTX 5090 power supply guide covers the units at that tier.

Bottom line

If you have an RTX 5050, 5060 or 5060 Ti, a quality 550W unit you already own is usually enough, and 650W is the right buy if you are shopping. If you have an RTX 5070 with a mainstream CPU, buy 650W. If you have a 5070 Ti, or a 5080 beside a Ryzen 7 class chip, buy the Corsair RM750x. If your 5080 sits next to a Ryzen 9 or Core Ultra 9, buy 850W. If you have an RTX 5090, buy 1000W unless your parts list matches the narrow 850W case.

Whatever the tier, put the money into the quality of the unit before the number on the label. If your build mixes in a Radeon card, our PSU wattage guide for nine GeForce and Radeon tiers covers both brands, and our guide to choosing a power supply explains how to tell a good platform from a rebadge.
