12 min read5 products evaluated

NVIDIA recommends a 550W power supply for the RTX 4060 and RTX 4060 Ti. Most versions use a single 8-pin plug, so check the connector on your card.

We compared wattage, connectors and ratings from the power supply listings against the card maker's guidance; we did not load-test these units.

How We Chose

Each pick was assessed across 4 criteria weighted for real-world use.

Build and warranty
We checked depth, modular cabling, fan-stop modes and warranty length.
Connectors
We recorded native 12V-2x6 cables and PCIe 8-pin connectors where the listing states them.
Standards
We noted ATX version, 80 Plus and Cybenetics ratings.
Wattage
We compared rated output with NVIDIA's or AMD's recommended system power for the card.

What to Look for in a PSUs for RTX 4060

Key buying criteria so you get the right fit the first time.

  1. Start from the card maker's PSU figure

    NVIDIA and AMD publish a recommended total system power for each card, and partner cards often state their own. Treat that figure as the floor, then add headroom for a high-power CPU.

    More wattage than you need does not harm anything; it mostly costs money.

  2. Use the warranty as a quality signal

    Long warranties of seven to twelve years show how long a maker expects a unit to last. A power supply often moves from one build to the next, so the warranty matters.

  3. Match the power connector

    Most RTX 40 and RTX 50 cards use a single 16-pin 12V-2x6 (12VHPWR) plug, while many Radeon cards use two or three 8-pin plugs. A native cable avoids bulky adapters.

    Push the 16-pin plug fully home and avoid a sharp bend right at the connector.

  4. Check depth and cabling

    Deeper units can clash with drive cages or front radiators. Fully modular cables make routing easier in tight cases.

  5. Compare efficiency ratings

    80 Plus and Cybenetics ratings describe how much power turns into heat. Gold is the usual target for a gaming PC; Platinum and Titanium run cooler and cost more.

  6. Prefer ATX 3.1

    ATX 3.1 units are designed for the brief power spikes modern graphics cards produce and ship with the revised 12V-2x6 connector. Older units can still work, but check the maker's guidance for your card.

Frequently Asked Questions

Can I use the 16-pin adapter that came with my graphics card?

Yes, if it is the maker's own adapter and every 8-pin plug on it is connected. A native 12V-2x6 cable is tidier and has fewer joins.

How much headroom should I leave above the recommended wattage?

The card maker's figure already covers a typical system. Add 100 to 150W if you run a high-power CPU or plan a bigger card later.

Is an ATX 3.0 power supply still fine?

Generally yes. ATX 3.1 mainly revises the connector to 12V-2x6 and relaxes some spike requirements; check your unit's cable is rated for your card.

Can I use an SFX power supply?

Yes, if the case supports SFX and the unit meets the wattage and connector needs of your card. SFX units cost more per watt.

Can I reuse the power supply from my old PC?

Only if it meets the card's wattage and connector needs and is still under warranty or in good health. Very old units lack modern connectors.

Does a Platinum unit save much on electricity?

Only a little for most gaming PCs. The main gains are less heat and often a quieter fan.

Bottom Line

Montech's Century II 550W is the best-matched unit for an RTX 4060, with a 10-year warranty. Its 650W sibling leaves room for a later upgrade, and SAMA's GT650 White suits light builds.
