The Best Power Supplies for the RTX 4060 Ti
Five 550W to 750W units for the RTX 4060 Ti, which NVIDIA pairs with 550W, chosen with a later card upgrade in mind.
By The PC Journal editorial team
12 min read5 products evaluated
NVIDIA recommends a 550W power supply for the RTX 4060 Ti. Most versions use one 8-pin plug, but some partner cards use a 16-pin connector, so check your card before choosing cables.
We compared wattage, connectors and ratings from the power supply listings against NVIDIA's guidance; we did not load-test these units.

Best Match for an RTX 4060 Ti1 of 5
MONTECH Century II 550W on Amazon (opens in a new tab)
Montech's Century II 550W is a fully modular 80 Plus Gold unit with a native 12V-2x6 cable and a 10-year warranty, unusual at this wattage.
Best for
- Builds that will keep this card.
Skip if
- Skip it if rated output matters most to you; the SAMA GT750 offers 750W.
Why we like it
Its 135mm FDB fan has a zero RPM mode, and it uses 100% Japanese capacitors. The silver metallic finish is MONTECH's signature look. It is ATX 3.1 and PCIe 5.1 ready with a 12V-2x6 cable.
On rated output it trails the group at 550W, while the SAMA GT750 offers 750W. It also offers a 135mm fan that can stop at low load. The MONTECH Century II 550W comes with a native 12V-2x6 cable, so a 16-pin card plugs in without an adapter.
No depth is rated for the MONTECH Century II 550W, so check the maker's page against your case's PSU bay. Its price falls between the SAMA GT750 and the be quiet! Pure Power 12 750W, based on our last check.

Best Compact 750W5 of 5
darkFlash DG750 on Amazon (opens in a new tab)
darkFlash's DG750 is a 140mm-deep 80 Plus Gold unit with a native 12V-2x6 cable and a hydraulic-bearing fan.
Best for
- Short PSU bays.
Skip if
- Pass on it if a shorter 5-year warrant rules it out for your setup.
Why we like it
Its warranty is 5 years. It is fully modular with a quiet HDB fan, 80 Plus Gold rated, and backed by a 5-year limited warranty. Its fully modular cables reduce clutter for first-time builders.
It matches the SAMA GT750 and the be quiet! Pure Power 12 750W on rated output (750W). It also comes with a 140mm body that leaves room for cables. The darkFlash DG750 comes with a native 12V-2x6 cable, so a 16-pin card plugs in without an adapter.
At 140mm deep, compare it with your case's PSU clearance before buying. No other pick here cost less at our last price check, and the SAMA GT750 was closest. Native 12V-2x6 cable count is its weakest area, and the MONTECH Century II 550W covers it better at 1.

How We Chose
Each pick was assessed across 4 criteria weighted for real-world use.
- Price
- We grouped picks by price at the time of writing.
- Connectors
- We recorded native 12V-2x6 cables and PCIe 8-pin connectors where the listing states them.
- Wattage
- We compared rated output with NVIDIA's or AMD's recommended system power for the card.
- Build and warranty
- We checked depth, modular cabling, fan-stop modes and warranty length.
What to Look for in a PSUs for RTX 4060 Ti
Key buying criteria so you get the right fit the first time.
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.
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.
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.
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.
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.
Check depth and cabling
Deeper units can clash with drive cages or front radiators. Fully modular cables make routing easier in tight cases.

Frequently Asked Questions
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 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.
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.
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.
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.
Bottom Line
Montech's Century II 550W is enough for an RTX 4060 Ti and carries a 10-year warranty. If you plan a bigger card later, SAMA's GT750 or darkFlash's DG750 add headroom at a small premium.
