The Best Power Supplies for the RTX 4070 Ti and Ti Super
Six 750W and 850W units with native 12V-2x6 cables for the RTX 4070 Ti and Ti Super, which NVIDIA pairs with 700W.
By Alex Morgan, PC Hardware Editor
12 min read6 products evaluated
NVIDIA recommends a 700W power supply for the RTX 4070 Ti and RTX 4070 Ti Super. Both use a 16-pin connector, so a 750W unit with a native 12V-2x6 cable suits either.
We compared wattage, connectors and ratings from the power supply listings against the card maker's guidance; we did not load-test these units.

Our Picks
Best Match for an RTX 4070 Ti1 of 6
be quiet! Pure Power 13 M 750W
be quiet!'s Pure Power 13 M 750W offers four PCIe 8-pin connectors plus a native 12V-2x6, and its fan switches off at low load.
Best for
- Most RTX 4070 Ti builds.
Skip if
- Skip it if you need to know its warranty before buying; the maker doesn't publish one.
Why we like it
Cybenetics rates it Platinum. Its fan stops completely at low load, and one strong 12V rail handles GPU power spikes. LLC topology gives tight voltage regulation.
It is 80 Plus Gold with up to 94.3% efficiency and an ATX 3.1 design with a native 12V-2x6 connector. All 750W sit on a single 12V rail, which handles short GPU power spikes. It matches the SAMA GT750, the be quiet! Pure Power 12 750W, the LIAN LI SP750 V2 and the MSI MAG A750GL PCIE5 on rated output (750W). No depth is rated for the be quiet! Pure Power 13 M 750W, so check the maker's page against your case's PSU bay.

Best Budget Pick2 of 6
SAMA GT750
SAMA's GT750 uses Japanese capacitors with an LLC and DC-DC design, a native 12V-2x6 cable and an ECO silent mode for low loads.
Best for
- Keeping cost down.
Skip if
- Its warranty is not published, which rules it out if you need that number.
Why we like it
Its ECO silent mode keeps the 120mm FDB fan quiet at low load, and Japanese capacitors with LLC and DC-DC topology support long-term stability. Embossed modular cables are easier to route. Its embossed modular cables improve airflow and make routing simpler.
On rated output it ties with the be quiet! Pure Power 13 M 750W, the be quiet! Pure Power 12 750W, the LIAN LI SP750 V2 and the MSI MAG A750GL PCIE5 at 750W. The SAMA GT750 comes with a native 12V-2x6 cable, so a 16-pin card plugs in without an adapter. No depth is rated for the SAMA GT750, so check the maker's page against your case's PSU bay. It undercut the Rosewill VMG 850W and every other pick on price at the time of writing.

Best be quiet! Value3 of 6
be quiet! Pure Power 12 750W
be quiet!'s Pure Power 12 750W pairs a native 12V-2x6 with three PCIe 8-pin connectors, cooled by a temperature-controlled 120mm fan.
Best for
- Quiet builds.
Skip if
- Its warranty is not published, which rules it out if you need that number.
Why we like it
Its airflow-optimised fan blades reduce turbulence, which helps keep it quiet under a gaming load. It suits a mid-range build that still uses an 8-pin graphics card, and be quiet! designs it to handle short power excursions from the GPU. On rated output it ties with the be quiet! Pure Power 13 M 750W, the SAMA GT750, the LIAN LI SP750 V2 and the MSI MAG A750GL PCIE5 at 750W.
No depth is rated for the be quiet! Pure Power 12 750W, so check the maker's page against your case's PSU bay. On price it sat third of 6, between the cheaper Rosewill VMG 850W and the pricier be quiet! Pure Power 13 M 750W, at the time of writing.

Best SFX Pick4 of 6
LIAN LI SP750 V2
Lian Li's SP750 V2 is an SFX unit with a two-tone 12V-2x6 cable that shows whether the plug is fully seated.
Best for
- Small form factor builds.
Skip if
- Price-first buyers should look at the SAMA GT750, which cost less when we checked.
Why we like it
It has a 10-year warranty. A 92mm FDB fan keeps it quiet, and its upgraded 3A standby rail helps USB devices while the PC sleeps. Lian Li backs it with 10-year hardware protection.
On rated output it ties with the be quiet! Pure Power 13 M 750W, the SAMA GT750, the be quiet! Pure Power 12 750W and the MSI MAG A750GL PCIE5 at 750W. It matches the MSI MAG A750GL PCIE5 on warranty (10 years). The LIAN LI SP750 V2 comes with a native 12V-2x6 cable, so a 16-pin card plugs in without an adapter.
No depth is rated for the LIAN LI SP750 V2, so check the maker's page against your case's PSU bay. It was the highest-priced of the 6 picks at the time of writing, so the case for it rests on what it adds over the MSI MAG A750GL PCIE5 and the rest.

Best 850W Headroom6 of 6
Rosewill VMG 850W
Rosewill's VMG 850W offers a native 12V-2x6 cable and support for large GPU power spikes, on a fully modular 80 Plus Gold design.
Best for
- High-power CPUs.
Skip if
- Choose another pick if you can't accept this: a shorter 5-year warranty.
Why we like it
Its compact 140mm-deep chassis is 35% smaller than a standard ATX unit, which helps in small cases. Six protections guard against overcurrent, overpower, overtemperature, overvoltage, short circuit and undervoltage. Its steel shell has large vents, and a 120mm FDB fan handles cooling.
It lists ATX 3.0 and 3.1 support, a 12V-2x6 cable and a 120mm FDB fan. Its 850W rated output is the highest here; the be quiet! Pure Power 13 M 750W comes next at 750W. Its 5 years warranty is the shortest in this group; the LIAN LI SP750 V2 leads at 10 years.
The Rosewill VMG 850W comes with a native 12V-2x6 cable, so a 16-pin card plugs in without an adapter. No depth is rated for the Rosewill VMG 850W, so check the maker's page against your case's PSU bay. On price it sat second of 6, between the cheaper SAMA GT750 and the pricier be quiet!

How We Chose
Alex Morgan compared the manufacturer specifications, connectivity, warranty terms and compatibility of every pick. Figures come from the makers unless a third-party source is named; we did not test these products ourselves.
- How these picks were ranked
- We lined up six power supplies on rated output, native 12V-2x6 cable count, 8-pin PCIe connector count and warranty, using each maker's published specs. These are research figures, not bench results: 4 of 6 picks leave out 8-pin PCIe connector count.
- The shared baseline
- All 6, from the be quiet! Pure Power 13 M 750W to the Rosewill VMG 850W, state rated output, native 12V-2x6 cable count and form factor and share Black colour.
- Where the specs have gaps
- The SAMA GT750, the LIAN LI SP750 V2, the MSI MAG A750GL PCIE5 and the Rosewill VMG 850W give no 8-pin PCIe connector count; the be quiet! Pure Power 13 M 750W, the SAMA GT750 and the be quiet! Pure Power 12 750W give no warranty.
- Price range
- At our last check the picks ran from the SAMA GT750 ($50 to $100) to the LIAN LI SP750 V2 ($100 to $150).
