Best PSU for GeForce RTX 4070 Ti SUPER

The GeForce RTX 4070 Ti SUPER delivers exceptional 1440p gaming performance and high frame rates at 4K. Compared to the standard RTX 4070 Ti, NVIDIA has equipped the SUPER variant with more cores, doubled the frame buffer to 16GB, and widened the memory bus to 256-bit. This provides major improvements to memory bandwidth, now up to 672 GB/sec. With maxed out settings, high refresh rate gameplay, and next-gen graphics features, this GPU offers an ultimate high-end gaming experience. The TGP of GeForce RTX 4070 Ti SUPER is 285W, so you need at least 700W PSU for RTX 4070 Ti SUPER builds. Below are top recommended PSUs for GeForce RTX 4070 Ti SUPER:

Corsair RM850x (2021)

The refreshed RM850x delivers an excellent combination of performance, features and quiet operation thanks to its semi-passive mode. This fully-modular PSU boasts 80+ Gold efficiency and ample 850W capacity with rock-solid electrical performance thanks to a high-quality internal design.

It has two 8-pin PCIe power connectors ready for the latest high-end GPUs. The shift to a tri-fan axial fan layout improves cooling over the older dual-fan RM850x. It’s also tuned to stay in silent, zero-RPM mode up to about 430W load. So you can expect near-silent running during lighter gaming and desktop work.

While not as fancy as some premium PSUs, the RM850x focuses on nailing the basics. It’s a simple, reliable pick that will handle even an overclocked RTX 4070 Ti SUPER with stability and quiet operation for under $150. Just note that it’s fairly large at 160mm depth, so check case compatibility.

NZXT C850 (2022)

The NZXT C850 offers increased efficiency and stable power delivery for high-end graphics cards like the newly released GeForce RTX 4070 Ti SUPER. With 80 Plus Gold certification and an improved design, it achieves over 90% efficiency at 50% load, outperforming the certification’s standard by 2%. This results in less excess heat and lower electricity bills.

As a fully modular PSU, the C850 enables a tidy build by eliminating unnecessary fixed cables. The included black sleeved cables and matte black finish allow the unit to seamlessly integrate into any system, whether on display or tucked away.

Built and tested to NZXT’s strict standards, the C850 guarantees compatibility and trouble-free installation for most ATX cases. It fully supports the latest NVIDIA 3000 and AMD 6000 series GPUs. The advanced microcontroller monitoring provides precise power delivery and comprehensive protection against errors.

Finally, optimizations like quality components and an efficient circuit layout significantly reduce noise production. With upgrades specifically targeting thermal output, the C850 runs cool and quiet even under heavy graphics loads. For stable, efficient power to unlock the RTX 4070 Ti SUPER’s full performance – the NZXT C850 delivers.

Corsair RM850x SHIFT Fully Modular ATX Power Supply

The Corsair RM850x SHIFT offers top-tier quality and performance to support the power-hungry GeForce RTX 4070 Ti SUPER graphics card. Compliant with the latest ATX 3.0 standard, this 850W PSU handles the PCIe Gen 5 platform while resisting transient power spikes that can damage components. The fully modular cables utilize CORSAIR’s micro-fit connectors, allowing you to only plug in the cables needed for a tidy build that enhances airflow.

When demand is low, the cooling fan shuts off entirely for silent running thanks to Zero RPM Fan mode. The RM850x SHIFT employs premium 105°C-rated Japanese electrolytic capacitors that enable stable power delivery and impressive long-term reliability. For systems drawing below 100W, Modern Standby compatibility kicks in for swift wake times and increased efficiency at low loads. With rock-solid electrical performance backed by a 10-year warranty, the technologically-advanced RM850x SHIFT has the cutting-edge specs required to unleash the full potential of the mighty RTX 4070 Ti SUPER.

Corsair SF750 Platinum SFX PSU

The only small form factor option on our list, the SF750, is an excellent choice for compact, mini-ITX builds. Despite its tiny 125mm x 100mm x 63.5mm size, it boasts 80+ Platinum efficiency and can still deliver 750W, meeting Nvidia’s recommended 750W PSU requirement.

It manages solid performance in a tiny package thanks to premium internal components like 100% Japanese capacitors and an 92mm sleeve bearing fan optimized for airflow instead of noise. This makes the SF750 a great pairing for the 4070 Ti SUPER in a mini-ITX case where space is at a premium. Just make sure your case can fit the SFX form factor.

The only downside is that the SF750 is highly popular and often sold out or overpriced currently. But if you can get your hands on one at a reasonable $150 MSRP, it’s the obvious pick for small, power-hungry builds. Expect cooler, quieter operation and a simpler build thanks to the fully modular design.

MSI MPG A850G PCIE 5.0 & ATX 3.0 Ready PSU

MSI’s high-end MPG A850G power supply flaunts compliance with the latest ATX 3.0 and PCIe Gen 5 standards for maximum future-proofing. That overengineered capacity ensures it will easily sustain an RTX 4070 Ti SUPER build for years.

It’s ready for next-gen GPU and motherboard power delivery thanks to its 12VHPWR connector. And it delivers 80+ Gold efficiency with 850W capacity and modular cabling like our other top options. The hydraulic dynamic bearing 140mm fan optimizes airflow through the compact 150mm long chassis quietly even under heavy loads.

While most overbuilt for current systems, features like the built-in RGB light ring, OLED power display and MSI Center software integration might appeal for those creating an all-MSI ecosystem. And the 10-year warranty provides peace of mind. Just expect to pay a high $210 MSRP for those future-looking capabilities.

Conclusion

Ultimately, the Corsair RM850x stands out as the best value PSU that ticks all boxes for the RTX 4070 Ti SUPER without overspending. It offers ample wattage and solid electrical performance wrapped in a compact, quiet package.

The NZXT C850 also deserves strong consideration however if you prefer its modern styling, RGB lighting and low noise profile. But you can’t go wrong picking between those two excellent 80+ Gold units with 10-year warranties.

Any of these PSUs can readily power a 4070 Ti SUPER build. Just make sure to account for case compatibility given their different sizes. And if aesthetics matter, consider the unique looking Shift Edition RM850x or MSI’s high-tech RGB model. Whichever you choose, use this guide to make sure your PSU won’t hold back your next high-end GPU upgrade.
