Phanteks Revolt 850W SFX PSU at a Glance:

  • SFX PSU ideal for small form factor builds
  • Fully modular design for reduced clutter
  • 92% efficient at 50% load for an 80 Plus Platinum rating

Small and Powerful

A Phanteks Revolt power supply can match the needs of modern components. With many high-performance CPUs requiring over 200W and GPUs reaching 450W+, an 850W supply is highly recommended. With its modular design, the Revolt PSU can support a wide variety of devices including NVIDIA RTX 40 Series GPUs, thanks to its dedicated 12VHPWR output. This new connection can deliver an astounding 600W along a single cable. All power is supplied safely thanks to the many forms of output protection Phanteks has built into the design, including Overpower, Over Voltage, Short Circuit, and Over Temperature protection.

Additionally, the Revolt is a highly efficient power supply, featuring 92% efficiency at 50% load. As such, this PSU achieves an amazing 80 Plus Platinum rating. What’s more, Phanteks has integrated these outstanding capabilities into a small form factor design. Thanks to an included set of tailor-made cables suitable for SFF builds, you’ll be able to build your dream small gaming PC.

ATX 3.0/PCIe Gen5

The Revolt SFX 850W PSU is an ATX 3.0 power supply, which means it has been designed with the latest generations of PC components in mind. Modern hardware requires an ever-increasing amount of power, so the humble power supply has had to be updated to deliver this. As a result, the ATX 3.0 design has evolved to match hardware power demands. Developed by Intel, this new design can deliver reliable high efficacy power, with the Phanteks Revolt capable of delivering up to 600W through a single output. This high-powered output is known as PCIe Gen 5 12VHPWR, and is aimed at safely delivering power to NVIDIA RTX 40 Series GPUs that have been shown to spike in power draws of over 650W. Additionally, this new output features scope for even more powerful GPUs in the future as Intel revealed that PCIe Gen 5 is capable of handling power spikes of up to 1,800W for 100 milliseconds.

Efficient and Quiet Operation

The Phanteks Revolt PSU has been designed to offer outstanding performance and efficiency. Thanks to this, these PSUs can produce exceptional power output with minimal cooling. In fact, the cooling fan won’t even activate until the PSU reaches 30% load for zero noise. Once this load is reached, optimum temperatures can be maintained, thanks to the Revolt’s intelligent temperature control, which carefully balances cooling performance and noise levels. In addition to being whisper quiet, the 92mm fan’s fluid dynamic bearings also reduce vibrations which is ideal for minimising wear and tear. In fact, Phanteks is confident in every component within the Revolt SFX, that they offer an amazing 10-year warranty.

Poor fan curve.

by Muhammed star_border star_border star star star

Specs all seem good but let down by the fan, ramps up and down at idle just sitting on the desktop. I have a watt meter and the pc is only drawing 168w from the wall (13900K + 3090), back to the Corsair SF750 for now until I can find something better.

Great power supply, horrendous cables

by Simon star_border star star star star

If this review was of the power supply alone, it'd be 5 stars. Silent at idle, inaudible from more than an inch away at full load, and compared to other options on the market it is very god value. However, using this thing in any case bigger than a shoe box is practically impossible, because the included cables are incredibly rigid and far too short. I would highly recommend buying some cable extensions unless you are using a a sub-15L SFF case.
