Power Supply Unit Phanteks Revolt SFX 850 W

The Phanteks Revolt SFX 850W is a compact SFX power supply designed for high-performance small form factor PCs. Built to Intel ATX 3.0 platform specifications, it provides native PCIe Gen5 12VHPWR support and 850 W total power with 80 PLUS Platinum efficiency, reaching approximately 92% efficiency at 50% load. The unit includes a 92 mm Fluid Dynamic Bearing fan with intelligent thermal control and a 0 RPM mode under 30% load for reduced noise. Cable lengths and connector layout are optimized for compact chassis, particularly compatible with Phanteks Evolv Shift XT.

Advantages

The Revolt SFX 850W combines a full 850 W output in a super-compact SFX footprint while meeting ATX 3.0 requirements and offering native PCIe Gen5 12VHPWR compatibility. High efficiency is certified by 80 PLUS Platinum, which helps lower energy losses and heat generation. Tailored cable lengths and a 92 mm FDB fan with 0 RPM operation under light load provide quieter operation and better fit in small chassis.

Suitable for

• Compact gaming and workstation builds using SFX or SFX-L cases
• Systems with next-generation GPUs requiring PCIe Gen5 12VHPWR
• High-performance small form factor PCs where space is limited

How to use

Install the Phanteks Revolt SFX 850W into a compatible SFX or SFX-L power supply bay following your chassis manual. Connect the 18+10 pin ATX motherboard power connector and CPU/GPU power cables as required, ensuring the native 12VHPWR connector is used for compatible GPUs. Verify input voltage range (100–240 V) and secure cable routing to avoid airflow obstruction. When powered, the fan control will manage cooling and switch to 0 RPM mode automatically under light loads.

Recommendations

Use this PSU in small form factor builds where ATX 3.0 compliance and native 12VHPWR support are required. Ensure case compatibility for SFX dimensions and plan cable routing for compact layouts to maintain optimal airflow and cooling.
