Overview

This fully modular SFX power supply delivers 850 watts through a single +12V rail. It includes a native 12VHPWR connector for modern GPUs and meets Intel SFX 12V V4.0 standards.

Compact SFX Design

The unit fits the standard SFX form factor at 100 mm deep. A fully modular layout with flat array cables keeps small builds clean and improves airflow inside tight cases.

Performance and Cooling

A single +12V rail provides the full 850 W for high-end CPUs and GPUs. The 92 mm fluid dynamic bearing fan stops at low loads and runs quietly under stress, backed by Japanese capacitors for long-term stability.

Modern Connectivity

Includes one 16-pin 12VHPWR connector compliant with PCIe 5.0 and Intel SFX 12V V4.0, plus two 6+2-pin PCIe, one 4+4-pin CPU, four SATA, and three 4-pin Molex connectors.

Protection Features

Built-in safeguards cover over current, over power, over voltage, under voltage, short circuit, and over temperature conditions to protect connected components.
