1StPlayer SFX 850W 80+ Gold

Efficiency

80PLUS Gold standard

Thanks to advanced circuit design from 1STPLAYER Labs, the PSU meets the 80PLUS Gold standard and delivers high and stable energy efficiency in everyday scenarios and under sustained loads.

An impressive conversion efficiency of up to 92.3% at typical load (50%) at 115V, which reduces heat loss and power consumption and contributes to a cooler, more economical system—even compared to 230V.

Design and Build

1STPLAYER’s original industrial design language

At the front of the SFX power supply, a large hexagonal heatsink is integrated, responsible for efficient primary heat dissipation to maintain stability even under high loads.

Small triangular vents on the sides of the unit improve airflow and contribute to consistent heat release—a combination that helps optimize temperatures throughout the case.

The fan blades with a gray metal frame, developed specifically by 1STPLAYER, balance performance and aesthetics, creating a “compact and rugged” look in a modern industrial style.

Noise and Cooling

Fan with smart Start/Stop function

The fan offers three cooling modes to achieve the ideal balance between performance, silence, and thermal efficiency; under light conditions it can stop completely for ultra-quiet operation.

Precise thermal management helps reduce unnecessary noise and preserves component lifespan without compromising the stability of power delivery.

Cables and Connectivity

Fully modular system

All cables are modular, allowing a clean and precise installation—connect only what you need while maintaining optimal airflow inside the case.

Cable lengths are designed to fit most ITX cases, with black flat cables and a black modular interface for neat and convenient assembly even in compact systems.

An ideal solution for SFF system builders who want a combination of efficiency, silence, and clean aesthetics—without compromising reliability and performance.
