Overview

The Cooler Master V850 SFX Gold (MPY-8501-SFHAGV-EU) is an 850-watt power supply built in the SFX form factor, targeting PC builders who need substantial power delivery in space-constrained cases. With 80+ Gold certification, it operates at high efficiency across a range of loads, minimizing energy waste and the resulting heat — a critical consideration in small form factor builds where airflow is limited and every degree matters.

Designed for demanding hardware configurations, the V850 provides enough wattage to support current high-end GPUs and multi-core processors without running near its limits. Its modular cable management lets builders use only the cables they need, which is especially valuable in SFF enclosures where unused cables have nowhere to hide. While the SFX form factor commands a price premium over standard ATX power supplies and the shorter cable runs may require extensions in larger cases, the V850 SFX Gold is purpose-built for compact systems where full-size units simply do not fit.

Frequently Asked Questions

What form factor is the V850 SFX Gold, and will it fit in ATX cases?

It is an SFX form factor power supply, designed primarily for small form factor (SFF) cases. It can fit in standard ATX cases with an SFX-to-ATX adapter bracket, which is commonly included or sold separately.

Is this power supply fully modular?

The V850 SFX Gold is designed with a modular cable system, allowing you to connect only the cables your build requires and reduce clutter in compact enclosures.

What does the 80+ Gold certification mean for this unit?

It means the power supply operates at 87-90% efficiency under typical loads, wasting less energy as heat. This translates to lower electricity costs and reduced heat output inside your case compared to lower-rated units.

Can the V850 SFX Gold handle high-end GPUs?

Yes, 850W provides enough headroom for most high-end graphics cards alongside a modern CPU. Check your specific GPU's recommended PSU wattage to confirm compatibility.
