COOLER MASTER V850 SFX 80+ Gold Fully Modular Power Supply (850 W)

The Cooler Master V850 SFX is an 850-watt fully modular power supply built specifically for compact and mini-ITX system builds. Conforming to the SFX 12V Ver. 3.42 standard, it measures just 100 x 125 x 63.5 mm, making it a practical choice for space-constrained cases where a standard ATX unit would not fit. Despite its reduced footprint, the V850 SFX does not compromise on output capability or build quality. Efficiency is rated at 80 PLUS Gold, delivering 90% efficiency at typical load. This keeps heat generation low and reduces wasted energy, which is particularly important in small-chassis systems where thermal management is a challenge. A semi-fanless mode allows the 92mm fluid dynamic bearing (FDB) fan to remain off under light loads, further reducing acoustic output during everyday tasks. The fully modular cable system means only the cables you actually need are connected, reducing clutter and improving airflow inside the chassis. The unit ships with an SFX-to-ATX adapter bracket, allowing it to be installed in standard ATX cases as well, giving builders added flexibility when planning or upgrading a system. Internals use 100% Japanese capacitors as stated by the manufacturer. Protection features cover overvoltage (OVP), overpowering (OPP), short circuit (SCP), overcurrent (OCP), undervoltage (UVP), overtemperature (OTP), and surge and inrush protection. Active PFC (Power Factor Correction) is included, and the unit is ErP 2014 Lot 3 compliant.
