Cooler Master V850 White SFX Gold ITX SFF Modular Power Supply

In this review the Cooler Master V850 White SFX Gold is evaluated as a compact, high-output power supply aimed at small-form-factor builders who need serious GPU support. Its single biggest reason to buy is the combination of an SFX mini footprint with ATX 3.1 and a 12VHPWR PCIe 5.1-ready connector that lets it reliably feed modern high-end GPUs while keeping cable clutter to a minimum. For anyone building a mini-ITX gaming PC or workstation and prioritizing efficiency and lasting components, this unit delivers a clear, practical advantage.

Key Features

• Mighty ITX Design: A true SFX form factor that fits mini-ITX and other small cases without sacrificing the full 850W power capacity.
• 90 Durable Cables: The included 12VHPWR PCIe 5.1 connector and reinforced cabling improve electrical durability and safety for modern GPUs.
• ATX 3.1 Support: ATX 3.1 cabling provides up to 600W to the GPU, enabling compatibility with cutting-edge graphics cards.
• 80 Plus Gold Efficiency: Gold-level efficiency reduces waste heat and lowers operating costs compared with lower-tier units.
• Premium Components: 100% Japanese capacitors and a 92mm Fluid Dynamic Bearing fan deliver stable power and quieter, durable cooling.
• Fully Modular: Modular cables help reduce clutter and improve airflow in tight cases, making routing simpler for SFF builds.

Who It's For

The V850 White SFX Gold is best for mini-ITX builders who need high wattage in a small package, such as gamers using high-end GPUs or content creators packing a strong CPU and discrete GPU into an SFF case. Its ATX 3.1 and 12VHPWR support make it particularly relevant for anyone planning to use modern PCIe 5.0/5.1 graphics cards that demand significant single-cable power.

Those who should look elsewhere include users who need extended cable lengths for large, less compact cases or people prioritizing the absolute quietest PSU possible, as noise reports from customers are mixed. Also, builders who prefer inexpensive, non-modular units for basic office systems may find this over-specified for their needs.

Pros & Cons

Pros

• High 850W output in a compact SFX case offers exceptional power density for mini builds.
• ATX 3.1 and 12VHPWR support provide stable, modern GPU power delivery up to 600W via the GPU cable.
• 80 Plus Gold efficiency and Japanese capacitors improve longevity and reduce ripple and heat.
• Fully modular design and customized cable lengths keep SFF interiors tidy and airflow effective.

Cons

• Some customers report variable noise levels and isolated failures, so occasional quality variation is a realistic limitation.
• Cable length may be short for larger cases, and extended cables could be needed if not building strictly SFF.
