Cooler Master V850 SFX Gold 850W SFX Power Supply - Compact Power

Our review of the Cooler Master V850 SFX Gold finds it to be a compelling choice for small form factor builders who need high-end, reliable power in a compact package. The single biggest reason to consider this unit is its combination of ATX 3.0 support and a 90-degree 12VHPWR PCIe 5.0 connector that delivers up to 600W to modern GPUs while keeping a small SFX footprint, making it ideal for compact gaming rigs and workstation builds that demand clean, efficient power and a fully modular cable set.

Key Features

• ATX 3.0 Cables: The ATX 3.0 wiring can supply up to 600W to compatible GPUs, giving headroom for current PCIe 5.0 cards without requiring an external adapter.
• 90 12VHPWR Connector: The 90-degree 12VHPWR PCIe 5.0 connector improves electrical durability and reduces strain on the plug, helping protect both cable and connector under load.
• 80 Plus Gold Efficiency: Gold-level efficiency means roughly 90% power transfer from the wall to components, reducing waste heat and lowering operating costs compared with lower-efficiency units.
• Japanese Capacitors: 100% high-quality Japanese capacitors improve long-term reliability and reduce ripple noise for cleaner voltage delivery to sensitive components.
• Enhanced Dissipation: The integrated transformer, rectifier, full-bridge LLC and EMI-inhibited amorphous metal design aid cooling and stable performance under sustained loads.
• Fully Modular and Compact: Fully modular cables and a small SFX form factor keep builds tidy and compatible with a wide range of compact cases.

Who It's For

The V850 SFX Gold is best for enthusiasts building compact gaming systems or small workstations who need ATX 3.0 support and a stout 850W SFX power supply without sacrificing efficiency or longevity. It suits users who plan to pair a modern GPU that draws significant power via the 12VHPWR connector and who value a fully modular cabling layout to minimise clutter.

Those who should look elsewhere include builders with very large cases that require longer-than-stock cables, or quiet-focused users who cannot tolerate any chance of audible fan operation at idle, since customer feedback shows mixed experiences with fan noise and continuous fan behavior in some units.

Pros & Cons

Pros

• Compact SFX design with full 850W capacity makes high-performance small builds possible.
• ATX 3.0 and 90-degree 12VHPWR connector support modern GPUs with up to 600W delivery on the correct cable.
• High-quality Japanese capacitors and 80 Plus Gold efficiency improve long-term stability and reduce waste heat.

Cons

• Cable lengths are intentionally short for compact builds and may be too short for larger cases without extensions.
• Some users report inconsistent fan noise or continuous fan operation under light loads, so absolute silence is not guaranteed.

Our Verdict

The V850 SFX Gold is a strong pick for compact builds that need modern GPU support and reliable, efficient power delivery; its ATX 3.0 compatibility, robust connector design and premium components make it worth the premium for builders who prioritise performance and longevity. Buyers with larger cases or who demand absolute silence should double-check cable reach and consider noise behavior before committing.

Frequently Asked Questions

Will this power supply fit in a small SFF case?
Yes, it is an SFX power supply designed for small form factor cases, and includes an SFX-to-ATX bracket for broader compatibility.

Does the 12VHPWR connector supply enough power for high-end GPUs?
Yes, the ATX 3.0 12VHPWR connector on this unit is rated to deliver up to 600W to compatible GPUs when used as intended.

Are the cables long enough for larger mid-tower cases?
Cables are customised short for compact builds; some larger cases will require extended cables or extensions to reach certain components.
