850W SFX Platinum power supply

This 850W SFX power supply targets small-form-factor builders who need high efficiency in a compact footprint. The 125 x 63.5 x 100 mm size fits SFX cases, while the included bracket allows installation in standard ATX chassis as well. Fully modular cabling and 80 Plus Platinum certification suit enthusiasts who value clean cable routing and low energy waste.

Bundled bracket and switch cable

The SFX-to-ATX bracket extends case compatibility beyond compact builds without requiring a separate purchase. A C14-C13 power cable with an integrated on/off switch lets users cut mains power easily when the unit is hidden inside the chassis. Super-flexible DC cables simplify routing for improved airflow and a tidy interior.

105°C capacitors and smart cooling

All capacitors are Japanese 105°C-rated units, supporting long-term reliability under sustained loads. A 9.2 mm FDB fan remains off below 40% load for silent operation, then ramps up only when thermal demand rises. Active PFC with a power factor above 0.95 and a full protection suite including OCP, OVP, OTP, OPP, SCP, UVP, NLP and SIP guard components during sudden power swings.

商品問答

Will the 12V-2x6 connector power a current-generation graphics card?

The unit provides an 850W single rail with 12V-2x6 connectors compliant with ATX 3.1 and PCIe 5.1, supporting modern GPUs within that power budget.

Does the fanless mode stay off during typical desktop use?

Smart Cooling keeps the 9.2 mm FDB fan stopped below 40% load, so light workloads run silently while the fan engages only under heavier demand.

Can this SFX unit fit in a standard ATX case?

An SFX-to-ATX bracket is included, allowing the 125 x 63.5 x 100 mm chassis to mount securely in mid-tower and full-tower builds.
