Compact SFX power supply for small builds

The NZXT PS-8G1BB-US is an 850 W SFX unit built for small form factor cases where space is tight. Its compact dimensions let it fit into chassis that cannot accept a standard ATX supply. Fully modular cables mean you connect only what the build needs, reducing clutter in confined interiors. Japanese capacitors rated to 105 °C support long-term reliability under sustained loads.

ATX 3.1 standard with 12V-2x6 connector

The supply meets the ATX 3.1 specification and provides a 600 W 12V-2x6 connector for modern graphics cards. Efficiency is rated 80 PLUS Gold and Cybenetics Platinum, so less energy is wasted as heat across typical load ranges. Input voltage spans 100 to 240 V at 50 or 60 Hz, making it usable worldwide without a voltage switch. Hold-up time and tight voltage regulation help maintain stability during brief power interruptions.

92 mm FDB fan with Zero RPM mode

A 92 mm fluid dynamic bearing fan handles cooling and can stop completely at low loads for silent operation. The Cybenetics A- noise rating indicates quiet performance even when the fan is spinning. Black embossed cables include six SATA connectors on 100 + 100 mm leads and three peripheral connectors on matching leads, simplifying routing in tight spaces. The unit weighs 0.93 kg and measures 125 x 63.5 x 100 mm.

Perguntas sobre este artigo

Should I pick the 850 W SFX model or a higher-wattage unit?

The C850 SFX Gold delivers 850 W in the compact SFX form factor, so it fits small cases while still powering demanding graphics cards through its 600 W 12V-2x6 connector.

What does the 850 W rating mean once the unit is installed?

It means the supply can continuously deliver up to 850 W total system power with 80 PLUS Gold and Cybenetics Platinum efficiency, low ripple, tight voltage regulation and long hold-up time for stable operation.

What does ATX 3.1 actually cap in practice?

ATX 3.1 compliance ensures the PSU meets the latest power-excursion and timing requirements, and the included 600 W 12V-2x6 cable supports PCIe 5.1 graphics cards without adapters.
