Compact SFX power supply unit with 80mm fan

BFKK

BFKK SFX 500W Power Supply 80mm Fan 12V 5V 3.3V

SKU CH-435Y-PBQKK

SFX power supply delivering 500W with an 80mm thermal-sensing fan for compact builds

  • TypeMini ITX
  • 500 W steady output powers compact builds
  • 80 mm thermal-sensing fan keeps noise low
  • 5 % voltage tolerance on 12 V, 5 V and 3.3 V rails ensures stability
  • SFX form factor fits Mini ITX and micro ATX cases
  • Multiple cable connectors support a wide range of peripherals

Compact SFX Power for Small Form Factor Builds

The BFKK SFX 500W unit delivers steady 500W output in a Mini ITX footprint designed for compact cases. It suits builders assembling new small form factor systems or replacing an ageing supply in an existing Micro ATX or SFX chassis. The 80mm thermal sensing fan adjusts speed automatically to balance airflow and acoustic levels.

5% Voltage Tolerance Across All Rails

High stability is maintained with a 5% tolerance on the 12V, 5V and 3.3V outputs, protecting sensitive components during load fluctuations. A generous selection of cable connectors is included to support a wide range of peripherals without requiring additional adapters. This simplifies cable routing inside tight enclosures where space is at a premium.

500W Headroom for Versatile Peripheral Loads

The 500W capacity comfortably handles mainstream CPUs, single mid-range graphics cards and multiple storage drives simultaneously. It runs out when a build demands sustained loads beyond 500W such as high-end multi-GPU configurations or extreme overclocking scenarios. Builders planning such configurations will need a higher wattage platform.

Questions about this item

Will the 80 mm fan need replacement after years of continuous operation?

The built-in 80 mm fan uses automatic thermal sensing; it runs slower at low load, reducing wear and extending service life in typical daily use.

What limits sustained output when the 500 W unit runs at full load for hours?

Voltage regulation is held within 5 % tolerance on the 12 V, 5 V and 3.3 V rails, so thermal protection triggers before electrical limits are exceeded.

How much heat and noise does the supply produce during all-day operation?

The 80 mm thermal-sensing fan ramps speed only as temperatures rise, keeping acoustics low at idle and providing adequate airflow under continuous 500 W load.
