BFKK 300W FlexATX Power Supply AM630BS20S

SKU CH-RF2D-EFQKY

300 W FlexATX power supply for Achme AM630BS20S with 20+4 pin, 24 pin, 4 pin 12 V and SATA connectors

  • 300 W continuous power for stable system operation
  • 320 W peak capacity handles sudden load spikes
  • Single fan cooling keeps temperatures in check
  • Multiple ATX connectors fit 20-pin, 24-pin and 20+4-pin boards
  • 4-pin 12 V plus SATA and peripheral plugs cover CPU and drives

What this power supply does

This 300W FlexATX unit replaces the original Achme AM630BS20S module found in Shuttle CN30.3 systems. It delivers up to 320W maximum power through a single cooling fan and carries the MPN references AM618BS15S and AM630BS20S. The unit is listed as new condition and was first catalogued by the manufacturer in 2023.

Connector set and upgrade scope

The supply provides 20+4 pin, 20 pin and 24 pin main power options plus a 4 pin 12V connector, 4 pin peripheral leads and SATA power plugs. This combination covers the motherboard, CPU auxiliary and drive power needs of the target Shuttle chassis. Builders whose systems require additional PCIe power connectors or higher wattage than 320W peak will need a different form-factor solution.

Installation notes

FlexATX dimensions match the original bracket so the swap is a direct mechanical fit. Route the 20+4 pin, 24 pin or 20 pin main cable according to the motherboard socket present, attach the 4 pin 12V CPU lead and connect SATA drives as required. The single fan draws air through the chassis vent; ensure that opening stays clear or temperatures will rise under sustained load.

Questions about this item

What clearance does the single fan require inside the FlexATX chassis?

The unit uses one fan for cooling; allow space at the rear vent so airflow is not blocked by cables or the case wall.

Which connector must be seated first to avoid a no-post condition?

Insert the 20+4 pin main connector fully until the latch clicks, then attach the 4-pin 12V plug before powering on.

When should the 300W FlexATX supply be replaced if the fan noise increases?

Rising fan noise usually means bearing wear; swap the unit once the sound becomes noticeable under normal load.
