BFKK 320W ATX Power Supply CN32.7

SKU CH-2QZD-5DP8P

320W ATX power supply with dual 12V rails, 20+4 pin motherboard connector, 4-pin CPU connector and two SATA connectors

  • Delivers 320W continuous power for stable system operation
  • ATX form factor fits standard desktop chassis
  • Dual 12V rails distribute load evenly across components
  • 20+4 pin and 4-pin CPU connectors support modern motherboards
  • Two SATA connectors power storage drives directly

Direct replacement for Shuttle XPC

This 320W ATX power supply carries the CN32.7 part number and matches the original unit used in Shuttle XPC SG33G5, SK22G2B and SK22G2 small-form-factor systems. It delivers 320 watts across two 12 volt rails and uses a fixed cable layout. The unit is intended for owners restoring or maintaining those specific Shuttle barebones platforms.

Steady output on dual 12V rails

Under sustained load the two 12 volt rails share the 320W budget without the transient spikes seen in single-rail designs. Fixed wiring keeps resistance predictable over long sessions. The supply is not redundant and has no modular connectors, so every cable remains in circuit at all times.

Fits the original mounting points

Installation uses the stock ATX screw pattern and the 20+4 pin motherboard connector plus a single 4 pin CPU plug. Two SATA connectors power drives directly. Builders who need more SATA ports or a modular cable set cannot use this unit. Cable length is set for the Shuttle chassis and may not reach in larger cases.

How much heat does the 320W ATX supply produce when running continuously?

The unit delivers 320 W through two 12 V rails; heat output scales with the load you place on those rails.

Which motherboard and CPU connectors must my system already provide for this supply to fit?

It requires a 20+4 pin main connector and a 4 pin CPU connector on the board.

Will the two SATA connectors power the older drives I plan to keep?

Yes, the two SATA connectors supply standard power to compatible drives.
