  • TypeAT
  • Designed for HK300-41GP MATX-2005 systems
  • 200 W output powers small-chassis builds
  • SFX form factor fits HK280-41GP cases
  • AT type ensures standard compatibility

Purpose-built replacement for HK300

This power supply is a direct-fit unit for the HK300-41GP MATX-2005 and HK280-41GP small-form-factor cases. It delivers 200 W through an AT-type design that matches the original electrical and mechanical specification. Builders restoring or servicing those specific chassis will find the correct connector layout and mounting points already aligned.

Standard SFX mounting with fixed cables

Installation follows the usual SFX screw pattern, so the unit drops into the chassis without adapters. The fixed cable set is routed for the original HK300 and HK280 harnesses, but it lacks modular plugs and may not reach motherboard headers in non-standard layouts. Builders using other cases or custom backplanes should verify connector lengths before fitting.

Questions about this item

How do I verify the 200 W myVolts unit is working after fitting it in the HK300-41GP chassis?

Power the system on; the motherboard should POST, fans spin and drives spin up without shutdowns or instability under load.

What cables come with the HK280-41GP SFX supply and what must I source separately?

The unit includes its fixed AT-type cable harness for motherboard and drive power; an SFX-to-ATX mounting bracket is not included and must be bought separately.
