SFX-to-ATX adapter for smaller power supplies

This bracket lets builders install an SFX or SFX-L power supply into a standard ATX or Micro-ATX case. The 0.8mm SECC steel plate aligns the smaller unit with the larger PS2 mounting pattern. It is intended for system integrators and enthusiasts fitting compact PSUs into full-size chassis.

Fixed mounting pattern limits case compatibility

The adapter matches the ATX (PS2) hole spacing exactly, so it only fits cases that use that standard layout. Proprietary or non-standard PSU brackets will not accept it. The plate adds 0.39 inches of depth, which can reduce clearance for cables or drive cages behind the power supply.

Offset design increases usable space inside the case

The bracket shifts the SFX power supply away from the motherboard tray, creating extra room for routing cables or installing longer expansion cards. This single geometric feature determines whether the adapter solves the clearance problem in a specific build.

Questions about this item

Should I pick this adapter for an SFX or SFX-L power supply?

The bracket accepts both SFX and SFX-L units, so either form factor will mount securely.

What does the offset design actually do inside my case?

It shifts the SFX power supply away from the standard ATX mounting plane, freeing extra room for cables or longer graphics cards.

How does the ATX (PS2) mounting pattern limit where I can install this?

The adapter uses the standard ATX screw spacing, so it fits most ATX and Micro-ATX cases that have those mounting holes.
