Compact power for small builds

This 220W Flex ATX supply targets mini ITX systems that need a fully modular cable set. Active PFC and 85 percent efficiency keep heat low in tight cases while meeting UL 62368 safety standards. The 24+8 pin main connector and single SATA power lead cover essential components in a space-saving footprint.

Capacity and headroom

Continuous output reaches 220W with the +12V rails providing the bulk of that power for CPU and GPU loads. Efficiency exceeds 90 percent at typical loads, reducing waste heat when the system runs near its limit. Above that ceiling the OPP and OCP circuits trip, so the unit suits builds that stay within the rated envelope.

Upgrade path and fit

Replaces non-modular or lower-efficiency Flex ATX units that clutter small chassis with fixed cables. The jump makes sense when a build needs cleaner routing, active PFC for stable mains input, or the comprehensive OTP OVP OCP OPP protection suite. Systems requiring more than 220W or additional SATA connectors will need a larger form factor.

Questions about this item

Will the 24-pin and 8-pin connectors fit my older Mini-ITX motherboard?

The 24+8 pin main connector matches the standard ATX layout used on most Mini-ITX boards, so it will plug in directly without adapters.

How can I verify the unit is delivering stable power once installed?

The active PFC circuit and 80 PLUS certification ensure consistent delivery; you can confirm operation by checking that the system posts and runs without unexpected shutdowns under load.

Which cables come in the box and what must I source separately?

The fully modular design includes a 24+8 pin motherboard cable and one SATA power cable; any additional PCIe or peripheral cables required by your build must be purchased separately.
