WMtec DPS-400AB-12 B 1U Server Power Supply 400W

This WMtec server power supply delivers 400W in a 1U form factor measuring 150*80*40MM. It suits compact ITX, FLEX and HTPC chassis such as K39, K49, M41 and similar small enclosures. The unit targets builders of cash registers, arcade cabinets and other specialised single-purpose machines.

Check 24-pin and 4+4-pin CPU connectors match your

Verify the motherboard accepts both 24-pin ATX and dual 4+4-pin CPU power cables. Confirm the chassis can house a 150*80*40MM 1U unit and that airflow aligns with the supply’s exhaust direction. Ensure SATA and IDE device counts fit the three SATA and two IDE leads provided.

Replaces older 1U units in ITX FLEX HTPC builds

This supply upgrades ageing 1U units in ITX FLEX HTPC cases like K39, K49, M41 and related models. The jump is worth it when the original unit fails or cannot feed modern CPU and GPU loads through dual 4+4-pin CPU and 6+2-pin graphics connectors. It also adds SATA support for newer storage.
