  • Product typeAT
  • Industrial solid capacitors deliver stable, reliable operation at high temperatures
  • 24-pin ATX cable plugs straight in for immediate use
  • 300 W output from a 12 V DC source with required adapter
  • Over-current and short-circuit protection keeps connected hardware safe

AT Power Module for Mini-ITX Builds

The myVolts Santing 300W 12V DC AT Power Supply Module converts a 12V DC source into standard ATX voltages for compact systems. It delivers 300W output with 85% efficiency and includes industrial solid capacitors rated for 0 to 55°C operation. A 24-pin ATX cable and DC input lead are supplied for direct installation.

Suits Embedded and Space-Constrained Systems

Builders assembling Mini-ITX, 1U, HTPC, POS, digital signage or thin-client platforms will find the 154 x 35 x 15mm board fits tight enclosures. Over-current and short-circuit protection safeguard connected hardware. Not suitable for builds that require standard AC input or ATX-form-factor power supplies.

Requires 12V DC Source Up to 25A

The module accepts 11.4-12.6V DC input and draws a maximum of 25A, so the external adapter or battery must sustain that current continuously. Without a capable 12V DC source the unit cannot deliver its rated 300W output.

Questions about this item

Should I pick a higher-wattage version for a mining rig or a lower one for a simple HTPC?

This module is a single 300 W design; there are no alternative capacities listed, so you match the 300 W rating to your build's total draw.

What does the 300 W output actually deliver when the board is running inside a 1U case at full load?

It converts a 12 V DC source (11.4–12.6 V, up to 25 A) into ATX rails at 85 % efficiency, giving up to 300 W continuous while the case stays within 0–55 °C.

The board takes a 12 V DC input — what connector standard does that use and what current limit does it enforce?

A dedicated DC input cable plugs into the module; the input is rated for a maximum of 25 A at 12 V, capping the available power at the source.
