myVolts 160W PicoPSU 12V 24-pin ATX power supply

SKU CH-Y3R5-FBY2T

Converts a single 12 V source into a 160 W ATX supply with 24-pin, 4-pin, SATA and PATA outputs in a 5.4 × 3.3 × 1 cm board

  • Product typeAT
  • Delivers 160 W from a 12 V source
  • Above 92 % efficiency keeps heat low
  • 4 × 3.3 × 1 cm fits tight builds
  • Includes SATA, 4-pin AUX and PATA leads
  • MTBF rated 90 000 hours at 0–40 °C

Compact 12 V DC-DC ATX supply

This 160 W PicoPSU plugs directly into a 24-pin ATX header and draws power from a single 12 V source through a 5.5 mm barrel jack. It targets builders of silent Mini-ITX, HTPC or 1 U server systems who want to avoid a full-size PSU and its cables. The board measures approximately 5.4 by 3.3 by 1 cm and includes a 4-pin AUX, SATA and 4-pin PATA connectors.

Practical limits of the 12 V input

The unit accepts a maximum input current of 15 A, so the external 12 V brick or battery must sustain that load without voltage sag. Efficiency is rated above 92 percent, yet waste heat still appears inside the case because there is no onboard fan. Operating temperature range is 0 to 40 °C and storage range is -20 to 80 °C, so adequate chassis airflow is required for continuous high-load use.

160 W total output decides suitability

The 160 W DC output ceiling is the single figure that determines whether this converter fits a build; systems with discrete graphics cards, multiple drives or high-TDP CPUs will exceed it. Over-voltage protection is present on the DC outputs, and mean time between failures is quoted as 90 000 hours. Buyers needing more than 160 W must choose a larger power solution.

Questions about this item

Should I pick the 160 W version for my build?

The unit delivers up to 160 W from a 12 V source and draws a maximum of 15 A, so choose it only if your total system draw stays below that limit.

What does the 160 W rating mean once the PicoPSU is installed?

It means the converter can supply a continuous 160 W to the motherboard and drives while operating at above 92 % efficiency between 0 °C and 40 °C.

What does the 5.5 mm / 2.5 mm DC jack limit in practice?

The barrel connector accepts a single 12 V supply up to 15 A, capping total input power at 160 W for the 24-pin ATX, 4-pin AUX, SATA and PATA outputs.
