myVolts WUYIN 450W 12V DC ATX Pico PSU 64x39x16mm

SKU CH-34V4-ABTY2

A 450W fanless DC-ATX pico PSU with 12V input, 24-pin output, solid polymer capacitors and full protection in a 64x39x16mm module

  • TypeAT
  • 450 W peak output from a 12 V DC source
  • Fanless design runs completely silent in any build
  • Solid polymer capacitors extend service life and reliability
  • Industrial-grade capacitors withstand high temperatures for stable operation
  • Ultra-compact 64 x 39 x 16 mm footprint fits tight spaces

Compact DC-ATX power module

This pico PSU converts a 12 V DC source into standard ATX rails with a 450 W peak rating. It is built for mini-ITX or embedded systems that run from an external brick or battery bank. The 64 x 39 x 16 mm board fits tight enclosures and uses solid polymer capacitors for durability. No fan means completely silent operation.

Ideal for space-constrained DC-powered builds

Suits builders assembling fanless HTPCs, industrial boxes or portable workstations that already have a regulated 12 V supply. Not for systems that need a full ATX supply with AC input, multiple 12 V rails or auxiliary connectors beyond the 24-pin and included cable set. Buyers wanting integrated AC-DC conversion or modular cabling should look elsewhere.

Verify your 12 V source and connector needs

Confirm the external 12 V DC source can deliver sufficient current for 450 W peak load and uses a compatible input connector. Ensure the 24-pin ATX output and supplied cable set match the motherboard and peripheral requirements. Check that the 64 x 39 x 16 mm footprint clears surrounding components in the chassis.

Questions about this item

What 12V DC power source must I already have to run this 450W pico PSU?

You need a 12V DC supply capable of delivering the current required for up to 450W output.

Will this 64x39x16mm unit fit alongside my existing ATX motherboard and 24-pin connector?

Yes, it uses a standard 24-pin ATX connector and the compact 64x39x16mm size fits mini-ITX cases.

How can I confirm the fanless 450W pico PSU is operating correctly after installation?

The system powers on stably, voltages remain steady under load, and no shutdowns occur from over-current or short-circuit protection.
