MEAN WELL GS90A12-P1M 12V 80W Table-Top Power Supply - Reliable 3-Wire

In this review the MEAN WELL GS90A12-P1M is presented as a compact, regulated table-top power supply aimed at small labs, bench projects, and embedded systems that need a steady 12V source. The single biggest reason to buy is its reliable regulated output of 12 volts at up to 6.67 amps in a small 5.7in x 2.3in x 1.3in package, which makes it useful where wall-wart adapters struggle to deliver consistent current under load. The review focuses on build, performance, and practical details such as connector type and cord length.

Key Features

• Regulated 12V Output: Provides a steady 12 volts at up to 6.67 amps so devices run without voltage sag under moderate loads.
• Wide AC Input Range: Accepts 90-264Vac at 47-63Hz, making it suitable for use in locations with varied mains voltages without a separate transformer.
• Compact Table-Top Design: The small footprint of 5.7in L x 2.3in W x 1.3in H keeps bench space clear while still delivering 80W of power.
• Standard DC Connector: Uses a 2.5mm x 5.5mm straight female center-positive plug, which fits many consumer electronics and development boards without adapters.
• Four-Foot DC Cord Included: Comes with a 4 ft DC output cord for immediate use out of the box, minimizing cable clutter on a workbench.
• Agency Approvals: Safety approvals (Ulf/Cull/Tuv/Cec) indicate it meets common regulatory standards for commercial and lab use.

Who It's For

The GS90A12-P1M is best for hobbyists, engineers, or technicians who need a reliable external supply for routers, single-board computers, LED drivers, or small lab instruments that draw under 6.67 amps. Its regulated output and standard barrel connector make it a practical drop-in replacement for lesser wall adapters.

It is less suitable for users who need an integrated AC input cord included or those requiring adjustable voltage or higher current beyond 6.67 amps. If you need variable output, rack-mounted supplies, or very compact USB-only chargers, look at other options.

Pros & Cons

Pros

• Reliable regulated 12V output that maintains voltage under load for consistent device operation.
• Wide 90-264Vac input range that supports international mains without additional hardware.
• Compact, lightweight table-top form factor that fits on crowded benches and comes with a 4 ft DC cord.
• Recognized agency approvals give added confidence for lab and demo use.

Cons

• AC input cord not included, so a separate 3-conductor AC power cord is recommended for immediate use.
• No adjustable voltage or current limiting features for more advanced bench work.

Frequently Asked Questions

Does this supply include an AC input cord?
It does not include the AC input cord; a separate 3-conductor AC power cord is recommended (p/n: 38050 or equivalent).

What size DC plug does it use?
The output uses a 2.5mm x 5.5mm straight female barrel with center positive, common on many devices.

Is it safe for international use?
Yes; the wide 90-264Vac input at 47-63Hz and agency approvals mean it will work on most international mains without a transformer.
