ACE-916A

iEi ACE-916A AC-DC AT Power Supply Repair, Replacement & Sales

The iEi ACE-916A is a 150W AC-DC AT power supply designed for industrial computers, embedded systems, legacy automation platforms, and OEM machine control systems that require dependable multi-rail power delivery and long-term service support.

This power supply supports a wide 90 ~ 264VAC full range input voltage, making it suitable for global industrial deployments and systems that require stable operation across varying AC power environments. The ACE-916A is especially useful in legacy industrial computer systems that depend on AT power architecture and classic peripheral power connections.

The unit provides the following DC output rails:

• +5V / 15A
• +12V / 10A
• -5V / 0.3A
• -12V / 0.3A
• +24V output

The power supply also includes legacy connector support such as:

• P8 / P9 AT power connectors
• FDD power connector
• 3 x HDD power connectors

With its 150W output capacity, the iEi ACE-916A is well suited for embedded CPU boards, industrial motherboards, passive backplane systems, storage devices, and legacy peripheral loads that require stable multi-voltage rail support.

At SoftTouch Technologies, we provide iEi ACE-916A repair, replacement, testing, procurement, and power integration support for customers maintaining both active and obsolete industrial systems. Whether you need a tested replacement AT power supply, power rail troubleshooting, or help confirming compatibility with embedded boards, industrial motherboards, and legacy AT systems, we can help.

iEi ACE-916A Overview

The ACE-916A is built for industrial environments that require a dependable AC-DC AT power supply with full-range AC input support, legacy AT connector compatibility, and multiple DC rails for embedded and industrial computer systems.

Key power supply characteristics include:

• iEi ACE-916A AC-DC AT power supply
• 150W total output power
• Input voltage: 90 ~ 264VAC full range
• +5V / 15A output
• +12V / 10A output
• -5V / 0.3A output
• -12V / 0.3A output
• +24V output
• P8 / P9 AT power connectors
• FDD and 3 x HDD peripheral connectors
• Suitable for legacy industrial computers and embedded systems

Because many industrial systems rely on exact power supply dimensions, connector compatibility, rail stability, and startup behavior, repairing the original power supply or sourcing an exact tested replacement is often the safest and most cost-effective option.

SoftTouch Technologies ACE-916A Services

• ACE-916A power supply diagnostics and repair
• Tested surplus and refurbished replacement AC-DC AT power supplies
• Output rail verification and load testing

Common ACE-916A Issues We Support

• No output / no power-up condition
• Intermittent startup failures
• Low or unstable +5V or +12V rails
• Missing or unstable -5V / -12V legacy rails
• +24V rail instability
• Connector wear or harness related faults
• Overload or protection trip behavior
• Aging capacitor related instability
• System reset or reboot caused by poor rail regulation
• Legacy AT system startup issues

Typical Applications

• Legacy industrial computers
• Embedded CPU boards and industrial motherboards
• PICMG and passive backplane systems
• Factory automation systems
• OEM machine control platforms
• Legacy industrial workstations
• Data acquisition and process control systems
• Retrofit and long-life industrial computing systems

Why Repair or Replace the ACE-916A Instead of the Entire System?

Many industrial systems depend on exact power supply dimensions, connector layouts, rail availability, and predictable startup behavior. Replacing the entire system because of a failed power supply can create unnecessary cost, compatibility risk, and downtime. In many cases, the best option is to repair the original power supply or source a tested exact replacement that preserves the existing system architecture.

Bench Testing & Functional Validation

Before shipment or after repair, we can perform functional validation such as:

• AC input acceptance testing
• No-load and loaded output rail verification
• +5V / +12V regulation checks
• -5V / -12V legacy rail verification
• +24V output verification
• P8 / P9 connector output validation
• FDD and HDD connector checks
• Thermal and stability checks
• Extended burn-in / soak testing when required
