iEi ACE-816A AC-DC 1U Flex ATX Power Supply Repair, Replacement & Sales

The iEi ACE-816A is a 150W AC-DC 1U Flex ATX power supply designed for industrial computers, embedded systems, compact rackmount chassis, and OEM machine control platforms that require dependable multi-rail power delivery in a compact 1U form factor.

This power supply supports a selectable/wide AC input range of 95 ~ 132VAC / 181 ~ 264VAC, making it suitable for industrial applications and embedded systems that require stable operation across different regional power environments. The ACE-816A is commonly used in 1U industrial chassis, compact server-style systems, embedded computer platforms, and legacy ATX-based industrial systems that require reliable power with both standard and legacy connector support.

The unit provides the following DC output rails:

• +3.3V / 16A
• +5V / 15A
• +12V / 12A
• -5V / 0.3A
• -12V / 0.3A
• +5Vsb / 2A

The power supply also includes common industrial/ATX connector support such as:

• 20-pin ATX main connector
• 4-pin 12V CPU connector
• 2 x FDD power connectors
• 3 x HDD power connectors

With its 150W output capacity and 1U Flex ATX form factor, the iEi ACE-816A is well suited for industrial motherboards, embedded CPU boards, compact rackmount systems, storage-equipped industrial computers, and legacy ATX-based embedded platforms that require stable multi-voltage rails, including support for legacy negative voltage requirements.

At SoftTouch Technologies, we provide iEi ACE-816A repair, replacement, testing, procurement, and power integration support for customers maintaining both active and obsolete industrial systems. Whether you need a tested replacement 1U Flex ATX power supply, power rail troubleshooting, or help confirming compatibility with industrial motherboards, embedded CPU boards, and rackmount chassis systems, we can help.

iEi ACE-816A Overview

The ACE-816A is built for industrial environments that require a dependable AC-DC 1U Flex ATX power supply with dual-range AC input support, compact chassis compatibility, and multiple DC rails for embedded and industrial computer systems.

Key power supply characteristics include:

• iEi ACE-816A AC-DC 1U Flex ATX power supply
• 150W total output power
• 1U Flex ATX form factor
• Input voltage: 95 ~ 132VAC / 181 ~ 264VAC
• +3.3V / 16A output
• +5V / 15A output
• +12V / 12A output
• -5V / 0.3A output
• -12V / 0.3A output
• +5Vsb / 2A standby output
• 20-pin ATX + 4-pin 12V connector support
• 2 x FDD and 3 x HDD peripheral connectors
• Suitable for 1U industrial computers and embedded systems

Because many industrial systems rely on exact form factor fit, connector compatibility, rail stability, airflow characteristics, and startup timing, repairing the original power supply or sourcing an exact tested replacement is often the safest and most cost-effective solution.

SoftTouch Technologies ACE-816A Services

Common ACE-816A Issues We Support

• No output / no power-up condition
• Intermittent startup failures
• Low or unstable +3.3V, +5V, or +12V rails
• Missing or unstable -5V / -12V legacy rails
• Standby power (+5Vsb) failures
• Input range selection or AC acceptance issues
• Connector wear or harness related faults
• Fan or thermal shutdown issues in 1U chassis
• Overload or protection trip behavior
• Aging capacitor related instability

Typical Applications

• 1U industrial rackmount computers
• Embedded ATX and industrial motherboards
• PICMG and embedded CPU board systems
• Compact industrial control systems
• Factory automation systems
• OEM machine control platforms
• Legacy industrial workstations
• Storage-equipped industrial computers
• Data acquisition and process control systems

Why Repair or Replace the ACE-816A Instead of the Entire System?

Many industrial systems depend on exact power supply dimensions, connector layouts, rail availability, cooling constraints, 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
• Dual-range input verification (95 ~ 132VAC / 181 ~ 264VAC)
• No-load and loaded output rail verification
• +3.3V / +5V / +12V regulation checks
• -5V / -12V legacy rail verification
• +5Vsb standby rail testing
• Power-on signal and startup timing checks
• Connector output validation (ATX / CPU / HDD / FDD)
• Thermal and fan operation checks
• 1U airflow and stability validation
• Extended burn-in / soak testing when required
