iEi ACE-720APM 1U AC Input ATX Power Supply Repair, Replacement & Sales

The iEi ACE-720APM is a 200W 1U AC input ATX power supply designed for industrial computers, rackmount embedded systems, OEM machines, and compact automation platforms that require reliable multi-rail power delivery in space-constrained chassis.

This power supply accepts a wide 85 ~ 264VAC input voltage range, making it suitable for global industrial deployments and systems that require stable operation across varying AC power conditions. The ACE-720APM is commonly used in 1U industrial chassis, embedded computer platforms, and legacy ATX-based systems that depend on dependable multi-voltage rail support.

The unit provides the following DC output rails:

• +3.3V / 20A
• +5V / 20A
• +12V / 9A
• -5V / 0.5A
• -12V / 0.5A
• +5Vsb / 0.5A

With its 200W output capacity and 1U form factor, the iEi ACE-720APM is well suited for rackmount industrial systems, embedded motherboards, compact server-style industrial platforms, and legacy peripheral loads that require stable multi-voltage power rails.

At SoftTouch Technologies, we provide iEi ACE-720APM repair, replacement, testing, procurement, and power integration support for customers maintaining both active and obsolete industrial systems. Whether you need a tested replacement 1U ATX power supply, power rail troubleshooting, or help confirming compatibility with industrial motherboards, embedded CPU boards, and 1U chassis systems, we can help.

iEi ACE-720APM Overview

The ACE-720APM is built for industrial environments that require a dependable 1U AC input ATX power supply with wide AC input support and multiple legacy DC output rails for industrial and embedded computer systems.

Key power supply characteristics include:

• iEi ACE-720APM 1U AC input ATX power supply
• 200W total output power
• 1U power supply form factor
• Input voltage: 85 ~ 264VAC
• +3.3V / 20A output
• +5V / 20A output
• +12V / 9A output
• -5V / 0.5A output
• -12V / 0.5A output
• +5Vsb / 0.5A standby output
• Suitable for 1U industrial computers and embedded systems

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

• Retrofit and long-life industrial computing systems

Why Repair or Replace the ACE-720APM 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
• 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
• Thermal and fan operation checks
• 1U airflow and stability validation
• Extended burn-in / soak testing when required
