The iEi ACE-A627A-RS is a 270W AC-DC 1U Flex ATX power supply designed for industrial computers, embedded control systems, rackmount chassis, and OEM platforms that require dependable multi-rail power delivery in a compact 1U form factor.

This power supply supports a wide 85 ~ 264VAC input voltage range, making it suitable for global industrial applications and embedded systems operating in demanding environments. The ACE-A627A-RS is commonly used in 1U industrial chassis, compact server-style systems, and embedded computer platforms that require reliable ATX-compatible power with multiple output rails and legacy connector support.

The unit provides the following DC output rails:

• +3.3V / 16A
• +5V / 18A
• +12V / 16A
• +12V2 / 10A
• -12V / 0.8A
• +5Vsb / 0.5A

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

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

With its 270W output capacity and 1U Flex ATX form factor, the iEi ACE-A627A-RS 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.

At SoftTouch Technologies, we provide iEi ACE-A627A-RS 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-A627A-RS Overview

The ACE-A627A-RS is built for industrial environments that require a dependable AC-DC 1U Flex ATX power supply with wide AC input support, compact chassis compatibility, and multiple DC rails for embedded and industrial computer systems.

Key power supply characteristics include:

• iEi ACE-A627A-RS AC-DC 1U Flex ATX power supply
• 270W total output power
• 1U Flex ATX form factor
• Input voltage: 85 ~ 264VAC
• +3.3V / 16A output
• +5V / 18A output
• +12V / 16A output
• +12V2 / 10A output
• -12V / 0.8A output
• +5Vsb / 0.5A standby output
• 20-pin ATX + 4-pin 12V connector support
• FDD and 3 x HDD peripheral power 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.

• Storage-equipped industrial computers
• Data acquisition and process control systems

Why Repair or Replace the ACE-A627A-RS 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 / +12V2 regulation checks
• -12V rail verification
• +5Vsb standby rail testing
• Power-on signal and startup timing checks
• Connector output validation (ATX / CPU / peripheral)
• Thermal and fan operation checks
• 1U airflow and stability validation
• Extended burn-in / soak testing when required
