Avalon Miner A1446-130T Power Supply Replacement Guide

The Avalon Miner A1446-130T has solidified its position as a top-tier ASIC miner in the competitive world of cryptocurrency mining. With its impressive 130TH/s hashrate and energy-efficient design, it’s a favorite among professional mining operations and serious enthusiasts alike. However, like all mining hardware, the power supply unit (PSU) is a critical component that ensures stable and efficient operation. Over time, PSUs may require replacement due to wear and tear or increased operational demands. This guide will walk you through the process of replacing the power supply for your Avalon Miner A1446-130T, ensuring your mining operation continues to run smoothly.

Why Power Supply Replacement Matters

The power supply is the lifeblood of any mining rig, converting AC power from your electrical source into the DC power required by the miner. For the Avalon Miner A1446-130T, the PSU must deliver a stable 3360W (±5%) to maintain optimal performance. A failing or inadequate PSU can lead to:

• Reduced hashrate or inconsistent performance
• Frequent shutdowns or overheating
• Potential damage to the miner’s internal components

Replacing the PSU with a compatible, high-quality unit ensures your miner operates at peak efficiency, minimizing downtime and maximizing profitability.

Choosing the Right Power Supply

Before diving into the replacement process, it’s crucial to select a PSU that meets the specific requirements of the Avalon Miner A1446-130T. Here’s what to look for:

1. Wattage: The PSU must support a minimum of 3360W to handle the miner’s power consumption.
2. Voltage Range: Ensure compatibility with the miner’s input voltage range of 200-300V AC.
3. Connectors: Verify that the PSU includes the necessary connectors for the miner’s power input ports.
4. Quality and Reliability: Opt for professional-grade PSUs from reputable brands to ensure durability and safety.

Avalon recommends using their dedicated PSUs or high-quality third-party alternatives that meet these specifications.

Step-by-Step Power Supply Replacement Guide

Tools and Equipment Needed

• Compatible PSU for Avalon Miner A1446-130T
• Screwdriver set
• Anti-static wrist strap (optional but recommended)
• Clean, flat workspace

Step 1: Power Down and Disconnect

1. Shut down the miner: Use the control interface or disconnect power to safely shut down the miner.
2. Disconnect the power cord: Unplug the miner from the electrical outlet to ensure no power is flowing to the unit.
3. Allow cooling: Give the miner time to cool down if it was recently in operation.

Step 2: Remove the Old Power Supply

1. Locate the PSU: The power supply is typically housed in a separate compartment or attached to the miner’s chassis.
2. Disconnect cables: Carefully remove all power cables connected to the miner, noting their positions for reassembly.
3. Unscrew the PSU: Use a screwdriver to remove the screws securing the PSU to the miner.
4. Remove the PSU: Gently slide the old PSU out of its compartment, taking care not to damage surrounding components.

Step 3: Install the New Power Supply

1. Position the new PSU: Align the new PSU with the mounting points in the miner’s chassis.
2. Secure the PSU: Use the screws to firmly attach the new PSU in place.
3. Connect the cables: Reattach the power cables to the miner, ensuring each connector is properly seated.

Step 4: Power Up and Test

1. Double-check connections: Verify that all cables are securely connected and there are no loose screws.
2. Reconnect the power cord: Plug the miner back into the electrical outlet.
3. Power on the miner: Turn on the miner and monitor its startup process for any issues.
4. Check performance: Use the miner’s interface to confirm that it’s operating at the expected hashrate and power consumption levels.

Tips for Maintaining Your Power Supply

• Monitor power usage: Keep an eye on the miner’s power consumption to detect any anomalies that could indicate PSU issues.
• Ensure adequate cooling: Proper ventilation helps prevent overheating, which can extend the lifespan of the PSU.
• Use surge protectors: Protect your PSU from voltage spikes by using high-quality surge protectors.
• Regular inspections: Periodically check the PSU and its connections for signs of wear or damage.
