The Blackmagic Design Spares - ATEM Constellation 8K - PSU 400W is the internal high-capacity power supply module for Blackmagic's flagship 8K switcher. Because the Constellation 8K handles a massive amount of data processing (40 inputs, 24 outputs, and 4 M/Es in 8K), it has significant power requirements and generates considerable heat.

To ensure professional-grade reliability, the Constellation 8K actually houses two of these 400W modules for redundancy.

Core Responsibilities

  • Load Balancing: When both PSUs are healthy, they share the power load, which reduces heat stress and extends the lifespan of the individual components.

  • Redundancy (Fail-Safe): If one PSU fails, the second 400W module is capable of powering the entire 2RU chassis alone, allowing the broadcast to continue without interruption.

  • Multi-Rail Output: Converts AC mains power into the specific DC voltages required for the high-performance FPGAs, the 40 BNC input engines, and the internal cooling fans.

  • Protection Circuitry: Includes built-in fuses and thermal shut-off to protect the expensive Main PCB from power surges or over-voltage events.

When to Replace the 400W PSU

  • "PSU Failed" Alert: The ATEM Software Control or the front panel LCD displays a "Power Supply Failed" warning.

  • Loud Fan Noise / Clicking: If a PSU is failing, its internal cooling fan may struggle, or you may hear electrical "clicking" (relays firing) as it attempts to stabilize voltage.

  • Intermittent Power-Offs: The unit randomly shuts down or reboots, especially when under heavy processing loads (e.g., using all 4 M/Es or complex DVEs).

  • Input/Output "Glitching": While usually a logic issue, a "sagging" power supply can cause digital noise on the SDI outputs before the board completely fails.

Technical Installation Note

Repair Level: 2 (Moderate).

  1. Dual AC Inputs: Remember that the Constellation 8K has two separate AC power inlets. Unplug both before opening the unit.

  2. Modular Swap: These PSUs are typically modular. They are secured to the floor of the chassis with screws and connected to the main distribution board via a heavy-duty wiring harness.

  3. Thermal Clearance: Ensure the replacement PSU is seated correctly. Any obstruction of the PSU's dedicated air path will cause the new unit to overheat quickly in a 2RU rack.

  4. Harness Verification: Ensure the multi-pin connector is pushed in until it clicks. A loose high-amperage connection can cause arcing, which will melt the plastic connector over time.

Diagnostic: PSU 1 vs. PSU 2

The Constellation 8K identifies which power supply is failing in the menu. You can verify this by:

  1. Unplugging AC Cord 1. If the unit stays on, PSU 2 is healthy.

  2. Unplugging AC Cord 2 and plugging back in Cord 1. If the unit stays on, PSU 1 is healthy.

  3. If the unit dies during either test, you have identified the dead module.

Expert Advice: If one PSU has failed after years of service, it is often best practice to replace both. Since they have likely been running for the same number of hours, the second PSU is often nearing its end of life as well.

Has one of your redundant power indicators turned red on the front panel, or is the entire unit failing to power up?
