Blackmagic Design Spares - ATEM Constellation 8K - PSU 400WThe Blackmagic Design Spares ATEM Constellation 8K PSU 400W is the internal high capacity power supply module for Blackmagic's flagship 8K switcher.

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?

My Heels Were in Bad Shape. Like… Really Bad
Color: Gray
These moisturizing heel socks with the gel cushions were honestly a small miracle for me. After recovering from cancer treatments, my skin became extremely dry everywhere, but my heels were the worst. They cracked so deeply they looked like fissures and were even bleeding. I tried lotions and bandages repeatedly with very little progress. A friend suggested I treat my heel like it might have a fungal component, so I applied Lotrimin cream, put these heel socks on, and hoped for the best. Within three days, my heels were fully healed. I completed a 7-day routine, and my feet have never been softer. The silicone gel cushion is comfortable, soothing, and stays in place. I loved it so much that I still treat myself about once a week, even though I really don’t need to anymore. They are also washable. I hand-washed mine in the sink and let them air dry, and they came out looking brand new. If your heels are cracked, painful, or need serious care, I highly recommend these.

Ehh. Not for me.
Color: Gray
Foot slides when walking in them. The fit was tighter than lead to believe. It did hold the moisture in but the silicone patch is small

I recently purchased Dr. Frederick's Original Moisturizing Heel Socks, and they have truly transformed the condition of my feet! I can’t recommend them highly enough.

My feet feel softer and smoother, and I love that I can wake up to beautifully moisturized skin. Comfortable Fit: The socks are incredibly comfortable to wear, with a snug yet gentle fit. I appreciate that they don’t feel restrictive, allowing me to walk around my home while wearing them without any discomfort. They are also lightweight, making them easy to slip on before bed. User-Friendly: They are super easy to use—just wear them overnight, and let the socks do their magic. I love the simplicity of incorporating them into my nighttime routine. Durable Quality: The quality of the socks is impressive. They wash well and have maintained their shape and effectiveness after multiple uses. I feel confident that they will last a long time.

These worked for me!
Color: Original Grey
They worked great. I bought these for cracked sore heels. It took 2-3 weeks but my heels no longer hurt and the cracks have closed and look more like an indention than a crack now. They feel so much better, but I'll probably wear them another week just to be sure they stay healed. They look and feel like regular socks from the outside but only cover the heel with the toe open. Not think but not thick, again like regular socks. They would probably be slippery on a smooth surface the same as socks. The inside feels like rubber or something smooth at the heel. I have washed them once each pair and accidentally dried one pair in the dryer. They still seem to feel the same so I think they're fine. They're pretty inexpensive and had different colors and sizes.
