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. 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.

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?

Lightweight, Comfortable Hoodie That’s Great for Everyday Wear
Color: Grey Green, Size: XX-Large
This hoodie turned out to be a really solid combination of comfort, performance, and casual style. The fabric feels lightweight and breathable while still providing enough warmth for cooler mornings and evenings. I especially like how soft and stretchy it feels without being bulky. The moisture-wicking, quick-drying material works well for workouts and outdoor activities, and it also looks clean enough for everyday casual wear. I’ve worn it to the gym, while traveling, and just around the house, and it’s been comfortable in every situation. The subtly textured design gives it a more premium appearance than a standard hoodie, and the fit strikes a nice balance between relaxed and athletic. It layers easily with jackets or can be worn on its own with joggers or jeans. Another big plus is the UPF protection, which makes it useful for outdoor activities like hiking, golf, or walking around in the sun. Overall, this is a versatile, comfortable, and stylish hoodie that works great for both active and casual use. Highly recommended!

A great lightweight hoodie.
Color: Light Dark Blue Grid, Size: X-Large
Another excellent M MAELREG product. I already have some pants and jackets from M MAELREG and figured this hoodie would be great as well and I was right. It is lightweight and very comfortable while also being warm. The material is smooth and soft to the touch with a stylish look to it that would work in tthe gym, on the golf course, or out about town. I really love the hood design, not having a single hem down the center lets the hood rest more naturally on your head. It fits as expected, I would prefer it to be a couple inches longer, but that's just my personal taste. Overall, this is an excellent lightweight hoodie.

Nice hoodie, very comfortable
Color: Misty Blue, Size: Medium
This hoodie feels lightweight and breathable which makes it good for golf, workouts, or just casual everyday wear. The fabric has a soft athletic feel and stretches enough to stay comfortable while moving around. It’s lighter than a standard sweatshirt, so it works better for layering or mild weather. I liked that it didn’t feel bulky while still giving some warmth during cooler mornings. The hood lays nicely and the material dries fairly quickly if you sweat in it. It also has a cleaner athletic look that pairs well with joggers, shorts, or golf pants without looking sloppy. One thing to note is it’s thinner than some people may expect from a hoodie, so it won’t replace a heavy sweatshirt in colder weather. The fit also runs slightly slim depending on build. Still, for sports, travel, or casual wear, it’s comfortable and easy to throw on without feeling heavy.

Great lightweight fabric, good design
Color: Grey Green, Size: Small, Color: Grey Green, Size: Small
This hoodie is a great athletic top. The size small fits my husband well, although it's a little loose in the arms. So if you have a leaner figure, you may find it a bit baggy. But the fabric is fantastic, a high-quality performance fabric that seems breathable and the UV protection is a great bonus. The sleeves are long enough to make good use of the thumb holes in cooler weather, and the color is a nice neutral, gray-green. For reference, the size small has a chest of about 42" (measured just under the sleeves) and a center back length of approx. 25".

Great Quality and Look
Color: Grey Green, Size: Medium
21st century materials are here to save us! :) M Maelreg does a great job utilizing those materials to the best of their ability. I've really become a fan of just about anything that they make, and this shirt is no exception. It's made from the very popular 88/12 Poly/spandex blend that has become ubiquitous in the fitness/active industry because of its amazing tensile characteristics- wicking, quick dry, UPF, and extra comfy against the skin. You get all of that here and a no-frills, really beautiful color to go along with a fit that is exactly true to size. I took the more form-fitting version for my 5'10" 175 lb. frame (I've found both L and M work from these guys, M for a more tailored look) and it's exactly right- enough room to move around comfortably and breathe, not so tight that it's hugging my belly. It's super lightweight and really easy to launder (I hang dry mine to prevent pilling and wrinkles), cold/low and a medium/low heat iron to rid those stubborn factory wrinkles and you shouldn't ever need to iron it again. Another great offering from the folks at Maelreg.
