  1. Weird. #Supermicro has (had?) two different power distribution backplanes (for redundant hot-swap power supplies) for their SC825 series of 2U rackmount server cases: PDB-PT825-8820 and PDB-PT825-8824. The only difference appears to be that the -8824 has longer leads. The -8820's shorter cables won't reach the 12V CPU-power sockets on most mainboards, so I'm not sure how they could be used, and the -8824 seems to be discontinued. My -8824 broke and the replacement I received is a -8820. I have a spare for now, but would like to have one in stock, too.

  3. Electrical Faults After a Thunderstorm: What Usually Goes Wrong and Why It Happens

    After a thunderstorm, electrical faults are most often caused by voltage surges, insulation stress, or damage in the distribution network. Even if lightning does not strike a building directly, nearby strikes and grid switching can still push abnormal voltage into household wiring. The result can range from minor device malfunctions to partial or total power loss inside a home. What a Storm Actually Does to Electrical Systems A common misunderstanding is that only a direct lightning strike […]

  4. Why do PLC panels suffer from random resets, unstable inputs, or communication drops?
    In many cases, the issue is not the PLC logic — it is the 24V DC power architecture.

    We’ve published a practical technical article covering sizing, protection, DC distribution, and reliability best practices for industrial control panels.

  6. How xAI powered Colossus: 2 GW — 40% of Memphis's entire grid capacity. For one facility.

    AWS eliminated floor-level UPS, moved to rack-level. 35% less distribution loss.
    Google: 100 million Li-ion cells, 1.09 PUE.

    Power architecture defines everything.
