Cybenetics offers ETA and LAMBDA certifications, evaluating PSU efficiency and noise output. ETA rates PSUs not only based on efficiency but also on power factor, 5VSB efficiency, and vampire power.

A new tier of power supply efficiency could help data centers save more power, cutting energy costs and energy demand from one of the fastest-growing heavy-power-use industries. The new 80+ Ruby ...

Navitas Semiconductor announced that its GaNSafe and Gen 3 Fast SiC MOSFETs enable their portfolio of 3.2-kW, 4.5-kW, and 8.5-kW AI data center power supply unit (PSU) reference designs to achieve the ...

Even if you don’t have a Rohde Schwarz oscilloscope, you can still enjoy their recent video about using an oscilloscope to measure power supply efficiency. Of course, you don’t have to have a scope to ...

PCWorld explains that selecting a PC power supply in 2026 has become surprisingly complex due to new technologies like ATX 3.0/3.1 standards and 16-pin GPU connectors. Modern high-end graphics cards ...

80+ efficiency is measured down to 20% load except for Titanium which also measures down to 10% load. But that’s not necessarily helpful for systems that operate in the under-50W range. Looking at ...

Power Supply Units (PSUs) are responsible for giving life to all the components inside a PC. They supply power to the CPU, GPU, storage drives, motherboard, and all components connected to the ...

Users in industrial control and info-communication fields are placing growing importance on the durability and reliability of power supplies. However, legacy power supply units (PSUs) are facing ...

Everything else relies on it, and it's the most likely point of failure for an old repurposed PC ...

The PSU or Power Supply Unit is what brings every component of a computer to life. As the name suggests, it relays power from the wall to the different components of a computer, depending on how much ...
