Energy consumption …
The energy consumption of the PC varies depending on the hardware and load. We have listed a few interesting system configurations in the following table. When measuring the consumption of the ASRock B650 Steel Legend WiFi, all onboard components were activated and all BIOS settings were set to “Auto”. Undervolting has not yet been performed. A BeQuiet Pure Power 12 M 750W power supply, four SATA HDDs Seagate Barracuda 4 TB, a fast M.2 NVME PCIe Gen 5 SSD, 32 GB DDR5 RAM, a SATA SSD Samsung 240 GB, as well as a DVD drive, the standard AMD cooler and three case fans were installed. The energy consumption was measured in idle mode. Windows 11 in the Pro version with all current drivers was used for this. Prime95 with the “Small FFTs” option was used for the load measurement.
This resulted in the following consumption values:
