Full power rated up toiThe ambient temperature up to which the maker rates full continuous power, such as 50 °C. A review table that prints 0-50 °C with no maker source is not enough. An operating temperature range that does not say full power is not enough. A maker table with load steps gives the full-load row, such as 40 °C at full load next to 50 °C at 80 percent load. A temperature that a Cybenetics report marks as manufacturer-provided counts as a maker statement.

Cables and connectors

5 of 7 differ

CablesiOne row per kind of cable that runs from the PSU to a device. Connector is the plug at the device end. Count is the number of those plugs over all cables in the row. Length runs from the PSU end to the first plug. Adapters that plug into other cables are left out. Use 16-pin PCIe when the maker names a 16-pin GPU cable without saying 12V-2x6 or 12VHPWR. A cable from a 12V-2x6 socket on the PSU to 8-pin plugs is a cable, not an adapter, and counts as PCIe 8-pin. When the maker's documents name one GPU cable both 12VHPWR and 12V-2x6, use 16-pin PCIe and name both in the source note. Cables of one connector kind with different lengths or wire gauges get one row each.

1.76kg(3.9 lb)9Reviewhwbusters.com/psus/be-quiet-pure-power-13-m-850w-atx-v3-1-psu-reviewRead 14 October 2026Technical specifications: 1.76 kg (3.88 lb). The review does not say whether cables are included. Retailers list 2.62 kg, which is most likely the packed weight. The same review site gives 1.75 kg for the 1000W model, which is a 10 g difference in the wrong direction and is probably a weighing tolerance.
