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

4 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.

The 16-28AWG range includes the thin sideband wires, so the 16AWG power wire gauge is stored. The two Molex plugs sit on the second SATA and Molex cable, so the molex row takes that cable's 510 mm to its first plug.

The datasheet gives no cable counts, lengths or gauge. Those come from the Cybenetics cable table. The Cybenetics sample had only 2 PCIe 6+2 plugs, 9 SATA plugs and 3 FDD plugs, so no cable count is stored for those rows.4Measurementcybenetics.com/evaluations/psus/2805Read 14 October 2026Cables and Connectors table: ATX 600 mm 16-20AWG, 2 EPS 650 mm 18AWG, 2 PCIe 6+2 pin 600 mm 18AWG, 12+4 pin PCIe (600W) 600 mm 16-24AWG, one cable with SATA (500 mm then 150 mm spacing) and Molex, three cables with SATA, Molex and FDD, 18-20AWG. The 16-24AWG range for the 12V-2x6 cable includes the thin sideband wires, so no gauge is stored for it. The first plug of the SATA, Molex and FDD cables is 500 mm from the PSU. Plug counts for PCIe, SATA, Molex and FDD follow the MSI datasheet because the sample differs.5Reviewhwbusters.com/psus/msi-mag-a1000gls-pcie5-atx-v3-1-psu-reviewRead 14 October 2026Cables page: the same cable table as the Cybenetics report.

Fan modeiSemi-passive means the fan stops at low load, often sold as zero RPM, hybrid or 0 dB mode. Fanless means the unit has no fan.

The review prefers a PWM fan at low speed over a fan-stop feature.

Fan mode switchiA button, switch or software setting lets the user turn the semi-passive mode off so the fan always spins. A unit without a semi-passive mode, whose fan the maker says always spins, has no switch, so it is false.

Protection and parts

1 of 3 differ

ProtectionsiProtections the maker lists, or a retailer spec table copies from the maker, plus protections the Cybenetics protection tests show working (UVP, NLO, SIP). The Cybenetics manufacturer list has no OVP or UVP row, so do not build the list from it alone. A protection that is not listed may still exist. No-load covers no-load operation and no-load protection. Fan failure is a maker's fan failure protection or fan safeguard, also when the Cybenetics manufacturer block lists it.
