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

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.

Tech Specs: SATA connector 6, PATA connector 2. PCIe 8-pin is 1 single cable plus 1 cable with two 8-pin plugs, so 3 plugs on 2 cables. The two 4-pin PATA plugs are the molex row, which takes the 450 mm to the first plug of that cable. The 12V-2x6 cable is described as a native 600W-capable cable. The wire gauges come from the Cybenetics report. The quick start guide lists 2 single 8-pin PCIe cables for this model, which does not match this table, the Cybenetics report or Hardware Busters. The PSU side has one 12V-2x6 socket, so the dual 8-pin cable takes the 12V-2x6 socket and cannot be used together with the native 12V-2x6 cable. Cybenetics measures 600 mm, 740 mm, 640 mm and 445 mm for some of the same cables, which are not stored.5Measurementcybenetics.com/evaluations/psus/2625Read 16 October 2026Cables and Connectors table gives wire gauge per cable: ATX 18-20AWG, EPS 18AWG, 6+2 PCIe 18AWG, 2x 6+2 PCIe 16-18AWG, 12+2 pin PCIe (600W) 16-24AWG, SATA and Molex 18AWG. The 16-24AWG range for the 12V-2x6 cable includes the thin sideband wires, so no gauge is stored for it. Lengths are Corsair's.

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.

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.

The manual lists no OCP, OTP or UVP.

All-Japanese capacitorsiThe maker states that every electrolytic capacitor is from a Japanese maker. A Japanese bulk capacitor alone is not enough. A spec row such as "Japanese capacitors" that names no exception counts.
