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.

Semi-passive2Reviewtomshardware.com/pc-components/power-supplies/cooler-master-mwe-gold-750-v4-power-supply-reviewRead 15 October 2026Cold test: the Zero RPM mode keeps the fan stopped up to almost 40% load, roughly 300 W, and the fan spins up at about 40% load. The maker page does not mention a semi-passive mode.

Not available

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.

No2Reviewtomshardware.com/pc-components/power-supplies/cooler-master-mwe-gold-750-v4-power-supply-reviewRead 15 October 2026External Appearance: there is no switch for the semi-passive fan mode. The Zero RPM behavior is automatic and not user-selectable.

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.

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.

MTBF (claimed)iThe maker's mean time between failures, such as 100000. An MTTF figure for the whole unit counts too. An MTTF for the fan alone does not. The test temperature goes in the source note.

WeightiWeight of the unit alone. Use the Hardware Busters figure on hwbusters.com when the maker states none, not a copy on another site. Maker weights that include cables or the box, such as Corsair's, and retailer packed weights are not stored. A net weight counts unless the maker says it includes the cables.
