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.

Cybenetics and Hardware Busters measure 450 mm for the SATA and Molex cables and 155 mm for the SATA spacing. The maker figures are stored. The 12V-2x6 to dual PCIe cable and the native 12V-2x6 cable use the same 12V-2x6 socket, so they are alternatives.

The bundle has three single PCIe 6+2-pin cables and one cable from the 12V-2x6 socket to two 6+2-pin plugs. That cable and the native 12V-2x6 cable are alternatives, so the five legacy PCIe plugs and the native cable cannot all be used together.

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.

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.

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

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.
