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

3 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 SATA and Molex lengths run to the last plug.7Reviewkitguru.net/components/power-supplies/zardon/seasonic-core-gx-850-atx-3-reviewRead 15 October 2026Page 2 of KitGuru's CORE GX 850 review shows Seasonic's Cable Summary slide for the whole CORE GX ATX 3 family, with one column per output. The 750 W column reads: MB 610 mm 1 cable with 20+4 pins, CPU 750 mm 2 cables with 4+4 pins, 12V-2x6 700 mm 1 cable, PCIe 750 mm with 6+2 pins 0 cables, PCIe 700 mm with 16 pins to 2 x 6+2 pins 1 cable, SATA 750 mm 2 cables with 3 connectors, Molex 690 mm 1 cable with 3 connectors. The slide has no single 6+2 pin PCIe cable for the 750 W unit, so the unit has 2 PCIe 8-pin plugs on 1 cable. The Cybenetics sample lists one more single 6+2 pin cable at 750 mm, which is not stored. Cable lengths to the first plug come from the Cybenetics report for SATA and Molex, since the slide gives lengths to the last plug. The 16-pin to dual 8-pin cable shares the 12V-2x6 PSU socket with the native 12V-2x6 cable on the 850 W unit, as the page 3 photo of the modular panel shows. The same panel is expected here, but no photo of the 750 W unit confirms it.8Measurementcybenetics.com/evaluations/psus/2753Read 15 October 2026Cables and Connectors table: ATX 615 mm 16-18AWG, EPS 4+4 750 mm 16AWG (2 cables), 2x 6+2 PCIe 700 mm on one cable with two plugs 16-18AWG, a single 6+2 PCIe 750 mm cable 16-18AWG, 12+4 pin PCIe 700 mm (600W) 16-28AWG, SATA 455 mm then 155 mm then 155 mm on 2 cables (6 plugs, 18AWG), 4-pin Molex 455 mm then 125 mm then 125 mm on 1 cable (3 plugs, 18AWG). The stored ATX, EPS and 12V-2x6 lengths and the PCIe cable follow Seasonic's cable slide. The 16-28AWG range of the 12V-2x6 cable includes the thin sideband wires, so the 16AWG power wire gauge is stored. The extra single 6+2 pin cable in the sample is not in Seasonic's slide.

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.

Always on6Reviewgeeknetic.es/Review/3008/Seasonic-CORE-ATX-3-GX-750-Review.htmlRead 15 October 2026These models do not stop the fan at idle. It always runs under PWM control at about 40% PWM up to 60% load, with idle speeds of about 400 rpm.

The fan reads 864 rpm at 10% load.

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.
