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.

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 Inside the Box list gives 3 SATA cables and 1 peripherals cable. The overview says each 12V-2x6 cable can deliver over 600 watts. Gauges and the 150 mm spacing come from the Cybenetics report. The 4+4-pin and 8-pin CPU cables are one row of two cables, both 700 mm.2Measurementcybenetics.com/evaluations/psus/2444Read 15 October 2026Cables and Connectors table: ATX 16-20AWG, 4+4 pin EPS12V 16AWG, 8 pin EPS12V 16AWG, 6+2 pin PCIe 16AWG, 12+4 pin PCIe (600W) 16-24AWG, SATA 18AWG, Molex 18AWG, no in-cable capacitors. SATA spacing is 500 mm + 145 mm x3, Molex 500 mm + 150 mm x3. The 16-24AWG range for the 12V-2x6 cable includes the thin sideband wires, so no gauge is stored for it.

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-passive1Maker product pagenzxt.com/products/c1500-platinumRead 15 October 2026FAQ: zero fan mode keeps the fan off until system load reaches 60%.

The manual does not say how the system is turned on or off.

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.

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.

Yes1Maker product pagenzxt.com/products/c1500-platinumRead 15 October 2026Tech Specs overview: constructed using all 105C Japanese capacitors. The Cybenetics parts list also shows 7 FPCAP polymer capacitors, which the maker's statement does not address.
