The PCIe row reads 2x 6+2 pin PCIe (750 mm) with cable count 4 and connector count 4. HW Busters lists the same four plugs as 2 cables, so the PCIe row is stored as 4 plugs on 2 cables at 750 mm. The 16-24AWG range of the 12+4 pin cable includes the thin sideband wires, so the power wire gauge is stored as 16AWG, which APH Networks also states. The AC power cord (1380 mm) is not stored.5Reviewhwbusters.com/psus/be-quiet-dark-power-14-1000w-atx-v3-1-psu-reviewRead 15 October 2026Technical specifications: 2x EPS (2 cables), 1x 12+4 pin (600 W), 4x PCIe 6+2 pin (2 cables), 13x SATA (4 cables), 2x 4-pin Molex (1 cable). Cable table identical to the Cybenetics report. The 12+4 pin cable is rated 600 W.7Reviewaphnetworks.com/reports/be-quiet-dark-power-14-1000w/2Read 15 October 2026Cable list: 1x ATX 20+4-pin 60 cm, 1x 4+4-pin 70 cm, 1x EPS 8-pin 70 cm, 1x 12V-2x6 12+4-pin 60 cm, 2x PCIe 6+2-pin with 2 connectors each, 60 cm to both, 2x SATA with 4 connectors, 1x SATA with 3 connectors, 1x SATA/Molex with 4 connectors, all with 15 cm spacing. The 24-pin, 4+4-pin, EPS and 12V-2x6 cables use 16 AWG wire, the rest 18 AWG. The PCIe length of 60 cm differs from the 750 mm in the Cybenetics report, which is stored.8Retailer pageavadirect.com/DARK-POWER-14-80-PLUS-Titanium-1000W-Fully-Modular-ATX-Power-Supply/Product/19681238Read 15 October 2026Total cables 10.

The page says primary cables are 16-20 AWG and APH Networks says 18 AWG, so gauges are stored only for the 12V-2x6 cable.6Reviewaphnetworks.com/reports/fractal-design-ion-3-gold-1000w/2Read 15 October 2026Page 2: 16 AWG wires on the 12V-2x6 bundle only, everything else 18 AWG. The 12V-2x6 header is 16-pin 600W. Only the 12V-2x6 gauge is stored because KitGuru gives a 16-20 AWG range for the other cables. The APH list of SATA cables disagrees with the maker, so the maker table is used.
