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 retail box table of the 850W unit (photo in the XtremeHardware review), the installation guide and an earlier copy of this page in that review give 610, 650, 750, 720 and 450 mm and two 4-SATA cables plus one 2-SATA + 2-Molex cable, on 5 CPU|PCIe and 3 SATA|Molex sockets, which matches the Phanteks product render. The box and guide values are stored and the conflict with the current page text is noted for review. The 12V-2x6 cable is 450W on the page, the box and the review, while retailers print 600W.4Owner's manualphanteks.com/manuals/AMP_GH_Installation_Guide_v1.1.pdfRead 16 October 2026Cable table for the whole GH range: motherboard 24-pin 610 mm, CPU 4+4-pin 650 mm, PCIe 6+2-pin 750 mm, 12V-2x6 720 mm, SATA 4 plugs 450 mm with 150 mm spacing, SATA and Molex 2 and 2 plugs 450 mm.

Mixed5Reviewtomshardware.com/pc-components/power-supplies/cooler-master-mwe-gold-850-v3-power-supply-reviewRead 15 October 2026All-black cables, most flat and ribbon-like without sleeving. The 12+4 pin cable has nylon sleeving and a 90-degree connector.

Sleeved9Reviewxtremehardware.com/recensioni/14837-phanteks-amp-gh-850-recensioneRead 16 October 2026Text: every included cable has individually sleeved wires with a textured rubber coating that imitates a paracord sleeve. The bundle photo shows round, individually sleeved wires and no flat ribbon cables. The maker calls them individually textured cables. Stored as sleeved because none of flat, embossed or mixed fits.

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.
