for Mac Pro GPU Power Cable 2X Mini 6 Pin to 8 Pin PCIe for GTX/RX Upgrade

• 🔹 MINI 6-PIN, NOT STANDARD 6-PIN — VERIFY BEFORE ORDERING ⚠️ ⚠️ The two input connectors are mini 6-pin — Apple‘s proprietary small connector found only on Mac Pro logic boards. They are NOT standard PCIe 6-pin connectors. ⚠️ Do NOT use this cable with non-Mac Pro motherboards or standard 6-pin PCIe ports. Doing so WILL burn or damage your motherboard and graphics card. This cable is designed exclusively for Mac Pro and Power Mac G5.
• 🔹 BOTH MINI 6-PIN ENDS MUST BE CONNECTED — 300W TOTAL ⚠️ Your Mac Pro 4,1/5,1 has TWO mini 6-pin auxiliary power ports, each rated for 150W. ⚠️ Both mini 6-pin ends MUST be plugged into the motherboard. Using only one mini 6-pin end will overload a single power rail and burn the motherboard. Two 6-pin ports together provide 300W — enough for most 8-pin graphics cards. Plus 75W from the PCIe slot = ~375W total available.
• 🔹 COMPATIBLE WITH ALL MAC PRO MODELS 2006–2012 Designed for Power Mac G5 and all Mac Pro models: (1,1), (2,1), (3,1), (4,1), (5,1) — or (2006), (2007), (2008), (2009), (2010), (2012). Works with MacPro1,1 through MacPro5,1 logic boards. ⚠️ NOT compatible with Mac Pro 2013 (6,1) or 2019 (7,1) — those use different power connectors.
• 🔹 38CM LENGTH — DUAL CABLE DESIGN FOR FLEXIBLE ROUTING Each mini 6-pin cable is 38cm (15 inch) long — measured from the mini 6-pin connector to the 8-pin PCIe connector. The dual-cable design allows each mini 6-pin end to reach its respective port on the Mac Pro logic board independently, accommodating different port positions across model generations.
• 🔹 18AWG TINNED COPPER — 8 PIN (6+2) DETACHABLE Built with 18AWG tin-coated copper wire for stable power delivery. The 8-pin output is a 8-pin (6+2) connector — the 2-pin section can be detached to create a standard 6-pin connector for graphics cards that only require 6-pin power. Latching connectors ensure secure connection.
• ⚠️ IMPORTANT NOTES: Mini 6-pin, NOT standard 6-pin. Do NOT use with non-Mac Pro devices. Both mini 6-pin ends MUST be connected. Using only one will burn the motherboard. Only for Power Mac G5 and Mac Pro (1,1)-(5,1) / 2006-2012. NOT for Mac Pro 2013 (6,1) or 2019 (7,1). Turn off PC power and unplug before installation.
