Splitter for dual graphics cards
This Monoprice BX0019-1183X splitter cable adapts a single CPU 8-pin female connector from the power supply into two PCIe 8-pin (6+2) male connectors for graphics cards. It is intended for builders adding a second GPU to a system that only provides one CPU power lead. The two-pack supplies a spare cable for a second build or replacement.
Practical limits of the CPU-to-PCIe interface
The cable draws auxiliary power from the CPU 8-pin rail, so total graphics power is capped by that rail and the 18 AWG conductors rated for 57 volts. It cannot deliver the full current of a dedicated PCIe power cable, making it unsuitable for high-wattage cards or multi-GPU mining rigs. Using it on a motherboard header instead of a GPU will cause damage.
23 cm length and 18 AWG gauge
At 23 cm including connectors, the cable only reaches components close to the power supply, limiting routing options in larger cases. The 18 AWG wire sets the safe current ceiling, so buyers must verify their graphics cards stay within that limit before purchasing.

Questions about this item
Should I get the 2-pack or a single cable for my dual-GPU build?
The 2-pack gives you two identical splitter cables so each graphics card can draw from its own CPU 8-pin rail, avoiding daisy-chaining on one rail.
What does the 57 V rating mean when the PSU only puts out 12 V on the CPU 8-pin?
The 57 V figure is the insulation voltage limit of the 18 AWG wires; the 12 V from the PSU is well within that limit.
Does the CPU 8-pin to dual PCIe 8-pin (6+2) splitter follow the ATX 3.0 or PCIe 5.0 power standard?
This cable uses the standard CPU 8-pin and PCIe 8-pin (6+2) pinouts; it does not implement the 12VHPWR connector defined by newer specifications.
