2. Adapter cable is not recommended, please use direct module cable.

Reason A: Adapter cable + power supply original cable, if the length of each cable is different, the current will mainly pass through the short one (the one with less resistance), which will cause overload.

Reason B: Adapter cable + power supply original cable, this increases the number of connectors, which increases the number of contacts and the risk of defective connections.

Reason C: Regardless of 1 to 2, 1 to 3, or 1 to 4 adapter cables, it does not increase the number of wires and increase the cross-sectional area of the copper cores, because only one wire can be crimped to the end terminal of the graphics card. The more adapters there are, the more risk there is.
