I have seen too many melted molex plugs to recommend splitting any power supply output. Even the HDD plug to PCIe power plug adapters are overloading the HDD molex well before at the capacity of the PCIe end.

 

Really power distribution inside PCs is terrible and its amazing that more dont go up in smoke.

Hey richms, thanks for the reply.

I can see where you're coming from,

I've done a bit more reading on my PSU and the GPU, and the splitting options etc (I didn't know if splitting the pci-e is a thing),

The GPU draw is 170watts and my PSU suggests it's 1 6pin pci-e has a max wattage of 170watts, so I'm going to take a chance on this one given it's an old system as it is and I can keep an eye on it :)

I have committed many such crimes without melted plugs, chances are it'll work ok. Sometimes there is no other option such as with proprietary systems like HP workstations.

 

If you have an older system you might have multiple 12v rails. Those adapters usually have 2x molex connectors. Try to connect each molex connector to a different rail if that is an option.
