Review on Splitter Cablexpert PCI-E (8pin) - 2хMolex (CC-PSU-81), 0.15 m, black/yellow by Stanisaw Lem ᠌

Ordered quickly, received quickly. Used to connect modern video cards with 8 pin power supply to old computer power supplies with MOLEX (4 pin) connectors. After connecting this adapter under load, observe its temperature to see if its wires and the connector itself (chip) heat up. If it heats up and heats up strongly, then you need to insert the "chip" more tightly or replace this adapter with another one. If none of the above helped, then it is worth replacing the power supply itself with a new one with the right connector that is known to be on it.
