However, the above is a more generalized approach to calculating the average wattage, meaning there can be exceptions. Hence, somewhere around 50-60 watts is what you can expect from a typical 2 Molex connector. That means the three pins can deliver up to 4.5 amps of current, which multiplied by 12 volts results in 54 watts. The watt rating can be as high as 120W.Ī standard Molex connector consists of three 12-volt pins, each rated at 1.5 amps.As long as the Molex connector can withstand a moderate power output, it will help power components with a PCI power connection.It offers a much more economical solution than buying a new PSU (Power Supply).Now that you’ve got basic knowledge about the 2 Molex to 8-pin adapter, it is time to know its pros and cons. Pros and Cons of 2 Molex to 8 Pin Adapter So, thanks to the adapter, you don’t have to splurge on a new high-end PSU model right away. And that, in turn, helps power a PCIe video card using a power supply that you can easily categorize as old. Generally, these adapters feature a design that connects to separate rails on different Molex daisy chains. However, that requires your power supply to be rated for powering the GPU. So, it lets you power your GPU from a PSU that lacks a PCI power connection.

2 Molex to 8 Pin Adapter for GPU: What and Why?Īs the name suggests, a 2 Molex to 8 pin adapter is a converter that connects a PCIe graphics card having an 8-pin connector to a PSU having a spare Molex.
