![]() This Cable will provide up to 2 x 36Watts Watts via the 2 x Molex connectors to 8pin and will draw up to 75 Watt from the PCI Express x16 Slot. Suitable for connecting PCIe Cards from NVIDIA and ATI with an older Power Supply which does not have 6-pin PCIe Connector. This cable converts 2 x 4-pin Molex connections into 1 x 8-pin PCI-E power connections. PCI-E Black 8 pin to 2 x Molex Power Converter Cable – Graphics Card Adapter Power Cable to older power supplies Cable used to convert older generation power supplies for newer graphics cards. But there’s a high chance the components, PSU, GPU, and Molex will get damaged along the way.2X Molex To 8 Pin Power Cable For Graphics CardĢX Molex To 8 Pin Power Cable For Graphics Card Description If the power supply has what it takes, it may run the GPU with minor hiccups. Whether you can use 2 Molex to 8 pin converters for GPU eventually boils down to what your PSU is capable of. Yet, if you somehow manage to run the system, the Molex might end up melting due to excessive overload. Even two Molex connectors used together are no match for a single PCIe power cable. Simply put, 2 Molex to 8 pin adapters are not suitable for power-intensive tasks like mining or heavy gaming. There is a lot of option out there, and here is a useful and handy one. So, using a 2 Molex to 8 pin for GPU is doable, but calling it unsafe seems more logical. In other words, 2 Molex to 6 pin adapters are safer since 8 pin PCIe power connectors are found on high-end GPUs. Is 2 Molex to 8 Pin Safe for GPUĪlthough it is theoretically safe to use 2 Molex to 8 pin adapters, in reality, it strains the capacity of the Molex. And as long as the PSU runs fine, you don’t have much to worry about. Furthermore, your PSU has to have the ability to supply adequate power to the component, GPU, in this case. However, the adapter, male or female, must have pins that resemble the exact pin specifications of the actual connector. More importantly, the outcome is pretty much the same as you would get from plugging the PCIe cable itself. Yet, a 2 Molex to 8 pin adapter is perfectly safe as an alternative in case you haven’t got the correct PCIe cable nearby. Sooner or later, you have to upgrade the connection or the PSU itself. Using 2 Molex to 8 pin adapters for too long is not a good practice. Therefore, there’s always the risk of burning the Molex connector, or even worse, damaging the GPU and power supply. If you’ve got a power-hungry GPU, this setup may not work, for a Molex can handle up to 54 watts. And comparing that to what Molex connectors can withstand, you can get an idea of whether to use it or not. ![]() But still, it’s kind of a hit-or-miss thing as PSU specifications don’t usually state how much power it delivers through Molex connectors.īesides, you’ll require at least some level of knowledge regarding the maximum power your GPU will consume. Having said that, you will most likely need more than one converter if your GPU is not compatible with the current PSU connectors. However, you can still run your graphics card with the help of a ‘2 Molex to 8 pins’ converter. As you might already know, a PCIe power connector with 6 or 8 pins is the default for GPUs. Can I Use Molex to Power GPU?Īlthough using a Molex to power a riser does not have that big of an impact, it isn’t the best method for GPUs. And the other part, the more important one, is if it is actually safe to do that. One is whether or not it is possible to use 2 Molex to 8-pin for GPU. Thus, the amount of power you can expect a Molex to supply is around the 54-watt mark. And if you calculate the wattage, 4.5 amps multiplied by 12 volts will give 54 watts. ![]() Together, the pins measure a total of 4.5 amps. Generally, there are three 12-volt pins found on a standard Molex connector, each capable of delivering 1.5 amps.
