    1Can I power a GPU with an external power supply?

    Well, as long as you keep track of what’s plugged where. One thing is that you must make sure you turn off the PSU powering the GPU after the main computer shuts down; otherwise, strange things will happen… same as turning it on first before turning on your main computer.

    2Do graphics cards need external power?

    If you’ve connected your graphics card to your PSU, it won’t work. Additional power connectors are needed for the majority of gaming-level graphics cards. If yours does, make sure you connect the PCI-E power cables. Without properly supplied electricity, your graphics card will not work properly.

    In fact, if you don’t connect the PCI-E power cables, your PC will be unable to boot.

    With your graphics card installed and working, you can finish the job by relocating your case’s side panel and inserting your display cable into your new graphics card. Turn on your computer.

    Now is the time to worry about the graphics card’s software.

    This procedure is straightforward if your new graphics card is the same brand as your old card. To get the most recent driver package for your operating system, go to the manufacturer’s website and download the latest driver version for your operating system. Keep in mind that graphics drivers are usually large, about 500MB in size, and that downloading may take some time depending on your Internet connection.

    3Can you use a 6 pin on a 8 pin GPU?

    No you can’t. The GPU has 8 pins and will expect an 8 pin plug. You can convert your 6 pin power into 8 pin power, however, using an adapter like the one shown below. If you do this, be aware that you are sucking more power from the 6 pin rail than it is actually intended to handle.

    4Can you run 2 power supplies one PC?

    If a single unit is unable to cope on its own, a second PSU can be used to divide the load, and it is safe to do so as long as the rail is powered by at least one source. For example, you can use the second PSU to power the hard drives, but the hard drives must be disconnected from the first PSU.

    5Does GTX 1660 Ti need external power?

    Make sure you hook up the card and, of course, any external power connectors such as 6 and/or 8-pin PEG power connectors are included in the PC. Ideally, buy yourself a power source with these PCIe PEG connectors native.

    6Does GTX 1650 need external power?

    Yes, a GTX 1650 super needed an external power cable from the PSU. The 1650 super is a very power efficient card and only needs a single 6-pin power cable to function.

    7Does GTX 1050 need external power?

    MSI GeForce GTX 1050 Ti 4GT OC The Nvidia GeForce GTX 1050 Ti 4GT is a very versatile graphics card, and most of its variations require a separate external power source, but MSI’s Version does not need a dedicated external power source, and all it needs is a 300W PSU.

    8Can I use SATA to power GPU?

    On less powerful GPUs such as GTX 1060 6GB and if there is no other option available, only use SATA connectors. Before leaving the miner, make sure the GPU draws enough electricity via the PCIe x16 slot. As shown below, you can check the power draw by using a PCIe x16 slot and checking sensors.

    9Does a GTX 1050 Ti need a 6 pin connector?

    GTX 1050 Ti doesn’t require a 6 pin connector. It’s fast enough to extract the juice from the PCIE slot itself.

    10Should I use two PCIe cables for GPU?

    You can still use two cables—it works fine, too. However, you won’t get the intended benefit from the setup until you have a power source with more than one 12V rail for a graphics card to draw electricity from. You’ll draw electricity from each rail separately if you plug in two PCIe power cables from such a PSU.

    11Is dual PSU safe?

    Mixing power from two PSUs is risky at best. I’d power the MOBO, the GPUs, and any other card that would be connected to the MOBO from the larger PSU. Fans, HDDs, optical drives, and lighting, among other things, can power the peripherals.

    12Can I use 2 PSU for mining rig?

    Multiple PSUs to one mining machine In the case that your machine needs a 1600W PSU, you can also use two 800W PSUs on the same rig. All you need to do is connect the secondary PSU 24-pin splitter to the 24-pin splitter to do this.

    13How do I connect a second PSU?

    14Does GTX 1060 need external power?

    One 6-pin PCI Express power plugs are required from the system power supply for GeForce GTX 1060 graphics card.

    15Does RTX 3050 require external power?

    Yes, it will all work fine, as they both have a maximum PSU size of 250W. The RTX 3050 will come with an external 6 pin power connector, but the GTX 1050 ti does not need external electricity at all, if I recall correctly.
