Hello, I want to power my Asus PRIME GeForce RTX 5060 Ti 16GB graphics card, I need an 8-pin PCI-E cable but why does my 6+2 cable have a pin missing on one side, can I still use it?

Hello,
Test the 6+2 cable to see if the card powers on.
If nothing happens, you will need an 8-pin PCI-E cable.
Have a nice day.
Hello
You have a high-end power supply, it has at least 4 compatible PCI-Express connectors, you need to refer to the description provided by MSI to connect them, or possibly on the MSI website.
Hello,
Thank you for your feedback, so I powered it on and it worked well; I'm sharing the information that clarified things for me.
-
The 8-pin PCI-E connectors for graphics cards are always organized as 3 wires for 12 V and 5 grounds (GND).
-
Some cable manufacturers do not install all the metal pins in the connector, especially for the grounds, because electrically, it's not necessary if the other wires can handle the current.
-
The “hole” you see is probably a vacant ground position, and it is perfectly normal on many official cables.
-
As long as it's really a dedicated PCI-E cable coming from your power supply (and not an extension cable or a SATA/Molex adapter), you can use it without any problem.
⚠️ However, absolutely check :
-
That the cable is coming directly from the power supply (not a dubious adapter).
-
That it’s a PCI-E connector and not an EPS CPU (they look similar, but the keying is different).
-
That your power supply has the necessary wattage for an RTX 5060 Ti 16 GB (at least 550-600 W with a good 12 V rail).
