Please read the entire description before purchasing.Please contact me before asking for a return.  It's likely that I can help you get this card working.  I get penalized for high "item not as described rates".  I'm telling you up front that this card may not work out of the box and you may need to change bios settings, etc. to get it to work.These cards are RTX3060 mobile chipsets in a desktop form factor.  As such, they have some limitations and priced accordingly.  These cards work great on Windows and play all major game titles.  They use very little power (55w on average).  There are two 8 pin power connectors and they come with a splitter that reduces it to one 6 pin power connector.  There are 4 graphics ports, however only the HDMI port functions using NVidia drivers.  The DP ports do not generate a display.  This card can be the sole card in the computer and it will boot.  Some motherboards require setting the display boot priority to legacy mode.  There are production NVidia drivers available on github.  I will provide you the link (ebay doesn't let you embed links to github in listings).  It's under "arutar/FrankenDriver" if you want to search it. There is also a relatively simply process to create your own NVidia driver from any version you want if you don't want to use that one.  I have personally tested these cards on over 20 popular games and the performance is comparable to a standard 3060ti.  These cards require UEFI boot and will not work with Windows 7.  These cards were used for mining ETH for about 9 months.  They never exceeded 40c because the mobile cards run super low power and super cool.  I have been using one in my personal desktop for the last year with no issues.  These will be shipped with the power splitter and a link to the drivers which I will also email you.  If it doesnt work for any reason you can return under the standard ebay policy within 30 days.  This will be shipped USPS "ground" which is the new version of priority mail regional.  Most destinations are 2 to 3 days for delivery.  Please feel free to ask any questions regarding compatibility.  If I am able I will test the card on software that you are considering using it for.
