RKelley Posted October 28, 2016 Share Posted October 28, 2016 Greetings all, After reading tons of threads on this site (awesome info!), I ordered an Akitio Thunder2 box with a 2M thunderbolt cable. I have a spare R9-290X card which requires 1x 6Pin and 1x 8Pin connectors to use as a test. From what I have read, the 6-pin pulls 75W and the 8-pin pulls 150W. Thus, I need a 235W PSU (225 for video card and 10W for Akitio unit). Is this correct? If so, is there an external "brick" I can use to power this setup? While I do have an normal PC PSU, I would much prefer to use one of the brick units (Dell DA-2, etc) to keep everything looking good. Once everything is running well, my son is going to CAD a custom box and make it in his fab lab. Quote Link to comment Share on other sites More sharing options...

Just because a connector is rated for a certain power doesn't mean it will utilise it. Go find the actual TDP of the specific card itself.

You might be able to get away with using a single Dell DA-2 if you're willing to undervolt/underclock the card to lower its power requirements. Otherwise, you'll have to strap two DA-2's together - At which point it might just be easier to use a regular ATX PSU. I managed to power a 244W GTX580 using a 216W 12V rail after undervolting it.
