    I have yet to try the cable itself yet, but the customer service was great enough that I thought I would leave a review already. Can't wait to get it!

    Great to work with ModDIY's customer service, who answered my question promptly and they are going to make some custom PCI-E power adapters for us. If you don't see it on their website, then be sure to contact them at support@moddiy.com - they probably can make it for you!

    This cable neatly replaces the triple 8-pin PCI-E cables connecting to a 12VHPWR adapter. Tidies up what was an ugly mess of cables at the bottom of my case.

    As others have said - took a couple of weeks to arrive from Hong Kong, but it was well worth the wait!
