Haha I did that as well but I figured it out before they answered I just needed to put the cap that comes with my PSU the power on self tester I believe its called. Because the PSU isn't hooked up to a MOBO I needed to put that piece on the end of the 24pin mobo connector it was simple haha
Perhaps you should change the "subject" since it has nothing to do with the giant+, LOL!!
Why would I change the subject I was trying to setup the Giant+ miner??? I ended up getting the answer to what I needed through PM with another member actually it can be quite helpful if someone is trying to setup a giant+ and they run into the same problem and not realize they need to jump start the PSU and it is not an issue with the miner itself.
