ok cheers !
thanks for patience with a noob like me.
now setting the 2nd PSU will be a piece of cake
First, congrats on your foray into mining... it's addictive.
Each S3 requires a minimum of 2 PCI-e connectors. The RM1000 has 8, so you're good to go. The PSU has 6 PCI-e connection points which are clearly labeled. You'll also have 6 PCI-e cables, 2 of which will have a "double" end giving you the total of 8 available connections. You plug the 8-pin end into the PSU, and the 6-pin end into your S3 (the 6-pin end is actually a 6+2 setup... pull the "2" away and plug the 6 into the S3). Make sure you plug 1 PCI-e connector into each side of the S3... don't plug them both into the same side.
For the paper clip, go here:
