I'm done with the backside of the 24pin, and I can't tell you what a relief it is to check that off my list. Those of you with dual PSU's know what I'm talking about. For my dual PSU setup, I've been shorting a couple of wires on the second PSU to make it run without having the 24pin plugged in. That works fine...but the annoying part is that all the fans plugged into this one would continue to run even when the computer was shut down. And they run at 100%...since there is no software running to spin them more slowly. Since both GTX690's are powered by the second PSU....these two monsters would start spinning at 100% as soon as the computer shut down. Sounded like a vacuum cleaner! I would always make a mad dash to flip the PSU switch in the back of the unit off to get them to power down....so that I didn't wake up any neighbors. And...then would have to remember to switch it back on when I wanted to boot back up.
No more! With this crazy looking little cable...I've tied those two wires on the second PSU into the same two wires on the first PSU. So now...I can leave the PSU switch on for both PSU's...but when I shut down the computer everything turns off. And when I boot backup....everything comes on. I've missed that.
Here is a look at this crazy little cable. Since the 24pin for a Corsair AX850 has two plugs on the PSU side...I end up with 3 plugs on the PSU side so I can tie into the second PSU. I've elected to take these shots from a different location in my house than I normally do....so that I can spread a little Christmas cheer while updating my build log:
Here's what it looks like in the case.....
It's impossible to keep a pattern at all when the wires have to cross over each other to get to the right spot on the PSU connection. Corsair takes the 24 pins from the motherboard side, and spreads them over a 18 pin plug and a 10 pin plug. I would pay $100 extra for a PSU that simply had a 24pin connection on the PSU side that ran wire for wire to the motherboard side. Listen up Corsair!
But that is the reason I went with a pure 24 pin extension for the longest part of the cord. It stays looking neat...and the mess created when moving from 1 24 pin connector..... to 28 pins spread accross two connectors....can be largely hidden.
Next up is that black cable on the bottom in the last pic. I'm going to run a power connection from the bottom PSU to the cold cathode inverter and then to a SATA power connection for the pedestal. More to come!
