Just received my Titan :

PSU : corsair AX 1500i
cannot run it above 250 Mhz (def : 300) because the PSU shutdown in protection mode.

at 250 Mhz, this shit draw 1100 watts

the hashrate vary between 150 & 250 mh/s

some times it stop mining, I just need to reboot it. Like that :

ps : if some one know where to buy pci-e Y cable for the titan, please tell me, I don't want to wait month before knc deliver them.
ps2 : the miner is pointed here : http://clevermining.com/users/13BeJG5DuNgsY2aMDCqEwtbDrYfRQryjip

You can disable OCP on AX1500i...

From Corsair Forum: http://www.corsair.com/en-us/blog/2014/may/setting-up-ocp-on-the-ax1500i

"The other method that can be used is to turn off the OCP altogether. To do this, you must check all of the boxes for OCP and then uncheck them. After no more than 15 seconds, OCP will be disabled on the AX1500i power supply."

anybody have any idea if this also works on the corsair 1200i? (am looking now on their site)

The Corsair AX1200i comes with software that allows you to configure anything, including switching off the Over Current Protection (OCP). The problem is that this requires use of a special cable that connects to USB header pins on a motherboard (this makes sense, the PSU is designed to be inside a computer).

It is a lot of hassle to run a naked motherboard for the purpose of running the Corsair software, so the easiest solution is to effectively bypass the OCP using PCIe 2-to-1 Y power cables. This halves the current draw on each PCIe port on the PSU.
