I do make adapters that would allow the for the use of 1200i PSUs with Neptunes and most likely Titans, Searing. It just uses two PCIe cables instead of one and that bypasses the over current protection.
Definitely cheaper than buying whole new sets of PSUs. They are in the wild now and no reported issues so far. Check my post history in this thread for a pic.
Please, do tell... bro has 3 of the 1200i's for the 2nd set rrrrrrr
i got some on order from him what the heck it is worth a shot via paypal...otherwise my corsair 1200i is a door stop..even if i never use it ...i can have the deluded piece of mind
that maybe i could use it on the Titan if needed as a 'spare' ..likely I will just get whatever KNC says to get for power supply for the Titan...but the heavier duty adapters can't hurt
probably gonna use it on something someday so what the hey...
(my entire life preparing for stuff that never happens....1) invitation to playboy mansion 2) visit publishing clearing house office 3) seen the BFL monarch in the wild...)
