or you can remove the elec current limit with corsair-link software.
That you can, but it resets every time you power up so it's a pain for multi PSU. Also the Corsair Link has a MB USB connector to you will need an adapter or an open PC to hook it up. You can set each virtual rail to 40A which is more than enough for 500Mhz Neptune.
If you scroll up there are a number of cables available which allow you to connect each cube to two virtual rails thus doubling the default 20A setting.
Frankly the PSU is excellent and KfC screwed up their design using a single PCI-e; a PSU
should shut down if you try to pull upwards of 20A over a PCI-e cable! I will sleep easier knowing there is some level of 12v over current protection for my Neppy.

true! my 850w PSU does not shut down, but the PCI-e cables become very hot (especially near the PSU connector). I am worried that such huge current will make the cable/connector melted.
I just come across an idea: many graphic cards have a 6pin-to-double-molex cable.

If we have two molex cable connecting to the PSU, and then connect to this cable, will it solve the problem?
