I can not go more than 375 2 cubes at corsair 1200i more 375
Shut down psu

What the ff
......

I have a corsair 1200i on my computer that would constantly shutdown when the gpu's pulled more than 20A. I have dual water cooled 7990s. I have enabled multi rail OCP in the Corsair and use over clock protection to adjust the rails to allow more than 20A. I am using the Corsair link software to do this. I don't know if there is a way to do this without the software because the default is 20A. So this is probably why more than 2 cubes will shut down the psu. Just my thoughts.

I saw the same thing with my Corsairs, they don't like you to push too many watts over the PCIe connector, I moved to EVGA PSUs..

I dont have the 1200 model but the 760 and 860 ones I have used easily went up to the claimes wattage.

How can they advertise 1200 watts on 12v rail?

Because they do under most circumstances. In fact they now have a 1500w single rail (set to multi-rail by default) PSU...

20 amps is pretty weak for the single they claim, multiple and single virtual option, wth.

.  Even my old Antec HCG750 had dual 40amp.

This power supply is designed to work best in a PC where you can over clock the rails to 40A using the link software.

Notice the slider is all the way to the right to get 40A. You can only activate it by checking OCP otherwise it will default to 20A.

DPS2000-BB.  These PSU's are rock solid.  I run 5 Neptune boxes off each one.  No issues whatsoever. Smiley



What is the power consumption at the wall with this IBM PSU .

I understand that

but it seems counterintuitive to be able to virtual rail multiple rails if you could just have them all draw to 1 main rail???

No wonder the price is so cheap compared to other similar wattage units.

The AX series Corsairs aren't cheap. They're some of the most expensive PSUs on the market.

I just whipped this little number up for possible use on a Neptune.

I am considering upping it to 16AWG and HCS pins but only if there is demand for it.



Well I'll definately take 10 of the upgraded ones, if it goes ahead I'll see if any other UK users want them so you can just do 1 shipment.

Question to the "single rail/Multi rail" specialists:

I have a 1600 Lepa (which is multi rail) and this one has 6 VGA plugs (so 6 cables).  What I want to do is connect 2 cables to one Neptune-box (I solder one additional PCE-plug on the box), so in total 6 cables to 3 boxes.

My question now: does it matter that I join two multi-rail outputs to one ?? (in essence connecting one +12 multi to the other +12 multi rail).
