my neptune crash down when i put 400 mhz and more\
whst to do
i had 2 corsair 1200 i
but i think is awful psu fina;
Can u run 2 cubes on one 1200i at 475 MHz ?
If this works just get a new smaller PSU for 1 cube.
Can u run 3 cubes on one 1200i IF THE OTHER ONE IS OFF?
You might be starving your AC circuit.
If you have a HEAVY DUTY 12/3 extension cord try one PSU on a different outlet.
copper house wire can corrode if the wall outlet screws are not tightened properly
(thats a hard one to troubleshoot)
You might try a housefan on the PSUs?
With Corsair it has been suggested to use only the DOUBLE PCIe cables
but
USE ONLY THE FIRST(closest to PSU) OF the 2 PCIe CONNECTORS
16AWG to first connector and 18AWG to second
I know as fact my Corsair single PCIe cables are only 18AWG
(lower is better for AWG)
I have AX760's but the replacement cables are same part numbers
I ran 2 cubes on 1 760 briefly 10-15 minutes hashing @ 475 MHz
Try possible solutions that do not involve spending lots of money FIRST.
Else throw money at bigger PSU's
Thx again u27 for that Corsair wire gauge detail!
YMMV
EDIT
Run them 2 at a time and identify WATT for each cube
Try the 3 lowest watt cubes on one PSU
Try same 3 lowest watt on other PSU
Subdivide and conquor!
