Does anybody know if you need 26 amps on one rail or can it be spread out among different 12v rails? Right now I have a 500w Ultra power supply with 28 amps on the 12v rail and I was thinking about getting a better quality one with an active pfc, but they have multiple 12v rails.
I would get the neoHE, it states 3 +12v rails but the seasonic S12 design it is based upon lacks per-rail OCP (over-current protection)
NeoHE 550w review, HardwareSecrets.com"]Figure 18: +12 V wires are separated into six wire groups and connected to the PCB as if there were three separated rails.
Figure 19: However they are connected together on the PCB.
The pics in the above link says it all, it is basically a single-rail design and the per-rail current limits can pretty much be ignored.
The raidmax unit has a dual-rail +12v setup with +18A each according to the manufacturer however I could not find a combined +12v wattage, a combined +5/+3.3/+12 wattage nor a +5/+3.3 combined wattage... I would not consider this unit unless it was $40 or less & free w/ the rebate :wink:
