Some reviews hint that a PSU might be more efficient with 220V input voltage than with 110V. It still gives me the informations I need because I won't use a graphic card with a separated power cable nor will I use more than 2 sata drives, so I suppose my system would not use much of the third 12V rail.ġ) Could a different system be able to draw more amperage from that PSU, or do we have to consider 13.45A the maximum on one 12V rail ?Ģ) For my system, will the 12V2 rail (associated with the EATX12V connector on the motherboard in a 2.2 ATX PSU) be the only one powering both the CPU and the GPU or are the CPU and GPU powered by different 12V rails ?Ī) Do the PCI cards on the mainboard draw their current from the 24pins power connector, from the 4/8pins one or from both ?ī) Is it the same rail that powers the 24pins and 4/8pins motherboard connectors ?ģ) I'm in Europe and voltage here is 220V. I don't know why they didn't test the 12V3 rail to see it's influence on the 2 other 12V rails.
