2 x pcie vs 4 x pcie

[jhafner]

Hello;

i've noticed that thermaltake tough power 600w has 48amps rating on 12v rails, and it has 2 x PCI-Express Connector. while thermaltake tough power grand 600w , has 4 x pcie connectors, although it is same amps on the 12v.

so how come same brand and same 12v amps, but different series, one can support one high end graphics card, while the other supports 2 high end graphics card.

Regards.

Hi - for precisely the reason you are asking. They are marketing one (grand)
as SLI/CF ready or it is just an upgrade as the grand is listed as new
in realhardtech's psu database, while there is a plain 600 listed as discntd.

Also, the database claims the grand model has 49a on the +12v
