Can a low-end cheap power supply REALLY have a dedicated 6 pin pci-e power connector? because i just got one 600w psu that has one...is that possible? what would then be its purpose because it would unlikely be used for any reason whatsoever?i've checked other 600w PSU's and they don't have one! even 500w coolermasters and aerocools don't have one! also it has 10 amps on the 12v rail... And can it power good graphics cards like the 560ti or 550ti at PEAK usage? I'M CONFUSED!
The psu you refer to is probably over rated at 600 watts...as for the pcie connector..they just include that as selling point to people who dont know any better. With 10 amps on the 12v rail there is no way it will power a 560Ti
