Are there any dangers in running a GTX 660 off the 6-pin PCIe of a separate 550W Corsair PSU (shorting power_on and using switch before and after computer to turn on/off)?
(It is impossible to simply replace the 'active 330w' PSU inside the machine as it uses proprietary connectors for mono power.)
