Plz tell me where the rest of the 300W will go i am a noob so plz don't mind.
Why then it is sli certified for the sake of branding i think the card consumption is low even at peak as compared to previous generation cards then how it got certified?
Or it is certified for only mid range cards.
certified is more of a marketing term. while the PSU meets nvidia (or AMD with crossfire) standards for SLI (more then one PCI-E connector) you really can't tell what specific cards it can power without doing a bit of homework on independent review sites like techpowerup, techspot, anandtech, guru3d, etc.,http://hothardware.com/News/NVIDIA-SLI-Certification-Program/
