Is that enough wattage on the 12v rail and overall?
yes, plenty. if you look at the data plates on both PSU's you will notice that the total max wattage of the 12v rails it 384 on both. you could run a quad core and a GTX 560Ti off of either of these PSU's. both are great budget PSU's. I have used many of both to build systems (as well as the Antec EA-380w). Rigth now the XIGMATEK is just the best for the money. next month the prices may flip flop and I'll recommending the Antec.
