check this table first. http://www.thinkdigit.com/forum/graphic-cards/142679-gpu-psu-tables.html

dont ignore the min. wattage requirements. your rig will go numb when its under load if enough power is not supplied to the system.

coming to the options u gave. 7770 is the best bet for your PSU.

As per PSU calculator (coolermaster,extreme psu caculator, outervision.com) my system maxmimum requirement is 375 watt for HD 6870. Is it wrong ?
I don't have HDD, BR/DVD writter, PCIE card in this system, but installed 1x1=1 SSD, 2X1=2 120mm exhaust fan, 1x1=1 140mm inlet fan. All in default sys, no overclock.
I prefer 7770 as low- watt, temp & Dx=11.1 pcie 3.0 but performance= ?
Also driver problem at present & discovered blurry textures by tom's hardwere

You PSU is definitely good enough for a HD7770. But If you are opting for 6870 or 560 then it may put it on its edge under load.
