howz it goin. a friend bought me this psu for my b'day and i don't feel like spending money on a different psu. But, is this psu good enough for overclock a gtx 560 non-ti (asus oc verison) to 950mhz and perhaps a intel core i7 2600k to 4ghz? i got basic things, on dvd-drive, a gigabyte z68xp-ud3 mobo, 2 sticks of 4gb kingston hyperx ram (2x4gb) and some other things. is it enough and most importantly, is it safe?
