Im posting a second time today so sorry but I need this question answered quick :) 
Is my Blue Storm II 400 with 400 W power good enough to run a AMD Radeon HD 7770 OC? Please answer quick!

More than enough. Won't leave a lot of room for overclocking CPU depending on the PSU's continuous wattage delivery.

Thank you all! Btw. , I'm not sure how you guys are familiar with it but I would like to play a game called skyrim! Is it possible to play this game on like let's say, high settings with my amd athlon II x3 450? I was able to play it with my Ati radeon hd 5700

EDIT: Also the title is slightly misleading. The gpu im targeting is Sapphire radeon hd 7770 not just radeon hd 7770

i would say with the 7770 you can run vanilla skyrim(no mods or ini tweaks) maxed out at 1080p. as soon as you start tweaking the ini and perf settings or installing mods, the performance will drop through the floor.

In general a 400w PSU should be able to handle an OC'ed Radeon HD 7770. The max power draw will be in the low 90's watts. A stock Radeon HD 7770 maxes out at 83w.

What CPU are you using? AMD CPUs uses more power than Intel CPUs. For example under stress, the FX-8350 uses more than 100w of power than an i5-4670k under full stress.

I use AMD athlon ii x3 450 though when i used something called watt calculator on the internet it told me that my system should draw little more than 300 w
