Will this power supply work with my AMD HD 7770 1gb GPU?

Solution
Yes, that would be a much, much better choice. It's not a top shelf PSU but it's fairly reliable and is not likely to do what you saw in the video. I realize selection is likely limited where you are and prices are high, so it would work well for you.
Sure, if you don't want your computer anymore. The PSU is the most important component in the system. If you had to go cheap on every other piece of hardware it would be better than going cheap on the PSU. You want something from Seasonic, XFX, EVGA, Superflower, Enermax or at least a CX series Corsair. Anything from Tier 3 or higher and 400-450w should be plenty at the following link:
