What I like about MSI Power Edition video cards is the same thing I like about Hawk and Lightning series video cards. They're just more fun than your typical design. Combined with MSI Afterburner, the larger choice of voltage options make for a video card that you can push much further than others.
Moving away from just the overclocking side of things, you've also got the fan configuration options which are cool and really easy to setup. I didn't even have to read the manual to figure out the options.
AMD's Radeon HD 7770 is still far from a model that we're in love with like the other HD 7000 offerings that sit above it, but it's nice to see companies starting to do something interesting and creative with the HD 7700 series. If there was ever going to be a HD 7770 that took our interest it would've been from MSI and it would've been part of something like the Power Edition series.
With an MSRP set at around $149 as well, this is a good price point for a video card that offers this kind of feature set. Combined with being part of the new HD 7000 series, this is one of the, if not, the best HD 7770 to buy, that we've looked at so far. Before the AMD price drop I think this video card would've come in closer to the $179 - $189 mark and that would've just been too expensive.
The only downfall for the video card is the noise levels we got with the two fan setup. From a pure number stand point the video card is quite loud and while it's noticeable more audible at idle compared to other video cards also at idle, the load levels aren't too bad at all. Inside a case I think you'd find the video card fairly quiet. Of course there's always the option for the other fan configurations as well, we did opt for the one that lets the video card run the coolest, which comes at the cost of more noise.
If you're looking to spend around that mid $100 mark, want to get in on the AMD Radeon HD 7000 series and are happy to fire up MSI Afterburner to unleash the most potential, the MSI HD 7770 Power Edition is a great offering.
