It's not just about name brand. You'd do well to be mindful of units that are haswell compatible in regards to sleep state issues. I wouldn't buy just any Cooler Master unit by the way. The "V" series is great, though it's definitely going to be on the expensive side where you are.
The number one thing you should never cheap out on is the power supply. Things to note when buying a power supply
• Do extensive research on individual models. Read articles from reputable review sites like JohnnyGuru to get the full story in regards to build quality and load performance. Default rule, if you can't find a reputable review on the unit in question, a good eight out of ten times it's probably not worth buying.
• Cabling options. Not only does it have every connector your system will need, but do you have modular(removable) options. This allows you to limit your cables to only those you need to run the system. Helps make your case look tidier. Little else.
• Efficiency. Meeting the 80+ standard, 99% of units that aren't at least 80+ certified aren't worth it for any system, with some odd exceptions. The goal is to get the highest efficiency rating(within reason per your budget) on a quality unit, while keeping the overall continuous wattage close to the overall amps your system can require under load. This pretty much affects your electric bill more than anything.
• Lastly, aesthetics. More for those that are attempting to match their components for an overall build color theme.
