In India, PSU is the most neglected piece of computer. What I have seen over the last 3 years, including my friends, my relatives and the known persons, all of them did not care what kind of PSU and the Case they were getting, they did not even want to talk to about the PSU and the quality of the case (in India, we call it CPU, as taught in our schools). Most of general public in India, is just wholly focused on these 3 things:

• how many GHz the Processor has
• number of cores of the processor
• size of HDD.

I was always the same, shaped by experience but after the poor PSU damaged the controller on my MOBO, I learned a lesson. So I ask, what kind of PSUsand cabinets most people will recommend. Searching the archives, I found praises for Antec, Corsair and Seasonic which are not easy to get in India, even in a Hi-Tech city like Hyderabad, I was unable to find it. what about Cooler Master or an other company ?

and what is the difference between Full tower, Mid Tower and Mini Tower cases

Silentpcreview has a page on PSU fundamentals and a list of recommended power supplies.

I don't know too much about PSU specifics myself. Only that you should buy one that offers enough power for your system and has clean, steady output. A heavy user, such as a dedicated gamer, is going to need more power than a casual desktop user, for example. Noise can be a factor in the decision, as are the kinds and number of connectors the supply offers. A PSU that offers modular cables can be a plus, because too many cables can block air flow and restrict cooling.

Overall I'd think any of the major brands would probably be safe to buy. Just stay away from the real cheap, no-brand stuff.


As for your second question, I believe it's mostly just a matter of size. Full cases usually have 4 or more drive bays, while mid-size generally have 2 or 3. Mini cases are even smaller, and most of them are designed for use with MicroATX motherboards. Other than that, I don't think there's any standardized definition. Silentpcreview discusses cases extensively as well.

I can recommend ASUS and Chieftec as making good quality PSUs, Corsair too if you can ever find them, at least they lasted me a long time without issue. I have a Chieftec case, and it is high quality in that the parts fit well, no rattling of panels or anything, and it's designed well. The other cases I've had were not branded ($ony Vaio cases, who knows who really made them, but they were reasonably good, maybe they were converted ASUS ones by my guess).

I CANNOT recommend Foxconn. I recently bought one, and it failed within 1 month. Maybe it was defectous, but it still means there is a higher chance of getting a low quality PSU from them. Their cases aren't too fancy either, they rattle, and are cheaply made.
