This thread is only meant for new members of this forum who tend to repeatedly ask questions about PSU. This is a generic information thread, nothing more and nothing less. My intention of starting this thread is to end these circular discussions. PSU is often the most ignored part of your computer system. But in reality, it is the most important.
A typical Indian buyer is most likely to buy an el-cheapo sasta
inefficient and highly overrated PSU with extremely poor voltage regulation, noise and ripple. And one day when that PSU will die, it will take your system along with it. There is a reason why a good 500w PSU tends to cost in excess of Rs. 3000 and a crap desi 500w PSU will cost only Rs. 700. So, if you're thinking "I have a 500w PSU and IT IS AWESOME AND CAN RUN ANYTHING." You might very well be living in a world of delusion.
Before continuing reading this post, I strongly suggest reading the following post by The Sorcerer: Basic guide for the right power supply
This thread will only deal with companies you should AVOID at every cost. Not with whether X company is better than Y.
So, which are the good PSU companies?
- Cooler Master: Avoid Elite Power, Extreme Power Plus, old GX series. They all are bad. Good ones are Real Power Pro and Silent Pro. But 99.5%, your local shop will be having Extreme Power Plus and it is not value-for-money since much better alternatives are around. So..don't get fooled by the brand name, concentrate on the model name.
Extreme Power Plus is said to be discontinued now. GX series have seen a new revision and change of OEM.

- and stay away from every other local desi brand. You know more? Post in this thread. I want this list to be as long as it can be.
In no particular order these are some good names, and they have had bad models. Seasonic, Corsair, Tagan, Antec, Silverstone, Glacialtech, FSP, XFX and the likes.
No one is really good. This is all about being specific and to the point with the model name. Even the above mentioned 'good' companies have bad units here and there in their portfolio, but I don't think people on this forum will recommend those to you. Even if someone does, he'll be corrected. The important thing is, you should know what to avoid - atleast be in a frame of mind to know which ones are good and which are not. Go to your shop. Note down the exact model number / revision and research on the Internet.
I repeat, no "brand" can be "termed" as "good" - so, please don't go for the generalisation. Always research for a particular model.
My local computer dealer says that he puts iBall 500w PSU (or some other) in every computer and they work fine?? What should I do?
well, your local computer dealer is a moron. Not exactly a moron, but highly misinformed.
Not his mistake though. His job is to sell and that's all he knows. The state of intelligence of Indian computer dealers and Indian general public is well known. Don't believe them. Their knowledge is limited and myopic.
Here's an example - *Captian Doomz* Click here.
Also, there isn't any need of blindly believing what people tell you on this forum or some other forum. There are many portals where you can ask questions and know more. Do your own research.
It takes effort, but it's worth it. Social networking websites like Twitter, Facebook and Orkut aren't the best places to ask questions. There are very few right guys out there.
I don't have any good PSU available at my dealer. What should I do?
Shop online unless you think India is still living in 1980. There are various payment methods - Cash deposit/Demand Draft, Net banking and Debit/Credit Card. These vary from dealer to dealer anyways. It is your job - don't expect the forum members to spoon feed you. And make sure that the dealer gives you a proper bill.
One small advice - PROVIDE FULL AND EXACT INFO.
If you are creating a thread asking for a new graphic card you HAVE to mention the EXACT company, make and model of your Power Supply (SMPS).
Exact specifications of your system would be helpful too.
"i have a 400w power supply" --- this is wrong.
"i have a 400w power supply from Corsair" --- this is again wrong.
"i have Corsair CX400 power supply" --- this is right.
[S]This thread isn't for the well-informed. It is for someone who is new. I know I have generalised, but it is for the good, not for the bad. Those who are aware of the Indian scenario, will completely agree with me. Feel free to PM me.[/S]
