Introduction
Very few of us realise the importance of a good SMPS.Infact i must say that the SMPS is one of the core components necessary for a healthy system.
Nowadays or should i say since the days of Intel P4 and AMD Athlon XP,we have started experiencing 300 watt SMPS.
Earlier we had 230 watt SMPS.
Many of you must have realised that nowadays many peripherals like CD-Writer,DVD-Roms...have become quite cheap.This directly implies that more and more people are opting for it.
Also it is noteworthy that fast CPUs are rapidly becoming affordable.
The point i am trying to make is that when you increase no. of components like CD-Writers in your computer and use faster CPUs which consume more power,you instantly start feeling the scarcity of power supplied by your old SMPS,mostly a 230 watt one.
What is surprising is that nowadays we feel that 300 watt is also not enough.Times are changing fast my dear friends.
Anyways i will cut the crap and get down to the review straight away.

Conclusion
From the above information and testing,i must say that this SMPS delivers what it is supposed to.
Very few times have i come across such a stable product even under heavy load.
The actual voltage values when tested after putting full load were pretty impressive.
The Voltages remained very stable without much fluctuations and tried to remain around the theoritical values.
It should be noted that all the voltage values were above the rated ones and never did they drop below them,which is pretty good i must say.
Now comes the main issue,Price.
What can i say,it is sweet as the product itself.
This product is Priced at a modest Rs. 1850/- [Inclusive of all]
Also this product comes with a 1 Year Warranty.
Finally i must say that we have a good product with a modest price available in India which is affordable to everyone. Overall a good product.
