Please help me find one in a mid range.Also 450W it should be.
when i was searching in the market there were a few 80plus certified budget smps.
some among them were FSP saga II 350(1.5k) and 550w
then there were some from gigabyte superb 460w (2k) and above
some other manufacturers know for better quality are corsair, seasonic and antec.
i would avoid cooler master because there is a lot of confusion among the productline since the cheaper ones will do more harm than benefit you and the pricing is not at all distinguished among the premium ones.
you will need to search them or call folks like smcinternational , prime abgb, deltapage.
ebay could be an option but you need to check some reviews about those specific ones before investing your money in it.
Forgot to mention, check the listings on flipkart.
You can order them from the earlier shops mentioned only if they provide a better deal than fk.
