i've faced no problems with it and have been using it fr about 6 months nw.. ppl who have rated it 1 stat let me know what is the problem ur facing

Don't buy any PSU from Cooler master. All of them are crap.

I have RMA'ed 4 (1 CM extreme 2 625W, 3 Thunder 600W and 700W PSU) and I don't have a working one yet.

Better go with brandless PSUs but not these.

It doesn't even deserve to be listed for sale. Not even worth a single star.

Srihari@ What's your System specs? This PSU will not last you longer. It ran with issues for 6-7 months and dead all of a sudden.

I applied with Sabertooth 990FX Mobo + 12 GB RAM + LG DVD RW + AMD 8120 3.11GHz + 500 GB Cavier Blue, 1 TB Seagate Cavier Green, 1TB Seagate + 120mm CM Air Flow + 120mm CM MasterFlow + Nvidia 440 GT 2GB

In their website it is written as 3 yrs international warranty....
here is the link http://www.coolermaster.in/product.php?product_id=6728
but here it is only 2yrs...
dont know why..!
Good option if u r looking for a reasonable PSU (+12v x 2)
