Mine was cheaper sir, i guess because i haggled, there were lots of people there when i last visited. Warranty will depends on whether they do in store exchange/RMA or you need to send it in yourself. I had a few PSUs in Sim Lim where they never called back about the mother boards or PSUs and i had to chase, they of course told me that the person in charge has left so my RMA PSUs etc are still somewhere out there.
