Power Supply + Fans

[BSOD]

I'm planning to buy a new power supply as my current one(a VIP 450W) is acting up. I think I will need something from a reputed company, I'm tired of all these crappy PSUs. I'm also gonna buy some new fans(both 120mm and 80mm) for Zebronics Peace(my current chassis). Also, anyone know if its possible to replace the fan at the top(the one with the button) in Peace?
I might buy a new chassis in the near future, any suggestions?
PSU budget: 2.5k
Fan: 1k
Thanks.
