^^ Hmm is it ? Because in a place like Mumbai there are hardly any power fluctuations, so power surges shouldn be a case of worry, elsewhere its safer to get a UPS to tackle power surges.
^^it is better to be safe than sorry sck .. using a cheap psu is sure to coz problems and remember that you do not get warranty for burnt hardware. so its better to spend some more now and be safe rather than spending all over again for a new rig.
