tangentray said:you can always go for the cabby if you like it. but think twice before you choose an smps. the whole system depends on it. if it is incapable of supplying right amount of power then you risk loosing the whole rig mobo, cpu, gfx card ... everything. the generic psu-s are risky, so we reccomend a aftermarket psu even if it is not high end. i guess you can get dependable psu-s ~1.5K. tell ur dealer to take out the psu from the iball cabby and deduct some amount (~500 if u are a good haggler) from the cabby price, invest that in the better smps. it will cost u ~1k more but u will have peace.
I have another query..

Is it possible that because of some fault in the SMPS my PC goes off for 2 secs and restarts on it own. Sometimes when it stops i just touch the CPU fan and it starts again. Can this issue be linked to the power supply????
If yes then i'd just like to change my Mercury power supply ( i i just read on its box that it is 300 W) and see if the system works fine. Then no need to upgrade also.

My usage is for internet & MS office .. and when my PC is working it has sufficient power to handle everything. So i'd like to test with a new power supply (suggest models plz for p-iv 2.8 mhz, intel 865gbf) ... In case if problems continue and I upgrade then will i be able to use the same new power supply in the new PC ???
