This thread made me stormed into many confusion...
Firstly, is it possible to have two SMPS connected on a single Rig...
The thing is SMPS need to be get started to give Power supply, and it only get start after we Push the Start button of Cabinet....
If you need to surpass this situation then you need to do some "Karagiri" (work out on it)
It may be done by cutting the few wire from the main power connector of the PSU ( one which is used to give power to mobo ie 24/20 pin connector) then joint few wire so that it remains always on...even if CPU is off which is been powered by other SMPS.
@ NikhilVerma
Firstly 400 watt Frontech in real sense dont deliver 400 watt. Its lesser than 350watt actual
Secondly dont even think of opting for iball PSU..they suck by real time
So being in India choice is left only to two giants..
Antec which is totally not affordable...and other is VIP
I myself use VIP P4 300 watt(rated) PSU...
well Even on this PSU, i connect X1900GT, HDD, LED lights, and DVD writter.
Dont be surprised by 300 watt mentioned...its actual power rating is somewhat 451 watt with 18amps on 12V...so no doubtly it supports a GPU which needs minimum of 400watt with 25 amps on 12 v.
you may confirm it from
here
At 1500 budget...trade in your present PSU for about 200 Rs so @ 1700 you culd get VIP 400Watt(rated) PSU which has the capacity to deliver 500Watt with 20amps on 12 V
