SPARKLE SPI460PFB2-MC2 460W is what I have, wondering if its good enough for a gtx 750ti.

Alright, so my current PSU is running at 12v1@16A + 12v2@ 16A and 460 watts

I am aware that for the gtx 750ti, you are requiered a minimum of 12v@20a and 400 watts.

I am also awared that my current PSU is decent but apperently not decent enough for the video card that I have in mind on buying.

The real question is, can both 12v RR be connected to the graphic cards to reach the minimum of 20As? If that is not possible, would anyone recommend for a decent single RR that has enough watts and enoigh AMPs to run the graphic card.

Thanks :)

  1. Look i gtx 750 ti will be fine as long as you have processor that consumes less wattage or amperes. I need your total system specifications. Most of the time in dual rail power supplies the rail with the high ampere is for processor and graphic card and sometimes motherboard only while the other rail is for other system components like HDD, rams and dvd roms and mostly motherboards. So please provide definite specifications so that i can answer you.
  2. AMD FX-4100 CPU, 8GB DDR3, NVIDIA GT610, 1TB HDD, 24X DVD+-RW & Win 8 64-Bit

    The PSU I'm running
    +3.3V@22A, +5V@20A, +12V1@16A, +12V2@16A, -12V@0.5A, +5VSB@2.5A

    Yes you should be fine, the 750ti uses around 5-6 amps on 12v.
