Is gts450 better than 5770hd and gts250?.Can it run in my zebronics 400watt smps?

can it run in msi boston 1.0 motherboard and intel core 2 duo e7200 and windows 7 ultimate and with a 17 inches lcd monitor.Is it necessary to change any other settings of my pc?.|||Zebronics 400W is a cheap generic power supply rated for 17A on a single +12V rail. Don't use it. It's not adequate for any of the video cards you mention.



(In reality, a Zebronics 400W is more like a mediocre 300 watt power supply from 7 or 8 years ago.)



The recommended power supply for a GeForce GTS 450 is 400 watts or larger with at least 22A combined available on the +12V rails.



(The 500W version Zebronics power supply is rated for 22A on the +12V, so that would technically meet the requirement for a GeForce GTS 450, but I still wouldnt use it because the brand is generic crap.)|||A Corsair CMPSU-450VX (33A +12V) is a nice power supply. Antec NEO ECO 400C and Earthwatts EA430 are both similar to the Corsair 450VX (Seasonic designs, with 30A +12V). Seasonic S12II-430 Bronze (30A +12V) is very similar to the Antec NEO ECO 400C. Those would all easily handle a GeForce GTS 450.
