Will the Low Profile Radeon HD 5570 run on my Dell Optiplex 780 SFF with a235w PSU

[spot_me01]

Hi i am new to the Forums, i have been doing research and need to find out if the Low Profile Radeon HD 5570 will run on my:

Dell Optiplex 780 Small Form Factor (sff), which has a 235w PSU, 2GB 1066MHz DDR3 SDRAM (also getting another 2GB DDR3 which is in the mail). with a Intel Core 2 Duo E7500 2.93ghz, and a 1.5TB HDD.

Some people online are saying that the Low Profile Radeon HD 5570 will work with my PSU and some are saying that it needs a minimum of 400w PSU to run, but anandtech test show its TDP is 42.7w.

Do you think my computer will run this Card?

Your help will be much appreciated.

You should be alright. The maximum the card will draw is 42W. But realistically it'll probably be closer to 30-35W when gaming.

Even with the HD5570 the system won't even come close to needing 225W. I would estimate your system would use at the very most 135W under a gaming scenario.
