PCI Express x16 Card with HDMI output that works with 250 watt PSU?

My parents have a cheap Compaq desktop PC -- the functionality it offers generally exceeds their needs. However, I would like to connect this PC to their television so they can watch streaming videos more easily. Unfortunately, the integrated video card that came with the PC only supports VGA output. I would like to add a new video card that supports HDMI output. The system board has an open PCI Express x16 slot which supports video -- but as I look on NewEgg, I notice many of the cards have minimum power supply requirements exceeding 250 watts. Surely there are some out there that work with 250 watts (or less)? Any model/brand recommendations?



Thanks,

Josh|||Vomit is correct, the Radeon HD 5450 and 6450 both run fine on 250 watt power supplies- the 5450 doesn't even draw 15 watts under full load. I recommend the 6450 because it can handle full HD Blu-Ray playback flawlessly.

ATI/AMD's published psu requirements on their sub-$100 card models are inflated way above what those cards actually use. For example, the much stronger Radeon HD 5670 and 6670 also have an "official" psu requirement of 400 watts, but even those cards don't have an external power connector and draw less than 60 watts under full load.... so those work fine on most 300W psus. For most computers with a 6450 or 5450 installed, total system power consumption is below 180 watts.
