I have an HP dc7700p machine I use as an HTPC. It has 2GB RAM and plays 720p video just fine. I want to buy a dedicated video card for it so that I can have an HDMI port to hook it up to my new projector AND play Blu Ray movies.
Can someone recommend a video card that can do all this, is low profile and will work with the 240 watt power supply?
EDIT: Huh, actually you may have a problem with the card I linked to (that Asus 4350). It apparently comes with a 2-slot low-profile bracket, but your dc7700 looks like it only have 1 slot on the back. Unless you want to cut the bracket apart (with a hacksaw or dremel), it might not work.
The HIS card you linked appears to have two separate brackets, so you can just leave-off the one with the old D-SUB port, but I worry that the 5450 draws too much power for your 250W PSU.
Absolutely no gaming will be done on this HTPC, its purely for MKV files,DVDs and Blu Ray. I'm still not sure about the dc7700p having enough power for the 5450 although a couple of people have said it will be fine? I used a power calculator online and it said with this 5450 video card it would need 200 watt PSU. The dc7700p comes with a 240 watt PSU so in theory it should be fine? Thoughts?
On the power requirements, all I can tell you with any certainty is that AMD recommends a 300W PSU for the 4350 (without specifying how much power it draws) while they recommend a 400W PSU for the 5450 (but it only uses 19W).
I would say that with only a 19W power draw, the 5450 should be fine. It's newer technology than the 4350 and is possibly more energy efficient (and at 19W, I can't imagine its any worse).
