I have built the following HTPC using the barebones of an old business workstation:
Core 2 Duo E6700
4GB DDR2 RAM
1x 7200 RPM SATA HDD
1x BluRay Combo
1x PCI-e TV Tuner
1x PCI Digital Sound Card
Currently just using a very old graphics card, and it needs to be upgraded to support BluRay playback - however, this is in a propriety (ie Dell) case, so the PSU is not upgradeable.
The PSU is 240W, rated @ 80%.
My current graphics choices are:
Using PSU calculators, I can see that the current setup, including the workstation gfx card, puts the machine at approx 237W, which I believe to be unrealistic, as the manufacturer would not supply a PSU that is only *just* covering the required Wattage.
The 6450 will put the recommended PSU size at 247W, and the 6570 a little bit above.
Please let me know if you think placing a 6670 in my currently described build would work with my current PSU.
