Ideas for lower power HTPC?
I have what I guess you'd call an HTPC setup by our front-room TV; it's on 24/7.
It's plugged into the TV (1366x768) via HDMI, and we use it to view Netflix on the TV or other movies thru the computer.
It also serves as a mini-server for the house, where everyone shares their music and photos.
OK, and it infrequently is tasked into light-gaming.
It's a C2D E5200 with a Radeon 5570 as GPU and a Samsung 1TB hdd.
It's housed in an old Antec tower, with a 300W Antec Basiq(?) P/S.
I got a Kill-a-Watt for Christmas, so I've been playing.
I was somewhat surprised that the E5200 described above idles at ~75w; that's 3-4w more idle power than my i2500k with Radeon 7950.
I have in the garage an Intel Atom D525 CPU/MB combo that I had used a year or so back, but it was god-awful slow.
My primary question is this:
Is there a ~ $100 CPU+Mobo(+integrated GPU to ~match the 5570) combo that would match the C2D E5200 in terms of speed, but significantly ( say, halve ) the power consumption?
My secondary question is how much is my "Basiq" 300W power supply contributing to the power suck? If I find a new efficient mobo+cpu, is the P/S going to negate some large portion of the power savings?
