A week ago, I've acquired Asus E45M1-I Deluxe motherboard. It has an AMD E-450 APU onboard, passively cooled heatsink, onboard WiFi with bundled antennas... really nice board. I'm planning to use it as HTPC/media server (CM Elite 120 is what I will house it in). Now, it also has a PCI-e x16 slot which gave me an idea...
... what if I throw my GTX 560 Ti in there? I realize the setup would be severely bottlenecked by the CPU, but still... any gaming possible?
1) If yes, will Corsair CX430 V2 be sufficient to power the setup, since the board/CPU combo should only take about 18W or so? If that's not sufficient but gaming IS possible, what PSU should I look at?
2) If no gaming is possible, please suggest a PSU for this setup. In that case I'd like to stay as low as I can, but for some reason I can't find any reliable low-wattage PSUs nowadays... seriously, an average office system doesn't take over 250-300W nowadays, why is the lowest I find 400W?
