300w HTPC power supply w/AMD E-350 and HD 7750? will it work?

I got a little HTPC project on my hands. I ended up buying an MSI e350is-e45 AMD based apu=cpu/gpu a couple months ago on the egg for $49.99 after promo and rebates. This is the slightly smaller miniATX as apposed to microATX

Now im in the hunt for a case with power supply combo and i should be able to find one for <$50, micro or mini cuz mini's will fit in micro.

Im noticing most have a 250-300w power supply which seems to be way overkill for this apu which from what i can tell have a max tdp of 16w on the cpu and 18w on the gpu for a theoretical total of 32w, although reviews show the total cpu+gpu burn to be at about 23w. Severely efficient.

So if i buy a case with a 300w power supply, lets say 70% efficient so 210w max, it seems totally plausible and highly likely that i could run a single AMD HD 7750(55w tdp, powered thru pcie slot) in the pcie16x(4x effective) slot that the board has. Keep in mind i will need a bluray drive as well, im not sure of the power draw there but it should be low.

How does this sound? Anybody have any recommendations? Thanks Tom's!!!!

  1. PSU wise it would work. Physically getting the card in might be an issue + it will be bottlenecked by the X4 speed.
