The Seasonic G-450 is still more power than Josh's latest build requires but is perfect for powering a SFF system as the unit is a mere 6.25" in length.  With a pair of 6+2 PCIe power connectors and 37A on the 12V rail you will be somewhat limited in your choice of discrete GPU, reasonable consider it is a 450W PSU.  [H]ard|OCP found the quality on this unit to be good overall and excellent compared to other lower powered PSUs but found the pricing somewhat confusing as the G-550 is a mere $10 more.

"Seasonic is continually short on marketing but long on performance, and we are good with that. Today's 450 watt G Series computer power supply makes more sense in this new world of lower power desktop CPUs and GPUs. Does the G-450 give its users solid power in this lower end of the spectrum range at the right cost?"

I don't think that the pricing on this is so surprising. At this low end of the spectrum, the PSU will be spec'd exactly to how much a user will need. If a builder thinks they might need the 550 watt PSU, they will get it, otherwise saving $10 on a build that might only be $400. One might also get better efficiency on the lower unit, by sticking closer to the %50 usage mark.
