The problem is that the PSU is not standard ATX size, it's about half the size and I'm not sure what that standard is called.
So, you recommend a Pico PSU fed by a 12V linear regulated PSU? Would just any DIY version be fine or do you find large differences in regards to quality?
Any psu with the right specs for the PICO will be fine, however my friend upgraded from a standard power brick to the linear PSU mentioned above and was very happy with the change to the SQ of his rig. Please know his PC is solely setup for music playback and the rest of his chain is also at a high level. (Usually I want to rip the HD800's off my ears as I find the treble a bit too much - on his rig they sound pretty damn good!) The PSU he is using would be around $250 in parts (I'm guessing, a diy friend put it together for him, not a commercial product) but the builder has stressed that a cheaper linear psu, may not be worth it - apparently just because it's linear doesn't mean it's good, or will have the desired effect in a audio system.
I just thought I would mention this stuff as Greed was asking about the iUSB and getting the best out the 777. A few of my friends (IRL) have done similar build lately and all have been impressed with the outcome in their system. Also there is a fair bit of information on the JPlay forum in regard to Audio PC building + PSU's for PC's, if you are happy to do a bit of research.. There are also some "lab" style PSU's available from EBay which people on the JPlay forum say work pretty well.
