my xp idel 80-120mb
as far as power supplys go iv used 2 for ages now simply for more power
the only things on my 850wat is video an mobo/cpu so thers lots of clean power[barly ever see volt drops]
an the 500 wat does 4hd.s 2x ssd.s 1dvd rom an like 6 fans + an any lights or extras i may have [only 1 fans is hooked to the mobo ports for cpu reading disable thing dosent work]
its alot for 1 850wat to handel so you spread the load [so dirty lol]
Games coded and running in DX10 and DX11 use less RAM due to not having to clone GPU data, so you saving the 400 of RAM space is pointless cause you going to give it up to the game anyway. Also RAM for modern systems is piss cheap and getting 8 GB of DDR3 is only $50 to $120 depending on speed, timing, and brand.
Win7 also scales based on your RAM to ensure smooth performance, the less RAM you have, the lower RAM it uses. It will not be as responsive though so you should give it the 4 or 8 GB it wants anyway.
As for the PSU.... the stuff you got on the 500W is only like 70 or 80 watts of power total. Which means that PSU is well below 70% efficiency. You are literally burning more power from that wall than you need for no benefit what so ever. An extra 150 watts load on your 850 Watt PSU would make no difference in voltage drops, efficiency, or anything since at full load you are barely breaking 400 Watts, if that.
You should sell the 500 Watt and use the money toward a new GPU, second set of RAM, or BD when it comes out.
