Choose auld skool vs nu skool:
Silverstone ST400 400W ATX 12V 2.2
1 pcie 6pin, 2 x Dual SATA
Efficiency: >70% (Max 79.69%)
2 x 18a +12v rails:
+3.3V@28A,+5V@30A,+12V1@18A, +12V2@18A,-12V@0.5A,+5VSB@2.5A
vs
Corsair CMPSU-400CX 400W ATX12V V2.2 80 PLUS Cert, Core i7
Active PFC
1 pcie 6pin, SATA x6 (= 3 x dual sata?)
1 30a +12v rail:
+3.3V@20A,+5V@20A,+12V@30A,-12V@0.8A,+5VSB@2.5A
I know nothing about the other rails.
I'm leaning toward the Corsair because of 80+ and AFPC.
400w psu seems best to operate in efficient range.
Loads? for reference, this eventual config:
ECS A780GM-A ATX mobo (tho I'm looking at "oc for idiots" of intel Q66xx | Q82xx | Q94xx (?) Hmmm, but cpu power should remain <120W?)
2x16gb=32gb 1066 ddr2 (but possibly 4 smaller 800 ddr2)
Cpu max 95w TDP quad (95w is max of ECS mobo)
DVI gfx card, prefer passive/fanless (large hi res 3d renders, 0 or low fps)
IGP for secondary VGA display.
FDD, "some" HDD (RAID? "0/1/10")
2 opticals, but would burn on only one.
gigabit LAN
Externals.
The usual ps/2, etc. Printer.
External drive, probably self-powered. eSATA or usb2.0 [esata may be newegg error Ecsusa: no eSata]
Scanner.
Possibly a drawing tablet.
