while researching my possible PSU choices found this in the faq.
i plan to use gateway p3 system that i have sitting for some time. the specs on its factory PSU say
max output 110watt (thats funny , those online calculators suggesting i need 170 watt PSU to run this)
combined on 3.3 and 5 rail 80 watt max
12v - 2.5A
5VSB - 1.5A (standby i assume)
3.3v - 4A
so it looks like no PSU will give me 14A on 5V rail, but somthing tells me that it doesn't need that much. if it turns out a problem the point of load
3A regulator (CNX-P5V 15 Watt +5V Regulator) sold here could help. other then looks like pretty much any PSU will do. i heard a lot of complains about M2 units and so far without going to much into details looks like i better avoid those. i think i'll get by with OPUS 120 watt (~ half the price of 150). will 1 extra amper on 12v rail be enough to run Lilliput screen of it too?
i plan to run P3 1Ghz system with onboard
/NIC (might change to 667 celeron if absolutley needed), 2 sticks SDRAM 256 Mb, 3.5HDD ( would prefer 2 actually, to separate system and storage), CDROM (will disconnect after everything is built). planning to add GPS dongle, external slot loading DVD. IMO preformance would be adeqate for carputer purpose as it is running right now as media server for modded XBOX and torrent machine
and i find it quite usable.
given this info and data on current AC PSU which unit would you get for this setup? will i get by with OPUS120 (and som point of ue regulators if needed?)
