power supply 100-240v/12V-34A(2x17) 85% randament has arrived

silverston SS430GB pc power supply
it can handle
input 110v-240v range (144v is in range) 7A top
this pc power supply is rated 82+ at 110V

from my test i have 85% conversion at 144V
for 100W drain i get 85W output

features output dual 12v 17A rails from independent outputs
17A for elecronics
17A for lights
i think that is enough for all i have

maximum power on 12v is 360W
power supply is protected to overcurrent shortcut and has thermal shutdown

for dc imput i need ti remove first AC-DC block and the converteri s ready

i need to make new sealed case 150x100x100mm from aluminium blocks wich is enough to remove the fan and cool the power supply

mods
i have removed all useless dc lines 3.3V, -12V and 5V
i have added an swich to power the supply (soft start)

pictures of modded power supply are atached
last picture is an closeup for the ac-dc block
you need to remove it and plug the battery in place of his marked "+"."-" terminals
