I would like to know if amperage matters when buying a new power supply. My current power supply has these specs.
+12v @ 19a, -12v @ 0.8a, +5v@25a, +5vsb@2a, +3.3v@18a
i know that 12v rail is what i want and should i buy a power supply with higher 12v amperage? or same? or lower?
yes it matter but it also depends on what your using it for...it will tell you the wattage of each Voltage plain so you know if said plane can handle the components you wish to use. also get a quality supply like seasonic, xfx, PC power and cooling, corsair...cheap psu's kill more PC's
what is your usage model...what parts you have for your pc? can help more if i know.
