ATX supply with dual rails

This ATX power supply delivers +12 V at 4.5 A and -53 V at 3.7 A for a combined 250 W output. It suits builds or test benches that require both a positive and a negative rail from a single unit. The unit is new and has been tested working by the supplier. It fits standard ATX mounting points in compatible chassis.

Limited by fixed rail currents

The +12 V rail tops out at 4.5 A and the -53 V rail at 3.7 A, so total power cannot exceed 250 W across both outputs. Systems drawing more current on either rail will need a higher-rated supply. The fixed voltages also mean this unit cannot serve builds that require adjustable or additional output levels.

Questions about this item

Should I pick the +12V 4.5A rail or the -53V 3.7A rail for my build?

The supply delivers both rails simultaneously; the +12V line provides up to 4.5A and the -53V line up to 3.7A, so choose based on which voltages your components require.

What does the 250W rating mean once the unit is installed in a real machine?

It indicates the combined continuous output the supply can sustain across the +12V and -53V rails without exceeding its thermal limits.
