Replacement Power Supply for Dell Precision

This ATX power supply replaces the original unit in Dell Precision 380, 390 and T3400 workstations. It delivers +5V, -5V, +12V1, +12V2, +3.3V, -12V and +5V-SB rails through a 24-pin ATX connector, a 4-pin P4-12V connector, three SATA connectors, three LP4 connectors and one floppy connector. The reduced-depth form factor improves chassis compatibility.

ATX Interface Limits

The supply accepts 110 V or 220 V AC input at 47 to 63 Hz and is hi-pot tested for low ripple and noise. Rise time is less than 70 ms and hold-up time is at least 17 ms at nominal load. A single fan provides cooling within the standard ATX footprint.

350 W Capacity Decides Fit

The 350 W rating determines whether this unit can support your installed components. Buyers who need more power for additional drives or upgraded graphics should verify their total system draw before purchasing.
