Replacement for Dell Studio XPS 8000/8100

This 350W power supply replaces the Delta DPS-350VB C ATX0350P5W unit found in Dell Studio XPS 8000 and 8100 desktops. It fits a wide range of other brands and models that use the same form factor. The reduced depth improves chassis compatibility. It restores reliable power to systems with a failed or ageing original unit.

Single-rail output with 12V at 16A

The unit uses a single +12V rail rated at 16A alongside 3.3V and 5V rails at 13A each. Minor rails provide -12V at 0.8A, -5V at 0.5A and +5VSB at 2.5A. Input voltage covers 115V and 230V at 50Hz or 60Hz. Hold-up time is 17ms minimum and rise time is under 70ms at nominal input. MTBF exceeds 100,000 hours.

20+4-pin motherboard connector for 20-pin

The 20+4-pin main connector works with both 20-pin and 24-pin motherboard sockets. This covers older ATX boards and newer 24-pin designs without adapters. The upgrade is worth it when the original Delta unit fails, runs hot or causes instability. It is not for builders who need higher wattage or modular cabling for modern high-power components.

Questions about this item

How do I fit the 20+4 pin motherboard connector onto a 24-pin socket?

Press the combined 20+4 block straight into the 24-pin socket until the latch clicks; do not force the 4-pin section separately or pins can bend.

Which rail should I watch for degradation after several years of 24/7 operation?

The single +12 V rail rated at 16 A carries the CPU and GPU load; its capacitors age first under sustained heat.

What thermal limit appears first when the unit runs continuously at full 350 W load?

Hold-up time drops below the 17 ms minimum once internal temperatures exceed design limits, causing unexpected shutdowns.
