240W Dell MT Replacement PSU

This 240 watt power supply directly replaces Dell OEM units D240EM-00, HU240AS-00 and AC240NM-00. It fits Optiplex 3040, 3046, 3050, 5040, 7040 and 3250 mid-tower desktops plus Inspiron 3650, 3653, 3655, 3660 and 3668 models. The unit accepts universal 100 to 240 volt AC input for worldwide office use. It targets IT staff and owners repairing a failed original supply in these specific chassis.

Drop-in 8-pin and SATA harness

The adapter uses the original wiring layout with an exclusive 8-pin mainboard connector, a 4-pin CPU plug and multiple SATA drive ports. No extra cables, adapters or case modifications are required for installation. A thermostatic fan and industrial-grade capacitors keep noise low during continuous office operation. Builders needing non-standard connectors or higher wattage for discrete graphics cannot use this unit.

240W continuous with full protection

Rated at 240 watts continuous output, the supply delivers a stable +12 volt rail for daily desktop workloads. Built-in OVP, OCP, SCP and OTP circuits guard the motherboard and hard drives against surges, overloads and short circuits. It comfortably handles standard office configurations with integrated graphics and several SATA drives. Systems requiring more power for add-in cards or heavy multi-drive arrays exceed its capacity.

Questions about this item

How much continuous power can the 240W unit deliver before its protection circuits engage?

The supply is rated for a continuous 240W output on its +12V rail, with built-in OVP, OCP, SCP and OTP safeguards that activate if that limit is exceeded.

What noise and heat levels should I expect when the PSU runs all day in an office?

A temperature-controlled fan and industrial-grade capacitors keep the unit cool and quiet during long-hour continuous operation in a regular office environment.

Which Dell motherboard and drive connectors must my chassis already provide for this replacement to work?

Your system needs the proprietary 8-pin mainboard header, a 4-pin CPU power plug and standard SATA power ports for hard drives.
