SKU CH-Y148-SXE7E

300 W tower power supply with a 24-pin ATX connector, four straight SATA connectors and a 4-pin (2x2) connector for compatible Dell Vostro and Inspiron desktops

  • Delivers 300 W to power Vostro tower systems
  • Genuine OEM replacement matches original part numbers
  • Single 24-pin ATX connector fits motherboard directly
  • Four straight SATA connectors support multiple drives
  • 4-pin 2x2 CPU connector supplies processor power

Genuine OEM 300W PSU for Dell Vostro Towers

This genuine OEM replacement power supply unit delivers 300 watts of continuous power for Dell Vostro 200, 220, 230, 260, 270, 400, 410, 420 and 430 tower systems. It matches the original factory specifications and connector layout for a direct swap. Builders restoring or repairing these specific chassis will find the correct fit without adapter cables.

Steady 300-watt output under continuous load

The unit is rated for a maximum of 300 watts sustained delivery rather than a short peak figure. Its tower form factor and internal cooling are designed to maintain stable voltages across the 24-pin ATX, four SATA and single 4-pin (2x2) rails during extended operation. Systems running multiple drives or expansion cards stay within the rated envelope without voltage droop.

Direct-fit installation with keyed connectors

Installation follows the standard tower PSU mounting pattern using the existing case screws and the keyed 24-pin, SATA and 4-pin (2x2) plugs. The straight SATA connectors route cleanly along the drive cage. The most common issue is ordering this unit for a small-form-factor or proprietary Dell chassis where the tower form factor will not physically fit.

Questions about this item

How much heat does the 300W unit produce when running all day?

The 300W PSU is a tower-form-factor switching supply; typical efficiency means some waste heat, so keep the case vents clear and the intake fan unobstructed for continuous operation.

What existing connectors must my motherboard already have for this PSU to work?

Your board needs a 24-pin ATX socket and a 4-pin (2x2) CPU power header; the four straight SATA plugs serve drives you add.

Will this supply fit the older Vostro 200 chassis I still use?

Yes — the tower form factor and connector set match the Vostro 200, 201, 220, 230, 260 and 270 models listed in the compatibility data.
