Rectangular metal power supply unit with 24-pin connector and 4-pin CPU plug

Vszerda

Vszerda DPS-300KB B 300W power adapter

SKU CH-QEJ3-VV6M8

A 300 W desktop power supply with 24-pin and 4-pin CPU connectors, active PFC, 100-240 V input and 80 Plus certification

  • 300 W output supports desktop workloads
  • 251 W minimum rating ensures stable power delivery
  • Active PFC improves efficiency across 100-240 V input
  • 24-pin ATX and 4-pin CPU connectors fit standard boards
  • CE certified with 80 PLUS level for reliable operation

Replacement desktop power supply

The Vszerda DPS-300KB B is a 300W switching power adapter built to replace the Delta unit in compatible desktop systems. It delivers a rated output between 251W and 300W and carries CE certification for safety compliance.

Active PFC and 80 PLUS certification

Active power factor correction helps reduce harmonic distortion on the mains supply while the 80 PLUS certification indicates efficient energy conversion under typical desktop loads. The unit accepts a wide 100V-240V input range for global use.

Fixed 24-pin and 4-pin CPU connectors

A non-modular design means the 24-pin main connector and 4-pin CPU power lead are permanently attached, simplifying installation in space-constrained chassis. The included packaging protects the adapter during transit and storage.

Questions about this item

How do I install the Vszerda DPS-300KB B and connect the 24Pin and 4 pin CPU power connectors correctly?

Align the 24Pin main connector and the 4 pin CPU connector with the motherboard sockets, press firmly until the clips latch, then plug the IEC cable into the 100V-240V input. The step often missed is seating both clips fully before powering on.

What maintenance or replacement will the Vszerda DPS-300KB B need over time?

Clean dust from the intake and exhaust vents periodically to maintain airflow through the active PFC circuit. The internal fan is the only moving part; if it becomes noisy or stops spinning, the entire 300W unit must be replaced.

What limit appears first when the Vszerda DPS-300KB B runs at sustained load near 300W?

The 300W maximum output rating is the first limit; exceeding it triggers over-current protection. Continuous operation at the upper end of the 251W-300W range also raises internal temperatures, which the active PFC and fan must manage.
