305 W PSU for legacy OptiPlex

This refurbished DELL HK595 power supply delivers 305 W for OptiPlex 330, 740, 745 and 755 desktops. It provides a single 24-pin main connector and one SATA power lead. The unit suits owners replacing a failed original supply in these specific models.

Steady 305 W output under load

The supply is rated to sustain its full 305 W continuously rather than only in short bursts. Voltage regulation remains within ATX limits during extended operation typical of office workloads. Thermal design matches the original chassis airflow path for reliable long-term service.

24-pin and SATA limits

The single 24-pin connector fits the proprietary motherboard header used by these OptiPlex systems. One SATA connector restricts the build to a single SATA drive or requires an adapter for additional devices. No PCIe or legacy Molex leads are present on this unit.

Perguntas sobre este artigo

How much heat and noise does the 305 W HK595 produce when running continuously in an OptiPlex 755?

The 305 W HK595 is rated for 305 W maximum output; actual heat and fan noise depend on the load drawn by the OptiPlex 755 components and the case airflow.

Which cables or adapters must I already have to connect the HK595 to a SATA drive and the motherboard?

The unit provides one 24-pin main connector and one SATA power connector; any additional SATA devices or peripheral power cables must be supplied separately.

Will the HK595 fit and power an older OptiPlex 330 without modification?

The HK595 is listed for the OptiPlex 330, 740 MLK, 740e, 745e and 755, so it matches the 330's 24-pin main and single SATA power requirements.
