The FSP Hydro Ti Pro 1000W PSU Review: Titanium Shines for FSP's Flagship Power Supply

Cold Test Results (~25°C Ambient Temperature)

For the testing of PSUs, we are using high precision electronic loads with a maximum power draw of 2700 Watts, a Rigol DS5042M 40 MHz oscilloscope, an Extech 380803 power analyzer, two high precision UNI-T UT-325 digital thermometers, an Extech HD600 SPL meter, a self-designed hotbox and various other bits and parts. For a thorough explanation of our testing methodology and more details on our equipment, please refer to our How We Test PSUs - 2014 Pipeline post.

The FSP Hydro Ti Pro power supply unit stands as a paragon of efficiency in its class, as evidenced by its stellar performance during room temperature testing, a testament to its 80Plus Titanium certification. This unit excels remarkably in its energy conversion efficiency, particularly at low to medium loads. The Hydro Ti Pro distinguishes itself from its counterparts with its unwavering efficiency across the full spectrum of load conditions, defying the common trend of efficiency decline at elevated loads. When subjected to an input voltage of 230 VAC, the Hydro Ti Pro boasts an average nominal load efficiency of a remarkable 95%, a figure that stands significantly above many of its peers in the power supply landscape. This exceptional efficiency recedes to 92.9% under a reduced input voltage of 115 VAC. Nonetheless, this dip may be significant but does little to overshadow the unit's overall performance, as it remains comparatively very high.

By design, the FSP Hydro Ti Pro features a sophisticated eco-mode for its cooling system, indicating that the fan's operation is dependent on the cooling requirements. However, the cooling strategy employed by this unit is notably efficient, with the fan commencing operation only when the load exceeds 500 Watts. This is a testament to the exceptional efficiency of the Hydro Ti Pro. Despite its substantial power output, the internal temperatures of the unit remain impressively low, a remarkable achievement considering its standard dimensions and high performance.

The cooling profile of the FSP Hydro Ti Pro is meticulously calibrated for minimal noise generation, particularly effective across the lower half of its load capacity. The fan does not even spin with loads up to 500 Watts, maintaining a quiet operation. Beyond this threshold, the fan's speed incrementally increases, but this escalation in speed is gradual and controlled, keeping acoustic levels in check. The fan never reaches a speed close to its maximum under these operating conditions, while temperatures remain very low.
