The FSP Hydro PTM X Pro 1000W ATX 3.0 PSU Review: Premium Platinum Power

Power Supply Quality

As part of our testing, we also check output parameters are within specifications, as well as voltage ripple and line noise.

The electrical performance of the FSP Hydro PTM X Pro 1000W PSU is excellent, even for a top-tier product. It displayed outstanding filtering, with a maximum ripple of 30 mV on the 12 V line and 16/14 mV on the 3.3V/5V lines respectively. Regulation is great as well, with the unit maintaining the regulation below 0.9% on all three of its primary power outputs.  

As part of our standard testing, we test the primary protections of all PSUs we review (Over Current, Over Voltage, Over Power, and Short Circuit). The FSP Hydro PTM X Pro 1000W ATX 3.0 unit successfully passed all of the tests, generally reacting timely when needed and shutting down to protect itself and the components it is powering. The OCP and OPP protections are set a bit high, with the unit almost immediately reacting to 135% current and 128% load respectively. These protections generally tend to be slack on ATX 3.0 units due to the power excursion requirements.

Conclusion

In conclusion, the FSP Hydro PTM X Pro 1000W ATX 3.0 PSU is a unit that features a design combining reliable topologies with great quality components. The company’s engineers are using top-line active components that were essentially required to achieve its very high-efficiency ratings, as well as only Japanese capacitors from Nippon Chemi-Con that are known for their durability, ensuring that the unit can withstand heavy use and deliver consistent power.

Perhaps the most prominent feature of the Hydro PTM X Pro is its excellent electrical performance. The unit delivered outstanding energy conversion efficiency, even for an 80Plus Platinum certified unit, and can reach the certification's requirements regardless of the input voltage. Additionally, the voltage filtering and regulation are exceptional, ensuring stable power delivery to the system.

The thermal performance of the Hydro PTM X Pro is also noteworthy. The design favors reliability and low temperatures over acoustics, resulting in minimal-to-zero thermal stress. The unit’s components operate at very low temperatures, which is great for its longevity. However, the noise output of the Hydro PTM X Pro is mediocre, it's quiet at lower loads and tolerable at higher loads at room temperature, but with high noise output if both the load and the ambient temperature are high.

The Hydro PTM X Pro comes with a high MSRP price of $279, which may deter some buyers. However, we expect that the market price will decrease over time, making it a more competitive option for advanced gamers and enthusiasts. Overall, the Hydro PTM X Pro offers great performance and reliability. Despite the lack of groundbreaking features or figures, it is a solid choice for users looking for a dependable ATX 3.0 power supply unit with good all-around performance.
