ATX3.0, Short Body, Platinum Conversion Rate| Hydro PTM X PRO ATX3.0 PCIe5.0 1200W White Unboxing FSP

The Hydro PTM X PRO series has been released, offering both 1000W and 1200W models. However, only the 1200W model is available in a white version. This line supports ATX 3.0 and PCIe 5.0 and features a platinum conversion rate along with a 13cm short body design – a combination of features that is hard to find in the market.

The Hydro PTM X PRO ATX3.0 PCIe5.0 1200W White model comes with fully modular white flat cables, making it easy to create an all-white build. The power supply is cooled by a black 120mm FDB liquid-bearing fan, which automatically stops when the load falls below 30%, thanks to a low-temperature shut-off switch.

Equipped with 450V, 105°C Japanese large capacitors, and Japanese industrial-grade electrolytic capacitors, the Hydro PTM X PRO ATX3.0 PCIe5.0 1200W White model delivers a +12V single power output. With a conversion efficiency of 92%, it has earned 80PLUS Platinum certification and includes multiple protective mechanisms such as OCP, OVP, OPP, SCP, and OTP.

With dimensions of 130x150x86 mm, the Hydro PTM X PRO ATX3.0 PCIe5.0 1200W White is more compact than typical power supplies, which usually measure between 14 and 16 cm in length. The combination of its large wattage capacity, platinum rating, and shorter body design is quite uncommon.

Ensure that the power cord is fully inserted when connecting it, as improper insertion can lead to meltdowns. According to a survey by Nvidia, most meltdowns in 12VHPWR power supplies are due to this mistake. When using the power supply, make certain to check that the cables at both the graphics card end and the power end are correctly and securely plugged in.

The full-modular cable layout features white flat wires, with the 12V main wire conforming to 16AWG 300V specifications. This design includes 1 ATX/MB 20+4 Pin connector, 2 CPU 4+4 Pin connectors, 2 PCIe 6+2 Pin connectors with a one-to-two wire configuration, one 12VHPWR connector, 1 cable with 4 SATA connectors, 1 mixed cable with 2 SATA / 2 MOLEX (large 4Pin) connectors, and 1 mixed cable with 2 SATA / 1 MOLEX / 1 FLOPPY connector.

FSP Hydro PTM X PRO ATX3.0 PCIe5.0 1200W White Stress Test

For this evaluation, the OCCT power supply test was utilized to emulate a high-power consumption operational environment. The HWiNFO64 software, in conjunction with a power meter, was used to document both voltage and power consumption.

Test Platform:

  • Processor: Intel Core i9-12900K
  • Motherboard: ASRock B760M PG SONIC WIFI
  • Display Card: AMD Radeon RX6800 XT
  • Memory: KELVV DDR5-6200 16GBx2
  • Operating System: Windows 11 PRO 21H2
  • Radiator: Lianli GA II TRINITY 360 ARGB White
  • Power Supply: FSP Hydro PTM X PRO ATX3.0 PCIe5.0 1200W White

A 30-minute power supply stress test was conducted using OCCT, with the CPU drawing 235W and the GPU 255W, making a total of approximately 490W. The power meter recorded 572.5W, while the HWiNFO64 showed voltages of +12V at 12.000V, +5V at 4.992V, and +3.3V (3VCC) at 3.264V. The results indicated that the voltage was quite stable.

The FSP Hydro PTM X PRO ATX3.0 PCIe5.0 1200W White adheres to the platinum conversion rate and the ATX 3.0 standard. This model employs full-modular cables and includes native 12VHPWR cables. There’s also an ECO switch located at the back of the power supply, allowing users to choose whether or not to engage the fan stop function. With a compact 13cm length, it’s packed with excellent features.

Retailing at 8,590 yuan, the FSP Hydro PTM X PRO ATX3.0 PCIe5.0 1200W White is 100 yuan more expensive than its black counterpart. Given that the body shell and modular cables come in a white design, the additional 100 yuan is considered reasonable. However, FSP currently does not offer lower wattage or entry-level white power supplies. For those seeking to match white hosts, the choices are limited to this model and another SFX size. Hopefully, FSP will expand its range of white power supplies in the future!
