The new generation of RTX 40 graphics card fully adopts the new power supply interface of 12VHPWR, and after Intel released the power supply design specification of ATX Version 3.0, we finally saw the power supply manufacturer FSP FSP launched a new generation of new power supply products that meet the ATX12 V3.0 specification. The “Hydro PTM PRO ATX3.0 PCIe5.0 1200W” power supply with the king’s layout LLC full-bridge resonant architecture and DC-DC synchronous rectification design will be paired with NVIDIA RTX 4090 to measure the power supply performance.

FSP Hydro PTM PRO ATX3.0 PCIe5.0 1200W power supply out of the box / Platinum Japanese 200 % Instantaneous overload is also possible
FSP’s high-end power supply Hydro PTM PRO 1200W not only has 80 PLUS Platinum certification but also has a conversion efficiency of up to 92%. The 12V available power is maximized, and it is equipped with an all-Japanese 105°C electrolytic capacitor and a 120mm FDB liquid-bearing fan.
This revision is in line with the ATX12 V3.0 and EPS12V V2.92 specifications, and adds 12VHPWR power supply connectors and wires, allowing players to supply the RTX 4090 with one line of power. Of course, the power supply has a new 12VHPWR power supply connector, which does not mean that it has been designed in accordance with the ATX12 V3.0 specification, which is what players need to pay attention to.
In the ATX12 V3.0 specification, the peak current of the CPU is first increased. For example, a 165W TDP CPU should be able to give a maximum current of 40A, while 125W TDP is 39A, 65W TDP 34A, and other peak current requirements. And relax the +12V voltage regulation rate to +5%~-7%, that is, the dynamic change between the highest +12.6V~+11.20V.
More importantly, the dynamic current output of +12V3/4 for the PCIe graphics card power supply should be able to achieve a 300% instantaneous change. At the same time, when a power supply of more than 450W is used with a 12VHPWR connector, it should be able to withstand a power overload of 200% for an instant 100µs under 10% load.
At the same time, it meets the above ATX12 V3.0 specification and increases the power supply of the 12VHPWR power supply connector to meet the new specification. The 12VHPWR uses a 12+4 pin connector and uses a 12AWG wire to supply a maximum power consumption of 600W, while the current RTX 4090 The founding version has an average power consumption value of about 450W.
The appearance of the new Hydro PTM PRO ATX3.0 PCIe5.0 1200W power supply has not changed. It is still painted with high-quality matte black paint and matched with a large 135mm FDB bearing fan. And provide side label stickers in the accessories to allow players to change the color by themselves.
The top of the power supply uses a large 135mm FDB bearing fan for active cooling and has a test and a warranty sticker from Broadcom. On the AC input side, there are AC input sockets, the main power switch, and the ECO mode switch. When the power load is lower than 30% when ECO is On, the fan will automatically stop to achieve a better mute effect.
The modular output connector is grouped by white lines and indicates the function of the connector. The upper right corner is the PCIe 5.0 Ready 12VHPWR connector (PCIe 12+4 Pin), and the left-hand side has 4 PCIe power outputs, as well as 2 CPU power supplies, 5 A peripheral power supply, and modular connectors such as ATX 24 pin power supply.
Hydro PTM PRO ATX3.0 PCIe5.0 1200W power supply standard, +12V can carry up to 100A, 1200W specifications.
Simply look at the internal design of the Hydro PTM PRO ATX3.0 PCIe5.0 1200W power supply, which mainly adopts a single-channel +12V, LLC full-bridge resonant architecture to ensure the stability of the output voltage of the power supply from low load to high load, and DC-DC synchronous rectification design. And its main capacitor adopts Japanese 450V, 105°C electrolytic capacitors to ensure reliability under extremely high current output.
And the circuit board adopts an industrial-grade unique moisture-proof coating, emphasizing the protection of moisture-proof, dust-proof, and rust-proof, and can work normally even in a high-humidity environment. The power supply has an additional heat sink for the 12V switching circuit, which makes the components work more stable.
The fully modular design uses black flat wire, which makes it more convenient for players to install the machine and the whole line, while the 12VHPWR cable is covered with a woven mesh. As for the power supply of the motherboard, ATX 20+4 pins are provided.
The power supply provides 3 cables with a total of 6 PCIe 6+2 Pins. It is recommended that a separate cable be connected to only one connector; if the new card has been connected with 12VHPWR, these 3 PCIe module cables can be installed without Power being on.
The power supply provides 2 3 CPU/EPS 4+4 Pin cables, that is to say, one of them provides 1 CPU/EPS 4+4 Pin, and the other provides 2 CPU/EPS 4+4 Pin; the current CPU power supply At most 2 CPU/EPS 4+4 Pins are used, so it is recommended that the power supply be connected to the motherboard with a separate cable.
For the peripheral power supply, there are 2 8 SATA cables, 2 4 SATA / 4 large 4-pin cables, and 1 2 SATA / 1 large 4-pin / 1 4-Pin floppy cable.
Hydro PTM PRO ATX3.0 PCIe5.0 1200W and RTX 4090 stress test
To use OCCT stress test software to perform dual load test of CPU and GPU, and check the +12V, +5V, and +3.3V voltages reported by the motherboard through the software conditions, as well as GPU power consumption and current changes when using the NVIDIA PACT tool to test the game; the hardware used is an Intel Core i9-12900K processor and an RTX 4090 Founders Edition graphics card.
Processor: Intel Core i9-12900K
Motherboard: ASRock Z690 PG Velocita
Memory: CORSAIR DOMINATOR PLATINUM RGB DDR5 32GBx2 5200MHz
Graphics Card: NVIDIA GeForce RTX 4090
System Disk: Solidigm P41 Plus 1TB PCIe 4.0 SSD
Heat Sink: 280mm AIO Water Cooling
Power Supply: Hydro PTM PRO ATX3.0 PCIe5.0 1200W
Operating System: Windows 11 Pro 21H2
Stress test on CPU and GPU through OCCT, the total wattage of the computer during the test is about 847W, and the motherboard voltage information monitored by OCCT can be seen It is stable between 12.096-12.192V up to +12V, and the same is true for +5V and +3.3V, which meets the stable and high wattage required by high-end CPUs and GPUs.
Then use the NVIDIA PACT tool to maintain the 3 groups of 12V 8Pin at 12.192V and 12.184V during standby. Then, under the performance settings of 4K, crazy light chasing, and DLSS 3, the average power consumption of the GPU came to about 343W, and the instantaneous maximum was 382W.
The 3 groups of 12V 8Pin consume the current and power consumption of 12.528A / 150.937W, 2.736A / 33.226W, 11.480A / 137.852W respectively.
Finally, using the Furmark Xtreme burn-in test, the GPU reached an average power consumption of 458.2W and an instant 482.4W. The three groups of 12V 8Pin consume the current and power consumption of 13.240A / 159.092W, 5.152A / 62.401W, and 19.040A / 227.414W respectively.
Hydro PTM PRO ATX3.0 PCIe5.0 1200W power supply can provide stable +12V voltage and output under the test of OCCT dual burn or Furmark Xtreme burn-in, 4K crazy light chase in “Electric Rebel 2077” Wattage to meet the power requirements of modern high-end CPUs and GPUs.
In addition, both the RTX 40 series graphics cards and the RTX 30 Founding Edition use PCIe 12+4 Pin (12VHPWR) connectors. If the power supply is supported, only one cable can be used to power the GPU, and the original 12VHPWR can be converted to 4 Put away the PCIe 6+2 Pin adapter cables, otherwise, the original domineering new graphics card will have an extra shot.
As for the use of PCIe 12+4 Pin (12VHPWR) connectors, remember that the power supply end and the graphics card end must fully insert the connectors of the cables to be connected to the sockets. Only when the connectors are fully contacted can they be used safely. The original wire connectors will be designed It is a little tight, so the installer must check whether each connector is inserted all the way when installing the power module cable.
The Hydro PTM PRO ATX3.0 PCIe5.0 1200W new power supply is priced at NT$ 7,990 in Taiwan, which is only $500 more than the previous generation of the same model power supply. In comparison, you must bring a new graphics card. The latest power supply that complies with the ATX12 V3.0 specification can have a stable power supply and one-line supply to meet the power supply requirements of the RTX 4090.
