Description
Computer power supply from Seasonic. It is certified with 80 Plus Platinum, which relates to its performance in relation to its nominal power in Watts.
This specific certification applies to power supplies for high-performance computers with high consumption or companies with multiple computers where the benefit works cumulatively. It is full modular, meaning it has fully detachable cables, allowing you to use only what you need, offering a more organized composition with better aesthetic results and airflow. It provides protection against short circuit, protection of connected devices from excessive current intensity, protection of connected devices from excessive voltage, protection of connected devices from low voltage, protection to prevent exceeding the nominal power, protection against excessive temperature. Compatible with ATX computer case.
80 Plus Platinum Certification
Premium Hybrid Fan Control
The vast experience of Seasonic in designing the quietest and most efficient power supplies in the market has been translated into the development of Hybrid Mode, an advanced fan control that allows users to maintain the overall fan noise at the lowest possible level.
Fluid dynamic bearing fan
Your PC will have great durability over time thanks to the high-performance fluid dynamic bearing fan, which manages to keep noise and heat levels low compared to ball bearing fans. Lubricating the surface of the spheres reduces friction and vibration, thus reducing overall energy consumption. Thanks to the smooth and silent rotations of the fan and its sturdy construction, the fan's lifespan is quite long, reaching up to 50,000 hours at 40°C.
Cable-Free Arrangement
The engineers at Seasonic have implemented a new design feature, where instead of cables, the back panel and PCB (Printed Circuit Board) are connected with a copper plate. This innovative solution not only reduces the chances of production errors during manual placement, but also improves the quality of the power output.
Connections
- 1x ATX 20 + 4-pin motherboard power connector.
- 2x EPS/ATX12V 8 Pin (4+4) Cable CPU power connectors.
- 4x PCIe 6+2 graphics card power connectors, to take advantage of modern GPUs in combination with your PC's capabilities.
- 10x SATA power connectors for SSD or HDD hard drives.
- 3x Molex 4-pin connectors for additional peripherals.

Reviews
The evaluation concerns the Seasonic Prime PX 750W Full Modular 80 Plus Platinum.
I replaced a "CoolerMaster MWE 650 Bronze V2 650W" (which will be used in another system) because I needed a slightly higher wattage margin and a somewhat higher quality and flexible power supply based on my requirements and future upgrades. I chose this specific model because of the good price at which I found it (128€) compared to its good rating in the reliable Cybenetics database.
The power supply comes with good labeling for "what connects where".
The cables are flat (except for the 24-pin) and the number of cables is satisfactory. Although the cables are not sleeved, the average beginner user will not be particularly bothered.
It also comes with a good number of cable ties and adhesive tapes. Personally, in my case (CoolerMaster NR600), I easily organized the cables without using cable ties.
The packaging also includes a typical 24-pin connector (tester) for a quick and standard test of the PSU before connecting it to the system.
Like most PSUs on the market at the moment, it does not have 12VHPWR connectors and requires the purchase of an additional adapter, either through Seasonic (after consultation) or through specialized stores.In a typical test I performed before connecting it to the PC, in fan mode, the fan motor made a typical noise of a medium-quality fan motor, but relatively low in dB (in no way is it at the level of Noctua or other companies that produce their own high-quality fans). However, when placed in a silent system, it was "masked" and the bad profile of this low noise motor was somewhat covered. In hybrid mode, it was silent even outside the computer case.
After 2-3 weeks of use, the first differences I noticed in my system (always compared to the previous PSU I was using) are as follows:
+ All subsystems have a lower temperature by 1-2°C.
+ The temperature fluctuations of the processor that are recorded are significantly smaller.
+ The processor synchronizes at slightly higher frequencies.
+ The system restarts faster by 4-5 seconds.Translated from Greek ·- Cable management

Did you find this review helpful?- This review is about the power: 650 W
The first experience with this specific power supply is that it has a very high-quality construction with detachable cables. Now it has not been tested under full load. Waiting for the new graphics card and an update of the evaluation will follow.
