+12V Rail: 12.096V

+5V Rail: 5.000V

+3.3V Rail (3VCC): 3.328V

Efficiency: The power supply’s efficiency appears to be very high, given the total system power draw versus the reading from the power meter.

These results indicate that the COUGAR POLAR X2 1050W PSU is performing well within its expected parameters. The +12V, +5V, and +3.3V rail voltages are stable and within standard ATX specification tolerances, which is crucial for system stability and component longevity. The high power draw from the CPU and GPU, which are among the most power-hungry components in modern systems, demonstrates the PSU’s capability to handle high loads without significant voltage drop, which is indicative of quality components and design. The overall system’s power efficiency also reflects well on the 80 PLUS Platinum rating of the PSU.

Maintaining such efficiency and stability under load is a good sign that the PSU can reliably support the system even during prolonged use in demanding conditions. It’s also worth noting that the actual power draw from the wall is higher than the combined reported power usage of the CPU and GPU due to the power requirements of other system components and the conversion efficiency of the PSU.

The screenshot shows the OCCT (OverClock Checking Tool) interface during a power supply and system stability test. The test has been running for approximately 29 minutes and 27 seconds. Here’s a summary of the readings displayed:

Processor (CPU): Intel Core i9-14900K operating at 99.0°C, which is at the upper limit of what is generally considered a safe operating temperature. It’s drawing 374W of power and running at a clock speed of 5355 MHz.

Memory: Utilization is at 13.7%, with a speed of 6723 MT/s, indicating the system’s RAM is not being heavily used during this test.

+5V: Stable at 5.000V.

+12V: Also stable at 12.096V.

CPU Package Power: Reporting as 374.15W.


The AIO (All-In-One cooler) pump is running at 2280 RPM.

The AIO pump shows a speed of 2461 RPM, suggesting a high-performance liquid cooling system.


P-Core 0 Clock: Running at 5400.00 MHz, indicating the CPU is likely overclocked or boosted.


Physical Memory Load: At 13.7%.

Total CPU Usage: At 100%, indicating that the CPU is fully utilized during the test.

No errors are detected, which is a good sign. However, the high CPU temperature could be a concern if it remains consistently at or near 99°C, as prolonged operation at such temperatures may affect the longevity of the CPU. It’s important to ensure that the cooling solution is adequate for such a powerful CPU, especially if it’s overclocked or under sustained load. The GPU temperature and power draw seem normal and within expected ranges.

The power readings indicate that the PSU is handling the load well, and the voltages are stable, which is crucial for system stability and hardware health. The conversion efficiency appears to be high, as the system is drawing around 617W but the PSU is outputting approximately 749.2W, which would include efficiency losses and power to other components not accounted for in the CPU and GPU power readings.

This image shows a power meter displaying the energy consumption of an electronic device, presumably the PC that is being tested with the OCCT power supply test mentioned earlier. The power meter reads:

Energy: 749.2W, which is the current power consumption being measured.

Cost: $0.38, which is the calculated cost of the power consumed during the running time, based on a specific electricity rate programmed into the power meter.

Time: 35:54, which may indicate either the time of day or the duration for which the power consumption has been monitored.

The reading of 749.2W aligns with the previously mentioned power consumption, confirming that the PC setup with the COUGAR POLAR X2 1050W PSU is drawing this amount of power from the wall during the test. This figure likely includes the total system power draw plus any additional losses due to the PSU’s efficiency, and possibly other peripheral devices that may also be drawing power. Given the power supply’s 80 PLUS Platinum rating, this reading suggests that the power supply is performing within its expected efficiency range.

The thermal image provided displays a heat signature of the COUGAR POLAR X2 1050W power supply unit after approximately 30 minutes of a stress test. The temperature readings from the thermal imaging camera are as follows:

The hottest area, likely near the exhaust where hot air is expelled, is at 38.5°C.

There are other regions with temperatures ranging from 28.7°C to 31°C, which are relatively cool for a PSU under load.

The fact that the highest temperature observed at the exhaust is 38.5°C indicates that the PSU is efficiently dissipating heat. A maximum temperature of 42.9°C, which might be mentioned in an accompanying narrative but not visible in the image, would still be considered a good performance for a power supply under heavy load, as PSUs can operate safely at much higher temperatures.

The report of minimal fan noise suggests that the PSU’s fan is effective without needing to spin at maximum speed, which is a testament to the efficiency of the PSU’s cooling system design and the quality of its components. Quiet operation is particularly appreciated in environments where noise levels are a concern, such as in recording studios or quiet office spaces.

Overall, based on the thermal image and the described observations, the COUGAR POLAR X2 1050W appears to be performing within optimal thermal parameters, maintaining a balance between efficient cooling and quiet operation even under the stress of a power-intensive task.

The thermal image shows the rear part of the COUGAR POLAR X2 1050w power supply unit (PSU) during or after a stress test, highlighting the heat distribution. The key temperatures registered on the thermal camera are marked and read as follows:

  1. A spot registering 33.5°C, which is relatively cool and suggests an area away from the main heat-generating components or effective heat dissipation.
  2. Another area shows a temperature of 41.9°C, likely closer to the internal components that generate more heat under load.
  3. A cooler area with a temperature of 26.3°C, which might be a part less affected by the PSU’s heat or more exposed to external cooling.
  4. The highest recorded temperature on the image is 42.9°C, which appears to be near the PSU’s exhaust, where hot air is typically vented out.

The indicated maximum temperature of 42.9°C at the exhaust is within an acceptable range for modern power supplies, especially under load. Power supplies are designed to operate safely at temperatures significantly higher than this, often up to 70°C or more, depending on the model and build quality.

The distribution of heat as seen in the image indicates that the PSU is effectively managing thermal output without overheating, which is essential for maintaining the longevity and reliability of both the PSU and the system it powers. The fact that the highest temperature is found at the exhaust is consistent with expectations, as this is where heat is expelled from the unit, demonstrating that the PSU’s cooling system is functioning correctly.


The COUGAR POLAR X2 1050W power supply unit (PSU) is positioned as a high-end yet ‘ordinary’ PSU, without any flashy or innovative features. Despite this, it achieves high standards in efficiency and noise levels, which are critical aspects for most users. The primary expectations from a PSU are energy efficiency, reliability, and quiet operation, and the POLAR X2 1050W appears to satisfy these criteria effectively.

In terms of cabling, the POLAR X2 1050W provides a somewhat unusual offering of a single CPU 8 Pin cable, diverging from the more common 4+4 pin design, although it does include a 4+4 pin as well. For PCIe connectors, it offers a single 8 Pin cable, which aids in cleaner cable management, though it’s noted that many modern graphics cards require dual 8 Pin connectors, and providing two single 8 Pin cables would have been preferable.

Pricing for the POLAR X2 1050W is listed at NT$ 7290 with a 10-year warranty. Given the ATX 3.0 and 80 PLUS Platinum specifications, the price is considered on the higher side. However, market prices can vary, and there may be opportunities to purchase it at a more favorable rate. Ultimately, the decision to buy will depend on the individual requirements and budget of the user.

Overall, the COUGAR POLAR X2 1050W PSU is a solid performer that meets the essential needs of a high-end PSU, offering stability and reliability for users who require a powerful power supply for their computing needs. The extended warranty period also provides a level of assurance for the long-term investment in this component.
