Corsair iCUE digital monitoring function demonstration

One of the notable features of the Corsair HX1500i power supply is its digital monitoring capability. By connecting the Type-C port on the power supply to the USB 9-pin connector on the motherboard, users can utilize the Corsair iCUE software to access and view various power supply information. This includes details such as fan speed, voltage levels, conversion rates, and power output. Additionally, users have the flexibility to choose between single OCP (Over-Current Protection) or Multi-rail OCP modes, set high-temperature warnings, and utilize other available functions.

While there are numerous software options in the market for checking computer power, their accuracy may be relatively low. With a digital power supply, the internal information is transmitted directly to the computer, resulting in higher accuracy. This allows for comprehensive monitoring of both input and output power. While it is common for users to consider the power consumption of the processor and graphics card as representative of the entire computer’s power, it’s important to note that various components within the computer consume power. Accessing more precise data from the power supply can provide a more accurate overview of power consumption.

Corsair HX1500i Stress Test

In this test, an OCCT power supply stress test is employed to simulate a high power consumption operating environment. The monitoring of the power supply is done using HWiNFO64 software and Corsair iCUE. Furthermore, thermal imaging is used to assess the heating conditions during the test.

The test platform used for this experiment consists of the following components:

  • Processor: Intel Core i7-13700
  • Motherboard: ASUS ROG Strix Z690-E GAMING
  • Memory: Corsair VENGEANCE DDR5-6000 16GBx2
  • Graphics card: Nvidia RTX 4080 16G FE
  • Radiator: 360mm AIO liquid cooling
  • Power supply: Corsair HX1500i
  • Operating System: Windows 11 Pro 22H2

Using the OCCT version 12.0.9 software, a 30-minute stress test is conducted on both the CPU and GPU. According to the OCCT software, the average power consumption of the processor and graphics card combined is approximately 540W. Meanwhile, Corsair iCUE displays that the HX1500i power supply outputs 614W, the socket input is 650W, and the conversion efficiency is calculated to be 94%. These results indicate excellent performance, meeting the Platinum efficiency standards.

During the initial stages of the stress test, the fan of the HX1500i power supply remained idle or stalled. However, after approximately 10 minutes of operation, the fan started spinning. This behavior suggests that the power supply’s internal components are equipped with temperature sensors that detect the temperature levels. Based on this temperature monitoring, the fan is activated to ensure adequate cooling when the internal components reach a certain threshold.

The Corsair HX1500i is a flagship power supply of the new generation ATX 3.0, offering high wattage and appealing features for high-end gamers. Its key attributes include a Platinum efficiency rating and digital monitoring capabilities, which make it highly attractive to enthusiasts.

The iCUE monitoring interface, known for its graphical display, is a notable strength of Corsair. It provides an intuitive and user-friendly experience for monitoring power supply information.

One important feature of the HX1500i is the ZERO RPM mode, which enables the fan to remain idle until the load reaches 50%. This effectively turns it into a fanless power supply with a rating of up to 750W. The 14cm magnetic levitation fan ensures quiet operation, making noise a non-issue. Additionally, the power supply’s fully modular cables help save space and can be replaced with Corsair’s braided module cables, giving users customization options.

Before purchasing the HX1500i, there are two crucial points to consider. Firstly, the size of 200mm may be too tight for some mid-tower cases. However, it’s worth noting that a computer requiring a 1500W power supply is unlikely to be housed in a small case. Secondly, the HX1500i does not fully support all voltage options. For example, in Taiwan, where the household socket delivers a maximum output of 1200W at 110V voltage, achieving the highest output of 1500W would require a 220V voltage. This aspect may introduce some inconvenience in home environments. Ultimately, consumers should carefully consider their specific requirements and choose the most suitable option accordingly.
