“The 12VHPWER connector on this power supply is marked with a 450W capacity, which theoretically supports the RTX 4090 GPU. However, this might be a close call in terms of power headroom. For cautious gamers like myself, opting for a more robust solution is preferable. I recommend choosing a power supply unit with at least a kilowatt capacity and a 12VHPWER connector that guarantees 600W of power. This provides a more secure and reliable power source for high-end gaming setups, especially when running a demanding GPU like the RTX 4090.

Cooler Master V850 SFX GOLD Power supply test

Paired with RTX 4060 Ti and 12VHPWER special 90-degree connector cable.

Our test platform, powered by Intel, included the following high-end components:

  • Processor: Intel i7-12900 K
  • Motherboard: ASRock Z790 Taichi
  • Cooling Solution: PHANTEKS GLACIER ONE 240 T30
  • Graphics Card: NVIDIA GeForce RTX 4060 Ti
  • Operating System: Windows 11 Professional, version 21H2
  • Power Supply: Cooler Master V850 SFX GOLD

In a rigorous OCCT power stress test that lasted 30 minutes, we observed the CPU’s power consumption stabilizing at approximately 228W, while the RTX 4060 Ti GPU consumed 159W. The combined power usage of these two components stayed below 400W, demonstrating efficient power management. However, when we measured the total power consumption of the entire system under stress, it averaged around 537W. This result underscores the ample capacity of the Cooler Master V850 SFX GOLD, which handled the load with ease. Notably, even under high power output, the power supply’s fan noise was minimal, almost indistinguishable amidst the ambient noise of other cooling systems in operation. Overall, the noise level of the power supply was impressively low.

During an intensive 30-minute stress test using both FurMark and AIDA64 to simultaneously push the GPU and FPU to their limits, we recorded some interesting observations about the power supply’s performance. The +12V output voltage showed a slight decrease, averaging at 11.737V, which is slightly below the optimal 12V. However, the average output voltages for both the +5V and +3.3V rails remained well within normal ranges. This indicates a stable performance under extreme conditions, although the slight dip in the +12V rail is noteworthy.

Kuma is making significant strides in addressing the increasing demand for compact PC cases. They’re investing in the development of smaller cases and focusing on creating power supplies that are not only efficient and lightweight but also come with a ten-year warranty. The V850 SFX Gold is a prime example of their commitment to quality. It features a 92mm smartly controlled silent bearing fan, which adeptly adjusts its speed in line with power consumption. This makes it an ideal choice for gamers who prioritize a quiet setup in their small chassis.

Despite its reduced size, the V850 SFX Gold doesn’t compromise on the details and quality typical of high-end power supplies. It boasts a configuration of 100% Japanese capacitors. As the demand for 12VHPWER grows, noticeable enhancements have been made in the wire interface, and even the aesthetic design of the power supply has received attention. This product is designed to appeal to enthusiasts of small case DIY projects, as well as those who are drawn to the Cooler Master V850 SFX’s sleek appearance.

Furthermore, it comes with a conversion bracket, offering flexibility for ATX users. In summary, this high-efficiency SFX power supply is gaining popularity due to its decade-long warranty and attractive design. It’s an excellent option for those interested in building a mini-ITX setup and is worth considering for anyone ready to dive into their next PC build project.
