1100W! SFX size! CoolerMaster V 1100 SFX Platinum unboxing

The CoolerMaster V 1100 SFX Platinum sets a new benchmark in the consumer market for power supply units (PSUs) with its impressive power density of 22.7 watts per cubic inch. This figure notably surpasses the brand’s own SFX Gold 850W model by 30%, illustrating a significant leap in efficiency and compact power delivery. The high power density is a direct result of the premium materials and cutting-edge technologies used in its construction. These include all-Japanese capacitors, full-bridge LLC, active power correction, DC-DC technology, and the utilization of thermal conductive patches and metal sheets for enhanced heat dissipation. This PSU has earned the prestigious Platinum certification from both 80 PLUS and Cybernetics, and it also meets the Intel ATX3.0 standards.

In terms of design, the CoolerMaster V 1100 SFX Platinum features a fully modular cabling system. The power supply module connector extends just 9mm, optimizing space usage and ensuring compatibility with most ITX cases, despite its uniqueness in the market. Notably, this model omits the common power switch found on the rear of many PSUs, a decision that underscores the emphasis on maximizing space efficiency in its design.

This paraphrasing focuses on the high power density and advanced technological features of the CoolerMaster V 1100 SFX Platinum, while also highlighting its design elements and certifications, which are key for SEO optimization and informative content creation.

The CoolerMaster V 1100 SFX Platinum is equipped with a 92mm FDB (Fluid Dynamic Bearing) liquid-bearing fan, renowned for its quiet operation. Unlike some models, this power supply unit (PSU) does not feature a low-temperature shutdown function, which could be attributed to the thermal management challenges inherent in smaller-sized PSUs. Remarkably, when operating under a load of 40% or less, the fan maintains a low speed of approximately 1500 RPM. This low rotational speed contributes to its exceptionally quiet performance, ensuring that the noise level remains negligible even during periods of high-load operation. This design choice underscores the PSU’s ability to balance efficient cooling with minimal noise, making it an appealing choice for users who prioritize a quiet computing environment.

This paraphrasing emphasizes the quiet cooling efficiency of the CoolerMaster V 1100 SFX Platinum, focusing on the fan’s specifications and operational characteristics, which are essential for users interested in both performance and acoustics. This detailed explanation is beneficial for SEO and consumer understanding.

The CoolerMaster V 1100 SFX Platinum power supply unit (PSU) features a fully modular design, enhancing both aesthetic appeal and functional ease. A standout aspect of its cabling is the unique 12VHPWR connector, encased in a network-style cover. This contrasts with the other cables, which are uniformly black and flat, simplifying cable management and navigation through tight spaces within a computer case. Notably, the 12VHPWR cable is equipped with a 90-degree connector, a thoughtful design choice aimed at preventing wire bending issues in compact chassis. A protective frame is incorporated to prevent pin withdrawal, significantly enhancing electrical safety.

The PSU’s cable set includes a variety of connectors to accommodate different components:

  • 1 ATX/MB 20+4 Pin connector (30cm length)
  • 1 CPU/EPS 4+4 Pin connector and 1 8 Pin connector, each 45cm long
  • 1 PCIe 12+4 Pin (12VHPWR) connector (40cm length)
  • 3 strips, each with a PCIe 6+2 Pin connector (40cm length)
  • 2 strips, totaling 8 SATA connectors (lengths of 10cm, 15cm, 15cm, and 15cm)
  • 1 strip with 4 large 4-pin connectors (lengths of 10cm, 12cm, 12cm, and 12cm)

80 PLUS Platinum Certification | CoolerMaster V 1100 SFX Platinum Stress Test

This evaluation employs the OCCT, a widely recognized tool for stability checks and stress testing, to create a high-power usage scenario. It also utilizes HWiNFO64, known for its comprehensive hardware analysis and monitoring capabilities in both Windows and DOS environments, to accurately record voltage and power metrics. The FLIR ETS320 thermal imaging system is employed for its ability to conduct non-contact thermal measurements. This system is especially sensitive, detecting minute temperature changes (less than 0.06°C) and capable of measuring heat generation up to 250°C. With its 76,800 points of non-contact measurement and an accuracy of ±3°C, it enables precise identification of hot spots in electronic components such as printed circuit boards, without being affected by heat sinks

The testing setup included:

  • CPU: Intel Core i9-14900K
  • Mainboard: ASUS ROG Strix Z790-A GAMING WIFI II
  • Cooling: Lianli GALAHAD II PERFORMANCE 360 Radiator
  • PSU: CoolerMaster V 1100 SFX Platinum
  • OS: Windows 11 Pro 23H2

The system underwent a 30-minute OCCT 12.1.10 power supply stress test. Results indicated CPU consumption at 369W and GPU at 314W, totaling approximately 683W. A power meter reading showed around 770W. HWiNFO64 documented stable average voltages: +12V at 12.077V, +5V at 4.961V, and +3.3V (3VCC) at 3.330V.

Approximately 27 minutes into the power supply stress test, thermal imaging was used to monitor the temperature of the CoolerMaster V 1100 SFX Platinum. The highest temperature recorded for the power supply was 66.5 degrees Celsius. In contrast, the temperature at the 12VHPWR connector of the graphics card was a much cooler 42 degrees Celsius, indicating excellent performance. Notably, the sound emitted by the power supply’s fan was relatively quiet, especially when compared to the more noticeable noise levels from the water cooling system and the graphics card fans.

The CoolerMaster V 1100 SFX Platinum stands unparalleled in the market, boasting a unique combination of 1100W power, SFX form factor, and ATX 3.0 compatibility. Its lack of direct competitors, even among SFX-L models of similar wattage, makes it a singular choice for high-power ITX builds.

Drawing from personal experience with ITX hosts, I recommend opting for higher wattage SFX power supplies. ITX cases generally have less efficient heat dissipation, and the 92mm fans typically used in SFX units are noisier compared to the 120mm or 140mm fans in ATX units. A higher wattage ensures greater stability and reduced noise.

CoolerMaster has innovatively modified the 12VHPWR connector to minimize burnout risks. The 90-degree adapter is both space-saving and aesthetically pleasing. The anti-removal pin design enhances safety, necessitating users to securely fasten the connector. These thoughtful enhancements significantly improve the overall safety of the unit.
