This power supply features a full range active PFC that operates on 90-264V AC, making it suitable for various regional power supplies. It comes equipped with multiple connectors, including a 20+4 pin main power, an 8-pin 12V connector, and various PCIe and SATA options to support different components. The Apevia unit also incorporates a 40mm double ball bearing fan for cooling and includes several protection features, ensuring the safety and reliability of the system.

Overview of the Rosewill VMG 850W

The Rosewill VMG 850W is a robust power supply that stands out with its 80+ Gold certification, ensuring high energy efficiency. At $74.97, it is about 50% more expensive than the Apevia ITX-PFC500W. However, this cost is justified by the increased power output of 850W, which allows for greater capacity when powering high-performance components, particularly in gaming or workstation setups.

This power supply is fully modular and features compatibility with ATX 3.0 and 3.1 standards, making it future-proof for next-generation hardware. The Rosewill model also includes a PCIe 5.1 12V-2x6 cable, which supports the latest graphics cards, providing up to 600W of direct power. With a 120mm FDB silent fan, it emphasizes low-noise operation while ensuring efficient cooling, further enhancing its appeal for users seeking a quiet computing environment.

Build Quality and Design

In terms of build quality, both the Apevia ITX-PFC500W and Rosewill VMG 850W present solid designs tailored to their respective market segments. The Apevia's compact dimensions of 160mm x 73.66mm x 35.5mm make it an excellent choice for space-constrained builds, while its 40mm fan ensures adequate cooling without taking up excessive space.

Conversely, the Rosewill VMG 850W features a slightly larger chassis at 140mm x 150mm x 86mm. This design accommodates a larger 120mm fan for improved airflow, which is necessary for handling the increased power output. Both units are equipped with multiple safety features, including overvoltage and short circuit protection, but the Rosewill's six-protection suite provides an additional layer of security, which may appeal to users planning to run high-end components.

Efficiency and Performance

The efficiency ratings of these power supplies differ significantly, impacting their performance and operational costs. The Rosewill VMG 850W boasts an 80+ Gold certification, which indicates that it operates at an efficiency of at least 87% under typical loads. This efficiency not only translates to lower electricity bills but also less heat generation, enhancing the longevity of the components.

In contrast, the Apevia ITX-PFC500W does not have a specific efficiency rating mentioned but features a full range active PFC for stable operation. While it will perform adequately for low to mid-range systems, users running high-performance rigs may find the Rosewill's efficiency and higher wattage more beneficial. Thus, for users prioritizing performance and efficiency, the Rosewill power supply stands out.

Connectivity Options

The connectivity options provided by each power supply cater to different user needs. The Apevia ITX-PFC500W comes with essential connectors, including one 20+4 pin main power connector, one 8-pin 12V connector, two 6+2 PCIe connectors, and various SATA and Molex connectors. This makes it suitable for basic to mid-range builds, especially in compact cases.

On the other hand, the Rosewill VMG 850W offers a more extensive array of connections. Its dedicated PCIe 5.1 12V-2x6 cable supports the latest graphics cards, delivering up to 600W directly to the GPU. This feature makes it particularly appealing to gamers and professionals who require significant power for demanding applications. Additionally, the full modular design of both units allows for customized cable management, which enhances airflow and aesthetics.

Noise Levels

Noise levels can be an important consideration, especially for users who build quiet systems. The Apevia ITX-PFC500W features a 40mm double ball bearing fan, which can be effective but may produce higher noise levels under load due to its smaller size. Users should be mindful that while it is adequate for basic systems, it may not be the quietest option for more demanding setups.

In contrast, the Rosewill VMG 850W utilizes a 120mm FDB silent fan, designed to minimize noise while maximizing cooling efficiency. This fan is likely to operate at lower RPMs compared to the smaller fan in the Apevia unit, resulting in a quieter overall system, which is particularly desirable for users who prioritize a silent operating environment.

Price and Value

When considering price, the Apevia ITX-PFC500W is priced at $49.99, making it a budget-friendly option for those building basic or compact systems. Its lower price point (approximately 33% less than the Rosewill) makes it an attractive choice for users who do not require high wattage or advanced features.

However, the Rosewill VMG 850W, while more expensive at $74.97, offers superior performance, higher efficiency, and a wider range of features that justify the additional cost. For users planning to run high-performance components or future-proof their builds, the investment in the Rosewill power supply may provide better long-term value.

Which should you buy?

In conclusion, the choice between the Apevia ITX-PFC500W and the Rosewill VMG 850W largely depends on your specific needs and budget. If you are building a compact, budget-friendly system with moderate power requirements, the Apevia unit is a solid option. However, for those looking for a more powerful, efficient, and quieter power supply capable of supporting high-performance components, the Rosewill VMG 850W is the superior choice. Ultimately, consider your current and future hardware needs to make the best decision for your build.
