Comparing Alternatives to Rosewill
Apevia Flex ATX 400W Fully Modular PSU
The Apevia Flex ATX 400W offers a slightly smaller footprint than the Rosewill VIT 500W, measuring 2.9 by 1.4 inches. It sacrifices 100W of maximum power output, making it suitable only for low-power Mini-ITX and Flex ATX systems. Both units are fully modular and feature active PFC for stable voltage regulation. You should choose this Apevia model if space is your primary constraint and your components require less than 400W. It provides similar cable management benefits without the bulk of the 500W Rosewill unit.
Apevia Mini-ITX 500W Fully Modular Power Supply
The Apevia Mini-ITX 500W matches the Rosewill VIT 500W in wattage and modularity. It shares the same compact dimensions of 2.9 by 1.4 inches, which are smaller than the Rosewill's 3.15 by 1.57 inches. Both units utilize active PFC. The Apevia option is ideal if you need full modularity but require a tighter fit within your case. It gives up no power capacity compared to the Rosewill, while offering a marginally more compact physical profile for tight builds.
Apevia Soul 650W Fully Modular PSU
The Apevia Soul 650W is a standard ATX unit, not a Mini ITX form factor. It provides 150W more power than the Rosewill VIT 500W and features a larger 6.2-inch length. This unit is designed for standard gaming cases rather than small form factor builds. It is fully modular and includes active PFC. You should pick this alternative if you are building a standard desktop and need higher wattage. It is not suitable if you require the small 1U or Flex ATX dimensions of the Rosewill.
Rosewill 650W Non-Modular 80+ White PSU
The Rosewill VNW 650W is a non-modular ATX unit, unlike the fully modular Mini ITX Rosewill VIT. It offers 150W more power and uses 80 PLUS White certification. The physical size is larger, at 5.51 inches wide, compared to the 3.15-inch width of the VIT. It retains the 5-year warranty and active PFC. Choose this model if you need more power and do not mind fixed cables. It is a better fit for compact ATX cases where modularity is not a priority.
T.F.SKYWINDINTL 600W Fully Modular Flex ATX PSU
The T.F.SKYWINDINTL 600W is a Flex ATX unit that provides 100W more power than the Rosewill VIT 500W. It shares similar dimensions, measuring 3.27 inches wide and 6.5 inches long. Both are fully modular and use active PFC. The T.F.SKYWINDINTL model is heavier at 2.2 pounds. It is a practical choice for small form factor builders who need higher wattage in a 1U chassis. It offers more power capacity while maintaining the compact size and cable management benefits of the original Rosewill unit.
FSP 220W Mini ITX PSU
The FSP 220W Mini ITX PSU provides significantly less power than the Rosewill VIT 500W. It is designed for low-power systems where energy savings are critical. The unit features active PFC and a compact form factor. However, it lacks modularity, unlike the fully modular Rosewill. You should select this FSP model only if your build requires minimal power and you do not need detachable cables. It is a specialized option for basic Mini ITX systems rather than high-performance builds.
