Who it fits
Good fit for
This power supply suits gamers building entry-level to mid-range systems. You will appreciate the 550 watt capacity if your GPU and CPU do not demand excessive power. The non-modular design is ideal for cases with good airflow where cable management is less critical. If you want a straightforward install without managing separate cable bundles, this unit fits your needs. The 80 PLUS rating helps keep electricity costs lower over time. It is a practical choice for users who value stability and simplicity over advanced customization.
Who should skip it
You should look at another option if you need high efficiency beyond the 80 PLUS standard. This unit does not offer Gold or Platinum ratings, so power users seeking maximum efficiency will find it lacking. The non-modular design may not suit tight cases where cable clutter is a major concern. If you require silent operation under heavy loads, the 120 mm fan might not be quiet enough for your preference. Additionally, users needing more than 550 watts for high-end hardware will find this power insufficient for their setup.
Verdict: The Enermax MAXPRO IV 550W is a solid, no-frills power supply for standard gaming builds. It offers reliable efficiency and straightforward installation for users who do not need modular flexibility.
Enermax MAXPRO IV Key Specs
Wattage: 550 Watt
This rating indicates the maximum continuous power the unit can deliver to your components. You can use this figure to ensure your CPU and graphics card stay within safe limits. It suits mid-range gaming PCs or standard office builds that do not require extreme power headroom for heavy overclocking.
Efficiency Rating: 80 PLUS
This certification confirms the unit converts at least 87% of input AC power into usable DC power at 230VAC. Higher efficiency means less wasted energy as heat and slightly lower electricity bills. You benefit from a cooler-running system and reduced strain on internal components compared to non-certified units.
Modularity: Non-Modular
All cables are permanently attached to the power supply unit. You cannot detach or swap individual cables. This design simplifies installation for beginners since you do not need to manage cable connections, but it requires more case space for cable routing and management inside your chassis.
Fan Size: 120 mm
The cooling fan measures 120 millimeters across. Larger fans generally move more air at lower speeds, which reduces audible noise during operation. This size helps keep internal temperatures stable while maintaining a quiet environment, making it suitable for users who prefer a silent desktop experience during gaming or work.
ATX Version: ATX12V v2.4
This version number indicates compliance with specific industry standards for power delivery and connector layouts. It ensures the unit works correctly with modern motherboards and supports advanced power-saving features like C6 and C7 states. You get reliable compatibility with recent Intel processors and standard desktop platform designs.
Build Quality and Physical Design
The Enermax MAXPRO IV 550W measures 5.91 inches wide, 3.39 inches high, and 5.51 inches long. It weighs 2.87 pounds. These dimensions fit standard ATX cases.

This material aids airflow and gives a cleaner look inside your chassis. You do not need to buy separate cable extensions.
According to the listing, the unit uses premium Japanese main electrolytic capacitors. These components support stable power delivery and durability. The power supply operates continuously at 40°C ambient temperature. This thermal rating ensures reliable performance during heavy workloads. The 120 mm fan provides quiet cooling. This size balances airflow and noise levels effectively for most users.
The finish is black, matching standard case interiors. The unit complies with ATX12V v2.4 standards. It includes multi-protection circuits against short circuits, over-voltage, undervoltage, and overload. These safety features protect your components from electrical faults. The automatic 100-240VAC input allows worldwide use without manual switches. This design choice adds convenience for travelers or those buying imported parts. The overall build focuses on stability and ease of use rather than premium aesthetics.
Setup and Daily Use
Setting up this power supply involves standard installation steps. The unit measures 5.91 inches wide, 3.39 inches high, and 5.51 inches long. These dimensions allow it to fit into most standard ATX cases. Because it is non-modular, all cables are fixed to the unit. You must route the entire harness through your case. The individual mesh-sleeve cables help with cable management. They allow for a cleaner look inside the chassis. This design simplifies the initial build process by removing the need to manage separate cable connections.
Compatibility is straightforward. The unit complies with Intel ATX12V v2.4 standards. It supports C6 and C7 energy-saving features for Intel processors. This ensures it works well with modern desktop platforms. The automatic 100-240VAC input means you can use it worldwide without voltage adjustments. Active power factor correction is listed at up to 0.99. This helps maintain stable power delivery across different electrical grids.
Daily use focuses on stability and noise. The 120 mm fan provides continuous cooling. The manufacturer states this results in quiet operation. This is important for gaming setups where background noise matters. The unit is rated for non-stop operation at 40°C ambient temperature. This suggests it can handle sustained loads without overheating. Multi-protection circuits guard against short circuits, over-voltage, undervoltage, and overload. These features protect your components during unexpected power events. The 80 PLUS rating confirms efficient energy conversion. This reduces waste heat during everyday computing tasks.
Before you buy this PSU
Before you buy, check your case compatibility. This unit measures 5.91 inches wide, 3.39 inches high, and 5.51 inches long. These dimensions fit standard ATX cases. Ensure your chassis has enough room for a 120 mm fan. The non-modular design means all cables are fixed. You must manage these cables carefully during installation. The mesh-sleeve harness helps with aesthetics and airflow. Verify your motherboard supports ATX12V v2.4. This standard ensures proper power delivery for your CPU and components. The unit includes safety protections like over-voltage and short-circuit safeguards. These features protect your hardware from electrical faults. Consider your total system power draw. The 550-watt rating suits mid-range builds. If you plan to upgrade your graphics card later, check if this wattage remains sufficient. This power supply fits alongside other options in PC Power Supplies & UPS by offering steady performance for standard desktops. It prioritizes efficiency and safety over modularity. This approach keeps the design simple and reliable for users who do not need custom cable lengths.
Check before you buy
- Verify your ATX case fits the 5.91 by 3.39 by 5.51 inch dimensions.
- Check that your motherboard supports the ATX12V v2.4 standard.
- Ensure your system power draw stays under the 550-watt limit.
- Plan cable management for the fixed non-modular harness.
