Gamemax Power Supply 550W MAX P550B Bronze Non-Modular

Gamemax MAX P550B is a 550 W ATX power supply with 80+ Bronze certification, aimed at budget and mid-range gaming and office configurations. You get internal ATX12V power for PC with active PFC and efficiency up to ≥88% at 50% load, which helps keep consumption and temperatures under control. The model is not modular, but comes with enough connectors for modern systems, including two PCIe cables for a graphics card. The combination of 100% Japanese electrolytic capacitors and DC-to-DC topology makes it a quite solid choice for stable operation in the long term.

What you get

With real 550 W output power and 45.8 A on the +12 V rail, this power supply comfortably covers a typical gaming build with a modern CPU and one graphics card with two PCIe power connectors. Technologies Active PFC + Double forward + DC-to-DC help with more stable voltages and better efficiency at different load levels, which is important during sudden spikes in consumption during gaming or rendering. Full compatibility with Intel ATX 3.1 and support for up to 200% system / 300% GPU power excursions mean the power supply is prepared for modern short-term power peaks of graphics cards. 120 mm Hydro Bearing fan ensures quieter operation and longer life compared to a standard sleeve bearing, which is especially noticeable during prolonged gaming. Add to that the wide input range 180–264 V (up to 160 V transient), which gives additional security during fluctuations in mains voltage.

• 550 W Power with 45.8 A on +12 V, sufficient for mid-range gaming or work configuration with one powerful graphics card.
• 80+ Bronze efficiency with ≥88% at 50% load, which reduces losses as heat and keeps the system cooler and more economical.
• Full compatibility with Intel ATX 3.1 and support for 200% system / 300% GPU power excursions for reliable operation with modern GPUs with high short-term peaks.
• Active PFC + Double forward + DC-to-DC topology for more stable voltages and less risk of instability when changing the load.
• 100% Japanese electrolytic capacitors (Rubycon, NCC, Nichicon), designed for longer life and better stability at higher temperatures.
• 120×120×25 mm Hydro Bearing fan for quieter operation and long life, suitable for systems that work for hours under load.
• Rich connector set: 1× 20+4-pin ATX, 2× 8-pin (4+4) EPS, 2× 6+2-pin PCIe, 3× SATA, 1× Molex, covering a typical gaming configuration and several storage devices.
• Full protection OPP/OVP/SCP/OTP/OCP/UVP/SIP/NLO and compliance with IEC 62368-1:2018 and multiple certifications (CE, TÜV-SÜD, RCM, etc.) for higher security.
• Compact dimensions 140 × 150 × 86 mm in standard ATX format and classic black color without RGB for a clean build.

Who is it suitable for

This power supply is suitable if you are building a budget or mid-range gaming PC, office or home workstation and want something above "no-name", but without paying for unnecessary luxury. A good choice if you plan one graphics card with up to two PCIe connectors and do not chase extreme overclocking. It is not the best option if you are thinking about a multi-core HEDT CPU or top high-end GPU that requires higher wattage and more PCIe power supplies.

The most sensible here is the combination of 550 W, 80+ Bronze efficiency, ATX 3.1 compatibility and Japanese capacitors in standard ATX format. You get a balanced package of stability, security and real practicality for daily gaming and work.
