Introducing GameMax’s GS SFX Gold Series

If you’re in the market for a new power supply unit (PSU) that doesn’t just promise power but delivers on performance, you might want to check out the latest offering from GameMax. This emerging brand has just rolled out its GS SFX Gold Series power supply units, and they’re packing some serious tech under the hood. With compliance to the latest ATX 3.1 and PCIe 5.1 standards, these PSUs are designed to keep your gaming rig running smoothly and efficiently.

Tailored for Gamers

What’s particularly exciting about the GS SFX Gold Series is its native support for the latest nVidia RTX Graphics Cards, thanks to the 12V-2×6 connectors. Whether you’re building a high-performance gaming setup or just upgrading your existing system, these power supplies come in three wattage options—650 W, 750 W, and 850 W—so you can find the perfect fit for your needs. Plus, they’re available in sleek black and white options, making it easy to match them with your overall aesthetic.

Performance Meets Innovation

Under the hood, the GS SFX Gold Series is no slouch. With advanced features like Active PFC, Half-Bridge LLC Resonance, and Synchronous Rectification, these PSUs are engineered for high performance and efficiency, particularly on the crucial +12V rail that powers your graphics card. But what does this mean for you? Essentially, you get a smoother gaming experience with less lag and more power when you need it.

And let’s not forget about noise—who wants a power supply that sounds like a jet engine? The GS SFX Gold Series includes a smart microcontroller, the FMD-F161E131B, which manages the fan’s operation intelligently. This means the fan can actually stop spinning when your load is below 20%, giving you that coveted 0 dBA operation for silent gaming.

Efficiency at Its Best

You might be wondering about energy consumption. The GS SFX Gold Series boasts an impressive 80 Plus Gold certification, ensuring that it converts over 90% of the power it draws into usable energy. This not only helps you save on electricity bills but also contributes to a greener planet. Who doesn’t want to be eco-friendly while gaming?

Built to Last

Quality matters, especially when it comes to gaming. That’s why GameMax has equipped the GS SFX Gold Series with top-notch 105°C Japanese capacitors. These components are designed to provide stable and reliable power, which is crucial for those marathon gaming sessions. And with a low-noise Hydraulic Bearing (HDB) fan that boasts a lifespan of up to 40,000 hours, you can count on this PSU to stick around for the long haul.

Aesthetics and Protection

Let’s face it: cable management can be a nightmare. Thankfully, the fully modular design of the GS SFX Gold Series minimizes cable clutter. The 12V-2×6 cable even comes with a 90° angled connector, making your setup cleaner and more manageable. And for peace of mind, this PSU is loaded with comprehensive protection features, including OVP, UVP, OPP, OCP, SCP, OTP, and SIP. It also meets multiple certifications, including CB, TÜV, CE, and FCC, so you know it’s built to last.

PSU: A Power Supply Unit (PSU) is an essential component of any computer system. It is responsible for providing the necessary power to the components of the computer. It converts the alternating current (AC) from the wall outlet into the direct current (DC) that the computer components need. The PSU also regulates the voltage and current to ensure that the components are not damaged by too much or too little power. The PSU is also responsible for providing the necessary cooling to the components, as well as protecting them from power surges. In the computer industry, PSUs are used in desktop computers, laptops, servers, and other electronic devices. They are also used in gaming consoles, home theater systems, and other consumer electronics.

SFX: "SFX," or Small Form Factor, in computing refers to a type of power supply designed to fit into smaller computer cases, particularly those associated with Mini-ITX or Micro-ATX form factors. These power supplies are smaller than standard ATX units, making them ideal for compact builds where space is limited. SFX power supplies are commonly utilized in Mini-ITX cases due to their smaller size compared to traditional ATX power supplies, enabling efficient use of available space.
