Gamemax 1000 W GZ 1000G Gold Full Modular Power Supply

Gamemax GZ 1000G is a 1000 W ATX power supply with 80+ Gold certification and a fully modular design, aimed at more serious gaming and high-end configurations. It supports ATX 3.1 & PCIe 5.1 with a native 12V-2x6 connector, so you are covered for current and future high-end GPU models. An efficiency of up to 90% means less heat loss and more stable operation under load. The fan is a 135 mm HDB with a semi-passive 0dB mode, keeping the system quiet under light and medium loads.

What you get

With a real 1000 W output power and Active PFC, this power supply easily handles a combination of a powerful CPU, high-end GPU, and many storage devices. The connectors include 1 x 12V-2x6 (12+4) PCIe 5.1 and 4 x 8-pin (6+2) PCIe, allowing power for modern graphics cards and multi-GPU scenarios or one power-hungry card plus plenty of peripherals. 10 x SATA, 3 x Molex, and 1 x FDD provide enough flexibility for a case with many SSDs, HDDs, and accessories. Japanese bulk capacitors rated at 105°C and matrix-arranged solid capacitors reduce ripple and help extend component life. The semi-passive mode with fan-off at low load keeps the PSU completely silent in idle and under light work, while the intelligent temperature control smoothly increases the RPMs under more serious load.

• Power 1000 W with 80+ Gold efficiency up to 90% – suitable for high-end systems with powerful GPUs and plenty of additional hardware.
• ATX 3.1 & PCIe 5.1 ready with native 12V-2x6 connector – ready for the latest graphics cards without the need for adapters.
• Fully modular design with embossed flat cables – connect only what you need, cable management becomes easier, airflow in the case is better.
• 135 mm HDB fan with semi-passive 0dB mode – the fan stops at low load for absolute silence and smoothly turns on as the temperature rises.
• Rich set of connectors – 1 x 24-pin ATX, 2 x 8-pin (4+4) CPU, 1 x 12V-2x6 PCIe 5.1, 4 x 8-pin (6+2) PCIe, 10 x SATA, 3 x Molex, and 1 x FDD cover complex configurations.
• Japanese bulk capacitors rated at 105°C and matrix-arranged solid capacitors – lower ripple and more stable voltage under load.
• Two-stage EMI filtering and a full suite of protections (OPP / OVP / OCP / OTP / UVP / SCP) – protection for components against overload, overvoltage, short circuits, and high temperatures.

Who it is suitable for

This power supply is suitable if you are planning a serious gaming or workstation build with a modern PCIe 5.x graphics card, overclocked CPU, and plenty of storage/accessories. It is also appropriate if you are looking long-term – ATX 3.1 standard and stable capacitors for years to come. More modest office or budget configurations simply will not utilize the potential of 1000 W and the rich PCIe options.

The combination of high power, ATX 3.1 / PCIe 5.1 support, and fully modular design makes Gamemax GZ 1000G a very sensible choice for future upgrades. The most impressive aspect is the flexibility – from quiet operation in idle to stability under heavy gaming or rendering load.
