Power supply Seasonic CORE GX White 750W 80 Plus Gold, Fully Modular, ATX 3.1, PCIe 5.1

Seasonic CORE GX White 750W is a 750-watt ATX power supply aimed at mid-range to more serious gaming and creative configurations. It combines 80+ Gold certification with up to 90% efficiency, which means less energy loss and lower heat under load. The power supply is in white color, making it a logical choice for a white build with a transparent panel. It supports ATX 3.0/3.1 - PCIe Gen 5.0/5.1, so you are covered for newer GPU generations.

What you get

With a power of 750W, you have enough resources for a modern CPU and a strong GPU, plus additional devices and peripherals. Active PFC helps for more stable power supply and better performance under various voltages in the network – especially useful if your power is not perfectly stable. The connectors include both the classic PCI-Express 6+2-pin for older or mid-range cards, as well as 12V-2x6 for newer and more power-hungry GPUs. A 120 mm fan handles cooling, ensuring the power supply operates reliably under prolonged load. The power supply accepts an input voltage of 100 - 240 VAC, giving it flexibility for various electrical installations.

• Power 750W – sufficient for a serious gaming or workstation build with a powerful GPU and several additional devices.
• 80+ Gold certification and up to 90% efficiency – less loss as heat and lower consumption compared to lower-class power supplies.
• ATX 3.0/3.1 and PCIe Gen 5.0/5.1 support – ready for modern and future graphics cards, without the need for adapters.
• Connector 1 x 12V-2x6 + 2 x PCI-Express 6+2-pin – covers both new high-end GPUs and older/mid-range graphics cards.
• 2 x 4+4-pin ATX/EPS – provides stable power for modern CPUs, including platforms with higher consumption.
• 6 x SATA and 3 x Molex – enough connections for SSDs, HDDs, fans, and additional accessories in the case.
• 120 mm fan and Active PFC – a combination for more stable operation and more reliable cooling under prolonged load.

Who it is suitable for

This power supply is suitable if you are building a gaming or productivity computer from mid to high class, especially if you want to be prepared for PCIe 5.0/5.1 graphics cards. It is also a good choice if you are aiming for a clean white build and care about higher energy efficiency. If you plan on extreme multi-GPU or heavily loaded workstation with many devices, you might want to look towards higher power.

The most sensible aspect here is the combination of 750W power, 80+ Gold efficiency, and support for ATX 3.0/3.1 with 12V-2x6, which gives you peace of mind that the power supply will not be a bottleneck when upgrading to newer GPU generations.
