Power Supply Seasonic CORE GX 750W 80 Plus Gold ATX 3.1 PCIe 5.0 Fully Modular

Seasonic CORE GX 750W is a mid-high-end ATX power supply aimed at gaming and powerful workstation configurations. With 750W power and 80+ Gold certification, it is suitable for systems with a more serious GPU and multi-core CPU, without worrying about stability. Support for ATX 3.0/3.1 and PCIe Gen 5.0/5.1 means you are ready for modern graphics cards with 12VHPWR. The power supply is in standard ATX format and fits in most mid and full tower cases.

What you get

With efficiency up to 88%, you can expect lower losses and less excess heat compared to more basic power supplies, which is important during long gaming sessions or constant rendering. Active PFC ensures better power factor correction and more stable behavior during fluctuations in the network voltage (from 100 to 240 VAC). Thanks to the rich set of PCI-Express, CPU, and SATA connectors, you can easily power a powerful graphics card, several SSDs/HDDs, and all necessary fans and accessories. A 120mm fan maintains normal temperatures and quiet operation under typical loads. The black design without RGB fits well into minimalist, simpler builds.

• Power 750W – sufficient for strong gaming configurations with modern GPU and multi-core CPU, without risking power shortage.
• 80+ Gold certification and 88% efficiency – less heat loss and more stable operation under higher loads compared to Bronze and lower classes.
• ATX 3.0/3.1 with PCIe Gen 5.0/5.1 – readiness for current and future graphics cards and better compatibility with new platforms.
• 1 x 12VHPWR (12+4) Pin – direct power for modern high-end GPUs without needing several separate adapters.
• 3 x PCI-Express 6+2-pin and 2 x 4+4-pin ATX/EPS – enough connectors for powerful graphics cards and even motherboards with additional CPU power input.
• 6 x SATA and 3 x Molex – flexibility for multiple SSDs, HDDs, fans, and additional accessories in the case.
• Active PFC and 120mm fan – higher quality power supply with better electrical stability and cooling for daily and gaming use.

Who it is suitable for

This power supply is a good choice if you are building a mid-range to high-end gaming PC with a modern GPU, including a PCIe 5.0 model with a 12VHPWR connector. It is also suitable for more serious workstations with multiple drives and additional fans. If you are aiming for a super low budget or an ultra-light office machine, 750W and ATX 3.1 will likely be more than necessary.

The most sensible aspect here is the combination of 750W power, 80+ Gold efficiency, and support for ATX 3.1 / PCIe 5.0 with 12VHPWR, which gives you peace of mind that your power supply will not be a bottleneck for your next upgrades.
