Asrock PG-1300G 1300W 80 Plus Gold ATX 3.1 PCIe 5.1 Cybenetics Fully Modular PSU

Asrock PG-1300G is a powerful 1300W ATX power supply aimed at high-end gaming and workstation configurations, where stability under load is key. The 80+ Gold certification and declared 90% efficiency mean lower losses, less heat, and quieter operation under normal load. Support for ATX 3.0/3.1 and PCIe Gen 5.0/5.1 makes it ready for current and future high-end GPU cards. The fully modular design and compact dimensions for this class provide freedom in cable management even in more tightly assembled cases.

What you get

With a power of 1300W, you have a serious reserve for combinations with top GPUs and multi-core CPUs, even during overclocking and long gaming or rendering sessions. The two PCIe 5.1 (12+4pin) connectors allow you to directly power current graphics cards without the need for adapters, while a total of 6 PCIe (6+2pin) connectors cover multi-GPU, capture cards, or more power-hungry expansion cards. With 9 SATA and 3 Molex (4-pin Peripheral) connectors, you can easily cable several SSDs, an HDD array, a fan hub, and additional accessories. The 135mm FDB fan (Fluid Dynamic Bearing) provides quieter and longer-lasting operation compared to regular sleeve or ball bearing solutions, which is important for long uptime. Active PFC and input 100–240 VAC ensure stable operation across a wide range of electrical networks, which is a plus if your power is not ideal.

• Power 1300W — sufficient for high-end GPU + powerful CPU, with good headroom for future upgrades and overclocking.
• 80+ Gold certification and 90% efficiency — less heat loss, lower power consumption, and quieter operation under typical load.
• ATX 3.0/3.1 and PCIe Gen 5.0/5.1 support — ready for modern and next-generation graphics cards and platforms.
• 2 x PCIe 5.1 (12+4pin) + 6 x PCIe (6+2pin) — flexibility for powering one or more powerful graphics cards and additional cards.
• 9 x SATA and 3 x 4-pin Peripheral — enough connectors for many SSDs/HDDs, fans, and peripherals in a more serious build.
• Fully modular design — connect only the necessary cables, which simplifies cable management and improves airflow.
• 135mm FDB fan — quieter operation and better durability under long-term load.
• 60 months warranty — long-term coverage for a component on which the entire configuration depends.

Who it is suitable for

This power supply is suitable for high-end gaming and professional configurations with one or more powerful graphics cards, plenty of storage, and long hours under load. If you are building a brutal setup with a current PCIe 5.x GPU and want serious power headroom and modern connectors, the PG-1300G fits perfectly into this scenario. For more modest systems with entry or mid-range GPUs, this power is more of an unnecessary luxury.

The combination of 1300W power, 80+ Gold efficiency, and ATX 3.1 with PCIe 5.1 connectors makes the Asrock PG-1300G power supply a solid choice for planning not only your current but also your next high-end build.
