ATX 3.0 PSUs


 Asus ROG Strix 1000W Gold Aura Edition Modular 80+ Gold ATX 3.0 PCIe Gen 5.0 Power Supply

Step into the realm of next-gen power supplies with Overclockers UK’s extensive range of ATX 3.0 power supplies. Designed by Intel, ATX 3.0 PSUs are the beating heart of cutting-edge gaming rigs, perfectly tailored for the latest hardware and crafted to offer incredible performance. Whether you're eyeing the remarkable NVIDIA RTX 40 Series GPUs, Intel 14th Gen CPUs, or AMD Ryzen 7000 Series, ATX 3.0 power supplies are your ticket to top-tier performance. Featuring the groundbreaking 16-pin PCIe 5.0 12VHPWR power connector, capable of delivering a staggering 600W via a single cable, these powerhouses redefine efficiency. What’s more, you can choose from industry-leading brands, including Corsair, Asus ROG, Seasonic, and Kolink.


What are the benefits of an ATX 3.0 PSU

Next-Gen Hardware Compatibility: ATX 3.0 PSUs are engineered to power the latest gaming hardware, including NVIDIA RTX 40 Series GPUs, Intel 14th CPUs, and AMD Ryzen 7000 Series processors.

Efficiency Redefined: With the introduction of a 16-pin PCIe 5.0 12VHPWR power connector, ATX 3.0 PSUs deliver up to 600W through a single cable. This not only simplifies cable management but also enhances power efficiency.

Tackling GPU Power Spikes: ATX 3.0 PSUs are designed to effectively handle GPU power spikes, addressing potential issues of power loss and supply shutdown. They can withstand power spikes of up to 2,600W, ensuring system stability during intense gaming sessions.

Alternative Low Power Mode (ALPM): The inclusion of ALPM settings further enhances efficiency and reduces power consumption. This means that your system can operate more power-consciously, contributing to energy savings without compromising performance.


Do I Need an ATX 3.0 PSU?

If you're looking to power the latest gaming hardware, including NVIDIA RTX 40 Series GPUs, an ATX 3.0 PSU is a great choice! These power supplies are expertly engineered to ensure compatibility with cutting-edge components, deliver enhanced efficiency, and reduce power consumption. Please note, however, that PSUs with over a 450W capacity and no 12VPHPWR power connector can be ATX 3.0 compatible. If you do purchase a new NVIDIA RTX 40 Series GPU, then we recommend that you look for an ATX 3.0 PSU that clearly states it includes a 12VPHPWR connector.
