As the next generation graphics cards with 12VHPWR power connectors are getting closer and closer, more and more power supply manufacturers are rolling out ATX 3.0 products. Seasonic still has to officially announce its ATX 3.0 PSUs, but many North American retailers are already listing these parts. So far we’ve seen his ATX 3.0 power supplies that are pretty pricey, but Seasonic’s PS Vertex lineup will include models for around $230.
Seasonic’s PS Vertex ATX 3.0 power supply family includes four SKUs. @momomo_usThese PSUs are now listed in numerous US and Canadian stores including: Provantage When Tech Americaand prices range from $231.23 to $304.78.
Seasonic’s PS Vertex ATX 3.0 PSU for enthusiasts is fully modular and equipped with a large fan to ensure stable performance under heavy loads. The main selling point of these power supplies is the 12VHPWR connector for next generation graphics cards.

AMD and Nvidia’s upcoming graphics cards (which are set to be their best graphics cards) are expected to use the ATX 3.0 standard 12+4 pin auxiliary PCIe 5.0 power connector called 12VHPWR. Based on its needs and PSU capabilities (150W, 300W, 450W, or 600W, depending on application). The 12VHPWR uses 12 pins for power delivery, while the remaining 4 pins carry sideband signals such as detection of the connector/PSU’s initial and maximum allowed power. These sideband signals are implemented to prevent add-on cards from consuming power beyond certain limits and burning out the PSU.
Seasonic’s PS Vertex 1000W 80 Plus Gold is the cheapest ATX 3.0 power supply we’ve seen so far, but there’s no doubt that more affordable options will emerge as the standard takes hold. On the other hand, keep in mind that these PSUs are designed to power add-on cards up to 600W. These are high wattage power supplies and are priced accordingly.
