VERTEX PX
The new VERTEX Series units will provide 1200 W / 1000 W / 850 W and 750 Watts of true power in Platinum level of efficiency, with all the best features you can expect from a Seasonic power supply:
- Fully compatible with ATX 3.1 and PCIe 5.1 standards.
- Full modularity for the best cable management options.
- Added 12V-2×6 cable to comply with the new graphic cards.
- 135mm Fluid Dynamic Bearing (FDB) fan for quiet operation.
- Seasonic Hybrid Silent Fan Control for optimal cooling.
- Complete protection features: OPP / OVP / UVP / SCP / OCP / OTP.
- 12 years warranty – our commitment to high quality.
Note: Seasonic VERTEX Series PSUs were initially shipped with 12VHPWR cables. Following the ATX standard update, we transitioned to 12V-2×6 connectors. During this period, customers may receive either cable, depending on the region. The updated VERTEX version is expected later in 2025 for Europe and North America. We apologize for any inconvenience.

VERTEX PX ATX 3.1
ATX 3.1 and 16-Pin PCIe Gen 5.1 Cable (12V-2x6)
Seasonic’s latest VERTEX ATX 3 Series is designed and built to power new PC components requiring the new ATX 3.1 and PCIe 5.1 standards.
Micro Tolerance Load Regulation
Seasonic’s latest design keeps the output voltage within a very tight range, achieving under 0.5 % load regulation. This impressive electrical performance and stability makes this power supply an ideal choice for high-performance systems.

Digital Hybrid Fan Control
Seasonic’s vast experience in designing the most silent and efficient power supplies on the market was translated into the development of Hybrid Mode; a state-of-the-art digital fan control that enables users to keep the overall fan noise at the lowest possible level.
Note: The Digital Hybrid Fan Control chart is provided for reference only. The shape of the curve can look different due to the variability in ambient temperature, system set-up, air flow, and other unpredictable factors.
-
Reduced noise without increase in temperature
-
Extended fan life due to the reduced number of fan rotations
-
Optimized heat dissipation at all times
-
Unsurpassed silent performance in Fanless Mode
Fluid Dynamic Fan Bearing
High performance Fluid Dynamic Bearing (FDB) fans are designed to take advantage of the impact absorbance effects of oil. They are extremely reliable and generate considerably less operating noise and heat than ball bearing fans. The lubrication of the bearing surface reduces friction and vibration and therefore lowers overall power consumption. Due to the effortless, quieter rotations and its robust construction, this reliable fan technology also greatly increases the lifespan of the fan.
- When the fan shaft rotates, high pressure oil drifts along the grooves of the bearing sleeve to generate a thin layer of lubrication between the bearing faces.
- As the speed increases, so does dynamic oil pressure and the shaft is lifted from the bearing to create smooth, effortless rotations. The herringbone shape of the groves helps to efficiently channel the lubricant and avert leakage.

Recommended 12V-2×6 Cable Installation
- BOTH 12V-2×6 connectors of your 12V-2x6 cable must always be plugged into your power supply, ensuring they are FULLY INSERTED, CLICK-LOCKED, and TIGHT.
- DO NOT bend or apply force to the cable after it is plugged into place.
