Seasonic VERTEX PX PLATINUM 1200W ATX 3.1, PCIe 5.1, modular

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.
