Besides the upgraded TX-1600 model, Seasonic also released a new PX-1600 unit which meets the strict ATX v3.0 requirements, meaning that it can deliver up to 3200W for short periods to cope with the increased energy demands of the current and upcoming GPU generations.
I have already reviewed the TX-1600 ATX 3.0 model, and the time has come to look at the PX-1600 ATX 3.0 (PX-1600 from now on). There are few options in the mega-Watt category since delivering the PSU’s double power is challenging even for 0.1ms if its max power exceeds 1.5 kW. Besides Seasonic’s models, the only other ATX v3.0 ready PSU with over 1.5 kW capacity is the Thermaltake ToughPower GF3 1650, which requires ear plugs to use it under load.
With a 210mm length, this is a large PSU, but a 1600W PSU will be used to power lots of parts, which won’t find in a small or even medium-sized chassis. It would be wise to check whether your chassis can accommodate a 210mm PSU before you buy the PX-1600.
Like the TX-1600, the PX-1600 comes with two 12VHPWR connectors, set to 600W each, allowing it to handle powerful workstations, equipped with a pair of RTX 4090s.
