Finally, both NVIDIA RTX 4090s can be powered
Power demand is rising again, as are kilowatt-class PSUs such as the Thermaltake Toughpower GF3 1650 W. A single ATX 3.0 12 V rail can deliver a full 1650 W at 137.5 A to the components and comes with 12 pairs. +4 pin PCIe 12VHPWR connector. At a suggested retail price of $330, it’s also one of the most affordable ATX 3.0 and PCIe 5.0 capable PSUs, though it’s still expensive.
TechPowerUp’s testing showed that the power delivery of this unit was amazing, handling loads up to 2000W while maintaining 43°C and not shutting down with a transient load of 3200W. That’s a good thing, and while the 10-year warranty should provide some relief, it also suggests that the overpower protection could be set a little higher for longer life.
Another drawback was that the fan put out over 50 dBA at full load to maintain such a comfortable temperature. On the other hand, if you need that much power, the Thermaltake Toughpower GF3 1650W PSU is your best bet.
