Thermaltake Toughpower GF3 1650W For Your Extreme 12VHPWR Needs
Finally You Can Power Both Your NVIDIA RTX 4090s
Power demand is on the rise again, as are kilowatt class PSUs such as the Thermaltake Toughpower GF3 1650 W. It’s single ATX 3.0 12 V rail is capable of delivering the entire 1650W at 137.5A to your components and it comes with a pair of 12+4 pin PCIe 12VHPWR connectors. At an MSRP of $330 it is also one of the more affordable ATX 3.0 and PCIe 5.0 ready PSUs, even if that is still a hefty price.
TechPowerUp’s testing showed this unit has amazing power delivery, it handled loads of up to 2000W while still remaining at 43 °C, and it didn’t shut down with a 3200 W transient load. While that is good, it also suggests the overpower protection might be set a bit high for a long lifespan, though the 10 year warranty should reassure you somewhat.
The other downside was that in order to maintain such comfortable temperatures, the fan produced over 50 dBA at full load. On the other hand, if you need that much power, then the Thermaltake Toughpower GF3 1650W PSU is certainly up to the task.
The Thermaltake Toughpower GF3 1650 W is the only PSU on the market that offers two 12VHPWR connectors, each capable of 600 W. This unit can support two NVIDIA RTX 4090s with their power limits set to max, along with a powerful CPU and other power-hungry components.
