The new ATX power supply is a monster
The ATX Power Supply is a beast of a power supply.
It’s got a monstrously high output, which is a big plus for a budget motherboard, but it’s also not an ideal power supply for high-end PC builds.
That’s because the power supply can’t pump enough current through its power connectors to be useful for high overclocks, and the high-power mode tends to overheat the CPU.
And while you might be able to get away with running your CPU at 1.5V, that’s not ideal for high GPU overclocking, which requires more than 1.7V for every 100MHz of boost clock.
With that in mind, Asus decided to create a new power supply that could pump the most power to the GPU through the motherboard’s power connectors.
The company claims that the new AT-P3x-X8-3D-A1-3 will be able deliver 1.3V+3.3VA/100-pin and 3.3W/400-pin power to an Intel Core i5-4460 2.5GHz processor and a Radeon HD 7970 2GB GDDR5 memory card, with an 80Plus Gold certification rating.
That should mean overclocking a quad-core Core i7-4770K at 3.6GHz is no problem at all.
The only thing missing is a USB 3.0 port.
That could be added later, but that’s unlikely to be the case in a real world application.
Asus says the new power supplies have been tested by a “large number of users,” but we haven’t tested that yet.
We do know that the AT-X power supplies were designed with a “multi-GPU architecture” in mind: two separate graphics cards on the motherboard and a GPU.
We have a feeling that that’s going to be a big part of the new motherboard design.
