Can a 750W PSU support a system with fx-9590 and r9 290x?

Hello everybody,

I'm thinking of buying the following power supply unit: Antec High Current Gamer 750W Modular Active PFC 13.5cm psu HCG-750m.

My question is can it support a system running on a fx-9590 cpu and a r9 290x gpu? Assuming the system is busily handling a modern game on high specs, is 750w enough?

Thanks

A quality 600watt power supply is more than enough for a high-end, single card system. That Antec may be considered over-kill.

Thank you for answering.

I forgot to mention I wish to purchase 1 HDD of 2 tb and 2 SSD each of 240 gb. Does it have any impact on the wattage?

I also think I should have anywhere from 2-4 fans I suppose. What impact would this have on the wattage?

Would 600w be enough for all that?

Easily. The only reason you'd need to go above 600watts is if you elected to install a second graphics card for CrossfireX.

If you're planning to overclock the FX-9590 into the 5 GHz range you better be looking for an 850 Watt PSU.

The CPU itself will be drawing over 310 Watts through the 8-pin CPU power connector when the FX-9590 is OC'ed to 5 GHz and running at full load.

A 750W is the bare minimum if no overclocking is being planned.

Thank you both for answering. From what I gather from you, either 600w or 750w can be considered a bare minimum, then.

And no, I am not planning to overclock. No idea how to do it even xD

I consider a 750W PSU to be the absolute bare minimum when using an AMD FX-9590 with a Radeon R9 290X.

Stick with your original choice of the Antec HCG-750M since it should have a sufficient maximum combined +12 Volt continuous current rating to handle that CPU & GPU combination.

Thank you very much. It is very helpful to make this type of inquiry before a purchase.
