Determining what power supply do I need

Aleksa21 · Jun 29, 2014

Hello,
I am about to buy a new gpu and cpu. But I am not sure if my current power supply can handle the new gpu and cpu. The gpu I am about to buy is AMD Radeon R9 280X Sapphire Dual-X and the cpu is AMD FX-8320. So my question here can u tell me with what wattage power supply I need.
If u need further information just ask !

for such setup a 550w one would be fine. if you would aim for overclocking both cpu-gpu a 650w would be a perfect fit, providing the extra headroom. what is the rest of your setup?

Here's a calculator. Don't forget to enter your mouse & keyboard in USB devices if they are such.

If you need something specific just ask!

what is your current psu exactly? is that your mobo http://www.msi.com/support/mb/860GMP43_FX.html#support-cpu if it is, it cant properly run FX8320 , it is limited to 95w tdp cpu. you will also need an mobo upgrade!

No my mobo is 760gm-p23 (fx) .
And the power supply is CHIEFTEC CTG-500 - 80P also now I see that it is 500 W powre supply

ok but the same applies to 760gm-p23 (fx) cannot run 125w tdp cpu like 8320. i wouldn run any fx cpu, or try to overclock! you need at least an amd970 chipset mobo. as for your psu, running a gpu like 280x isnt recommended. i would only run an R9 270 with such unit.

The motherboard and power supply are both insufficient.

Thank you so much for the help !!!
This is my last question can you tell a name of a cheap moba that can run the cpu and gpu I selected and a power supply that can mange all of this (what wattage is enough for the set up ).
And again I really appreciate all of this help.

the specific mobo is very good and can even o/c the fx. be carfull though cause picking a non990fx mobo for fx cpu can be very tricky.! another good option would be asus M5A97 EVO/PRO shouldnt go any cheaper for such cpu!the psu is plenty and great quality

Can you check if this MSI 970A-G43 can fit te roll because in my country the retail price is lower than 70$
P.S. The owners of the shope are telling me yes but I want to be sure

MSI 970A-G43 < Thermal nightmare.

Aleksa21 · Jun 30, 2014

Do you mean it is a bad moba or something else ?

Dark Lord of Tech · Jun 30, 2014

Yes very poor power and thermal design = HEAT

Aleksa21 · Jun 30, 2014

How about Gigabyte GA-970A-DS3P it is also a cheap mobo and I think the shop owners said that is compatible with the set up I want

chris987 · Jun 30, 2014

990fx is designed for the FX cpu and only few of the older chipsets are actually able to handle them especially FX 8320 - 8350 we cant recommend you something that will lead on trouble! the DS3P doesnt have the appropriate thermal design or VRM heatshink see for yourself gigabyte power phase
