IS PSU 500W ENOUGH FOR AMD r9 280x ?

imokgoca · Mar 27, 2014

Hello,

Just wondering if 500w PSU will be enough for r9 280x ? Thanks.

System specs:

AMD fx6350
8gb ddr 3
PSU: Silverstone Strider Plus ST50F-P 500 W

it should work but theres a risk as the psu will b around full load

I wouldn't run a 280x on a fx cpu. Is that cpu overclocked?

You are safer off just getting a new 650W PSU. (that's what I did..520W to 650W for 280x)

Not all PSU's are created equal so what matters is the quality of the unit, so knowing the brand and model is important for correct answer. The Silverstone is a good unit and should handle it.

That PSU will not run your system with an R9 280x installed at full load. It simply can't supply enough amperage on the 12 volt rail.

I would recommend this unit: http://www.newegg.com/Product/Product.aspx?Item=N82E16817151096

The specs I found for that Silverstone unit list it with a 34 amp 12 volt rail.

The R9 280X should have a max TDP of 250 watts and the FX 6350 should have a 125 watt max TDP. That is a 31.25 amp load, even before we consider the rest of the system.

rolli59 · Mar 27, 2014

PSU has 34amps or 408watts available on the +12 volt rail, total system load measured under 400watts http://www.anandtech.com/show/7400/the-radeon-r9-280x-review-feat-asus-xfx/20 so it should work.

That particular Silverstone unit is made by FSP and is considered a budget PSU, not an excellent PSU.

I went with an XFX 650W for my 280X. In the UK it's only £5 more expensive than the Silverstone 500W you linked and it supplies 53A, which is plenty. Great PSU, haven't had a problem with it.

You have no idea what you're talking about, that CPU even at stock clockspeed is plenty enough to run any games
maxed out except crysis 3 and metro LL and in those game he will not maxout because of the GPU not the CPU...
The 6 core FX will feed an r9 280x @ 100% in any games.

It is not a gold rated top quality but still good http://www.hardwaresecrets.com/article/SilverStone-Strider-Plus-500-W-Power-Supply-Review/1369
I am going on the assumption that the OP already has it and is asking if it will run the card which it will, if he does not have it already then I would get a different unit.

bigpinkdragon286 · Mar 27, 2014

XFX is a good brand of PSU, manufactured by Seasonic.

Its not overclocked

I already have it yes

it's okay as i said in my comment even at stock speed that CPU is well paired with a r9 280x it will not bottleneck the card in any way

imokgoca · Mar 27, 2014

50% comments yes, 50% comments no

Unfortunately i already have silverstone.

imokgoca · Mar 27, 2014

bigpinkdragon286 :

Mine is silverstone, not XFX

Darkpagey · Mar 27, 2014

Well then, the Silverstone is a good PSU but for the 280X it is in my opinion underpowered. Under load it's going to really struggle because the 280X is a power hungry card.

envy14tpe · Mar 27, 2014

Go ahead and run your 280x on that PSU...but if something happens then hate to say.....

paitjsu sadff · Mar 27, 2014

i'd suggest you use this tool : http://extreme.outervision.com/PSUEngine
enter everything that is in your PC that runs off that 500w PSU you have and hit calculate, i did it with standard stuff ( 1 hdd, 1ssd, 1dvd-r, 1 120mm fan, your CPU and a r9 280x) and the results is recommanded 484watts...so you'll be pretty close, i would order a new bronze certified 600w PSU if i where you...

imokgoca · Mar 27, 2014

Ok guys, thanks for all the answers, i guess the risk i can take or not is on me.

imokgoca · Mar 27, 2014

paitjsu sadff :

i get 504 W

paitjsu sadff · Mar 27, 2014

imokgoca :

there you go...so unless you would have a gold certified 500w PSU i wouldnt run that system of that powersupply for a prolonged time period...

Thanks for answering. i guess ill consider getting corsair cx600.

paitjsu sadff · Mar 27, 2014

imokgoca :

that would be a great idea, a good powersuply is a good invesstement and what money you put into it's quality you will most likely get back over time in energy savings...good quality PSU will need less powerdraw from the wall to convert into real usable power for your computer...they also last longer and provide more stable current for your PC, protecting the components from failing due to overvolting or undervolting...Corsair CX series are good PSU for the price...one thing to think about is that if you might go crossfire or SLI in the future you might want a 750w unit from the bat that way you have power to run 2 cards...its up to you, but 600 will be fine for your current system.
