Can I use a Radeon RX 580 graphics card with 430 Watt PSU

[mulayim_sert]

Hello all,
I have a Ryzen 5 2400G APU and a 430 Watt Seasonic ECO 430 PSU. I want to add a Radeon RX 580 into my computer. Is it possible with this PSU. PSU has 396 watt power in +12V and since I won't use the integrated graphics card and Radeon RX uses around 320 watt and my CPU probably will use 60 watt then my PSU should handle the load am I right?

Depends on the rest of your build.

Use PCPartPicker or any online PC Watt Calculator like from bequiet, coolermaster or any other PSU brand. It will show you how much wattage your build uses. Usually, it's recommended to go 50W over (at least).

Thanks, calculator from the Seasonic website tells me that the load will be 362 watt and (as you said) it recommends me a 412 watt PSU. So, my PSU will be okay right?

I personally dont think a 430w seasonic is enough.

The general concensus is with a rx 580 you want 450w 12v minimum.

These cards can touch 240w peak at times.

I usually add another 50-100 to whatever they recommend.

It's like a water pump. If you need a pump that pushes 40L of water per minute and buy 40L pump. It will also be at 100% capacity and will get worn out quicker. So you buy a 60L one.

If yours uses 362, and they recommend 412. I would go at the very least for a 450w and even better a 500w.

What's your budget and where do you live? I can help you pick one.

Thanks again for the answer.

You are right. I also want to overclok both the CPU and GPU so actually I should go even higher. The problem is that I have just assembled this PC and boughth the PSU so I don't want to buy a new one. I wanted to play Hellblade Sensua's sacrifice and a bit disappointed to see that my Vega 11 is not sufficient for this game.

I spent significant portion of my budget to the rams: 2x8 Gskill FlareX 3200 which is very expensive. It is not bad of course but I could have bought an ordinary 8 gb ram and save the rest to buy a better PSU and a second hand Radeon RX 580. It will fit perfectly.

I am just writing this so maybe become helpful to someone else. All this news about ram compatibility issues frightened me a bit.

You could run a gtx 1060 on that psu safely , its on par with the rx580 if you can find one at the right price.

Another issue is that I have chosen my monitor to have Free Synch to work in accordance with my Vega 11, so I don't want to switch to Nvidia.

Cpu with OC : anywhere upto @100w
Rest of the pc: anywhere upto @100w
Rx580 (depending on model) : anywhere upto @240w stock + boost).

Overclocked you well exceed that psu ability, even stock you reach @400w max, with a constant gaming load of @300-320w. That's a lot on that psu. Another budget psu such as the Seasonic S12-II/M12-II 520w would be a far better option as a minimum, a decent 550w would be recommended as there really aren't any decent 500w units.

What about Radeon RX 480. I can use it right and it provides significant performance update compared to my Vega 11?

Roughly the same draw as a Rx580, pretty much a 580 is a tweaked 480. Honestly, it's not an easy choice. The gtx1060 has comparable performance, often slightly better and works just fine on a 430w psu, that's the actual recommended psu for that gpu, but invariably currently it costs a little more. On the other hand, a new psu and Rx580 will be roughly the same price for similar performance. Granted that's US prices, depending on availability and location, that can change.

Unless this is a somewhat priority, Thanksgiving isn't far off and some of those sales are unreal, if you can take advantage of them.

Yeah, I will wait and buy around thanksgiving then. I have also learned that Free Synch doesn't work with the HDMI port . All those time I was thinking that I was getting the advantage of it. Another mistake!

I would suggest not overclocking for the moment with this PSU.

You mean if I buy a graphics card right?

I assumed you meant once you bought the RX580. What GPU do u have right now?
