RX 480 Nitro + on a 450W PSU?

[Walter H.W.]

Hello guys, 

 

I thought about getting myself a Sapphire RX 480 Nitro+ for Christmas but I'm not really sure my PSU can handle it.

 

My PSU is a Cooler Master G450M, which is fine for my R7 265 & FX6300 clocked at 4.2Ghz+ CPU. In theory RX 480's TDP is 150W just like the R7 265, but in reality the RX 480 version I'd like to get is overclocked and probably needs more power. I even need an 8-pin power connector which I believe I don't currently have on my PSU and I know using adapters isn't the best thing. 

 

So my question is: is there any chance the Sapphire RX 480 Nitro+ can run without problems with my setup or should I forget this idea?

I don't really want to change my PSU, I "like" it and I don't want to waste money and time finding a new one and selling this.

Thanks to whoever can help!

It will be fine.

Hmm have you checked how much wattage that GPU uses?

By the way, I think my PSU has 6+2-pins, is that equal to 1 8-pin connector (dumb question, I know, just making sure)?

I also found this, RX480 Nitro+ on the left, R7 265 on the right:  

And this from the PSU website:


So theoretically I can run it on that +12V 34A line or am I totally off?

It's enough

You will be fine, no worries

Yup, unless the cpu eats 200+ watts which isn't the case so it's fine.

I know you are worried and that's a good thing, but you don't have to.

The psu is a good one, the rx 480 doesn't need that much power and even an overclocked 6300 doesn't need a huge amount of power.

Thanks for reassuring me

 

The thing is I also have two HDD, 1 SSD and 6x120mm fans connected, plus USB stuff. I thought I was close to the limit already and the Nitro+ could even be up to 60W more needy.

 

In case I get it, I do a full load test and there isn't enough power, what happens then? Do I only loose my PSU (which sucks but bearable) or do I risk breaking the GPU as well?

Well it's a decent PSU so what would happen is the over-current protection would kick in. Or over-drawn, can't remember which one exactly. Let's stick with a safety feature just to keep it simple.

 

What this means is the PSU instantly shuts off to avoid damage. But there is no permanent damage.

It's like pulling the plug out of the PSU. 

 

If this does happen you will need to pull the plug from the PSU, wait a few minutes, plug it back in and it should work again.

Once the safety feature is activated it will only turn off again when the PSU is unplugged for a while.

 

It's possible you will hear a click when it shuts off, to keep it simple that's the emergency switch being turned on.

500 watt would be ideal but this will be fine for now just remember that psu degrade over time

As long as you don't get stupid with crazy OC's you'll be fine and dandy

Yeah well, it's 4.3Ghz right now from 3.5Ghz stock so it's not few.

Anyway, thanks everybody for the help. I guess I'll give it a try!

You'll be fine with OC
