RX480 overclocking PSU concerns

[Tweakforce_LG]

Hi everyone,

Last December i built my new build to replace a core 2 duo / HD 5670 PC. 

I got the Sapphire Nitro RX480 8GB card and was worried about overclocking. I bumped it by 25mhz without messing with power limit at all. I heard that even small overclocks increase the power draw by a lot. I have a Seasonic M12ii Evo 520w power supply and am concerned about bumping the power limit up to 50%. Is this safe, and is there a good way to measure power draw so i know its not straining my PSU. Any advice on the overclock itself is also welcome.

Thanks

stick all your hardware into a pcpartpicker list

It'll give you a pretty good idea of what your PC is drawing at max load with no OC

Here is power consumption on load for RX 480 8GB

Spoiler

The PSU is really good quality and should have no problem with it even if the rest component are power hungry which they aren't

Completely safe with your PSU. Max out the power limit.

I already know its fine with no OC as i researched that when buying. Im worried about the possibility of major extra power draw after OC. I have heard that unusual behavior happens, especially with Mem OC

I would only worry about OCing the memory if you had a 4gb 480 since those come with 1750 MHz memory. 8 GB cards come with 2000 MHz and there isn't much more performance to be had from OCing the memory after that. Focus on the core

i have the 8gb so ill leave Mem alone. PC part picker says 320W usage, so ill do some OC and monitor my GPU-Z estimated power draw for the gpu, ill post back if the results concern me. Thanks

Could max OC a 480 on a solid 300 watt PSU with a Celeron 7000 series.

Why a celeron tho lmao,

i hear a bottleneck.

But thanks, that sounds good, i was worried because AMD cards cause global warming with their power consumption  .

Kaby Lake Celeron is 2 cores with HT.. no bottleneck.

Should i use wattman, afterburner or Sapphire trixx?

It's really not that bad. It's cards like the R9 290x and 390x which people are concerned about and will use about double what your RX 480 will.

I like to use Sapphire Trixxx but Afterburner is also quite good.

Afterburner

Afterburner

GPU Z jumps between 180W and 200W with furmark at 1380Mhz with a +50% power limit. Is this normal behavior or is gpuz not accurate at all?

Don't use FurMark. It's useless in guaging real word performance and damages your hardware. If you had a 1st batch Power Color Red Devil 480, you would have destroyed your card. The GPU-Z reading is accurate though.

How would it destroy it?? Also is 230W peak GPU power draw ok at 1395Mhz Core. Thats allot more than the typical 180-200W draw. Is that still well enough below my psu

1st batch Red Devil 480 had low quality VRMs which would immediately die if you ran FurMark on them even though they were fine for every day use and even overclocking. FurMark in general is not a good guage of real world performance. You are never going to get a consumer product that puts that amount of stress on a graphics card.

will running it for 1hr have done anything bad. it seems fine now. you got me worried that i shortened its life

Just don't use FurMark. Use unigine heaven to test your OC stability.

i am now but i ran furmark for closer to an hour and im worried now

Don't worry about it, but just don't use it again. The Nitro 480 has good VRMs so it doesn't matter. The main point is, whatever power draw you're getting with FurMark, you won't use 75% of that with the most demanding games.

Do i need to use caps to tell you to stop using Furmark? It put unrealistic load for your card.

No lol, I uninstalled it as soon as he said it could damage it. I was just worried what it could have already done in my past useage. Also I'm annoyed I only hit 1395mhz not 1410mhz core. Heaven benchmark crashes if any higher than 1395mhz

With extra voltage or stock volt?
