[Poll] [Eve Core] [eGPU] How many Watts would you need for a GPU?

Development What's Next?
1

So, here comes one of the first polls for the potential accessory :slight_smile:

How many watts would your GPU need from Eve Core?
I’ll ask in terms of PCIe connector as this should be easier for many people :slight_smile:
And no more than 2x8-Pin since we’ve barely seen more than that in the last generation of GPUs and since the latest one should have greatly reduced power-draw that should suffice for most versions of GPUs.

  • 75W (No connector on the card)
  • 150W (1x6 Pin connector)
  • 225W (2x6 Pin connector/1x 8 Pin Connector)
  • 300W (1x6 Pin + 1x8 Pin Connector)
  • 375W (2x8 Pin Connector)

Thanks for voting!

EDIT:
Here are some listings for various GPUs with how many connectors they at most have:
GTX 1080: 1x 6 Pin + 1x8 Pin
GTX 980Ti: 2x 8 Pin
GTX 970: 1x 6 Pin + 1x 8 Pin
GTX 960: 1x 6 Pin / 1x 8 Pin
GTX 750 Ti: 1x 6 Pin

R9 Fury: 2x 8 Pin
R9 390X: 1x 6 Pin + 1x 8 Pin
R9 380X: 2x 6 Pin
R9 370: 1x 6 Pin
Rumor: RX 480: 2x 6 Pin?

COUPLE OF WORDS FROM @Konstantinos:

Guys, its legit! We are going to China next week and we will look into various eGPU dock possibilities there. So more polls to come soon :smiley:

I read somewhere that RX 480 will need 150W. Don’t know about the pins though.
Thanks for the poll :grinning:

Found this:
Load Wattage: 134 W Recommended PSU Wattage: 184 W

And this:

You’ll notice in the above shot that AMD’s Radeon RX 480 sips power from a single 6-pin PCI Express connector.

@AntonyTerence @Artur Yes,but the aftermarket-cooled devices usually have one power connector more for better overclocking :wink:

I voted for 300W for exactly that reason :grinning:
And if something more powerful comes out.

You’re focusing on too high-end cards here. Nobody needs a gtx1080 with such a CPU we have here. I’d rather focus on 950, 960, well MAYBE even 970, even though that’s already a stretch. I don’t know if 1050 or 1060 has been released yet. Other than that, some older gen cards such as 740 should go here.

@AntonyTerence, who told you new cards will be power hungry? Performance per watt will only increase, because otherwise there would be no point in buying newer cards.

It makes little sense to artificially limit the cards you can put in here. There’s no telling if someone will buy a card that will be shared between a beefy desktop or higher end laptop AND PF. Or if someone replaces their last card and decides to put the old one, easily with greater power draw than whatever is arbitrarily targetted, in the dock. Considering the cost, no need to skimp on the power supply. Someone might look at it the same way we look at all these 2in1s now, going “well why did they do that? Clearly it would have been better if…!”

Besides, we also need enough overhead for the eGPU dock to provide power for charging.

Yes, which is why I personally would suggest putting in a 500W PSU - we should have a bit headroom and then also provide 300W to the PSU - and 100W to the device that is hooked up to the eGPU due to USB-PD standards.

I second the 500-550W PSU choice. Three reasons that I am going by in my choice: 1) We are not limiting anyone to the cards they would like to use in their Core, be that a new card or a power hungry card they are salvaging from the old desktop. 2) With power headroom, cards can be overclocked if desired, or factory overclocked ones can be used 3) A higher power PSU will spend much less time @ max loads, which more than likely will lead to a higher reliability

So do you think there’s a need to make another poll with a higher limit? @Ivan_Lazarenko @iKirin @RVelocity

No, because we know how much people want for the GPU, now we can add 100W for the PF itself and some headroom and we’re finished :slight_smile:

My point is not about limiting EVERYONE to 200W. It’s about giving people a choice. I’m saying that not all people will need more power. I would suspect about a half. So what I’m suggesting is to have two models with different power PSUs. Because I and other people like me don’t want to pay for something I will never use. I would prefer it as cheap as possible. Even a $10 difference means a lot here, if we’re aiming for under $100.

Paul, people with HQ mobile processors could use the Eve Core too. So supporting higher W is better Imo.
And about future cards needing more power, I was just wondering if the GTX1080 Ti would consume more than a GTX1080. I do agree that cards are consuming less power than their predecessors.

HQ laptops already include GPUs, as I already said above. Often 980M, or even some desktop GPUs.

Those who will want to use or re-use a higher powered card will need quite a bit of power running to them. Here is the link to the testing of R9 390X and GTX 980 http://www.hardocp.com/article/2015/07/06/msi_radeon_r9_390x_gaming_8g_overclocking_review/6#.V1sU1pErKCg
GTX 980 at load needs more than 300W
R9 390X at full load will pull 494W

A 200W PSU will not even be able to supply those cards + PF charging at idle :cry:

Two models would work. Or sacrificing form factor and using a standard PSU type, and just selling a bare dock with the appropriate connectors which you can slot a psu and gpu into. As long as we have good quality and choice.

I think that having a default sized ATX-PSU and being able to retrofit it how you want would be great :slight_smile:

I agree on the ATX size PSU completely. They are cheap, powerful, reliable and can be easily swapped with another one if needed.

I think anywhere between 300W and 500W is good. People do use 500W and 300W PSUs to power their systems, with a lot of components including the GPU, so considering the dock will only power a GPU (rather than a whole PC) 300W to 500W should be more than sufficient. I think, anyway. My PC (luckily!) has a very large PSU, so I haven’t got the experience to say for certain. I just know people do build PCs with said wattage PSUs from the PCMR sub on reddit.

Edit: https://seasonic.com/ that company makes very reliable, high quality PSUs. Not sure about pricing though.
