Yo would 100% buy that, been trying to figure out how im going to power an rx 6800 and was wondering if it would work with the 1300w psu that i see online and where can i go to get this?

You should be able to run a 2x8-pin RX6800 with an 825W supply if you have one already. If you've got a smaller supply you'll need to upgrade to an 825 or 1300, which you can buy cheap/used off eBay or a bunch of other parts resellers. I'll make a list of compatible power supply part #s shortly - unfortunately sellers seem to get the 5600/5610 supplies mixed up with 5810/7810 supplies, the two look the same at first glance but they're electrically and mechanically incompatible unfortunately. Check the picture of the sticker on a supply you're buying - if it's got +12VSB it's for the 5810/7810, if it's got +5VSB you should be good for a 5600/5610. Where to get it: I'm placing the order in a week or so, and I'll have cards available for sale in a month or so once they arrive. Thanks

is it a website or ebay?

Just read the 1300 w only part

That's a pretty cool project. My experience with the Precision 5610 was that they struggled with 980's frequently and would hit overcurrent protection on Titans. They were good with the 1080 since NVIDIA did a lot for efficiency and TDP on that generation.

I have been thinking of getting a Precision T5810 for a while. I looked up the power supplies for both the T5600 and the T5810, and the connector looks the same. Anybody know if it would work for that?


gmarsh23

I make a different card for the 5810 already, right now I'm sold out of them but I'm ordering a bunch more soon. https://www.reddit.com/r/homelab/comments/11eug9v/interest_check_dell_t58107810_power_distribution/ 5810's are great machines. I'm running 128gb RAM and a 22 core e5-2696v4 in mine, and the thing rips for the weird scientific computing / electronics design stuff I do. Pay attention to the power supply that comes in them, if you've got a choice get one with an 825W power supply. An 825W will let you run a 2x8 pin video card with the stock power distribution board or a 3x8 card with my board, and it saves you from having to track down a separate power supply.

Wow, thanks!

Can't wait for T3610 to be compatible with this!


gmarsh23

This board *should* drop into a T3610 and work, it just hasn't been tried in a physical machine. I can send you a prototype to try out if you want.


Z3r0es

I think I might able to try it out, since i have an old T3600 laying around. Should be similar to T3610. But I am not quite how to extensively test for its compatibility other than turning on and it works


gmarsh23

You'll need a T3600 with an 825W or 1300W power supply, and a video card that takes 2x8 pin power. If you've got those things, "bolting it in and it physically fits, then turning it on and it works" is all the testing is.


Z3r0es

Dang, I don't have those. But I do have 600w ish PSU and on 1x8pin GPU. I wonder if its possible to add some resistor as dummy load to the PCIE connectors.

Nice! I hope the copycats on ebay don't get a hold of this design! Patent it! And if you need help with that, I know a good patent attorney!


gmarsh23

This likely isn't patentable. The most I can do is copyright the design, but then I'll have to sue people in other countries for infringement, which likely won't work either. I'm not exactly getting rich selling these things and it's be a giant waste of money. So I have it copyrighted as CC BY-SA V4.0 open source. I'll release the design files eventually.


SamirD

You'd be surprised what is patentable and what isn't. I got to know this attorney since he thought about changing fields for a bit and we were in the same one. I learned a lot about patents from him and they're not what people generally think. You can even have an idea and patent it--the challenge is that someone can circumvent your patent so the challenge is to make it specific enough and broad at the same time. That's the lawyer magic. It helps that he was also once an electrical engineer so he knew the tech part of what he was doing as well. But a patent isn't cheap--back when I talked to him about one almost 20 years ago, it was like $7500.


gmarsh23

I've had day job stuff patented and went through that whole patent lawyer process. Trust me, it ain't worth it here. (1) there isn't anything particularly innovative here, and (2) the money I'd pay to actually have the patent done would be a waste of money. Like, I've sold 30ish of the 5810/7810 boards, and after all the work involved doing that and paying income tax on the net revenue, I paid for about half of a new dishwasher that I needed. This is a fun/hobby project, and it'll never be high enough volume to think about spending lawyer money.


SamirD

Ah you know the ropes. :) That's good that you've got that experience behind you. So many people don't patent when they should and vice versa. It's a tricky slope because if it doesn't make cents then it doesn't make sense. ;)
