am having a bit of a dilemma here
am building my second mining rig currently having just 2x 3080s

one got dual 8 pin and the other card needs 3x 8 pin !

am having tough time where i live sourcing here in turkey a PSU with sufficient VGA Cables !! (ya ironically)

the best i could find is this and SEEMINGLY it got only 4x VGA Cables (8pin)

i understand a 3080 draws 220w IF successfully downclocked, so does that mean using a 6pin splitter to dual 8pin splitter not an option ?

sadly i failed to find any GOOD 8 pin to dual 8 pin splitters here in turkey !...

any help appreciated i need this rig up and running ASAP !...

thanks,

pcie splliter safe run under 200w and dont use as double, there is cable mod provider in local store you might buy custom pcie cable, or check pcie port & buy on e-commerce, standar psu should easy to find, and consider cheap compared buying custom cable

If you need to quickly connect 2 video cards and you need 5 connectors 4 x6 + 2pin PCI-E.
The power supply has 8 connectors for connection, but the specifications indicate 4 x6 + 2pin PCI-E and 2 x (4 + 4) 8pin CPU.
If I understand correctly, then 2 connectors are still free. You need another 6 + 2pin PCI-E cable.
Perhaps it is universal, and it can be used from other broken power supplies. Such cables cost 7-10 dollars.

>> If I understand correctly, then 2 connectors are still free. You need another 6 + 2pin PCI-E cable.
trust me i got few cables lying around, just not sure how to know if it is universal or not !...

Just do a store check if possible and check the voltage with a multimeter.
Or ask a question to technical support.
I'm used to using a Corsair or Cougar, so I already have a lot of different additional cables due to the breakdown of several power supplies.

boys do you think this will do for my situation Huh

8 x 8/6-Pin PCIE connector
With such a power supply, you can install a third RTX 3080 video card.

I've never heard of the brand but it solves your connector problem.

2 3080s with a 1000W PSU is close to the limit. If you can't get good quality cables it makes a big difference.
That includes the cables that connect directly to the PSU.

Don't consider splitting unless you have an 8 wire cable with 8 pins connected to the PSU. Many PSUs come with
a mix of cables with either 1x8 or 2x8 GPU connectors. You can convert a 1x8 to 2x8 with a good splitter.

Also depending on cable quality you can convert a Molex cable to 8 pin PCIe, preferably use a 2xMolex to 8 pin converter
and 2 seperate Molex cables to better distribute the load.

Whatever you do watch for signs of overheating of the cables or connectors.

ur mostly right 1000w is about the limit for 2x 3080s at 80% limit coz its a server board with 2x CPUs, RAM, SSD etc...

no way around it bro i cant source a good PSU here with plenty of cables, unless i go with the HP https://www.amazon.com.tr/DPS-1200FB-438202-002-440785-001-Ethereum-MADENC%C4%B0C%C4%B0/dp/B09378QX91/ref=sr_1_3?__mk_tr_TR=%C3%85M%C3%85%C5%BD%C3%95%C3%91&keywords=hp+psu&qid=1637615686&sr=8-3
the only one i had in my original post, but u said:
>> Don't consider splitting unless you have an 8 wire cable with 8 pins connected to the PSU. Many PSUs come with

i found out that 1000w PSU got 4x 8 pin connections, so i was planning to do it like this:
2x 8 pin VGA Cables/Connectors will go for 1st 3080 (this one needs only 2x 8pin)
1x 8 pin VGA Cable/Connector will go to 2nd 3080 (this one needs 3x 8pin sadly)
Now we r left with 2x 8pin ports unfulfilled on the 2nd 3080...

Will use One 6pin to dual 8pin splitter to convert last vga connector/cable for the 2nd 3080

good idea ?

sadlyill use all the molex cables to power the risers Sad

seriously that second 3080 with 3x 8pin is giving me trouble and the lack of good PSUs in this country !...

thanks,

using server psu is doable & cheap, but to loud for mining in home, my advice is using evga platinum series if you want get lot of pcie cable

or using pcie splitter, and yeah you can buy pcie cable from aliexpress,

the cheapest and best psu for bucks is antec hcp series, trully outstanding and long lasting psu

With aliexpress, delivery is now very long, because there are a lot of orders at the end of the year and there are long queues at customs.
It is better to look for devices in your city and in the communities of miners. Look for such communities in telegram or other messengers.

okay let me look for a good one.

https://www.newegg.com/corsair-hx-series-hx1200-cp-9020140-na-1200w/p/N82E16817139205?

check if newegg will ship the one above.

it has four pcie two headed cables.

use two two headed to the two jack 3080

use two two headed to the three jack 3080

if you set the cards to 240 watts the cables will not overload.

now i have zero idea if newegg would ship 🚢 to you.

but that psu will do the job.

if newegg does not ship to you let me figure out if There is a way to get it to you.

My DPS 1200 FB A psu units were always pretty quiet,
the noise stabilized to a low level some time after the start-up.

I've used them for a gpu rig and for few Avalon 7 series miners.

edit: This is how my GPU rig used to look like https://bitcointalksearch.org/topic/sold-4x-gtx1080ti-gpu-rig-installed-in-a-inter-tech-server-computer-case-3268965

Your question is about an altcoin gpu miner and this is btc mining hardware area. I asked mods to move it.

But what comes to your question,
a good sturdy psu would be:

1x HP DPS 1200 FB A (max. 1200 W at 230V, or 900 W at 110V) server psu
1x HP common slot psu breakout board for 12x 6-pin
12x good quality (6+2) -pin pcie power cables
1x pico psu for motherboard powers

This setup was roughly what I used for my previous gpu miner I had back in the days.

Is this the only setup possible؟ I heard those hp psu are really loud …!
