Riser sata cable burned!

Hi everyone,
Today for the second time my rig stop working due to burning of risers sata cable.
I'm still new in mining,
My rig has
Galax Gtx 1060 OC x4
8 GB ram
PSU Corsair hx1200i
Motherboard ASRock H81 PRO BTC R2

I'm using ethos my card are working at 22.5mh/s each, usually they are stable but after few days the sata cable that give power to riser get burned. I'm using only one sata cable with 4 connection at the moment. Should i Just connect only 1/2 GPU to each sata cable?

Thank for your help

If the cable is burned, then it is too much electrical load. You should study the technical characteristics of your cable. In any case, the cable and connection should not get too hot.

you connect 4 risers at 1 cable? Huh, you are just asking for trouble. SATA max load is around 50W, so its just not safe you connect more than one riser per sata cable. Some even recommend to avoid using sata cables entirely.

Are you out of your mind? Thank the gods you are not burned alive yet. Sata cable is for maximum 2 cards and that is too much, preferred is one per card.

Connect 4 GPUs on one cable -> 100% catching fire!

You should connect 1 SATA cable for maximum 2 risers, connecting to only 1 riser is the best. 4 risers on 1 sata, the loading current is too much!

Thank you for your reply! i'm using the Corsair hx1200i but now al my sata cable are burnt can i use other sata cable from other psu?

thanks for your help

What about Molex? How many gtx 1070 should be connect for one cable? May be enough to monitor the temperature of the cable?

SATA is capable of supplying some good amounts of power but it sounds like your cables are too low AWG to actually take the load. I’d try buying some PCIE plug risers and seeing if those work. Molex could also work, but watch out for risers with cheap parts and construction.

I recommend one GPU per SATA cable. Those things are not made for high power use cases at all and PCI express plugs are what you want 99% of the time.

Yep no more that 2 risers per cable. Everyone here has probably learned the hard way...

No matter what type of cable you're using to connect the risers, never use more than two connections per cable. I use PCI-E 6-pin risers and use 8-pin to dual 6+2 pin splitter cables to connect two risers per PCI-E cable. If I have to use a sata or molex cable, I use dual sata/molex to 6-pin adapter cables. That way the load is spread over both connectors.

8-pin PCI-E to Dual 6+2 PCI-E splitter

Dual sata to 6-pin connectors.

If you used 4 powered riser for feeds 1 sata socket, Is it burned? this normally and so dangerously.
2POWER RİSER -> 1SATA this is a normal and safety

Thank for your reply I think I will remember forever.
Now I don't have any sata cable left my question is where can I buy more? Should I buy from Corsair ? My PSU is hx1200i

you put four gpus on the cable you melted the cable.

And you ask if you should put less gpus.

The answer is yes put less gpus 1 or 2 max.

Go to the corsair website they have the exact cable you need

1 or 2 gpus at the most.

yeah, 1 or 2 gpu max per sata cable

I have experienced this. Follow the rule of one card one cable and you will never face this issue again! Wink

I use sata for 2 cards max. Any more and you are asking for trouble

For the AMD 7970 or R9 390, it can supply up to three. But for the modern cards, it can only supply 1 to 2 cards.

also make sure that the cable/psu that your using is true rated and don't overload your cables man
