6-pin PCI-E connectors are rated for 75 W max. Risers will typically use up to 60 W max, so you should be OK running two 6-pin risers from one PSU 8-pin PCI-E cable. I have run up to three 6-pin risers from the PSU cables that have a 8-pin + a 6-pin pigtail. I wouldn't go past three 6-pin risers per PSU cable. If you run out of PCI-E connectors on your PSU, you can use a SATA to 6-pin converter, but I would not run more than one 6-pin riser per SATA cable. I would also rather use a dual SATA to 6-pin adapter to spread the load over two connectors on the same PSU SATA cable. https://www.aliexpress.com/item/PCI-E-Adapter-Cable-Dual-15-Pin-SATA-Power-To-6-Pin-PCI-E-PCI-Express/32840243382.html?

SATA connectors are rated for 54 W max, which is why I don't like using single SATA connectors with risers. As long as you're not dual mining, which pulls a lot more power through the risers, it may be OK to use a single SATA connector to power one riser. Check the connector every so often to make sure it's not getting hot.
Molex 4-pin connectors are a much better option than SATA connectors, but never use more than two risers connected to the same PSU molex cable.

I have 4 molex cables in my psu, so I will connect each to one riser.
What is power difference between sata and molex cables ? How much wattage molex cable can provide

Molex 4-pin connectors are rated up to 132 W each, but the problem is they almost never need to use anywhere near that power. PSU's typically use thinner gauge wire for molex and SATA cables compared to PCI-E cables, which are made to handle a high load. That's why you should never use more than two risers per SATA/Molex PSU cable, or you risk overloading the wire.

Hey guys. I have Fortress 750W PSU Platinum, and I am going to plug gtx 770 , x2 gtx 1050 directly in my motherboard pcie 3.0 , I also want to use 3 risers to connect x3 gtx 1030 . My question, is it possible to power two 6pin risers directly using the 6+2 pin cables that are connected to my PSU? and also power one 6 pin riser with my psu sata cable. My PSU has x4 6+2 pins and x8 sata cables. https://www.amazon.com/Rosewill-FORTRESS-Platinum-Certified-FORTRESS-750/dp/B008G9MX48/And I am planning to buy this riser : https://www.amazon.fr/Jsdoin-alimenté-Adaptateur-dalimentation-Pin-6Pin/dp/B078PZYYBC Thank you very much. ![](https://ip.bitcointalk.org/?u=https%3A%2F%2Fimagescdn.tweaktown.com%2Fcontent%2F5%2F3%2F5335_19_rosewill_fortress_750_watt_80_plus_platinum_power_supply_review.png&t=663&c=Ep5j1MFN9As6kg) So looking at this, you got 2 molex cables while 3x connectors on one of them and 1x connector on the second. ![](https://ip.bitcointalk.org/?u=https%3A%2F%2Fimg.purch.com%2Fgigabyte-geforce-gt-1030%2Fo%2FaHR0cDovL21lZGlhLmJlc3RvZm1pY3JvLmNvbS9RLzcvNjkwNDE1L29yaWdpbmFsLzAwLVdhdHRhZ2UtT3ZlcnZpZXcucG5n&t=663&c=A8BEsHYBUq2vdw) Second picture here of GT1030 that you will put on your risers, maxed out at 33 watts . So i think you are good to go. The only thing that i think might be trouble for you can be the pcie lanes for you on the motherboard.

Thank you guys for advice.
I actually changed my plan. I am thinking about not using risers, so I will just plug in my gtx 770 and two gtx 1050s directly into my motherboard.
My only concern now is that I cannot supply gtx 1050 with power from my psu 6/8 pin connectors. Will my motherboard be able to provide the x2 75W (150W total) via the x16 pcie slots for my two gtx 1050s ?

Do you think x16 pcie slot version 2.0 in my old PC will be able to power 1 gtx 1050? It provides up to 75W, diff between v2 and v3 is just bandwidth. Your fine. My motherboard is an older motherboard (AM3+), and its PCI-E2 and its running 2x Zotac 1050 TI
