Can someone help me please Cry

yes, its fine. I run two 1050TI's straight from my motherboard.

Thank you for confirmation. 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

That's really wonderful. Thanks mate Cheesy

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 ?

what motherboard do you have?

I have MSI g45 z87 motherboard

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.

So looking at this, you got 2 molex cables while 3x connectors on one of them and 1x connector on the second.

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.

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.

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

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.

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.

How can I spread the load if every sata cable that is coming out of my PSU has one female head.

What about molex to sata risers, are they reliable? Because I found some reliable dual sata to molex connectors : https://smile.amazon.co.uk/Cable-Matters%C2%AE-Molex-Y-Cable-Adapter/dp/B00VJ9V8NY/
