Can i run 2 gpu's on this single cable with 2x 6+2 pin on it ? (noob)

I have a Cooler Master 500W 80 + efficiency PSU , it has 2x 6+2 PIN, but what worries me is that the 2x connectors are on the same cable (not separate) like on other PSU's ive seen. If i connect 2 gpus on it im planing on under volting them to about 75 W each. Is this gonna be doable or am i gonna fry the cables ?

What psu and what are the specs of your system? Psu as in the actual model not 500w+ bronze cooler master they have plenty of those.

 

You are only using one of them and then again a lot of psu's (even really really high end ones) do this as it's normally never a problem.

 

Also just a heads up but multi gpu gaming is beyond dead there is nothing to gain from it only things to loose.

First, why are you putting in 2 GPUs as SLI is (as Linus put it) dead. AS long as you don't go over the power limit on the 6+2 pin rail I don't see why not. But its most likely more worth it to just upgrade to a newer card rather than goof off with with 2 GPUs. What card are you sli(ing)?

If don't need 2 GPUs sell the one you have and buy a newer card

I am a human that makes mistakes! If I'm wrong please correct me and tell me where I made the mistake. I try my best to be helpful.

Again what psu and why those 2 cards? They can't work together and one will just sit there doing nothing unless you have a task that can use both (like rendering in blender).

PSU MWE 500W 80+, 

Ryzen 5 2600x 

2x 8GB 3200 Gammix 

Im not going to use them for dual gpu gaming. I got the amd card litterally for free and since im away on my job most of the time and i travel , i let my gpu crypto mine. So i just want to know if its duable to connect them both on the cable i posted above.

On a mwe probably bronze psu I'd say yeah but pushing it a bit as it's not the greatest of psu's at all. You do know that cryptomining on gpu's hasn't been profitable for a long time unless you have the newest top of the line stuff right? You will pay more in electricity than get from them.

Right now here im paying 30 US cents for KW/H , and im not even paying the bill (im just saying what i would pay). I mined 4 months on this 6 gb 1060 , i managed to scramble up 200 $ just from mining and im selling this 1060 and im probably getting a 1080. (i think) (used 1080 price here 300 $ )

Sure then go for it. Do keep cooling in mind as cards will be close to eachother.

As a blanket statement this is wrong and will vary depending on exchange rate and electricity costs. My 1080 Ti makes me about €1 profit (i.e. electricity cost has been subtracted) per day currently. You won't make bank, but can certainly be profitable on not-latest stuff.

 

I would go for a dedicated cable to each as typically it's 75 W from the PCIe slot and then 150 W per 8-pin connector. I would not be comfortable powering a 280 W 1060280 W 1060 and a 325 W RX 580 from a single 8 pin to the PSU. Your 500 W PSU possibly isn't enough to power everything under full load in the first place unless you undervolt or power limit them. Of course those are gaming numbers and not mining numbers, but I would upgrade the power supply first of all if you want to do this.

Missed the undervolting bit. It may be fine in this case.

The 1060 consumes about 120w and the rx 580 depending on the version sits somewhere in the 200-250w range. A mining bios for a 580 gets them to about 120w normally which is ok as op stated they would do this immediately then it's ok to do so. If not then yeah psu is going byebye.

Sorry to reopen this post, but i know the psu will handle the gpus , im wondering if the single cable that has the 2x 6+2 pin that will be connected in the 2 gpus will handle im worried about melting it.
