If you just getting started for mining then you should move this thread to Mining support board, many people with good knowledge on mining will answer your questions there.

The one displayed in the image is fine but the safety depends on the whole set-up.

How many PSUs do you have and their 12v rail power rating?
How many GPUs do you have and their power consumption or model?

Also, your 6/8-pin PSU cable should be able to withstand the current drawn by the two split wires.
Most "good brands" does.

this does not belong in support.

gpu mining mines alt coins and needs to be in altcoin mining.


You need to be sure you do not over clock the gpus.

If they all pull 130 watts you would be at 910 plus gpu and cpu and ram and fans say 90 total 1000.

I do not like rose will as I find they do burn out when pushed.

If you do 1000 watts that psu will fail in under a year.

I have mined with a lot of rose wills and 70% or less. is best for them.
so you want to pull about 840-900 watts with it not 1000.

i just checked the pinout and it does 12 pin pcie jacks.  they are more subject to over heating.

I would run six cards not seven.

It is single rail which is easier to mine with.

let's talk about  x7 GPU
Forget the wires, you don't even have enough juice to stably power those 7GPUs.
I'd recommend adding another PSU to power the other three GPUs, plus you wont be needing those splitters.

There are a lot of guides in the internet on how to setup multiple PSU rig.

example ,

I have power A will use all pcie for GPU

i buy second power B , i will use this power only for power Riser

So , power supply A for GPU's , Power supply B for only Riser ,
My mobo Asus b250 mining ( can 3 powers )
is fine ?

No, use PSU A to power MB and x3 GPU risers and pcies, then PSU B the other GPUS risers and pcies. Power A first, then B.

Either use an 'add to PSU' connector to link the two, or simply short the MB connector on psu B and switch it on second.

That way if your two PSUs outputs vary at all, it won't be your gpus in the middle.

Or simply run less gpus save the cost of a new psu. See how 5 or 6 gpus do earning money.

 Vs spending 100 -200 more for a second psu which can be easy to mis-wire.

If 5 work well and earn profit. he can add his last 2 with a lessor psu like this one.

this can run 4 gpus. so he can offload some from the rosewill   maybe do 3 with the rosewill and 4 with the hp psu

trust me the rosewill would rather do   600  watts then  840

  use 2 wires to the gpu and 1 wire to the pcie board.
 then use the data cable to plug in the mobo.      
  3  pcie wires per gpu   and a data cable to the mobo.  this isolates the 2 psu's and no shorts.

719 of that 1200 watt psu should be okay.

check once or twice everyday.

let us know how well it keeps doing.


A followup would be nice. As many rosewills don’t like doing 75% 24/7/365

but you are at 60% so I think you are good.

still adjustment until full test OC is not light work , i will talk you this week next few days when it 24h no issues ,

Software power readings are not accurate. Do not trust it. 70-80W is actually 100-120W before the PSU, not even at the wall. It is very important to measure power with something, even cheap power meter plugs are better than software, and it is quite important to know the power consumption of your GPUs, specially if you are close to the PSU limit.

I agree with everything that philipma1957 said, and I would also put 6 GPUs per rig, specially with a 1200W PSU.

that's fine per Rig 6 GPU i will do that

but do i need to buy new PSU or buy new PC mobo + ram + PSU?
Total 12 GPU

first rig 6 GPU
second Rig 6 GPU

Or buy new PSU for my Motherboard ?

Personally, I'm not a fan of mining rigs with more than 6 GPUs using risers, but since you are staring, you could just use the motherboard you have with one more PSU until you learn all you want to learn and decide what to do going forward

Yep i guess how . i have now Asus mining mobo
but have question here ,

Example
My power supply A will use it to power  ALL my x7 Riser by pcie cable
and my power supply B For all my GPU's x7.


So Rosewell power supply for the Risers
Evga power supply for GPU's

have issues here ?

The GPUs consumes around 20-35% of their power from the PCIe slot, and the rest from the 8-6pin connectors, therefore if you put all risers in one PSU and the rest on the other PSU, the load between them will be quite unbalanced.

The best would be to use 6 GPUs (both top connectors and risers) + motherboard in one PSU and the other 6 GPUs in the other PSU. Also make sure that the PSUs are below 75% load as philipma1957 suggested. This is true for any PSU if you want them to last.

So , 2 PSU with this mobo is fine then ?

https://www.asus.com/Motherboards/B250-MINING-EXPERT/


I read the manual say can 3 PSU , but i want make sure before buying anything

So do you tried 2 PSU same mobo ?

yes i have but you must wire correctly.

you need to isolate the psu’s from each other.

a pcie riser can do this for you.

  use 2 wires to the gpu and 1 wire to the pcie board.
 then use the data cable to plug in the mobo.      
  3  pcie wires per gpu   and a data cable to the mobo.  this isolates the 2 psu's and no shorts.
