New mining rig using EVGA SuperNOVA 1000 G2

[meltayef]

Hello everyone
i'm new to mining and trying to build my first mining rig
i have a EVGA SuperNOVA 1000 G2 and i'm going to use 6 RX 570 GPUs for mining
i have a few questions
is 1000w enough to power 6 cards with the motherboard/cpu/risers...etc
or should i just start with 5 gpus


second question is, in case it's ok to power 6 cards
since the PSU has 6x 8PIN ports for GPUs i can use each to power a single card
but then i'm left with powering 6 x risers
i still have 6 x 6 PIN ports on my PSU (says SATA/PERF on them)
is there anyway to power 6 risers using these ports? since SATA connectors are not safe what should i use?

Thank you guys in advance

A 1000 W G2 is enough for up to 5 RX 570's dual mining. If you undervolt the cards and reduce the power limit, a 5 card rig would be ~800 W at the wall dual mining. The EVGA 1000 W G2 has 6 PCI-E connectors. You can use 5 for the VGA power inputs and the other PCI-E connector with two 6-Pin risers using an 8-pin to dual 6+2 splitter cable.

For the other 3 6pin risers you can use a 3 Sata or molex port on the PSU with a dual sata/molex to 6-pin PCI-E adapter cable. Only connect one riser to each PSU cable.

Thank you so much for this quick answer

just one more question. since i'm using 3 6pin ports on the PSU to power those 3 riserz, is there any direct 6pin to 6pin cable or something to avoid using 2-3 converts on the way..since both sides are 6pin why convert to 2x sata/molex then back to 6pin


Thank you in advance

Thank you in advance

yeah
buy six of these and ignore the guy above you

but let me check that psu for you

it has 6 pcie cables  not sure if all are 2 headed

this says they are.

so take pcie cable 1 and attach the silverstone extender go to the riser with that and the 8 pin go to the gpu  it will do 6 gpus

make sure you have 6 pin risers

see this link  my way you skip the sata all together you use

1 24 pin cable
1 cpu cable
6 two headed pcie cables with the red silverstone extender

The EVGA 1000 W G2 comes with 4 single 8-pin and 2 8-pin + 6 pin pigtail VGA cables.

If you wan to avoid using any Sata/Molex connecotrs for the risers, you can use a 16 AWG 8-pin to dual 6+2 pins splitter cable with the single 8-pin PSU cables to power the card and riser on the same card.

18 AWG cable is only rated for a 10A capacity (120 W at 12V) and is too thin for using with 8-pin connectors that are rated for 150 W, but it's fine for 6-pin VGA connectors that are rated for 75 W.

This is what happens when you use 18 AWG cable with a 8-pin connector on a RX 580 when dual mining!

thanks for this reply
i'm not sure i get what you mean tho, it has 6x8PIN cables which will go for 6 gpus as you said
for the 6pin slots in the PSU (which i plan to use to power the riserz) only cables that are included with the PSU are 6pin to sata or to molex
my question was is there a 6pin cable with 2 male sides. 1 would go to the PSU slot and other directly to the riser

the one you posted has one male side, and 1 female side not sure what to do with it if both the PSU and Riser have female ports

not sure if my information are fully correct so please let me know if i'm misunderstanding something

thank you in advance

----------------------------------

Vann, so you're saying i can use 1 8-pin cable (along with the splitter) to power both the GPU and the riser

would that be safe? would the 150w that 8pin provides be enough for both the gpu and the riser?

AMD cards are power hungry, a relatively weak card like the 570 pulls a lot more energy than the 1070. It will outperform on Ethhash but that is so over-mined I have no interest in it. I don't think I'd want a GPU minign rig that brought in 0.001 per day.

The EVGA 1000W G2 PERF and SATA ports are interchangeable.

I ordered additional molex cables from EVGA and run 6x1070Tis through the 6 PCI-e ports and use 4 molex cables (3 cables to power 6 molex powered risers, and 1 cable to power the motherboard). You can also buy additional 8-pin+6pin cables specifically for the PSU. It's costly, but I prefer the safety of using cables specifically for my PSU and not using any adapters.

I don't use Sata cables for powering anything other than 1 SSD.

Well now I know what pay to get so that's good.
What is the best gpu for $$?mh/s ?

What is wrong with 0.001btc per day? Sounds good to me.
