if you take a sata cable  with 2 sata jacks and run 1 riser with that adapter it should work. just 1 riser.


if you take two separate sata cables and feed that adapter into 1 riser it would surely work.

Usually I buy a 400 or 500w ATX PSU for just the MOBO, then as many HP DPS-750RB server PSUs as I need. Each one can feed 2 RTX 3080's, 4 RX 6800's or 5 RTX 3060's. The breakout boards will have enough cables so that I don't need to buy 6-pin splitter adapters.

That MZ490 gaming motherboard is a good choice for mining and its less cheaper than some mining motherboards, you are free to go after this one because I have the motherboard and it works beautifully, i can see that you are trying to buy cheap parts, I am with you on cheap motherboards but not PSU. .. BUY cheap motherboards and buy high grade PSUs, this is the best combination.

Bringing another rig in the picture would require more power to prevent the breaker from tripping.
I'm sure your well aware of this, I figure I'd mention it because it good for redundancy.
Assuming this is a home project, maybe look into wiring another sub-panel and install a Raptor PDU or Tripp-lite 240V PDU.
Also, sound and heat will go up, it might be necessary to think about a temperature controlled wall exhaust fan.

Lastly, I suggest building your own frame or enclosure.

It seems you are determined to stick with 5x PCIe slot motherboards only, you aren't leaving a room for any future upgrade which wrong, it was the type of miskate I did when I build my first rig, always go with extra space motherboard, mining is addictive sooner or later you will want to upgrade.

That's a LGA1155 motherboard B250C I guess and it supports 12 graphic cards, you will only need to plug in your risers USB cable without the PCIe x1 adapter, its a pretty good and cheaper motherboard for mining but since you talking about LGA1200.

If you are sure about the quality assurance of this Hydro G Pro PSU then proceed, its just funny that I am hearing the name for the first time but there is always a first time for everything, you will need to either buy a Add2PSU to use two 1000 watt power supply or go the old version way ( paper clip ).

1. 8 gig ram is enough for your mining rig, I have 6 gigs in mine (4/2 GB RAM) and it runs well.

2. You can use any CPU with your mining rig, low end CPU like Celeron are good because they consume fewer watts, since you won't be doing CPU mining it's a good pair.

3. Find the Asrock H510 motherboard, this is a mining build motherboard with 6 PCIe slots, meaning you will have an extra empty slot to add a GPU later



There is also a BIOSTAR TZ590 which is also a dedicated mining motherboard with more slots and its LGA1200, this has 9 PCIe slots for GPUs



These motherboards are available on Amazon right now, Good luck and happy mining.

You will be running some higher-end graphic cards mate, they need a stable power supply or you will put them at risk, fins Corsair, Evga or OCZ power supply, I have killed a GPU with a Chinese 1200 watt PSU before, do not repeat the same mistake.

PSU is the last thing you don't want to cheap out on

hi

am planning to buy new components for a new rig build (before i had two servers lying around so used those for my previous builds) and I have a decent experience putting the parts together...

the GPUs am having will be 2x 3090s | 2x 3080 Ti(s) | 1x 3070 Ti ((ALL EVGA))

from what am hearing the lowest CPU, RAM and Board are needed, i mine using NICEHASH, and windows 11, is 8 GB of ram enough ?

as for the CPU is this ok or can i get away with something cheaper ? Intel Celeron G5905 LGA 1200 (45$ USD)

this is the frame am getting will it accommodate two PSUs and is the material OK ?

What board will support 5x PCI-E slots ? coz its kinda tricky sourcing those on LGA 1200 !...

how much wattage will i need spread across 2x PSUs ?

one final fatal question 

I will probably need lots of 8-pin connectors, if splitters didn't do the trick, can i get away (for those high end cards) with 4-pin molex connectors (not sata) to power up the risers ?...


thanks...

The best card manufacturer for Nvidia is Evga but the problem is that the temperature problem is in every manufacturer as they are produced for gaming in the first place and the memory temperature does not happen while gaming.You can add extra cooling to such cards,a 6 Pcs fan next to your cards can make that memory temp go to 100c or even less than that in case you don't want to redo another tedious task like the one of changing the thermal pads.

There are the CMP version cards which are expensive enough but they are made for mining and I have not read about any problems for those cards so far.
