Topic: Building a rig for 3080x2 and 1080ti, psu load, rig frame choice? (Read 56 times)

Thanks for the tips.  Yeah i was using worst case wattage scenario, its how i arrived close to 1200 watts.
Ill just do the dual psu with the adapter in between and make sure i'm not splitting a single component across two psus, but just evenly distribute things.

I hadnt heard about the 40 watts in the riser with the 3080?  Does this mean i should make sure things are a certain way?  I already know the pcie cable should be split to the card and the riser (on the same line).

For the rig itself, i think i'm going to switch to the 6 gpu veddha model ($150ish on ebay) https://www.amazon.com/gp/product/B091D2H3F7/ref=ox_sc_act_title_2?smid=A2BTFENBZ612M&psc=1
Though i guess if i were willing to figure it out i could get wood and make my own, lumber in the usa is a bit expensive right now though.

Side note, Eth mining coming to an end is a bit of a concern or the difficulty bomb in july they keep mentioning, but thats another story, i would have to hope that there will be other coins (not in the eth family i guess) that could have "potential future" profit if this comes to pass.

I am running a few 3080s and the bespoken 225 Watt is correct. But this is only while mining ETH.
Better you go for a 1500 Watt and up powersource.

In the case ETH mining comes to an end or another coin (with more power usage) with more income shows up,
you can just go on mining and dont crash your rig.

Dont forget that 3080s take over 40 watt out of the riser. This can cause trouble.

Dual PSU or single 1200 watts power supply, whichever you go with is fine it depends on what you can get in your country

Use eBay or Amazon to find metal rig, I don't use metal ones I use wood and do the whole building myself

Rtx3080 will draw 224watts and a gtx1080ti will draw 210 to 230watts so I don't understand how you getting 1300watts, all this power draw should be around 750watt to 800watt so yes a 1200 watt power supply will do just fine

Since you already have a 850 watt power supply then get a extra 850 watt power supply

Im trying to narrow down choices on whether to go with dual psu's or buy one large one for my setup.

Im also struggling to find a metal rig on amazon that will house both the full atx and two psus (if i do dual psus).
Im going to use my 6700k/asus z170a main "server" machine/board as the mining machine (it runs plex/media/main files here), its on 24/7 so i figured it made sense.

Initially ill just have a 3080 and 1080ti, but i plan on adding a 2nd 3080 in a few weeks.

I've run the numbers on online calculators going with the full load scenario and adding 150, this seems to top out at 1175 watts (so the recommended is an 80% 1300 watt, typically $299 cost but now $476 single psu).

I already have one msi 80 gold 850 watt psu, if its safe enough i guess i could just add the second psu and use one of the dual adapters to connect the second?

I assume with that i dont need the motherboard "split" cable i see referenced which often in the reviews is mentioned it caught on fire.

This is the rig i initially found on amazon, sounds as if it may fit two psus, but only if one is sideways and dangles:

This is the dual adapter: https://www.amazon.com/gp/product/B08F9WGLP2/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1

Anyone have any comments on this setup and if it makes sense to go with a dual psu's here (and safe?), i guess safe if i make sure individual components are powered from the same psu (not split up)?
Thanks in advance
