Which Is Better?

[CalifornianKing]

Looking to get a 1000W PSU so I can run 3-5 3000 series GPU's so I was wondering which one to get. And as I am writing this, I am realising that 1000w will not be able to run 3 GPUs. My question, is it possible to take 2 smaller PSUs like 2 850Ws and use them instead? Sorry for the dumb question, am dumb and superrrrr tired right now.

Get a power supply tester or just use a paperclip. It's pretty darn easy to do, and a lot of miners have things like that set up.

wtf is that. I've never built a PC hence my confusion. I am just asking if it's possible to run 2 PSUs without damaging the cards or needing another MB. I'm trying to cram it into on PC btw. 

edit

I also don't have anything other than a 3060ti purchased hence why I am asking so I know what to purchase.

Is there a difference between link compability and regular? Found a 1200W corsair without "Link Compability" for a decent price..

If you've never built a PC I wouldn't really recommend trying to build a mining rig, since getting it all up and running can have some issues that are not friendly to beginners. If you are dead set on doing it, get one of these for the second PSU

https://www.amazon.com/CRJ-24-Pin-Supply-Jumper-Bridge/dp/B01N8Q0TOE/ref=asc_df_B01N8Q0TOE/?tag=hyprod-20&linkCode=df0&hvadid=494674935091&hvpos=&hvnetw=g&hvrand=13745812985190836670&hvpone=&hvptwo=&hvqmt=&hvdev=c&hvdvcmdl=&hvlocint=&hvlocphy=9003821&hvtargid=pla-884349815002&psc=1

EVGA PSUs come with them in the box, and basically turn the switch on just before you power the system on, and turn the power switch off just after you turn it off. If you leave it on, it won't hurt anything, it's just not ideal, and if you leave it off the system will just fail to boot. It won't damage the GPUs, I've gone it with 2 different PSUs powering one GPU (trying to test a 3080 FTW when I only have 2 600w PSUs on hand). You can also make one of those out of a paper clip by sticking it in the proper pins (I forget which ones off the top of my head, but it's pretty easily found on google). I wouldn't recommend that for a long term solution.

I am not building a mining rig. I am building a gaming pc that will just be a covert mining rig basically. I'm gonna stick 2 internal gpus on this MB

https://pcpartpicker.com/product/fyRgXL/asus-prime-z490-p-atx-lga1200-motherboard-prime-z490-p

and I belive three external ones outside the case on the floor or something under my desk at study hall.... I will also have help building the PC and will only put in one GPU (3060ti) since that's all I've got currently.

Anything more than 2 GPUs to mine is a mining rig. Running more than one or two GPU to mine in windows can be a nightmare to setup

 Nicehash? Plus I have some mining experince when I had my 2080 gaming pc (got stolen by my uncle) and so I can figure it out if it's just opening that file thingy and putting in the wallet to mine to, the pool, and the GPU's? Thanks for your help, I;ve got just one question, two PSU's fit into this build/case? 

edit

How much wattage should I get for 5 3000 series cards in that setup?

Mining with nicehash isn't usually a great idea, you're better off finding a different miner. That case can't fit 2 PSUs unless you do some serious case modding. I'd have the second PSU on the outside, and just have it jumped and all it's cables outside with those GPUs you decide to run externally.

I'm not gonna tell you not to set this up, it would certainly be an interesting setup, but I'm just gonna tell you it isn't the best idea.

Alright.. Ill think of something. Would a 1200W PSU work? Would it run 3 3000 series cards? I found a $420 one (corsair) and I'm not gonna mine w nicehash that much. Or should I just stick with 3 gpus?

That motherboard doesn't support 3 GPUs without some modifications, and that case doesn't support 3 full size cards unless you can find a board with 4 PCIe 16x slots (just so you can have enough spacing for 3 dual slot cards). 2 cards would be the limit for doing it easily in that case, and for that a 1000w would be fine, especially if you undervolt the cards slightly to help improve profitability. Unless you want to try to find a different board and a different case with 8 expansion slots, 2 would be the upper limit without doing something crazy.

I was told I could have several external cards...

edit

on that MB. So is two internal and 0 external the limit? cause the 1000w should handle a 3060ti and 3080 and eventually 2 3080 easy

external would be possible, it's just that external GPUs are kind of weird to set up. A 1000w would work for 2 cards, but 3 cards would push it, and you would be better off with a 1200w or 1300w

[CalifornianKing]

Alright. I'll stick with 2 internal for now. Still $20 a day with 3080s. I've got to crunch the numbers though. Thanks! I doubt I can get a case to fit 3 internals. I can always get a external later 

edit

with a PSU like you suggested w the amazon thingy

Just answering to the question of whether you can run multiple GPUs off multiple PSU, yes, it's possible, you short the green and black pins on 24-pin connector (essentially what so called PSU testers do) to trick the PSU to think that it's powering the PC and then you can power the GPU with it's PCI-e cables as usual. Just make sure to get a PSU with DC-DC as cheap group regulated PSUs will have troubles keeping voltages in specs with unbalanced load (no load on 3.3\5V and high load on 12V). Another thing, if you're going to mine on 3-5 GPUs off the same motherboard, make sure that this motherboard was designed to deliver power to multiple PCI-e connectors at once, as i imagine common motherboards don't have much beef in the PCB power planes to deliver ~100W of power to smaller 4x PCIe slots as they don't expect them to be loaded that much, and risers if you plan to use them will only exaggerate this issue.

Alright thanks. The MB im using was recommened by another member here, and he mines on it so it should be fine.
