Thank you for your response, makes sense!

Thanks guys for the responses, despite the fact that most are in response to the other person. 

I've seen the shared chart with maximum wattages a few times and I know I'm not exceeding them. But here's the question:

Is the load evenly distributed across each cable, or is possible that the GPU may overdraw from one cable and not the other?

So if my 3080s are each hooked up with two 6+2s, and one part of that cable powers the riser, is it possible that the card will draw most of what it needs from just one cable, thus potentially overdrawing the cable?

Hi everyone,


I've followed all the advice on how to safely set up PSUs and power your GPUs to ensure there's no fire hazard. However, I can't find definitive answers on a pretty simple question in ANY of the articles or videos.

I am running RTX 3080s, and they require THREE 8pin connectors from the PSU. The PSU supplied cables have 8-pin to dual 6+2 pin Y cable. As a result, two cables are needed to power a single GPU, and we have FOUR 6+2 pin cables from them. However, we only need 3 to power the GPU, so can the remaining 6+2 cable that dangles off to the side be used via a 6-pin female to 6+2 male extension to power a riser?

Thank you so much for clearing this up.

Received an Aorus Extreme 3080 - it throttles if it goes above 53-55C, dropping as low as 65mhs, but generally floating around 70mhs. Setting fans at 100% and opening the window helps to bring it back up to 87-95mhs. Generally avoid this card, despite it being the top tier card from Gigabyte. They're all terrible for mining it seems. Mind you, I run on VERY conservative +800mem OC.

The 4 MSI Suprim Xs I have are OK. 8 GameRocks are most consistent, albeit they run hotter than most.

I suppose you're speaking to those with 1-3 cards, how are we supposed to watercool entire rigs? 

I did not play around with the BIOS, I assumed I just didn't get lucky with the 2nd one. They can push to 99, but I'd rather prefer stability over the extra 2-2.5H. Running them at 96 and 94 respectively.

Updating everyone on the results after updating to HWinfo 6.42:

GPU temp followed by Memory Junction Temp:

1. GameRock: 66C, 96C
2. GameRock: 63, 98
3. GameRock: 55, 92
4. GameRock: 66, 106!?
5. GameRock: 52, 88
6. MSI Suprim X: 40, 90
7. GameRock: 43, 76
8. GameRock: 62, 94
9. MSI Suprim X: 51, 98
10. EVGA FTW3 Ultra: 62, 96

Clocks: -500 clock, +1000 Memory on all but number 7 & 8 sitting at +800.

Is this expected? Someone mentioned that the temps aren't for actual VRAM here, but reflect something else entirely? Im worried this isn't normal?

As for my room temps, it's around 20-25 I imagine. I dont have a thermometer here unfortunately.

Updating the thread:


MSI Suprim X: Have 2. One will cause a crash at more than +1000 memory, hashes around 92 only. The other one is perfect at 99-100mhs, 35-40C on 1200 memory -500 clock, 60% PW 60% Fan
Palit Gamerock: 6 of them in total, all run 98-101 at 200W, by far the best card for mining. +1200 mem, -500 clock, 60%, 60%

I would like to add the following information to help with the thread:

MSI Suprim X does not throttle. Varying 97-104mh/s with +1200 memory -400 clock, 70% power, 70% fans.
EVGA XC3 Ultra Gaming - Does not throttle. Same settings as MSI above.

Will be testing the following over the coming days:

MSI Gaming Trio
Palit GameRock, 3 units (on this thread it was mentioned it doesn't throttle, so fingers crossed)
MSI Suprim X (the 2nd one so will be able to validate with confidence)

Could you please tell me which model EVGA you have? I've tried the X1 software from EVGA and mine isn't showing VRAM temps.

Hi everyone! Thank you for taking the time to provide insight into this.

I'm fairly new to the mining world and just started out with a small 5 GPU mining rig consisting of 3080s. I mine using NiceHash that mostly chooses the Hashimotto algorithm as most profitable. Currently, each card makes about $8 or £5 a day in profit. It's all very promising and great, but then I became aware of the ETH shift to PoS from PoW, thus making mining on Hashimotto obsolete/less profitable?

I am struggling to consolidate what the market or experts say will happen to ethash based algorithms and the profitability of mining on them. The timeline seems to be everything from a few months to at least a year, perhaps a couple until a full switch to ETH 2.0 is completed. Some suggest that ETH 1.0 will live alongside even after the 2.0 launch and the mining will remain viable on 1.0

I am not very knowledgeable in this, so I would be very thankful if someone can provide their insight who has their ear close to the group. Things I am trying to determine are:

1. The longevity of mining on Hashimotto algorithms or any algorithms on the ETH 1.0 network
2. The estimated timeline for a full switch, should PoW become obsolete after the switch
3. The viable alternatives mining outside of the ETH

Thank you so much for reading, and thank you for your help!
