Does the tape not melt?
What kind/brand you are using?

Not that I know of. Any lights I didn't want, I just cover it with electrical tape.

Hey, yeah I had feeling connecting 6 gpus would be an issue.
My plan was to have 1 psu that can powerup as many gpus possible, so 6 cannot be done, how about 5?
Yes you are correct, the adapters will work fine for short term, but it will definitely get hot, so I won't go down that route.

I just wanted to confirm with everyone, my best option is to connect 5 gpus on 1600watts psu?
Just that with EVGA 1600G2, I was able to connect 4 gpus without an issue, it appears adding 5th gpu will be an issue as there isn't enough connectors. Although, there are now 2 x 6-pin sata ports available as I got the fans changed.

Do you think I can use 2x 6-pin sata ports to fire up the 5th gpu?

Thanks

Anyone able to turn off the red light on radeon vii ?

Ah yeah - I assumed maybe a 30-50w system power draw...  Everyone seems to be running celeron systems these days (or ryzen).  So sounds like you're closer to 225w/card - more reasonable.  And yeah, I benched on an unloaded PC w/ a 1Kw platinum PSU, so possibly a touch higher on the efficiency curve.

Though cheap isn't always best in power supply situations! The best idea if you want cheap is to use commercial server psus and breakout boards, cos they're designed for the job and cheap as chips. They are noisy tho... 

My rig has 4x 4000rpm fans (or 7x 3500rpm fans), just the mobo + fans with no gpu attached is ~140w.

Even so, it's less efficient that yours. Might be my psus hitting 90%+ load, I use the Evga 1600t2.


That's just the hotspot temp? If so that's within spec. Mine are 70-75 degrees in MSI AB, but 85-90 hotspot temp.


At 1500 core you can also go way lower with voltage, or bump up the core. Many of us run 850mv, and between 1500-1575 core for 80-82mh/s

Yep exactly. Though they are "cheap Chinese PSU", they are around 4 times cheaper than the equivalent wattage PSU, and have more cables suited for mining use.

LOL, there are so many PSU´s with 12 or more PCIe connectors XD

Of course you can run 6 (or more) GPUs on 1 PSU - just not w/ out of the OEM box cables.  You can buy a second cable package from EVGA directly (not cheap, and wasteful,) tailored after-market cable packages from places like cablemod.com which are made for specific PSUs (slightly cheaper,) or no-name adapters off of amazon, etc (cheapest by far, but requires careful attention.)


Power use spikes above PSU cap can be easily prevented w/ GPU power limit if necessary - or just proper voltage tuning.  PPTs will ensure GPUs reset to desired settings.  Someone would have to make some colossal mistakes to have a PSU OV/OT shutdown - esp on a recurring basis.


This is backwards.  The longer full-load runtimes you have on the PSU, the *more* need you have for increased efficiency.  Does a gamer need platinum - not really.  Does a miner who runs 24-7, at or near capacity - absolutely if they want to save on power costs.  Is Gold good enough? - maybe... Really it comes down to a calculation on the premium you pay for the upgrade, vs the saved power costs over the life of the PSU.


6-to-8 is not necessary for EVGA 1600s (though under the right circumstances, can also be fine.)  As I wrote earlier, I have been using numerous 8-8x2 splitters off of amazon w/o problems for over a year.  It just requires diligence in making sure you got the right part, that the parts are in good condition, proper attention to your GPU power use, and some early monitoring to ensure heat is under control.

My Radeon VIIs run hot!  I have the mem at 1500 core 975 undervolt 875 and they still get up to 80 degrees in my shed with fans blowing on them.  Not sure I made a wise buy my hash rate for eth is down to 75.  80 - 90 make it a deal but I don't think it can run long at 85 degrees. 

You cant connect 6 GPU's on 1 PSU. There is no PSU on the market with 12 PCIe connectors.

EVGA has 9 connectors. You can run 4 GPU's and if you use a cable-mod (CPU to PCIe) you can run 5 GPU's.
(SuperFlower is the same as EVGA. If you dont need the 2000W, better go with EVGA!)

Seasonic Prime Gold 1300W ATX 2.4 (SSR-1300GD) has 10 connectors. With good undervolt you can run 5 Radeons. But with every energy-spike, every GPU-reset, everything which dont stay optimized will shut down that PSU.
(Corsair and CoolerMaster also have PSU's with 10 connectors. But in terms of quality and warranty they both stays way behind EVGA. Even Seasonic is not the best pick.)

So better split your load to 2 PSU's with a bit of room. If you need for example 900W for 3 GPU's, buy a 1200W or 1300W PSU. The 1300W Gold EVGA PSU's are mostly cheaper than the 1200W xxx PSU's, so the 1300W is the better choice. No need for Platinum and co, if they are only for mining.

Life saver tip: NEVER EVER use cheap 6-pin to 8-pin PCIe adapters to connect just 1 double cable from your PSU to your GPU!!! They will get very hot and if you are unlucky, you can burn down your home!
Another tip: Don't use cheap chinese server/mining PSU's. Protect your investment with quality!

Minimum 1600W 80+ gold.

I like Superflower PSUs, I have a 750W and a 1000W.

Hey, anyone knows the best PSU to purchase for connecting 6 GPUs?
Just that I don't want to be short of wires as VII uses 2x 8-pin cables.

Thanks

Indeed, reward vary because of the difficulty, but not the HR.

Regarding the block reward decrease, creating a little bit of scarcity is not bad for the price. So less reward but a higher price gives the same in FIAT. If you HODL your mining rewards, it's different.

But the difference if the difficult get decrease and there will be more miners in the blockchain. Then changed of algo is not giving a huge impact but the more miners and that will decrease our profitability whatever if you will get the same hashrate and your profit will decrease. The worst thing when the block reward will be decreasing too.

The same if the algo doesn't change.

Something seems to be sucking up power unnecessarily in your setup - I ran same settings but w/ my mem just a touch lower (935), and only saw 215w/card - looks like you're at 240-245 for some reason, which is generally more in-line w/ the 90Mh/s config.

So lets say the hashrate will be around 82 MH. What will it be in 3 years?

This means tha ASIC Innosilicon A10 miner is only twice as efficient as 6 Radeon VII, it's much more expensive and if Ethereum goes Progpow the VIIs will keep mining ETH while the ASIC will be a noisy door holder.
