Anyone have recommendations for a PSU to use aside from bitmains apw3++ ? Looking for bang for buck / efficiency

Bought these, they're freaking sweet. More uses and better bang for buck than bitmain antminer apw3++ / other Power Supplies

Best PSU for one L3+

Best PSU for 3 L3+

Get a PSU that will supply 10% more power than needed in the Gold/Plat category, and then look at reviews. Don't skimp on a PSU tho. If you get a cheaper PSU to save $20 and it fries your 3k miner, did you really save any money??

I heard the EVGA 1050w GS is good for L3+

If it were me id buy top notch.  If you have a $200 miner and if frys meh so be it.  These miners are gold right now and you should be supplying it with a proper psu, worth the extra money you will make it back quickly right now

What do you consider top notch?

I'll check that out right now thanks for the tip

Any other recs?

The kit manufacturer sidehack here at the forum has them for sale.

We get this question A LOT. Here's a guide we like to give people when suggesting a PSU for people who don't want to run the brand new APW3++ (https://www.amazon.com/AntMiner-Power-Supply-1200W-Connectors/dp/B0733KMB2N/ref=sr_1_3?m=A1LBZI6C51C6OJ) (which also supports 110v now):

• Obviously, your PSU must have at least nine 6-pin PCIe connectors. Yes, the 8-pin (6+2) connectors work too.
• Always plan to use 80% or less of the total available power when using a consumer-grade PSU. If you need 800W, then purchase a PSU capable of 1000W or higher.
• Only use PSUs that have a single 12v rail. Mining devices require very high amperage and cheaper PSUs can't provide the full amount over all of their connections. PSUs with a single 12v rail can supply their full output through any of their 6-pin PCIe connectors.
• Only use PSUs that have Gold or better efficiency ratings. Efficiency matters a lot in the long run unless you have free power.
• Don't forget that consumer-grade PSUs do not "turn on" without jumping the right pins on the 24-pin ATX connector. Here's a quick how-to (http://aphnetworks.com/tutorials/psu_paperclip_trick). I prefer to use a PSU tester (https://www.amazon.com/Insten-24-pin-Power-Supply-Tester/dp/B005CTCD6S) instead for aesthetic reasons.
• Always be aware of your circuit's maximum amperage as well as how many amps are being used on the circuit in total. Remember, Watts = Volts * Amps, so 800W / 110v =7.27a.

Normally, we'd recommend the EVGA SuperNova 1050 GS, but they're out of stock almost everywhere. The EVGA 210-GQ-1000-V1 (https://www.newegg.com/Product/Product.aspx?Item=N82E16817438062) is a good substitute though.

This would do well: https://www.newegg.com/Product/Product.aspx?item=N82E16817139129

Get good quality PSU the cost is worth it and covers your butt in case of power surge usually.

Honestly, anything that is 80+ gold / platinum / titanium rated. I personally take that 80+ rating over brand.

L3+ need 9 connectors. I can highly recommend this PSU and the seller:

Work well on all my 26th L3+ and seller is very solid (delivery around 7 days).

received my L3+ today, checked the Antminer PSU Power Supply and noticed some white "leaked" texture at the back. can someone tell me if this is normal?

stick with bitmain psu they are not the best in market but efficiency (this save your kWh bucks) and stabilty is still best
i used delta 2600w hp 2850w but i don't know how bitmain find out the dead hasborad is had 29v instead 12v and did not replaced.
before i replace 6 under warranty but the first time they replied that PSU over voltages the hashbord after 90 days they replaced but said first and last will not replace again.
i dunno how the fck they found it

You have a model number / link that’s interesting ???

One PSU came DOA from Bitmain, im looking for an alternative.
RMA @BM will take 3 weeks or more i think.
Is there a legit shop for the L3+ - HP-breakout-board from gekkoscience ?
Parallelmining is in cali, that would take too long to ship compared to Bitmain.
Other option would be buying a normal psu and buy some more 6-pin connectors.
The 6-pin should fit into the 8-pin sockets, i think. Right ?  ???
To get the psu running i would have to bridge two contacts on the 24-pin i think.

All in all very workaroundy danger-soundy  ;D

I recently ordered one of these dual 120V 2400W PSU's for my ASRock H110 Pro BTC+ build and have been very happy with it.

http://www.panto-tech.com/products/206-110v-260v-power-supply-2400W-for-miner.html

It has 18 PCI-E 6+2 connectors that I use for the GPU VGA power inputs. It runs quiet and very cool as long as you don't run it at more than 50% of the capacity. When you run it at more than that, the fans get progressively louder the more wattage you pull from it. Shipping via DHL direct from the manufacturer was very quick. Total cost through PayPal was $181 shipped and I got it in less than 4 days.

The same manufacturer also has the same PSU with only the 18 PCI-E connectors and it's about $30 less, so I think that may be a better option for a L3 since it only uses the 6-pin power inputs.

BBT did a review of the PSU and has run it through various tests in his recent live streams and it's held up well. We'll see how it holds up long term, but for $150 shipped it's a good deal and solves the problem of not having enough PCI-E connectors for larger builds.

Thanks for the hint.
Im a bit cautious with that PSU, Gigabyte is usually not a fan-manufacturer but rather a powersupply-manufaturer for PC-equipment.
So this device looks a bit "salvaged" and the way they cut the edges is looking self-made.
When i order in china, i might order one if they are really turning out safe.
Would be a shame to save money on the PSU which then toasts two miners for 5K.
But maybe im too careful ...

it is APW5 efficent and quiet under 110v also.
but no more production because was expensive double or more.

I am running 24 L3+ with HP DPS-1200FB power supplies. Ordered 120pcs back in October 2017 when they were still around or below $20 USD. Since then they are running 24/7 and I have only good things to say about them. Of course, you'd need to add a breakout board with 12 or 15 PCIe ports and 6pin cables.

If you really need platinum rating you can go with HP DPS-1200FB-1 version.

I contacted my supplier last week asking about those PSUs and it turns out more ppl figured out they can use server-grade PSUs for cheap and now prices are within $50 - $80 range. It's also getting harder to get a decent amount (50+ pcs.) from one vendor.

One thing to remember - those are "pulled" PSUs which means they were probably running 24/7 in some servers for the past couple of years. I would advise replacing the fan and cleaning the insides.

Here's a photo of my setup:

I am interested in using the DPS-1200FB as it looks around half the price as APW3++. Have they held up with low error rates? Also, do you happen to overlock the l3? I overclock mine to 600 Mhz which uses 1000 watts.

That is 100% normal. It protects the components from each other and various shocks like dropping the PSU. Its a good thing. If you need more clarification just google "white goop in PSU" You will find thousands of people asking the same question.

This good to know. I will stick with stock until the warranty runs out and then look at some platinum power supplies for my L3+'s

Seems interesting. Are you an specialist in this field?
