Alternative PSU for Antminer L3+ ?

[mustangy]

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.

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?

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.

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

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

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++ (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. I prefer to use a PSU tester 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 is a good substitute though.

Seems interesting. Are you an specialist in this field?
