Trying to find a good, reliable source for buying 1800w PSUs in bulk, somewhere in NA. Wondering if anyone have some suggestions they can share. Thanks.

Have some extra 921s and 2000w PSUs I'm looking to sell. All the items are brand new, still in original packaging and have never been run before. Shipping location from NB, Canada. Prices are $CAD.

921 - $550 + shipping
2000w PSU from raptor-power.com - $170 + shipping

I also have a few CryptoSlayer+ 208V PDUs, from raptor-power.com - $415 + shipping


Would prefer to be paid in BTC but I'm open to other options.

Selling some extra Avalon 741's I have. Completely new, still in original packaging. Meaning they include the Auc3 connection and wiring. You will need a separate controller(pi) as well as a PSU(Can supply these for additional cost). Shipping will be extra, no taxes since CRA labeled my company as a financial service.

Looking to get $175 CAD /unit, will consider bulk deals if you're looking for a large quantity of them. BTC/ETH or wire transfer only.

Based in Canada.

So I have:

3 phase entrance

240v lines

125amp panel with some 20 amp breakers going to some plugs

Avalons 741s

15 amp 1600w power supply(Sorcerer's, from Canaan)

7.8 amp 1400w server PSU

When I set up a 741 using the sorcerer PSU, each line is reading around 6.3 amps(13 amps total), so pretty much in line with what you would expect from a 15amp PSU.

When I set up a 741 using the server PSU and a breakout board(x7's from parallel) each line is reading close to 7 amps(14 amps total), meaning my server PSU which is rated at 7.8 amps @ 240v is pulling well above what is should be.

What could be the issue with these? Is it possible there is an error with the actual wiring? Or is it more likely that there is a mistake with the labeling of the server PSUs and they are rated closer to 15amps @240v? Pulling my hair out trying to figure out what the issue is. Was expecting to double the number of Avalons im running by putting in these server PSUs which were suppose to draw 1/2 the amps of the Canaan ones. But they are actually drawing more and I feel like I'm going backwards. My electrician says the problem is the server PSUs must be labelled wrong. Just trying to get second, 3rd, 4th opinions on what is likely to be the issue.

Appreciate any and all thoughts
Thank you.

Anybody have some good experience they can share for monitoring Avalon's? I'm running 25 controllers and trying to optimize the management of them. I tried using their management software(https://github.com/Canaan-Creative/Avalon-Management-System) but just couldn't get it figured out properly. Would appreciate any/all thoughts and suggestions. Thanks.

Anyone know of some companies for sourcing large amounts of PSU's? Looking for an option for large scale purchases of 1k+ units.

Looking for some help on sourcing 110v power supplies for a large amount of Avalon 741s(numbering in the hundreds). Anybody have suggestions on NA suppliers who may be able to supply these units? Would appreciate any thoughts/leads/help on finding someone for this.
