Was interested in running two 821's with an APW5. Spec looks like it should work, but imagine my pdu might be the bottle neck with just 12A outlets.
Looking at a new PDU with 16A outputs but hoping for some advice before the plunge.

Thanks Styme.
My biggest concerns are start up draw as I'm looking at a switched pdu. Currently one we can source is with 16A outlets and is in my price range. I want to be able to start and stop these as needed. I run them -2 already but imagine start up draw is considerably more than HF has posted. Maybe I'm wrong?

I dont think the power draw at start up is that extreme, can't say I've ever measured.
Just for an idea though it would need to be about 3500 W at 220 volt to trip a 16 amp switch, which is almost a 50% increase.
You could also use the controller to soft start/stop the miners if you're really concerned.
Edit: Just double checked the specs, does your PSU have enough power connectors? Pretty sure the 821s take 8 a piece, and the psu only has 14.

Some APW5's have more than 14, mine have 20 connectors. I've been running 6 821's on 3 APW5's since the first batch of 821's non-stop, no problems at all! Since around mid-July I've been running them with the settings below, 5/6 are running above 11TH/s but consuming around 1080W! Run much cooler with these settings. --avalon8-voltage-level -2 --avalon8-voltage-level-offset -2

forgot I have a few of these lying around. thoughts? Never used them on an asic before.
Can't say I've ever used them. The concern would be overloading the cable that you are splitting. I'm not sure what wire gauge they are. Might work but probably worth it to pick up another PSU.

Probably, I did already order the splitter and an extension and will put it on when I have time to watch the miners physically.

Works like a charm with the equipment i ordered. The spade style would have been a better choice though. No need for the extender with the splitters.

One more note don't use a splitter on the top 6pin's of the either board they get pretty warm. I imagine in a warmer climate they would damage.
