Thanx okay the top one can be found for 50 bucks I have 2 of them you can certainly do 3 s-9's and in the winter with colder rooms maybe 4 I will give you a link for cheaper price on them https://www.ebay.com/itm/Genuine-HP-EO4501-Server-Power-Distribution-Module-228481-002-Two-Extension-Bar/122800749398?https://www.ebay.com/itm/Hewlett-Packard-HP-EO4501-Power-Distribution-Modular-PDU-Control-Unit-228481-002-/263163099707? more info https://bitcointalk.org/index.php?topic=2192299.msg22020934#msg22020934 as for running 4 vs 3 3 is easy peasy 4 is iffy I don't know your power volts you could be 218 to 242 volts on a full draw and you can't tell until you hook up the gear. and if you are in a commercial spot you could be 208 volts these are 30 amp pdus de rated to 24 amps for safety so you get 6 amps an s-9 6 x 208 = 1248 watts which won't work 6 x 242 = 1452 watts which may work s-9's sold the last 3 months were 13.5 th and 14.0 th If you grabbed 13.5th they pull less power and within the 13.5th group some are better then others so 4 per pdu on a 30 amp circuit is maybe I can do it in the winter but in the summer warmer weather I can not. I run 237 to 242 volts on full draw found another one https://www.ebay.com/itm/HP-Powerware-Dual-PDU-Rackmount-Assy-24A-8-outlet/172997481559? this is also good https://www.ebay.com/itm/APC-AP9570-Rack-PDU-Basic-1U-30A-208V-Surge-Protector/263341497055? that is 5 so far which will do 15 to 20 s-9's all cheaper then what you linked more https://www.ebay.com/itm/APC-208VAC-24A-50-60HZ-10-OUTLET-1U-BASIC-RACK-POWER-DISTRIBUTION-UNIT-AP9571A/253248986252? I also have links for psu's and for power cords Title: Re: Which PDU for S9s? Post by: miner6464 on November 25, 2017, 02:49:06 PM Thanks for your help!

Post by: gsav6 on January 17, 2018, 02:18:57 AM Hey man... Hate to resurrect an old link. I'm here in NJ also and have a few s9's on the way. I want to iron out electric stuff asap. I nought bitmain psu's and will likely have a 220 line ran with a 30amp breaker. I ordered 2 miners but may pick up another 2. Is there a pdu or pdu manufacturer you recommend over another?!?! Thanks. Gabe
