Server power supplies from reputable makers can last a very long time.
Delta isn't as well known for their power supplies as their "OMG THAT'S A LOT OF CFM BUT LOUD" fans, but they have been quietly making some of the best in the business for a long time - and many "Dell" "HP" etc server power supplies supplies are Delta-built.
Topic: PSU for Antminer S9 (Read 1644 times)
i was reading about PSU from Johnnyguru (http://www.jonnyguru.com/). so many things can go wrong for. especially so if running a 24/7 farm.
thanks for the reminder to focus on quality.
anyone got any idea how long a decent server psu (delta/hp etc) can last ?

Buying noname brand PSUs has always been a bad thing and will always be a bad thing until someone comes up with proof the PSU works. Stick with server PSUs with BBS and trusted brandnames for PSUs. A bad one could mean a dead miner.
I wouldnt risk buying that from alibaba as they can fake alot of items there.
Quality is important here.

thank you Rabinovitch
i was looking to connect it to S9 but i guess the challenge would be looking for the break-out boards....for this particular model...thanks for responding anyhow.

I use AHF-2DC-2100W PSUs with my S9s. It's cheap (if you're in USA), it's powerful, and it looks to be reliable (I used PSUs of this model with Alcheminers). I also use 2 of such PSUs in GPU rigs.
or can i ask - apart from Bitmain - where do you source for your PSU from ? 
i have been sourcing for PSU for S9.
i had bought 3 PSU Delta 2400w (with breakout board) from Paralellminer/Centrix. Very high quality product however they cost about USD109 (exc courier) / USD140 each (including courier).
very happy with these products except for the price.

i had been browsing through Alibaba and they seem to have dedicated Antminer S7/S9 PSU. Approximately USD88 each (exclude transport). One company in particular seems to have a PSU division for mining !
