If you're looking for another alternative, I offer IBM 2880W PSU's with breakout boards and cables, they are being used to power 2x S9's or S7's without any drama. Plus, if you ever do develop PSU problems, the boards and cables are re-useable. Shipping PSU's to you from North America would be very expensive, but if you can find a cheap supply of the IBM 2880's (model AA23920L) in your area, send me a PM and we can work out pricing on boards and cables. I have supplied many mines and data centres with PSU's that are plug & play (unlike some server PSU's that require modification), my customers have been very pleased with the product.

Good luck

Hey Finksy, that looks like a very good alternative. Was actually looking at a 1600W PSU for 300USD, with 5 years local warranty. Hard decision for me. I'm actually leaning towards 5 years local warranty, due to the reason that i'm not sure whether PSUs breakdown easily, and their usual life span after being used. What do you think?

Hi MiningRonnie.

Looks like the Server PSU's are expensive in your part of the world.
I just ordered two more for £19.00 the pair from eBay with free shipping!

If you get stuck I can see if I can source in the UK and ship over to you, just a thought.

Hey buddy, thanks for the great offer! I'll actually consider that. What PSU are you actually talking about for 19pounds a pair?

The APW3 vs other non-bitmain PSU debate is something I've been mulling over. As of right now i've got 4 APW3's working great, all are putting out 12.23~ volts. I've ordered a 2000 watt IBM blade center PSU ($30 refurb) and a breakout board kit with cables from holybitcoin. Costs me $60 less than ordering APW3 from china, I'll report back my findings once everything comes in Grin

Great! Will be waiting for your findings then. Which PSU to use is actually a big decision for me Undecided

Never had issues with bitmain's PSU.... running 408v 3 phase 220v single phase... all connections running stable on all miners... then again we do have power factor correction and stable voltage 24x7x365...

Did a google search on power factor correction. Is that something that helps on saving electricity? Do you mind explaining how it works? Thank you!

I have not had any issue's with APW3's. They are what Bitmain recommends with S7/S9. I personally have followed this and not had any issues on the PSU side. They have kept working for quite a while now on some as I sold S7's and kept the APW3's. They can power even the batch 1 S9's which had the highest hashrate's.

There will always be market of server PSU's with breakout boards out there. But until I have a problem I will keep using APW3's as far as S9's at this point. I am not knocking some of kit's out there as I have not tested them. So just making clear not knocking them just saying what has worked good for me.

At this point a lot of my ATX psu's I had laying around from previous gen miner's went to mining Ether. I have had a decent variety of PSU's over the year's. If you have the 205V+ it is the one I would go for. If under the 205V then I would look at the EVGA Supernova 1600 you mention, as EVGA does have some great highend PSU's.

Thanks for your input. Can i ask how long have you been using those APW3s? The reason why im afraid to use APW3s is because i'm afraid that it would breakdown after the warranty expires.

I actually have 240V over here. I'm actually leaning towards APW3s now after hearing your input. Decisions...
