Just received the first batch of APW5 PSUs and R4s. I was a little uncertain about the actual number of 6-pin PCI-e connectors it came with due to some of the images showing only 7 connectors total. I'm pleased to share that there are indeed 14 x 6-pin PCI-e connectors, as originally advertised by Bitmain. The APW5 does appear to be capable of supporting 2 R4s with a single PSU (using 220v power).

What does the label on the side say for efficiency? 91% 94% and platinum or what? make model of psu maker ...all that kinda stuff

curious could not seem to find such on the info stuff online

Got mine running. I am impressed with the noise, VERY acceptable. It's the sound of a small level of a small desk fan. Now I just need to see if the heat is acceptable.

After 12m, miner is reporting avg hash rate of 8565 Gh. Nicehash is reporting an accepted rate of 10.2Th (!) reporting a payout of $6.3/day.

After 35m, miner reporting 8691 Gh, Nicehash reporting 9.5 but bouncing around.

Well what is the guess for BTC difficulty for the next year it takes to ROI...is it gonna be 'flat' due the the halving or nuts as usual..if it is flat you could do ok with a 1 year
ROI on this beast

comments anyone on above? Is that the plan for those getting an R4 (that and a hopeful price pump of BTC)....

id expect to see at least a 50% increase in hashrate over the span of the year, probably closer to 70-80% (assuming fairly stable price and no major changes in hardware prices). thats about 2-2.5% increase per difficulty period

considering the miner makes ~$5/day, minus ~$2/day if you pay ~$0.08usd/kwh, you're looking at an ROI of more than 18 months probably. if power is "free", more like 10-12 months.

Well was kinda wondering...IF and I mean IF the difficulty was to have been more FLAT (like LTC difficulty the last 2 years or so) THEN a case could be made for these units

with a 12 month ROI to climb out of the hole (with maybe a BTC price pump) at 10-12 months and then just chug like my knc titan scrypt miners did for that extra year or so

Was naive....to think so...but thought maybe with BTC halving a mining glut and investment into new BTC equip would cause some kinda lag (if you can call 50% growth of BTC

difficulty a lag)

Anyway such a game still may work out for those folk with 3-4c kwh usd electric ...me at 14c kwh Summer rates (5 months) and 10c kwh Winter rates.....that boat don't float

for a BTC miner at the 1300 buck price.....so I guess will stick to scrypt mining and convert LTC to BTC (only 10% in LTC) and continue the sideways method to BTC via home

mining. Only thing that works. (Also it heated 85% of my house last year at 3000 watts ...figure now I have 6000 watts I'm golden again this year)

angles ..always crypto with the angles
