philipma1957,

Any idea on the efficiency of the power supplies? I'm kind of wondering if we cant' drive these using a more efficient PC or server PSU with a breakout board.

Here's a fun graph, my power consumption on 3 units over the last 3 days.

This kind of makes me wonder if these can't run using 70-80 watts with the right PSU and winter temperatures.

I also got some of these in marcotheminer's group buy.

Yeah I have been looking at a dozen oem websites that sell 12volt 15 amp bricks.

That is the brick size we get.

After careful study the worst brick I found had 78% efficiency and the best brick I found has 88%

So if you put in a 95% titanium vs 78% the 111 watts would go to maybe 91 watts best case

but if it is the 88% then the 111 goes to 102 watts

If I can determine that these are 78% bricks I will post back with results using a titanium psu.

I think this adapter tip is 5.5 by 2.5 size

I will buy it I have an old grid seed cable

I will connect it to this tip and use a few psu's

do not rush to buy any of the above. I will test and present results by Sat the 24th

this is much like a 1300 watt EVGA gold.

i hooked up a 5.5 by 2.5
dc adapter
https://www.amazon.com/dp/B0915MTZSG?psc=1&ref=ppx_yo2ov_dt_b_product_details

I had an old interface breakout board that let me do this a via screws

the psu was running some gpu's and pulled 490 watts no ipollo

it now pulls 576-592

a range of 86-102 watts

the other one on a brick does 92-109

so it looks like a 88-91 psu gold is a lot better than the brick the brick looks to be around 80 or a bronze

so if you understand how to wire and choose a plat psu you should save 10 watts a unit.

The dc adapter tip is good but needs better wires than what comes with it

Also note this gear does have a power range of 14-17 watts as it pulses the draw.

I suspect if you get a psu like this
https://www.newegg.com/evga-220-t2-0850-x1-850w/p/N82E16817438064?

and wire correctly you could run 4 ipollo at 360 watts vs 420 watts brick

Thanks for the write-up, I might try this. The adapter you bought uses screw terminals, any concerns using these long term? I was originally thinking of soldering wire to a connector.

well the plug is rated for 10amps and 12 volts = 120 watts.

now that the unit is running on the gold leadex psu it has never gone over 102 watts.

it swings from 86 to 102 which should be okay.

I am thinking of finding a titanium as I have a few and see if I drop to 79-95 watts.

I used 16 gauge copper wire with the dc adapter about 2 feet long

Maybe it is 14 but It is at least 16 gauge.
