Hoi!

What temperature is that warm environment?

I can give it 10c, or just put it in a shed where is ~0c

Groetjes,
mav
warm i mean 30+
One customers has them running at 20c and sometimes they fail... (dunno frequency/ precise temps)
I can make a version with 10 connectors, but I cannot guarantee it will be able to pull a S7 all by itself...

regards

Why do they fail? Cuz your customer tries to pull over 1300 watt??

It would also be nice a to see a efficiency curve because highest efficiency is usually only available at 50% load.

1300 watt not on stock anymore.

I'm working on a cheaper board for the 2880w IBM PSU as wel as a smaller PSU (1300w+)

At the moment I only have the 1440watts on stock.

About efficiency, I just bought this baby: https://www.elektor.com/voltcraft-digital-clamp-multimeter-vc-330
This week I will be measuring effciencies of the smaller PSU's

Why Bitcoin +1%?
I buy the PSU's & cables in euro.

there are 2 reasons the price is +1%
- btc/eur rate is volatile, so it covers some of the risk
- conversion isn't free (usually a percentage of the amount)

I recently bought a set of 1440w power supplies for the increasing power need of the S7.

Unfortunately, the PSU's refuse to deliver more than 1200w for a longer period of time in a warm environment.
So I'm now selling them as 1000w power supplies. 1 can run 1,5 S5 | 2/3rd of S7 | 3/4th  of a avalon.
Each PSU comes with 8x PCI-e, so you can easily connect 2x S7 on 3 PSU's

prices
1+: €55
3+: €50
10+ €45

EU shipping/escrow welcome

I'm looking for someone with an S7 to test how well the 1300w runs it.

I'll give a nice discount for a small review
(and if it doesn't work well I'll take the unit back, on my cost  Smiley)


stock

1300W IBM  8 1
900W Dell 03 0

looks good to me too, also the 16awg is a good choice!

how is the noise with that fan?

I made a short video of the miner with a Monarch connected (400w)

The phone has noise anceling I think since there is more noise than you can hear in the video...
https://youtu.be/XE-TaWR3uQQ

I think noise level is around an S3, maybe slightly more. A lot lower than an S5 or the DPS-1200
