Title: Dell 750 W PSU Questions
Post by: olliec420 on July 22, 2015, 08:02:37 PM
Hi All,

I have 2 dell z750 PSUs and adapters (i forget what make they are, see pic).  I am going to be running a couple S3s off them (with plans to step up to S5s).  For those of you that have done this; can I run two S3s off each one of these?  Use 16 or 18 AWG cables?  Could I connect two sets of cables to each one or am I asking for trouble doing that?  Recommendations where to get such cables?  Am I missing anything?

If you do not OC (in fact I'd say you need to underclock a bit) then you can run 2 S3's on one of these.
With regard to cables, I'd go for 16AWG.

Looks like gigampz adapters. Two S3 will run fine off the Dell 750W; expected power draw is about 700WDC (at stock speeds) and these supplies are typically capable of at least 800W. Depending how many cables you were using, 16AWG (for two cables per S3) or 18AWG (for four cables per S3) is good.

The manufacturer of those breakout boards (pmorici) supplies cables with them. Ask him for specific info and purchasing.

Yes gigampz, I've had them for a while i forgot.  I will holler at him about cables thanks.

I do not OC, i run stock.  I think i'll run with 2 cables to each miner at 16 awg.

Thanks guys!
