As an aside it's a bad idea to use plastic that doesn't meet 94V- standards like you are since if you have an over heating incident you are more likely to have a serious fire instead of just some melted plastic.
Not sure if that was in specific reference to the images I posted, but if it is, I can not think how you came to the conclusion as to the standards it meets / complies with. I did (after your post) look up the details on the perspex material I am using and I have no concerns whatsoever in that regard. I mean using it in the manner you are sandwiching components that are going to get warm if they are over loaded. Not that the particular plastic you are using is or isn't 94V-0 or better rated. 94V is a fire retardant spec for those following along. |

I can tell by looking that it won't work on the 750W, at least not the ones I carry.
What's the part number for the Dell 750W PSU's connector if you care to share? I'd like to build them for the dps 2000bb but at 2000watts, I feel a need to find a larger terminal block to effectively build them. They make larger terminal blocks like 65 Amp and 125 Amp but no distributors stock them so there are 6-8 week lead times and minimum orders of 1000+ pieces. This is all a fun creative exercise but I really don't get the point beyond that. You are still buying the two most expensive parts of any adapter board; the mating connector and the terminal blocks. Once you figure in your labor costs these things probably cost twice as much as just buying an adapter board from any of the several establish supplies. As an aside it's a bad idea to use plastic that doesn't meet 94V- standards like you are since if you have an over heating incident you are more likely to have a serious fire instead of just some melted plastic. |

I have stock of 30 amp 2 pos 7.62mm screw terminals I can sell you. I use them in some of the Gigampz breakout boards I build. They have little channels on the side so you can join them together to be any length you need as long as it is a multiple of two.  Help me out. 2000 or say 2200 watts at 12v DC Push 180 amps give or take four of those can't handle that? Trying to find a heavy duty lug, but not much luck No way, they are rated for 30 Amps each you want a bare minimum of 6 (180 / 30 = 6) |

What is the noise level of a DPS-800GBA and DPS-1200FBA?
Is louder than 40DB? Is it louder than a Antminer C1?
Depends on the load, and the ambient temps since the fans are controlled by a temp sensor. I don't have an easy way to measure the db level. At max load they can be fairly loud. If noise is a concern I've found the Platinum version of the DPS-1200 is pretty quite compared to the stock DPS-1200FBA. |

I'd be interested in these depending on the overall cost (including shipping to UK). What'd be the price + shipping for a lot of 30 2 poles? I can do 15% cheaper than the digikey list prices. So for 30 $1.05 ea. Shipping to the UK might kill that savings though it would be a 6 oz package which would be $12.18 for First Class Mail. Shipping to the US would be much less. These prices assume payment in BTC. I can also do Paypal but there are additional fees of 30 cents + 3% for that. |
