ran into a strange problem with a test setup I tried - a few 280x with these kind of externders connected to Z750p with the 6pin pci-e and to a regular PSU on the molex side. They did not turn on when I started the computer.

It's likely going to be a higher quality of power than you'll get from any ATX supply (of comparable power output) that you paid less than about $120 for. The only real concerns are the quality of a hokey wiring job.

are server supplies good for GPU use? I want to make sure its safe to do before i go wiring a hokey DPS-800GB into a valuable GPU rig

On GPUs, only 2 of the pins are used for 12V power so that's 18A per connector. But on GPUs only 75W comes in per 6-pin, which is only 3.1A per pin. If you adapt 6 pin to 8 pin, you use all 3 lines but for 150W, so 4.2A per pin.
Standalone devices like Cubes and Ants, which can pull in 360W per device through two 6-pins, if using all 3 lines, pull 5A per pin.
And just because 20AWG is rated for 11A doesn't mean it's a good idea. Every experimental result posted in this forum will tell you the wires get uncomfortably warm.

Yeah guys, that is correct. But do you know that your molex cripms are certified only for 9A@each crimp?
Also 20AWG is certified for max 11A (means 30-33A per lead, that is eqaul to ~360W). Sure this is theory, but certified values are higher anyway.
source of statment, that crimp is certified for 9A:

I've got an overclocked Ant and an overclocked Cube running off some 12" 20AWG PCIe cables, and they do get warm. Any longer and I'd throw them out, but it's what I had available at the time. Everything now runs off the 16AWG 18" cables with zero issues at all.

Hey!
I'm reading this topic almost since begginig of it.
I have bought DPS-1200BB, which will be used for GPU mining. I assume you all are talking about ASIC mining here, correct?
After reading your debate i got confused about wiring. Does ASIC miners need more current then GPU? Because 8pin connectors with wires that i bought got 3x 20AWG (cables are 30cm long (12inches)...
Is this enough?

The boards sold here to work with the server PSUs could be used for either GPU or ASIC mining. I believe its a toss up in terms of which draws more power GPU/ASIC due to the hacks and overclocking mods now on some ASICS that allow for more power/performance use.
If you are considering GPU mining I would suggest that you have at a minimum 18AWG wire in runs of less than 2ft. From my understanding the cables sold here are 14 or 16AWG which yields more safety headroom.
20AWG cables are unsafe - you should not attempt to run more than 200W through a single 20AWG PCI-e lead, even then they will get warm.
18AWG will be safe for closer to 250-300W
16AWG is what you should use for high-end GPUs, can safely run 300W through a 6/8-pin PCI-e

I actually will be sourcing a number of supplies in a bulk purchase, so I'll be able to sell complete "kits" with the supply, board and four cables.
Also glad everything arrived and is tested and approved.

Wow that would be a great option for some. Especially for people only needing a couple as the price of the small quantity Z750P buying options begins to increase.
It would really be a complete kit then. Good luck!

Just wanted to post my own experience with sidehack.
He shipped waaaaaay ahead of schedule. I paid on Saturday the 8th with full knowledge that the cables would likely cause a delay in shipping until the 13th or 14th. The package arrived on the 12th! I wasn't even in town at the time. But damn dude that's some excellent customer service!
The boards themselves are very good production value wise. Interface between the board and the power supply is solid. Screw terminals were a great thought. Excellent documentation included! The cables are well made and reasonably priced. Blade ends fit snugly into the screw terminals. Very little play, which is an added bonus in my mind. They are a good length for the average user.
Don't hesitate to order from sidehack if this board fits your needs. If you can source Z750P supplies cheaply enough you're getting a very decent end result for great price efficiency.

Possibly next week. Got a fair bit of stuff to coordinate first, and we won't get any work done this weekend on account of an out-of-town wedding hooray.
February 19, 2014, 12:25:35 AM
Not really, at present. How many would you need? When sales open, boards and cables will be sold as separate units so you can buy one, the other, or both.
When are you going to open sales again? I got a few Z750P's sitting around awaiting for your boards

Trash, not single rail
Thanks !!! Theres a lot of these kind of PSU's on ebay,dang it...............Most need a board like sidehacks though
If I win Lotto tonite,I'll fund some board designs
Yeah...right,like anyone wins Lotto If you win, you buy us all psu
I'll buy one of those pallets above of PSU's & do a giveaway..how's that

DPS-1520 ftw!
1440W per psu is awesome. I have two of these here, and would love the interface kit for them...
Would be able to run my cards no problem with these two!
