We are sold out of the power supplies but still have plenty of boards in-stock.

Pin 35 (Top) is the 5v you want. Don't use 29 that is a digital logic signal not a power rail as far as I can tell.
Thanks for the heads-up on that.
Makes it even easier to solder a cable to as it's right there on top.
Seconds.
Thank you.

Cool, this might help, the 5v points are circled in Yellow and the 3.3v points are circled in purple. The vias can fit size 24 AWG wire and you can get a breakout for a USB socket for a few bucks from Sparkfun.com
I already have enough sacrificial USB cables to add a charging point.
According to the pinout I have, pin 35 (top) and pin 29 (bottom) are both 5VDC.
I'll check them with a meter first but will only take a couple of minutes to solder on a USB socket.

nice low cost choice for power.
the 1300 watt evga would run 3 and save as it does 1215 watts for 3 units at 393 cost of 195 usd
But if you run 2 units this costs under 60.
So in order to do a proper comparison
you need 6 ants 2 evga's or 3 of these.
2 evga's = 390 usd
3 of these = 165 usd that is 225 difference
both will run six ant's
power on the evga = 2430
power on these = 6 x 465 = 2790 so that is 360 in watts x 24 = 8.5 kwatts a day at 20 cent 1.70 a day
so after about 132 days you are tied.. and if you only have 2 ants the time difference is more in favor of these.
1 of these 60 bucks 1 evga = 195
135 usd difference power is 930 vs 810 2.9 k-watts a day at 20 cents is 58 cents a day or 232 days
so for a small miner these are pretty good.

I found the pinout, so I'll probably mod this to add a USB +5VDC connection because not only am I using one of these to power my S1 but the design of your board is so nice and the power supply so good, that I will be using one as a bench test power supply and having a good +5VDC supply to keep small MP3 players charged, or a phone charged, will be handy.
I do car stereo work and sometimes you have to bench test things but amps require a minimum of 30A when they get up into the higher power range. Accessories that use USB (like the little Sansa MP3 player I use) need 5V to at least keep the batteries charged, so tapping into those pins will be good.

I notice that the supply can also provide +5VDC @ 2A.
Have you thought about putting a USB connector on the board to provide power for things like a Raspberry Pi?
Yeah, when I was initially designing this I was doing it for my own purposes and was thinking it would be silly to power the Pi off the same supply since if the power went out then you wouldn't have a way to know since the Pi would loose power too. Sort of realized after the fact though that there were a lot of different ways people would use these and probably should have put a 5th pin on the header for 5v power and offered a USB socket add-on board you could pop on the header.Have you thought about putting a USB connector on the board to provide power for things like a Raspberry Pi?
If you have a soldering iron you can actually mod the board to add a USB power socket w/o too much trouble.

This adapter is so beautiful, I have thought about looking for factory customization, but eventually gave up.
It's so nice that I just bought another one and another power supply to use to bench test car amplifiers.

What are the dimensions and spacing of the two mounting holes?
The mounting hole are spaced 70 mm (7 cm) apart on center. The holes are sized to fit a M3 machine screw. The power supply also has holes for machine screws in the bottom that fit size M3 screws. Their spacing is also roughly 70 mm +/- a few mm

We are expecting a shipment early this week and should have more ready to ship by this Tuesday. Will update here and on the site when we are back in stock.
Edit: When we are back in stock the first 30 orders to use the coupon code "BITCOINTALK" will get 8% off any number of Gigampz boards at checkout.
well thanks for the item with the discount..got 1 unit...free shipping and 8% off of 40 bucks using bitcointalk in coupon box..can't beat that ....(don't really need it yet..heh..but eventually)

We are back in stock, We also have a new version of the power supply that is a couple bucks cheaper but this one runs a little hotter.
