Where can I get cheap PSU to run miners? I need 1500-1700 watts total.

[apollojmr]

Thank you..I am looking for cheap but yet good psu. I know I have seen dell server psu and things like that but I cannot find them now.

i see there is 3 listings of of the dl580 1300w units on ebay below 20$, just search for "337867-001".
2 of those and you have miles of juice

You can not just plug and play with these can you, wouldn't you have to mod or add something for them to work with most miners?

I'm currently building breakout boards for me to use with this PSU. First prototype will be finished today or tomorrow.
If there is some interest, I can make more and resell them, price should be around 20$ excluding shipping.

I'd probably be interested in a breakout board for this if you have them ready soon.  Do you think it would it be possible to run 2 S1's and a S3 off a single one of these?

I would be interested in 2 if you do produce for sale, can you post a pic once you have first completed?

It will have 8 screw terminals. I'll test it as soon as I have it done, but each screw terminal should be able to handle 150w, probably closer to 180w (15A@12V).

I can prototype quite fast and have a few spare connectors for this PSU, but quantities over 10 will need more time since there is no reseller who have the 51940-038LF connector in stock.

What is actually sticking out of the PSU? Is it tabs that you could just solder to or find a push on connector for ?

Its hard to tell from the few pic's I can find.

Is there a fan in the PSU or does it need provided?

Thanks,

[apollojmr]

I am also interested in buying one of these breakout boards. Let us know what to do and maybe you can hijack this thread to start a GB. Thanks!

Basicly the flat ones are 12v/ground/12v/ground on each side and you connect 3 of the middle pins to turn it on and keep it running.
I do not have any extra cooling on mine.

If you do not feel like soldering directly onto psu, you can buy flat cable shoes (not sure if correct translation) and press them onto the flat metal bits.

That's what I'm using at the moment, 6.35mm ones, but they tend to move out of the tabs.
There are 2 fans inside the PSU, 60mmx38mm, high CFM (loud), similar to the ones sold here:

Back to drilling the prototype board.

Thanks for the answers, crusader, J4bberwock and tvasbn.

That blue female quick disconnect connector is exactly what I was thinking of.

You can squeeze them a little with pliers to adjust tightness if they are too loose.
Make sure you have plenty of spares as it takes a few to learn how much force
to use to "correct" them.

I am also interested in 1 or 2 board's if you get them ready.

Thanks,

So, I see how you would use the quick-disconnects to connect up the positive and negative leads to power the miner. But how would you connect the pins to jump the power supply? without soldering.

i bought a few packs of these female jumper wire from glorius china
so i just cut them in half, put 3 onto the pins in question and tape the leads together with electrical tape.
at 1.5$ for enough connectors to do 25 psus its almost free.

Which three pins? Just 1 from each row tied together?

here is the "how to" for many server PSU, including the HP DL580 G3 that is on the first page.

Finally finished drilling 117 holes.
Now, I know why I do prefer prototyping SMT boards.
Components placed, I'll solder and test tomorrow.
I'll have some pics too.
