if you buy this
the 6 jacks are fused at 15 amps.  so 6 x 1.9 = 11.4  is safe.

the 2  heavey jacks are fused beyond the ability of the mfj unit.

but I think you could double up  on 2  of the heavy duty jacks


  you can do 8 for sure..


with the mfj unit

my guess is 10 would be okay.

1 fan each on the heavy duty jacks = 3.8
6 fans on the six lite duty jacks =  11.4

8 and 15.2    each jack single duty.

put 2 more on the heavy duty is adding 3.8

total of 19 amps






use these  to hook up to the tenma

Wow awesome, 24 amps. Do you think I could connect like 10 fans then? They only use 1.9 amps each

How exactly was it a double pay day? my returns are about the same every day  What pool are you using?

yes  here is a beast

will do 24 amps non-stop

Phil, just trying to be helpful to others, but if you delete, I understand

Anyone have good recommendation for a fan controller for this type of fan? http://orionfans.com/products/dc-fans/item/od254.html

I have the OD254AP-12M (12v) one. Want to be able to turn it down a little

Selling Amd 470 and 480 and holding the btc is a good move.

Or cashing 1/2 the btc and holding 1/2 cash 1/2 btc

I've been out of the gpu mining loop for a couple months or so.. Is now a good time to sell amd gpus (470s, 480s) for nvidia (1080ti or w/e 1070)? still dual mining eth+dcr

How bout this blast from the Litecoin mining days ?

A true steampunk masterpiece of engineering:

bought for 20$, running 4 1060s

Old time favorite from ten years ago:
https://www.gigabyte.com/Motherboard/GA-EP45-UD3R-rev-11#ov
bought for 20$, running 4 1060s

They even did not need pin shorting
Working like a charm.

Third rig is running on my former Sandy Bridge desktop MB
https://www.msi.com/Motherboard/Z77AGD65.html#hero-specification
I just cant seem to get 7th card working, I get stuck in BIOS initializing CPU
Any help welcome!

Also, for really cheap mining solution, a truly plug-and-mine MB for up to 5 gpus:

https://www.gigabyte.com/Motherboard/GA-970A-UD3P-rev-2x#ov 
running on brand new AthlonII dual core for 5$ from Aliexpress.

It took me 20 attempts to guess how they had my mailing address on file. I finally had to spell out the house number. Really? What a great process you have there....

I do the same on two of my three rigs. Buy a cheap old HP desktop with 4 /slots.

1) some fancy motherboard that has 6 slots for cards - running 6 rx 480
2) HP z400 off newegg with windows 10 for $180 . Running 4 rx 570
3) HP z400 off eBay for $80 , windows license from softwareswap for $20. Running 4x rx 470s

Biggest problem I had with them was just getting a photo of my ID they would accept. Took too many tries even after getting a new ID. Easily took over 20 times and multiple emails with support to finally get it straight. Very frustrating. But that was the only problem I have had.

I go a different route, i use refurbished dell/hp computers so far that i pick up between $100-150 and use risers to run 4 x 1080ti's off dual server PSU's that cost me $120 for a pair with breakout boards

Has anyone had issues with Coinbase in the past? im really frustrated with them, im locked out of my account because i broke my cell phone that had the google authenticator on, i did the steps to recover my account and got a email saying the process takes between 24-48hrs... that was last Monday...

 Almost any motherboard with 3 x 16-bit PCI-E slots will work, as they pretty much all have the same spacing.

 I used to use the ASRock FM2A88X Extreme6+ as my go-to MB for 3-card no riser rigs (using either a Gigabyte ITX-type card in the "outside" slot, or a Zotac shortie in one rig), but have switched to the ASRock 970 Extreme4 as my current go-to board as I'm moving away from "mixed" rigs.

 For the same "new" price range most folks pay for an Intel dual-core low end Pentium G-series, I can get a quad-core AMD FM2-based APU, or a 6-core AMD AM3+ based CPU which gives me enough CPU horsepower to mine BURST on the same machine I'm GPU mining on - but I'm usually SAVING significantly on the motherboard.
 On used stuff, you can usually find AMD X-series dual-core CPUs or the Sempron 145 REAL cheap for an AM3/AM3+ motherboard - they're plenty to run a dedicated mining rig on.

 DDR4 pricing is getting down to similar range as DDR3, and everything else would be the same identical parts.

 Phil is going way overkill for a pure-mining rig on that I5 - but I used to go overkill on my APU-based rigs so the GPU side of them could work the Distributed.Net project via BOINC's MooWrapper project.

 I prefer the Seasonic X-850 or EVGA G2 850 for a power supply over Phil's Rosewill unit - and I generally can wait to get them on sale from NewEgg at $129 or less (I've got a couple bigger Seasonic/EVGA units as "floaters" I can use to run a rig on temporarily while it waits on it's REAL PS to arrive, and sometimes I'll buy a spare or two ahead of time on the better sales).

 X-850 handles 3 x 1080 OK on a rig where the cards are at 100% TDP (that's the one with the Zotac shorty, it also has a pair of Gigabyte winforce cards with a 200 watt TDP).
 A dual 1080ti single short 1080 rig would probably want a little more PS though for reliability, probably a X-1050 or G2 1000.

 True without question for the 1080ti and 1080.

 NOT true for the 1070 all of the time, though usually valid if you're mining a small-cap coin that's noticeably more profitable than ZEC.

 Not sure on the 1060, but I suspect it's in the same boat with the 1070.

I will give links  and as we know gpus are sky high.

the savings are in the psu it does up to 4 cards  139 for 850 watts and has 5 year warranty

also save on  risers.

and save on   hdds/windows   use usb sticks and nvoc or smos

see build photos

as a three card no riser rig



as a five card rig  with risers

Can you link the motherboard you use to do this? I'm curious how you make this economical.

I mine riser free three card rigs.

Sell them   at a small markup say 10%   I will escrow them for you.  use the marketplace here.

I agree. I hope that status quo is still an option. There's strong evidence that the congestion a few weeks ago was mostly spam, helping to create the narrative that we need to act now.

If the block size is doubled, and they're not full because there are not enough transactions, the latency to validate and propagate blocks hurts the network.

Edit: I went and read the article.  That shows that SegWit2x is not ready for prime time.  This sort of thing is bound to happen when the core devs are shut out of the coding and testing process, and the large miners get less experienced developers to implement their will.
