I might actually buy this at some point and hook up 3 cards for a dedicated mining build. Anyone foresee any problems mining with such old hardware? Had fun anyways window shopping for these parts. As for the PSU, there might be some debate that it is not high enough wattage, but I think it is plenty going the Nvidia with 70% power limit

inb4 hate for stealing all the gamers' graphics cards

[Himommies]

Wound't this build be very inefficient electricity wise

[RadiatingLight]

I think that the older CPU and platform, while they might save you a few bucks now, might be a bad choice.

the older CPU will consume much more power, and I think that overall a slightly more expensive platform will be better.

 

also, why a 550W PSU.

usually, miners want the most efficient, most high-wattage PSU they can get. 550W is enough for a single-GPU system, but not for a mining rig.

Well, no mining build is really energy efficient at all.

I don't get it.

Can your use proper English?

Didn't think of that, only two things that add usage are CPU and HDD, You can buy 16gb SSDs for $10 to solve that problem. Now that you got me thinking about, it might be worth spending that extra $5 to save 30 or so watts. As for the CPU, it has a low TDP might be the same usage as modern cpus even though it will have to work harder at idle.

Can you? That's a perfectly coherent sentence.

[ProjectBox153]

It's not worth it to buy all that. You can get free Dell OptiPlex systems from the late Core 2 Duo to early Core i era for free these days, and they'd be a lot better. Free system, so your money is spent on a GPU, not all these old (and frankly rubbish) parts.

FYI, You are going to need more than a 550w PSU for 3 graphics cards. Peak use will overwhelm that PSU in short order.

 

[PipWinsAgain]

I did some newegg shopping and I can build a machine with double the PCI slots for a little over double the price. Savings in power would quickly make it cheaper and It would be more realiable hardware. 

 

It was fun looking anyways. I was amazed at $4 dual core amd cpus.

Agree, even with fine tuning the cards for best performance to watt ratio.  The cards are still going to consume some watts.  Biggest thing, what are the three GPUs in question?  Depending on GPU will vary the power draw.  I have four GTX1070s that are tuned depending on usage (three profiles for Folding, BOINCing, and mining).  Even when mining at 65% power draw restriction, the cards still pull some decent watts.

In my head, I was thinking 3 1070s at 70% power limit. 

 

Ive decided against going against the cheap route and now I want to build  6 GPU machines. I want to keep adding more machines until mining profit becomes less than $1.50 a day on GTX 1080ti or $1 a day on a 1070. (not sure what gpus I want to use, but its between those two right now) Going to put them in a garage

 

Im about to leave home for work for about a month so in the meantime, im going to mine with a few gaming gpus I got laying around on my gaming PC. Im going to get into this slowly and see what happens. 

 

What i have going for me:

8.5 cents per kwh peak rate

Cold climate for 8 months of year. Wont have to worry about putting AC/insulation in until late May of 18

Doing this for fun and not for money.

 

This kind of project is something that I think I would really enjoy. Breaking even  would just be icing on the cake.

Here is what I currently have planned for a 6 GPU 1080ti build.

4gb cheap ram

32gb cheap m2 ssd

2x Seasonic  850w gold PSU. They are fully modular because I want them to have some resale value and Im bad at cable management

ASRock H81 PRO BTC LGA1150 or BIOSTAR TB250-BTC LGA 1151. I like the ASRock board better, but it is lga 1150.

Leaning torwards GTX 1080ti for GPUs

Intel G3930 if I go with 1151

 

Edit: probably going with 1151. Lowest end 1150 CPU is actually more money USED than it was on release. I wonder why that is.

[Ithanul]

Darn, 8.5 cents.  Wish my electric bill was that, stuck with 14 cents per kwh.  Then again, I am the nutty who was running two OCed BIOS modded GTX980Tis 24/7 for folding/BOINC.     Power bill...pffff.

 

Probably the best thing to do is research the good spot for power draw on the Tis.  Still, darn six of those?  Be sweet to see the folding and BOINC output of such a setup when it is not mining.

I really wanted to build a 2 or 3 GPU folding PC before the bitcoin craze but realizing the cost of electricity stopped me. Alt-coins allow me to at least pay for the electricity and possibly more. I will continue mining if profitably drops below $1 per GPU, just wouldn't add hardware

[foldinghomealone]

You're lucky. In Germany usually it's around 30 cents (US) per kWh and higher.
