Mining Rig review is needed

[mindrust]

I am about to put together a hybrid GPU&HDD&CPU mining rig.

Bought these already:

x1 Corsair Vengeance DDR4 2400mhz 8gb- $120
x1 Intel Pentium G4400 3.3GHz 3Mb- $60 *** Got an Intel i5 6402p on my other PC, might use it as well for CPU mining.  
x1 Intel Pentium G4600- $85
x3 Seagate Backup Plus 8tb External USB3.0 HDD- $200/piece
x1 Gigabyte GA-H110-D3A Intel 1151Pin DDR4 Vga USb3.0  Motherboard- $125
x1 EVGA Nvidia Gtx 1070 GPU- $850
x1 HighPower 80+ 700w PSU- $75 *Not going to use this, will keep as a backup or maybe will do another rig*
x1 Cooler Master V1200 80PLUS PLATINUM PSU- $338
x1 M.2 128gb SSD- $60
X5 Arctic F12 Cooling Fan -v$35
x1 Wattmeter- $19
x6 7th Gen Risers- $8/piece
x1 Homemade 6GPU Rig Cage- $10
x1 Linux Ubuntu or Win10- Free
-----------------
Total Spent: $1890 $1905 $2365.

My thoughts;

I'll probably end up with 7- 8tb HDD's. Since they all got their own adapter. No problems here.

I bought the 6 slot mobo because i though i might wanna extend my rig to 6GPUs in the future so mobo is OK for its price too. I lost around $60 for not going with the cheaper 3PCI-e one here. Ram and CPU are ok too, i'll probably use my other i5 CPU because it's a better monero miner.

Bought only 1 GPU. I didn't want to gather 6 1080ti's  all at once because It would be a stupid thing to do since I am a newbie miner.

And From what i see, gtx1070 is one of the most efficient GPU's out there. (I probably overpaid for it but trust me that's the best price for a nVidia gtx 1070 in where i live. So price of the GPU is not questionable.) It mines many algos, it can be underclocked, overclocked whatever. So started with buying one of these. I also know that nvidia is about to release 20xx series miners (I mean GPU's xd) soon so I don't want to over invest in outdated GPU's.

I'll probably go with win10 since I want to mine Burst with my HDD's while I mine using Nicehash with my GPU. Might try Ubuntu if i get bad results.

What i'm not comfortable with is the PSU. It is super cheap for its price and the manual says its %80+ efficient under %50 load. Since I own only 1 gpu for now, I believe I'll benefit from that feature. But, if I decide to get another one, would it create a problem? Should I send it back and go for a bigger&better one (like 80+ gold PSU) so I can be ready for the upcoming GPU's like my mobo did? Or Should I just add another 1000w PSU and go with 2 different PSU's when I decide to add more GPU's? I can't decide on that one. Since It looks good for its price I want to keep it but still can't decide.
*Dumping away the HighPower, got myself a Cooler Master.
Help me out!

Is there a reason you are buying 2400 MHz DDR4 when you're CPU only supports 2133 MHz? You also need to upgrade your PSU, that POS PSU running under load 24/7 is not going to be up to the task. An EVGA G2 850 W for ~$150 would give you enough wattage and connections for up to 6 1060's.

I don't know why people have no problem overpaying by hundreds of USD for GPU's, but yet try to save a few bucks buying a POS PSU when the PSU is the most important component in your rig. If you're PSU goes out at best you're whole rig is down and at worst it can damage components.

Probably missed this one. Didn't know CPU's had issues with Ram compatibility. Both Pentium and i5 support 2133Mhz? Anyway that's not a big fuck up. Ram will work at 2133Mhz mode then.

I think the question is suggesting you could get cheaper RAM if it was 2133 instead of 2400 since 2133 is as fast as it will run anyway.

Ah I see, I wanted it to be faster. Let's just say I couldn't resist.

That would depend on the motherboard if it can down clock the RAM to run at 2133 MHz. Typically the faster memory speeds are only supported by the higher end processors, like the i3-i7. Buying faster RAM than you're CPU supports can cause compatibility issues.

I see both them are supporting only 2133Mhz. I guess I'll need to send Corsair back.

[mindrust]

Wew you saved from a lot of trouble. I read that thread. I really do have to send the ram back.

[mindrust]

Decided to send CPU back instead. Gonna get G4600. I see that one supports 2400mhz.

I didn't have high hopes for CPU mining anyway.

I would advise as well to take a better PSU. Will save you on energy costs.

I just ran a few simulations here with Overclocked Nvidia gtx1070's and the I see the difference is minimal between a 80+ PSU and a 80+ Gold rated one. It is around %6/year (€20/y) which is not that much as long as I run only 2 GPU's.

That means It won't make much of a difference if I ever send this back and get a Gold rated 750w. So I'll keep it and buy another PSU if decide to extend my rig further.

(*kwh cost is set to 0.10€)

A better PSU isn't just about efficiency.  Higher quality PSU's have better load regulation and can increase the longevity of the components it's powering.  Never skimp on PSU.

[J4CKT]

Not only is a higher 80+ rating cheaper to run they also generally come with longer warranties as they use better components.

The other thing to look at is how many PCIe power connections are coming with that PSU as that will dictate how many gpu's you can power with it.

It is not only about efficiency , as you can see the gold come with more years warranty that should give you a hint , if you are building a gaming PC I wouldn't mind , but a mining PC which will run 24/7 is totally different thing . Also I would recommend to go with Evga , seasonic or corsair 80+ Gold .

Evga 750w G3 $110 on amazon  .  You will pay $35 more but trust me will totally worth it .  Never try to save money on the power supply .

I do not think that these components op got are very cheap. I can get the same card for 670 usd and something. 2x PCIe would be most of the people choice to have the connection from the board to cards.

I suggest 1700W Corsair SMPS for having around 10 cards on the one time. If you buy 1000W one or lower than that you will be able to get the maximum number of 6 cards on that SMPS. Mining components dedicated to mining will be always give around 3 months to 6 months warranty but regular cards will long time warranty.

Started mining with 1 gpu. Gains are super low. Makes no sense to expand my rig while GPU prices stay same but profits go down.

Will buy some new nvidia gpus instantly as soon as they arrive though. Can't afford to make the same mistake twice.

the psu is garbage 2 cables so you can do 2 1070's

 max power  is not 700 it is 630watts.

so when you run 2 1070's be sure to keep the tdp set to 80% or less.

Let us know how long the psu lasts.

My guess is not very long.

Thanks for the response. It is nice to hear an advice from a pro miner.

Yes now I am aware of my mistake that I did with PSU but no big deal It was too cheap. I'll keep it as a back-up after I buy 5 other GPU's (probably they will be gtx2070's) and a 1200W Cooler Master PSU.

For now I'll leave it as is. My current OC numbers are 70%TDP, +150/+500 drawing 150W. Equihash hashrate is around 443H/s. Making 2 bucks a day. Sad days.

[mindrust]

Just bought Cooler Master V1200 God dammit. I'm ruined. What Imma Gonna DO!

Now I'm sitting on 2 PSU's. Have to find a buyer for the shitty one.
