Serious Advice required for budget Cryptomining Rig

[Abdurrafay_5679]

Intro

Hi ... I'm 16 and I'm from Pakistan ... I've built like 2 PC's before and I follow a lot of tech tubers on YouTube. When I started my 11th grade, I sold my PC because I was playing cod all the time ... I never really sold my first PC because it had PSU issues and I ended up dumping it out. And I never really take time out to do anything with it

The PC

So the PC or components I have with me right now are

• 
  Core 2 duo e4400 2.0 GHz with kinda broken hsf and some Chinese cheap thermal paste
  2 x 2gb ddr2 667mhz
  Gigabyte ga-smthing motherboard
  A 120 gb sata hdd
  And a really garbage piece of tin case

The Idea

So really the idea here is to build a cheap Cryptomining rig with this beast components .... I just need 2 components : a PSU and a GPU ....
And for Cryptomining that's what all matters .. now in my country the value of our currency is really low next to usd .... 1 usd = 110 ruppees
So if I earn from Cryptomining .. I earn dollars which converted to our currency actually has a lot of value ..
I have seen ads on 2nd hand 750 ti's for as low as like 8000 ruppees which is like 73$ .... And new psu's from online stores like masterwatt lite psu's for 400w = 4500ruppees which is 41$ and 500w of the same = 5300 ruppees which is 48$.

Electricity Costs

Now here electricity costs are a little funky .... But as long as I keep it secret enough ... Dad won't notice it...
And the 750ti draws like what 35watts and it's hashrate to power draw ratio is amazing ... I couldn't make anything out of this sheet but if you're willing. ... Be my guest

The Question

Now I've got at least a year and a half of pure studying ahead of me ... And i won't be gaming for that while. Now the question is ... Will the rig be able to pay itself off in that time frame and would it have some resale value after that time and is this even a good idea ?

No-one can answer you if your mining rig would pay for itself during the 1.5 years you study at the school since there are too many variables and a whole lot of uncertainty.

Variables are the different cryptocurrencies you can choose from to mine and if you can keep your rig running problem free. While the uncertainty is if the cryptocurrency will hold up and continue to grow in value or if the whole cryptocurrency market crashes, leaving to no value for the mined cryptocurrency.

As far as resale value goes, expect it to be 0. Since even at today's standards, GTX 750 Ti is weak and low-end GPU. If the cryptocurrency market crashes, the 2nd hand market will be flooded with cheap RX460, RX470, RX480, GTX 1050, GTX 1050 Ti, GTX 1060, GTX 1070 GPUs, which are far better than the GTX 750 Ti.
Also, the PSU you're planning to go with is low quality to begin with and i don't think you'd find anyone who wants to buy used low quality PSU from you. I wouldn't use a Cooler Master MasterWatt Lite series PSU even if the brand new unit is handed to me free of charge.

If you're willing to take a risk on cryptocurrency to make it big, feel free to do so. But prepare yourself to loose it all when sh*t hits the fan.

@Aceaus Hmm ... So it's a 50-50 bet ? And the only other psu's here are Corsair vs series and thermaltake smart se series which after reading through an extensive article made me choose the masterwatt lite ... Did you encounter problems with one ? ...

I don't need to own a Cooler Master MasterWatt Lite series PSU to know that it is low quality. There are no reviews from reputable sources that would say how good or bad that unit is. And without proper reviews, PSU is usually a bad unit. This, and also the fact that official specs page list this PSU only having 11ms of hold-up time. According to the ATX PSU standard, all PSUs should have at least 16ms of hold-up time to be safe to use, without any damage to other components,
specs: http://www.coolermaster.com/powersupply/masterwatt-lite-series/masterwatt-lite-230v-500w/

Different persons have different standards (some have higher standards while others have lower standards) and it's up to every person to decide how good of a build quality components are safe to use in their PC.
Since i care a lot about all my PCs, i won't put a low or mediocre quality unit into my PC that fails to meet ATX PSU standards set in place for all OEMs to follow, so that the PSUs are safe to use and doesn't damage other components.
In fact, i've gone above and beyond regarding PSUs in my PCs. Some may call me nuts that i payed €206.80 for a PSU that sits in my Skylake build (Seasonic SSR-650TD) while i would've been safe with a PSU that costs €69.70 (Seasonic SS-520GM2). While that can be true and i could've saved a lot of money, i feel safe and comfortable that my main PC is powered by the best offered by Seasonic.
I won't suggest expensive PSUs to you when your budget is way restricted. But i still suggest getting a PSU that at least meets all the ATX PSU standards, even if it's fully wired (like Seasonic SS-520GB).

Here's also the link to an ATX PSU standard if you're interested in reading it,

As far as PSU availability in your country goes, you do have good quality PSUs available there (checked 5 different local stores).
For a good quality PSU, you can go for Antec High Current Gamer HCG-520M sold at this store,

Also, with Antec High Current Gamer 520W, your PSU has resale value (e.g 50% to 70% of purchase price) when you're done with it.

You will never make any money with that spec in a 1.5 years. I'll be surprised if you make 0.1 of a bitcoin (or any other currency) in that time. Spending $150 will be wasted, plus probaly $100 in energy costs. You will probably also need 2 cards.

The problem with mining is that the longer a certain currency runs for the harder it is to find the coins. I read somewhere that for bitcoins 10% of owners own 80% of them. This is because they started mining about 5+ years ago. And most newer currencies don't have the same value.

Don't listen to youtubers, they are just all talk.

Use the $150 on a watch or something. Better still go find a girlfriend and use the money for dates. You'll get better rewards from that.

Now I'm like even more confused
@Aeacus
Well you didn't mention that is double the cost and as you're a PSU freak you should probably know that the higher the rated wattage ... The lower the effeciency would be on lower loads ...

@Bungle11
Well I might get some benovelent fund in a month or two and subtracting 8000 rupees for a #good.psu and stacking my savings I would end up with roughly 120$ .... Which would get me r9_280 / r7_370 / hd_7870 / gtx_680 / rx_550 ... The best here is r9_280
Now just read this.

Of course better quality PSU costs more than low quality PSU since it's built by using better components.

I'm not a PSU freak but instead a PC enthusiast. Also, i have over 20 years of experience regarding PC hardware. And as far as wattage vs efficiency goes, that depends on how big of a gap there is between low load and PSU's 50% load. That, and also how efficient PSU itself is. You can't expect the same level of efficiency from 80+ Bronze unit as you can expect from 80+ Titanium unit.

Antec High Current Gamer HCG-520M is 80+ Bronze certified and even if you put a 100W load onto it, PSU is 85% efficient. Max efficiency what this PSU can do is 86.5% @ 210W load,

I'm not saying that you must go with better quality PSU. What i'm saying is that it isn't smart to buy a low quality PSU IF you care about your PC. If not, then feel free to go with Cooler Master MasterWatt Lite series PSU. But keep the fire extinguisher at hand.

@Aeacus
If you think antec generally makes better quality psu's

[Aeacus]

You do realize that the review you linked contains Antec VP series which is far lower quality unit than the Antec High Current Gamer, right?

Also, Antec doesn't make PSUs. What Antec (and Corsair and EVGA and many others) do, is buying a PSU from OEM, putting their branding on it and then selling them under their name. Antec VP series is made by Delta Electronics, Corsair VS series is made by Channel Well Technology and Cooler Master MasterWatt series is made by HEC/Compucase.

As far as who makes the best PSUs, that's Seasonic. Seasonic is both the retailer and OEM. For example, the Antec High Current Gamer is made by Seasonic and it uses the Seasonic S12II platform.

@Aeacus
0-0 ... Well you do know your fair share .... Anyhow I still couldn't get a clear answer to my original question ... Should I paste it in another forum ? Do you know any cryptomining forums ??

 

[Aeacus]

As i said in my 1st reply, no-one can give you exact answer due to the variables and uncertainty regarding to the cryptocurrency. But if you feel that you can get a better answer from cryptocurrency dedicated forum then here's one such forum,
