Can I start mining on my old PCs?

If you want to get a maximum from your old computer, what are you talking about masternode set up? You will easily make from your computer a server and after that you can get also a good profit. (Instead of byuing hardware, you will invest into a cryptocurrency, to have enough coins for a setup)

If you want to mine, why don't you choose POS?

People who use 6 video cards minyut $ 50-100 Your computers look like a parity. Perhaps something can be minted on them. But I'm sure the electricity bill will be much more than a profit.

Ya,according from my research an old model of pc has more need power supply than new model and it cost too much so for overall even you can get profit from your old pc it will still small profit at all coz you are using a highly cost power of a computer.

Just wondering if I can utilize my old PCs to start mining cryptos. But not sure where to start for those old types of equipment. Need advice.
Here is some small information about the equipment I have in my storeroom:
What I'm looking for? Which GPU should I buy for each PC? I mean which one will support with them. Also, you can suggest any CPU mining coin.

1. Quad-core 2.9, Intel G41 mainboard, 8 GB RAM, 1 GB internal graphics
Which GPU best suits this one for mining? (if any)

2. Core 2 Duo, Intel G31 mainboard, 4GB RAM, 1 shared graphics
Which GPU best suits this one for mining? (if any)

3. Core i5-650, H-55 mainboard, 4GB RAM, 1 GB onboard graphics
Which GPU best suits this one for mining? (if any)


Thanks in advance for your valuable time.

If you just want to learn how to mine, sure.  You can use any of those CPUs to mine coins.  Turn one on, set up a bitcoin wallet, download awesome miner and point it at nicehash and/or mining pool hub.  Then start tinkering with it.  It'll take years to mine enough to actually get a bitcoin payout, though.

You can probably use most any of that w/ a GPU or two.  Depends on how many pcie slots/lanes each has available....but GPU mining most any alg requires very little from the cpu.  Really just need enough CPU & RAM to run the OS.

If you ever get to the point where you want to spend a little money and build a proper mining rig?  Buy a used MoBo designed for multiple GPUs & mining.  It's just less of a PITA.

It cost more electricity to mine crypto and that's being so far from the efficient in the electricity. Not only less efficient and consumes a lot of electricity but that will waste our money by buy a new model of VGA but we can't make it too go all of its performances. small profit and long ROI and it's not worth to try.

POS needs a lot of money to get decent amount and only a big players will become a winner. I prefer MN rather than POS but when it comes to the medium POS coin and it's still worth to try.

recycling old PCs is a good idea, especially yours that are still more or less up to date.
For GPU mining anything above 1050Ti will work, although hasrate is low
These setups would be aiming for low dif. coins

But there is also another type of mining you can use your PCs for - proof of stake, you can use them to install wallets and run proof of stake mining... great with older pcs and no need for better GPUs
good luck
