GTX 1050 - 2Gb Vs 4Gb

[DarrenJC]

Planning a building a hobby rig, 4 or 5 cards. Looking to populate the rig with GTX 1050 cards. Im after cards that dont need extra power from the PSU, so no more than 75watts.

In terms of mining ability (Yes, its a hobby rig, im not looking to retire in 2 years) What will I notice between the 2Gb and 4Gb versions of the 1050.

Also, If im thinking about this right, using GTX cards that dont need extra power connectors from the PSU, I can run 5 cards on 1 PSU being 750watt?

Thanks in advance

I thought about 1050's aswell as i already own a 1050 ti and was able to test it and i also liked the idea of less pcie 6/8 pin plugs as this is the common shortage of all PSUs.

Here is why i went for 2 1070s instead:
-1050 2GB wont mine Ethereum, 1050 ti (4GB) is just a pain to reach any payout limits on any pool and also nicehash miner doesn't seem to like it (benchmark crashes).
-My Zotac 1050 ti only gets 2.5 Sol/W on ZEC
-It draws 75W through the PCIe slot (mainboard). I believe thats the reason why it also is not SLI Capable...you can definitely NOT pull 3,4,5 or 6 * 75W through your mainboard, it will melt...i wouldnt put more than 1 1050 per mainboard.
-Over/Underclocking is very limited (70% - 100% TDP only)...though my card reaches +650mem easy

If you really want to do this, check specifications of how much power you can draw on all PCIe slots together (I didnt check) but im sure it wont support 300W.

Really good reply, thank you.

I like the idea of going for less cards and going for the 1070+ cards too. Can always add more 1070's later

Also, the 3 fan 1070 cards do look amazing imo.

My planned rig builds is in very early stages, i wanna plan it, no rushing into ordering loads and getting the wrong setup.

I suggest you always get a PSU with at least 20% more powers than the total power consumption of you motherboard + CPU + GPUs, even though you might be able to get the system running under 750w PSU, you still have chance to burn the PSU if any power peak happens for the GPU
so the best way is to get a 1000w PSU, you will be much less worried about limiting the power o each GPU

Ive added a 1000w PSU into my price calculations. Was going to aim for 1050 cards without extra power. But the more maths I do... i want 1060 or even 1070 cards with 6/8 pin power. Granted, even if i go with 1050 cards I'd add 6pin power to take the load away from the mobo

The more I looked into the 1050ti the more I was like "ehhhh....I'd rather buy a better, used card". It's nice that it doesn't need extra power supply but that doesn't bother me. If I were buying it strictly for gaming without needing to upgrade my PSU, fine.

Now I'm back to the drawing board.
