Considering crypto mining

[Rikimaruu]

I have two rx580 from 2017 that I use for gaming what type of power supply is enough to run these two graphic cards for mining? The old dead power supply was 650watt

Hey fellow miner! Welcome!
That PSU will be enough!

Here is current screen from small rig running 3 Rx 580


I'm using Phoenix miner and cards draw around 80w each.
To save you of headache I can give you content of bat file I'm using so you can be up and running in minutes

depends on the algo you want to mine, but 650w is enough for 2 cards.

Its just two of those rx580 so the 650watt power supply is more than enough for every algorithms that you want to mine, on ETH those cards takes 80watts each = 160watts and on ravencoin those cards takes up to 120watts each = 240watts, still not even close to the half of 650watt power supply.

You are wrong. This cards need 120w for ETH - you can´t use the software reading for this - AMD only show the TGP in every software - so you must add around 30-40w to every card.

Example - Teamredminer show 530w for one of my RX570 rigs - from the wall it is 880w.

Same for Nvidia, but here you must only add around 10 - 20w per card to the software readings.

Yes i know no one will hear this and no one will trust to my words, it is so annoying that so much people don´t trust to my words every time. But you lie to yourself if you think such software readings are the truth.

This is the truth. If OP is that spooked about wattage get a Killawatt  https://www.amazon.com/P3-P4400-Electricity-Usage-Monitor/dp/B00009MDBU/ref=sr_1_5?crid=HM757DH482O7&keywords=killawatt&qid=1644859015&sprefix=killawatt%2Caps%2C379&sr=8-5 get from the wall readings. Run algos, note wattage pull.

You need to measure the gpu from wall to get the actual wattage it's using, consider buying watt meter or something for watt reading, I believe the 650watt is enough to carry those two gpus because I'm using a 650watt power for a vega card and also two nvidia cards 1660ti.

Just do not buy cheap power supplies without an 80 PLUS certificate, otherwise the consumption from the wall will be about 350-400 watts.
If you don’t want to pay dearly, then look for a used 650-700 watt gold 80 plus.

You're correct but why do you have to be so dramatic?

Just to make sure,

So rig of 10x 3070, every card is averaging around 118w + 20w = 138w x 10 cards = 1380w
What about actual computer draw, CPU, etc. how much you usually add there?

I am running those on EVGA 1600w Gold PSUs
