RX480(580) cards real power draw, 1000 watts psu for a 5-6-7 RX 480 builds ?
⭐ Merited by Lutpin (10)
In the past few days i saw in many post when members keep telling the newbies you can go safely with a 1000 watts psu for a 5-6-7 RX 480 cards , the mining is not a real stress to those RX 480 cards , those cards never pulling close to 200 watts , gpuz or afterburner what telling you how much power your cards using ... ( Rx580 cards using slightly more power than RX480's )
Some "Hero ranked" members still believe GPUz or Afterburner measuring the vga cards total power usage...
Yes you can run 5-6 or maybe 7 RX480 / RX580 cards from a 1000 watts PSU safely, with a proper bios mod ( not just paste and copy mem straps) , undervolting / underclocking , BUT this is not for a newbies who asking questions like :
Just bc i had a few minutes free time
and i had a RX480 card on my bench test pc , i just created a custom bios for that card ,hex edited , optimized to ETH-SC dual mining ... Im going to post some picture about the real power usage of the RX480 cards with different stage of the process . You can also compare the Afterburner (or gpuZ ) reported gpu power usage to a whole vga card power usage .
Sorry about the large files , but this way newbies can see the picture better
This is my own experience with RX480-RX580 cards.... and building mining rigs for years

The PSU should be a EVGA or CORSAIR 1200 watt , fully modular and Platinum rated like the Hx1200 from Corsair, this PSU can keep up 5 cards even if they are running near 200 watt but that is not the case because when you are mining Ethereum they are consuming 135 watt each from GPU-Z or MSI afterburner app.

Hi bitcointalk, I want to build mining rig but I dont have the slightest idea how will i build one and how much would it cost me.
Want to start a small miner at home, any tips?

test bench / idle power usage
when you are mining Ethereum they are consuming 135 watt each from GPU-Z or MSI afterburner app.
If gpuz or afterburner showing you 135watts for ETH , your bios is not optimized at all , the only mods you have is probably copy/paste mem straps , changed some voltage in polaris editor, and undervolting with AB or any other software !
