Power Supply for 4 Gpu- 750 Watt is Enough?

[parshuram]

I just set up a mining rig with Conf :

- Intel i3 - 6098P CPU
- Asrock - Z170 Extreme 3
- AMD Powercolor RX 480 GPU - 4 gpu
- Kingston 120 GB SSD
- Corsair RM 1000x PSU.
- windows 10 Enterprise x64
- Ram DDR4 HyperX Fury 2133 Mhz

power consumtion of the above GPU is 150 watt/GPU. Whther I can shift to another power supply of 750 Watt? . Will it affect my rig?

Kindly help.

I would say it is too tight for a 750w psu on the settings you run.
System + gpus should pull over 700w combined, pretty much no room for spikes there.

If you underclock the gpus it is possible though.
Underclocked 480 8GB cards should pull around 115w on stock bios @ ~27Mhs

You should get minimum of 1000W of power, 750W won't be enough

Yes it will be enough, you can even dual mine.

You will just have issues plugging in your risers because you can't use the SATA and you only have 2 chains of Molex connectors. And the 750W PSU most likely only has 4 PCIe cables.

As has already been said I would not recommend you to try running 4 GPU's. You should really be looking at a solid 1000w psu, alternatively you could run 3 GPU's on the 750w psu and pick up another small psu to run the other card off.

I personally had 4 gpu mining rig that i tried out with corsair 850w and seasonic 1050w power supplies, and with the 850w one it was pretty unstable
which is why i later switched to seasonic 1050w which solved all my issues.

I wouldn't recommed you going to 750w with 4 gpus, even if the calculations say it should be able to run it. You have a good setup with 1kw you have, don't
risk it - mining rigs should not be made with so little space for fluctuation, in the end you want it to be rock stable and run 24/7, and not have to worry about
if your PSU will die or not..

Alternative option would be what user above mentioned - using another small PSU to even out the scale, but once again - it's much cleaner and simple with one strong PSU. (cable wise)

I wont even try without 1000+ watts
You could try it out by hooking them up 1 by 1 and test when it fails to keep it all stable.

An EVGA G2 750w would do it, but the actual consumption of 480s is higher to me. Or you could run them at low clocks to cut down on power. Skimping on PSU is bad stuff.
