[SOLVED] Connect 850W psu and 1200W psu possible?

[Minecraft_Potato]

Hi, I have an ASUS 1200W Strix Thor psu with a screen on it to show the power consumption, but sometimes it shows 1250W or 1300W. I am afraid it will damage the components. I have an 850W EVGA power supply thats lying around. Is it possible to use both power supplies to power the system? Thanks!

Do not do that. Could end quite badly.

More information needed.

Update your post to include full system hardware specs and OS information.

Cooling system?

Drives: make, model, capacity, how full?

Peripherals?

How old is the Asus 1200W PSU? Originally new, refurbished, used?

When does the display show 1250W or 1300W? What is the computer doing when the high wattages are displayed?

Are you using multiple GPUs? Heavy gaming, video editing, or even bit-mining?

What country are you in ? US outlets are generally 1850W or lower. Granted you may not use 2000W, but you could.
A 1200W power supply with an AC draw of 1250W might be OK because of the efficiency of the power supply. I don't know which part of the power supply is measured in your case.

Thanks for the reply. The drive I use is a 500GB SSD, its pretty much empty.
CPU:i7 9700K.
GPU: duo 3090 and duo 3060.
Cooling system: bequiet cpu cooler
MB: Asus Z390-A
Other devices: two GPU risers

The Asus power supply is brand new

When high wattage is displayed, the ystem is mining.

I am planning to put a waterpump and waterblocks on the two 3090. I am afraid it will need more power. Thats why I want to connect another power supply.

Hahaha yea I saw from an old post from this forumthat its not a good idea. I was wondering if things might have changed

I am in Canada, I assume its the same as US. I was just trynig yo increase the upper power limit of the system without buying a new power supply

Out of my comfort zone to suggest specific PSUs and connections. There are multiple options and factors.

There are relevant links available. For example:

https://bytwork.com/en/articles/two-power-supplies

https://www.nsm.io/2021/02/12/dual-power-supplies-on-a-miner/

All in all quite doable - just that there are risks involved and details matter.

My suggestion is that you first determine the power requirement of your mining rig, including and adding in power requirements for pumps etc. to be added.

Then decide how you will power it all, one large wattage PSU or two smaller wattage PSU's. Plan it all out in detail and post accordingly.

Ask questions if and as necessary.

Find out about your outlet wattage. You do not want to smell smoke.....
