Hi Guys

Just want to find out if the Following Power Supply 850W Gold+ https://www.amazon.com/FSP-Modular-Certified-Compatible-AU-850PRO/dp/B007P8DKBQ

Would be Able to Power a Rig with 3 x Zotac GTX 1080 Extreme Amp Edition
I am having the issue where the PSU is Clicking and then after a while PC powers off.

I think it might be overloading, Is that Possible?

Thanks in Advance

Each of those cards can pull 210-238 watts on stock settings (100% power limit) plus the system should pull another ~70 watts so the PSU should handle it (700-784W load).

Unless you're setting a higher power limit or the PSU is in a very hot place.

Thanks for the Reply

I thought as Much as I have another Rig with a 4 x MSI GTX 1070 Gaming X Running on a Corsair 850w Gold with no problems,

I have the 1080 Cards Set to 75% Power and it seems to be stable now.

Its Winter here so its Cold GFX cards are running at about 44*C.

I have another of the same PSU to setup Ill see if its just a Bad PSU.

Thanks

If it's stable at 75% then I'm pretty sure it's the PSU. I could only find a review of the 1000W model and that's apparently pretty good. Maybe yours came from a bad batch or just faulty?
Those PSUs also have two over temperature protections in them so one could trigger under load or could be faulty.

Or maybe the issue comes from the risers, but it's doubtful.

Solution is simple, buy Digital Watt Meter (Kill A Watt) - Measure your electricity usage and you will always know if your power supply is enought.
