I have all the parts ready for my build.
Corsair 4000x Case.
H100i Aio Cooler.
Samsung Pro NVE 1tb
Rog Strix E Wifi 2 Motherboard.
5900x
Corsair RM850X

Now I was only planning on getting a 3080 or a 3080TI, however I have just grabbed a MSI 3090 Suprim X. Will my PSU be good enough for this system and card or will I need to send the 850W CPU back (before I open it) and get the RM1000X? I'm hoping it will be ok as will have the hassle of sending back, paying for another PSU and delaying the build. However what to make sure I don't have any power issues.

Please let me know asap so I can grab another PSU if needed!? Thanks so much in advance.

Yep, it will power that rig no problem at stock speed. Overclocking = 1000w

I believe it comes factory Overclocked.
Do you mean if I tried to overclock it further or overclock the CPU I would need higher?

It has took me so long to get to the point of ordering parts. Then a last min snap decision to go with the 3090 Suprim as apposed to the 3080TI in a f#$k it moment at half 3 in the morning. Now scrambling wondering if I have enough juice for it.

From looking, the Corsair is decent and is Gold Rated, do hopefully won't trip of the card has any power spikes.

Is the 1000W CPU's mainly for people that want to Overclock and/or run more than one GPU?
Thanks so far.
 
Thanks people.
Just checked and FE is 360W and the card I have says pulls 420W.
I may look into mining with the card when not using to get some of the outlay back.
Like I said, never meant to skimp as was dead set on a 3080 or TI.

I will go ahead and build with the 850W PSU then, if people are doing ok with theirs. I had just read a few folk talking about power spikes from 3090 and PC's resetting.

It's early life will be a spot of gaming at 1440P and possibly bit of Nicehash when not using it.

Looking forward to it. Not done a new build in 12 years, so time to get dirty with all the icue and different cables.
Coming from a i7 2600k (At 4.3ghz) and an Overclocked Vega 56. So should be a decent hump in performance.
 
If only I hadn't been in a rush for next day delivery. I would have gone for the RM100X. I ended up getting the HX1000. (80p a year, wow, I got suckered into the Platinum and cost more must be better)
Both say they have Jap Capacitors. Has the HX1000 had an upgrade or is it the old build repeated?

I notice on the PSU it says Single or Multi on the switch. What should I be putting it on?
