I plan on buying a Ryzen 7 5800x when it is released and I already purchased a 3090 (still waiting for it to show up though). 

I want to upgrade my RAM as well to 32GB but I can't decide which model to get. 

I was looking at the Vengeance RGB Pro 32GB DDR4 3200MHz CL16 Dual Channel Kit (2 x 16GB) & the HyperX Fury RGB 32GB DDR4 3200MHz CL16 Dual Channel Kit (2 x 16GB).

They have the same specs and I can't really find an article that compares the two. Which one is better?

 

I also currently have a 1000W power supply and was wondering if I should be looking to upgrade that as well. Looking at the specs of the 3090 & 5800X it seems like 1000W should be enough but I'm worried that maybe it won't be.

For ram, both kits have identical specs (and I'm pretty sure they also have identical timings), so just go with the one that's cheapest or that you think looks better. As for the power supply, 1000W will be more than enough. The 3090 pulls around ~400W in most cases, and the 5800X has a predicted TDP of 105W, so you've got plenty of headroom, even for overclocking. 

Always remember the 80/80 rule of project management. That is, the first 80% of the project takes 80% of the time, and the last 20% of the project takes the other 80% of the time.

Nvidia says total system power for a 3090 is 750w.

Considering both kits of RAM are DDR4-3200 CL16, they are probably using the same DRAM IC chips, too.

Just one is form Corsair, and the other is from Kingston.

Pick whichever one you prefer more, or whichever one is cheaper.

 

That said, with Ryzen, get higher frequency RAM if you can...if the price is not much more.

For Ryzen 3000-series, ideally is ~DDR4-3600 (so you are 1:1 with the Infinity Fabric, and running at full speed).

Rumors say AMD increase Ryzen 5000-series the 1:1 Infinity Fabric frequency up to 2000 MHz? (so DDR4-4000).

As for the PSU, according to reviews, a 850W will be enough for an entire system, including a single RTX 3090.

Given it is a quality 850W unit, and not some janky 'Chinese sweatshop' grade unit.

If you have a 1000W now, no need to upgrade.

3090 can pull around 400 watts and the 5800X is not measured yet (because it isn't out yet) but I highly doubt it will push far past 125 watts

I WILL find your ITX build thread, and I WILL recommend the SIlverstone Sugo SG13B

Draws 400 watts under max load, for reference.

Dual Xeon X5560 - 24GB ECC DDR3 - GTX 750 TI - old Seagate 1.5TB HDD - Dark moded Ubuntu (and Win7, cuz why not)

So from my understanding having a lower CL is better than having a higher RAM speed. So a 3200Mhz CL16 is better than a 3600Mhz CL18. Is that correct? 

Cause from what I see on Memory Express all of their 3600Mhz RAM have a CL18. (I could look on NewEgg but I just want to clear this up first).

Well...you need to do some math to figure that out.

You kind of need to balance both frequency and timings.

 

For an example:

DDR4-3000 CL14 is overall slower than DDR4-3600 CL16 ..

 

Quick-and-dirty way to calculate the latency in nanoseconds...

Example:

DDR4-3000 CL14 is 2000 * 14 / 3000 = 9.333 ns

DDR4-3600 CL16 is 2000 * 16 / 3600 = 8.88 ns

DDR4-3600 CL18 is 2000 * 18 / 3600 = 10 ns

DDR4-3200 CL16 is 2000 * 16 / 3200 = 10 ns

 

There are a lot of DDR4-3600 CL16 kits around; I'd look for those instead.

DDR4-3600 CL18 are usually the crappier bins of DDR4-3600 CL16.
