It was time for an upgrade from my old 6700K. I had intended to get back on HEDT earlier, but nothing really scratched my build-itch, from cases to motherboards, most new components were unexciting to me.

That changed with the release of the 2950X and 2990WX, but it took a while before I could carve out the time to build. I settled on the 2950X with the idea that it would be able to do everything reasonably well.

The reason I settled on the Strix X399-E was purely because of slot spacing, I wanted to use the Wraith Ripper which would not be possible on a Zenith Extreme unless I gave up the use of the first PCIE slot.

I also knew I wanted a larger case again, after having gone with ITX and MATX for the past couple of years. The Corsair Obsidian 500D and the Phanteks Evolv X were my only choices, and I eventually chose the 500D because I like the sleek front panel more.

Originally, I had intended to buy new graphics cards, but after various preorders kept getting pushed off into the future and uncertainty, I populated the system with one Strix 1080 Ti and one Strix Vega 64 I already owned. I might change these for an explicit dual-card or even single-card setup in the future.

The AX1600i PSU is probably overkill even with everything at full blast, but I reasoned that I won't have to buy another PSU for a decade or so. I really like the build quality and relative compactness of the AX1600i and have a feeling it'll survive many rebuilds and changes.

The actual build went about as smoothly as expected, I knew going in that the 500D is based on an older tooling and has many vestigial quirks and problem areas. The fact that the PSU only mounts from the side, and not from the back on a detachable frame, while having to clear a tiny steel lip that's part of the frame, made installing it a chore and I didn't like how I felt I would scratch it up just from seating it.

The cable channel on the back is much too small, there was no way to get all the cables under the annoyingly narrow cable cover, even so I had to smush the cables forcefully to be able to screw in the two thumbscrews that secure it. The two EPS cables are zip-tied and ruin the cleanliness of the SSD area somewhat, but there was no other way to make it work. There was also no way to connect the front USB3 type A-header, the grommet was simply positioned incorrectly. This would not be a problem with an ATX motherboard, as opposed to the X399-E which is E-ATX, and I'm not overly bothered by it. I also left off the front audio header and reset switch because I never use them, but I did connect the USB type C-header.

I'm still tinkering and dialing in the system and haven't decided on what to do graphics card-wise, so this build is subject to change.

...and here i thought perfection would not be obtainable.

Thank you :)

I like all of your builds, Trump Tower in particular, got to love the creative use of orange and the orange Trident Z!

Say what now?? I have to go check that out lol.

philphaser 12 Builds 1 point 2 months ago

haha...thx! =D

legendarypoet 13 Builds 3 points 2 months ago

Ah yes, power. Shares some DNA w/ my main rig. Very nicely done!

Ixxa submitter 2 Builds 2 points 2 months ago

Oh, Cotton Candy was a definite inspiration when putting this together :) I checked out that build quite a few times.

How's running 2 sticks per channel of what I can only assume is Hynix M working out for you? Had to clock it down, or bump any voltages in a significant way?

legendarypoet 13 Builds 2 points 2 months ago

Nice! I run them @ 2933. No other tweaks needed. It's actually Samsung B-Die as reported by Thaiphoon Burner.

Ixxa submitter 2 Builds 2 points 2 months ago

Aha, I never knew the newer Vengeance was B-die, I always assume Hynix whenever i see 16-18-18-38, but maybe that's more of just how Corsair bin their chips.

Wow your CPU costs as much as my whole build

But the question is, can it run minesweeper ?

Lion_is_balanced 4 points 2 months ago

NASA computers can run minesweeper at only low settings, we didn’t reach the ability to run minesweeper at max settings yet

Lion_is_balanced 2 points 2 months ago

Awesome build you got there, nice job +1

Somerando 2 points 2 months ago

Sick PC. The Wraith Ripper uses a 120mm and you could replace the internal fan with a Noctua NFA-12X25 for better temps and noise.

Ixxa submitter 2 Builds 3 points 2 months ago

I have that in mind, in case the noise becomes overbearing, but so far it hasn't, it's my first big air system in quite a while and the steady hum of the fan is kind of soothing. If I were the type to have a workstation in or near my bedroom, I would probably not like it, but since this system is situated in my study/library it's fine :)

IngeniousTinkerer 2 points 2 months ago

You can bet your left kidney it runs Crysis! Amazing build mate! +1

Why didn't you get a 2080 TI Duke?

Ixxa submitter 2 Builds 3 points 2 months ago

I'm very partial to the Strix coolers/cards, and I already owned the 1080 Ti and Vega 64 so I just put them in. Nothing wrong with the Duke, just don't think two of them would've looked as good, and let's face it, this is a vanity build as well as a workstation that'll be used as such :)

SwiftSeb 6 Builds 2 points 2 months ago

your builds are something else, so well made. the calibre of parts is second to none too. Fantastic Pc :))

Ixxa submitter 2 Builds 3 points 2 months ago

Thank you :) Calibre of parts = Asus shill, amirite? Just kidding!

SwiftSeb 6 Builds 2 points 2 months ago

nothing wrong with being a fan

Looks pretty good but can it run Minecraft

dgraney 1 Build 2 points 1 month ago

That cable management is pristine

Ixxa submitter 2 Builds 1 point 1 month ago

Thank you :) I hated cable managing this, the case is really not very good from that point of view, but in the end, it's the final result that matters, I guess.

HiroNewf 2 points 1 month ago

This setup is a BEAST. I am looking to do a threadripper build myself. Not as big as this one though. What is your CPU running temps wise? Do you think I need to use that CPU cooler made the the TR4 CPU's or would be ok with the other AIO coolers? The AIO coolers say that they support the TR4 CPU's but idk if it is big enough to cover the whole CPU.

Ixxa submitter 2 Builds 1 point 1 month ago

Currently sitting at 34C, about 12-14 degrees above ambient, and you'll surely be fine with an AIO unless you're looking to push the very limit.

It's true that Asetek AIOs that use the bracket you get with the CPU does not cover the whole heat spreader and are slightly less efficient because of it (NZXT, Asus, Fractal, EVGA etc), you can use the Enermax Liqtech II which offers full coverage, or the new Corsair Platinum ones which are not quite as good, but offer more coverage than their other ones (H150i Pro etc).

HiroNewf 2 points 29 days ago

ok thanks. I will not be needing the full power of this PC i am going to make. It is more of a "look what I have pc" The games I play are Minecraft (clearly the most demanding game out there) Skyrim, Forza, Rocket League, and Undertale. Skyrim and Forza are a bit more demanding but still no Tomb Raider demanding.
