Description

Finally decided to write this up. Everything works great! No real issues other than not getting the RAM to run at 3200MHz with default timings, though I suspect that it's because of ASUS's not-so-great BIOS updates (or rather lack of) and the fact that the new Ryzen 3900x has only been out for a month. For a first time builder, it was a little stressful putting everything together, but after a weekend of some stressful moments, I'm so glad to have finished it.

For those wondering about GPU clearance, my EVGA 2080 Black is 269.2mm, and there's ~15-20mm space between the GPU and the radiator (rough eyeball estimate).

Quick product reviews:

  • CPU: Ryzen 9 3900x. Wow, what a CPU. Runs nice and cool, even under load. Haven't properly stress tested it, so the CPU temp under load that I gave (65°C) is a bit of a rough estimate based on what I've seen so far. EDIT: Just ran Cinebench R20, hit 90°C. EDIT2: So I gave in and installed the NZXT CAM software (blocked the spyware part in Firewall, so let's hope my data isn't getting sent to them), and changed the fan speed for the Kraken. Ran the test again, sat at 83°C.

  • GPU: EVGA 2080 Black. Runs really nicely. Had I waited a month, yes I would have gotten it for a fair bit cheaper with the release of the super cards, but I'm still happy.

  • Thermal Compound + CPU Cooler: Thermal Grizzly Kyronaut + NZXT Kraken x52. Due to my own idiocy, I almost broke the clip that attaches the motherboard, but works great. I replaced the stock thermal compound with Kryonaut and I'm pleased with CPU temperatures being nice and comfortable.

  • Motherboard: ASUS ROG Strix B450-I Mini ITX. BIOS update will be needed for Ryzen 3000 CPUs (BIOS 2301 or later), so make sure it's updated before installing your CPU. Otherwise, one of the best ITX motherboard out there. Pretty good VRMs, second to the MSI B450I Gaming Plus AC, and the BIOS is nice too. Everything was easy to install on the motherboard, no issues really at all. I had to clear CMOS a couple of times when getting my RAM up to rated speeds, but that wasn't too difficult (n.b., this was patched in later BIOS updates, this bug no longer exists afaik). There's also only 1 USB 2.0 Header, see below for why this was an issue.

  • RAM: G.Skill Flare X 16GB 3200MHz CL14. It's Samsung B-Die, what more can you say really. Super fast, works great with my Ryzen 3900x. I haven't tried getting it up to 3600MHz CL16 yet, but when I know that there's a BIOS out that is quite stable for memory OCs, I'll give it a shot. The B450-I supports 3600MHz officially, but you might be able to push it to 3733MHz for ideal performance in terms of latency. EDIT: I'm now running it at 3600CL16 with no issues as the BIOS is more stable now.

  • SSD: Samsung 970 Evo Plus 250GB. To be honest, I bought this before I knew about a cashback promotion that Samsung was doing, so I could have easily gotten a 500GB SSD for not that much more. No issues whatsoever, super happy with the insanely fast boot times.

  • HDD: Seagate Barracuda 3TB 7200RPM. Not too much storage, not too little. Perfect for my steam library.

  • Case fans: NZXT Aer 2 RGB 120mm. Default colour is white, which matches the colour scheme of my case, so I haven't downloaded the spyware that is the NZXT CAM software in order to control the RGBs (or has that already been cleared up?). Very quiet, but also effective in keeping the interior cool. EDIT: So I got the CAM software, but blocked any outgoing connections in Firewall, so hopefully my data isn't getting sucked away. I mainly got the software to control fan/pump speeds but the RGB aspect is fine too.

  • Case: NZXT H200i. I love this case. Had a little bit of difficulty fitting everything in there, and my cable management is horrendous. But everything fits nicely. The RGB controller and the whole NZXT ecosystem was a little tricky to figure out at first, but I soon figured out what I was doing. It's a great case, and the front panel and tempered glass panel is awesome to look at. Dust filters are included for the front panel, top fan, and the power supply at the bottom.

  • Power supply: EVGA Supernova G3 650W. Works great, can barely hear the fan at all. It even has a little motherboard ATX cable testing kit, so you can check if your ATX cable works fine or if it's borked before testing your components on it.

  • Custom cables: Cable mod white sleeving kit for the Kraken x52 and black/white power cables for motherboard, CPU, GPU and SATA. They look awesome in my case, but my god the installation of the sleeving kit it a bit of a nightmare. The clips are hard to fully get around, and even a month after installing them, they've popped off a little and the ends have frayed a little. Looks great, but it was a damn pain to get on.

  • Monitor: ASUS ROG Swift PG279Q. Had I waited a month or two longer, I would have probably gone for the LG 27GL850. I'm not really an expert when it comes to monitors, and I can't notice it that much, but there is a bit of that typical IPS orange glow that is really only noticeable when I'm watching a dark scene in a video. Other than that, it's an awesome 1440p 144Hz IPS monitor, and the OSD is easy to navigate with the joystick thing at the back. The DP cable that comes with the monitor works great, no issues whatsoever.

USB 2.0 Header Issue: With most ITX boards, if not all of them, they'll come with only 1 USB 2.0 header. Which is a bit of an issue when you're using a CPU cooler that needs a USB 2.0 motherboard slot, because it is already taken by the RGB Controller that comes with the H200i. I instead had to use a NZXT USB 2.0 Internal Hub to fit the 3 USB 3.0 slots that I needed (the NZXT Kraken x52, the NZXT Hue 2 Controller, and the RGB Controller that comes with the case). The only issue that this presented me that there wasn't a lot of room for this to go in the bottom of the case, but I managed to somehow make it fit in there.

You will have to ensure you never lose standby power because there's a BIOS bug where if you lose standby power, the system will refuse to post because it reset the DRAM voltage to 1.2V after losing power.

The only guy doing ASUS BIOSes is on vacation for a week, so don't expect a BIOS update to fix this until 1-2 weeks from now.

Yeah I had that bug for a while but clearing CMOS wasn't too tricky. Still annoying though. I did update the BIOS recently (I was on 2703, now on 2801) and it's been fixed since then.

A new bug popped up where soft reboots turn into failed coldboots. You can fix that by making the MemCadBusClkDrvStren at 20ohms and ProcODT at 60ohms or 53.3ohms. Was able to properly reboot with these settings applied.

Hey mate, just wondering as to where you put the hdd, would love some pics of the back of the case!

  • 2 months ago

Hey man, sorry for the late reply (it's been a while since I've been on here). The hdd is down at the bottom of the case, just next to the bottom of the Kraken radiator. There's space down there for a single 3.5" hdd, but space becomes a bit tight. I'd recommend using a SFX power supply if you are going to put a hdd in there, or even if you aren't cos the ATX power supply is huge in case.

No worries big man, I managed to squeeze it in there. Been up and running for a few months now, and new monitor has just arrived today. Thanks anyways :)

How come you didnt go 3600 ram?

Do you know if rgb ram stick will fit this case with the aio cooler?

  • 2 months ago

The 3200 ram was cheaper, and the Flare X is good at overclocking up to 3600CL16 as it's good Samsung B-Die. I've currently got it running at 3600 CL16 even if it's rated at 3200 CL14.

As for weather or not the RAM would fit, I actually took a risk here because I wasn't sure if it was going to fit or not. I've got about 4-5mm of diagonal clearance, and from the front-on view it looks as if they are touching. I was happy to take the risk because if it didn't fit, I could have just turned it 180° and turn off the RGB on the Kraken so that the text wouldn't be upside-down. You could always check other builds using the Kraken and this motherboard and see what RAM other people are using to get an idea of clearance.

how can you run the kraken, aer fans and lightstrip without hue+?

  • 2 months ago

The NZXT USB 2.0 Internal Hub allows me to use 3 USB 2.0 headers for the space of a single USB 2.0 header on my motherboard. I do have a Hue+ in there, which is connected to the Hub along with the Kraken, and then the Hub is connected to the motherboard.

So single 2.0 header on mobo to nzxt hub then attach kraken, aer fans and light strip? Does the hue plug into smart controller?

I was curious about the RGB controller issue because i have the newer version of this case also and having trouble with getting the RGB setup. Was the additional hub the only option to make it work? Beautiful build!

AFAIK the additional hub was the only way for it to work. And thank you!

Can you tell me how are your GPU temps?

  • 1 month ago
  • 1 point

Max I've ever seen is 85, but usually hovers in mid-70s and low 80s at 100% usage. I'm getting an SFX power supply soon so that there's more breathing room for the GPU fans too.

Hey man, Such a clean build! Just wanted to ask a few questions, I have pretty much the same build as yours except I have the 3700x. I'm getting CPU idle temps at about 50-60 and while I game like CSGO temps are at about 70-75. Sometimes even jumped to 80. Would you have any ideas why? I haven't made any adjustments in the bios yet?

That is one beautiful build.

I am thinking of doing something similar, but with a 3700x and 2060 Super. I am sure mounting will be the same.

Do you reckon a 2TB NVME SSD is a good buy, or should I stick with a 500GB boot drive and HDD?

Would you say the custom cable for the x52 is worth my time? It looks incredible, but as a total novice, I am not sure I would be as successful as you were.

Once again, beautiful build!
