Description

It was finally time to replace my aging X79 rig. Originally I was going to go with the X299 platform but once I heard Coffee Lake was being released sooner than expected, I held off.

The parts in this build were chosen to be cost effective, yet of reasonable quality. If it isn't obvious by the parts list, I like RGB lighting. At first, I was just going to reuse everything from my old rig (CPU, MOBO, RAM aside), but decided to go with a smaller form factor. Typically, I stick with ATX or larger builds, but seeing as how Multi-GPU setups are becoming a thing of the past, I no longer need the space. The only part reused is the Strix 1080 Ti. It is going to be replaced with a GTX 970 so the old computer is still fully functional.

CPU: I currently have an i7 3930K, so going with anything lesser (total threads), was not an option in my mind. Therefore the only CPU choice was the 8700K. While its arguable that the 8700K isn't much faster than an overclocked 3930K, its single thread performance still blows it away. This rig will primarily be used for gaming, hence wanting the higher single core performance.

Cooler: Great reviews, RGB. Original plan was to go with the Swiftech H240 X2 Prestige, but I could never find one in stock, and ultimately it wouldn't sync up with the rest of the RGB lighting.

Motherboard: This is a place holder until the ASUS Strix Z370-G becomes available. Impatience is a sad thing, but I couldn't wait 2-3 weeks for the ASUS motherboard to become available. It will be swapped ASAP and sold at a loss.

Memory: Fast enough, very tight timings, RGB. For only $60 more than it's cheapest competitor (at 3200mhz), it offered substantially tighter timings and it has RGB lighting. I went with 2x 16GB for expand ability. Aesthetically, using 4 dimms would have looked much better. XMP is currently not working with motherboard. All settings must be entered manually for it to boot correctly.

SSD: Fastest M2 drive available. 500GB should suffice for OS and a few games. 1TB was on the wish list but couldn't justify it's price.

HDD: Cheap storage, fast enough for its purpose.

GPU: Looks good, performs good, stays cool. Lighting will sync up with motherboard once I get the ASUS.

Case: I've been eyeing up the bigger brother to this case for about 2 years. Once an mATX version came out, I was sold. Fairly simple case to work with, albeit with a few draw backs. It's difficult to see in the pictures, but with a larger PSU, you have virtually no space to work with. I had to choose which cables I needed, and then install the PSU. There is only about 1inch of clearance between the PSU and the HDD cage. In hindsight, I could have removed the HDD cage first, and then installed PSU. Also, the magnets on the back panel aren't quite strong enough. Even with the cables tight and in place, there is still too much pressure on the panel for the magnets to make proper contact.

PSU: Cost effective, quiet, and I've never had any issues with Corsair. 1000w is definitely overkill. I like headroom, and the CPU and GPU will be overclocked. I also wanted the option to SLI in the future, should I ever decide to. If I would have gone with a more conservative 850w PSU, there definitely would have been more room for the cables between PSU and HDD cage.

Fans/Lighting: I weighed out my options, which were limited to Thermaltake or NZXT for sync-able lighting. Ultimately going to with NZXT was the cost effective route because the fans and HUE+ were on sale. The CAM, GSkill and MSI lighting software do not play nice together. Hopefully some software updates come out soon to alleviate the issues.

Overclocking: I've managed to overclock it to 4.8Ghz stable @ 1.285v. Under typical loads, it doesn't get hotter than 73c. Using Prime95 and Intel Burn Test it got up to 90c. The stress tests were done with the Kraken X62 at max fan and pump speed. Under gaming/typical testing, the fan/pump was set to performance mode or 50%. At 5.0ghz, the cpu simply gets too hot. It will require a custom loop or delidding to have temperatures I'm comfortable with. Once the 8700K is readily available, I will be delidding mine. While overclocking, one of my memory dimms decided not to light up anymore. Definitely super buggy software. The memory is overclocked to 3466mhz @ 15-15-15-36. I'll be tinkering more with the memory later.

UPDATE: Delidded processor. 20-22c decrease in IntelBurnTest. Also, fan and pump can be run at 50% rather than max speed to get these results. Details updated to show max temp under stress test.

Pay no mind to the prices listed. They are not accurate. I will update the price list when I can find all of the receipts. Keep in mind, CDN dollars.

73 celsius @ stock? damn

DoHbOyBlAzEd submitter 18 Builds 1 point 2 months ago

That's under prime 95 load for 2 hours. After the TIM settled it, the temps settled around 73c

bigfrigginhero 1 point 2 months ago

I would love to see your overclocking results! congrats :)

DoHbOyBlAzEd submitter 18 Builds 1 point 2 months ago

I was tinkering with some over clocking but it screwed with the RGB memory. So now I'm tinkering trying to get it working again. PITA.

However, I could boot at 5ghz no problem. Just didn't get a chance to tweak voltage and run P95

izlud 1 Build 1 point 2 months ago

Graet build !!! Please post more OC results

DoHbOyBlAzEd submitter 18 Builds 1 point 2 months ago

Posted some in the description. 8700K = hot.

LuxLikeFun 1 Build 1 point 2 months ago

8700k = Hot + The Evolv is known to have bad airflow, even with a rad. I think most people will see high 60s to low 70s with a 240/280 Rad.

DoHbOyBlAzEd submitter 18 Builds 1 point 2 months ago

I don't think these temps have anything to do with the case. The temps you said are exactly what I got while stress testing @ stock. Under regular use it never really goes over the 65c mark. As soon as you start throwing voltage at these cpus, they're rediculous. Even overclocked the temps are on par with reviews.

MuchLinux6500 2 Builds 1 point 2 months ago

Nice! 8700k! Woah!

Colinpail 1 point 2 months ago

Did you say that you were putting the 1080 ti back in the old system and the 970 in this one? How does that make sense of this build is going to be used for gaming? Other than that great build!

DoHbOyBlAzEd submitter 18 Builds 2 points 2 months ago

Other way around. A GTX 970 is going into the old rig.

Vicepter 1 Build 1 point 2 months ago

JayzTwoCents made an interesting video covering something called "Multi Core Enhancment" on the z370 platform. I would look into that to get a bit of added performance. But Nice build man.

MASS- 1 point 2 months ago

why does it say Kaby Lake in Core temp?

DoHbOyBlAzEd submitter 18 Builds 1 point 2 months ago

I'm going to assume because Core Temp hasn't been updated in awhile. I downloaded the newest version available.

ohhh mate, a rig this nice deserves custom-sleeved cables!

You must be super excited to see the performance difference! Great build +1 for sure

haha im still rocking an ''aging'' i5 2330 and a 770, nice build. I'm envious.

dadiman260 1 Build 1 point 2 months ago

can you post cine bench score not overclocked? there was some controversy over these and i wonder if maybe the reviewers got specially selected chips.

DoHbOyBlAzEd submitter 18 Builds 1 point 2 months ago

I'll check shortly and see what I get

MannyPCs 1 point 2 months ago

Absolutley Stunning. +1

Also, Congrats with the first i7 8700k build on PCPP!!!

eli_harper13 6 Builds 1 point 2 months ago

Awesome build man! Are the CPU-Z bench scores at stock speed, OC, or all cores running at 4.7 (I know some mobos turn up all cores to run at the max turbo speed)?

DoHbOyBlAzEd submitter 18 Builds 1 point 2 months ago

The CPUZ score shown is the processor @ stock. I can upload a pic of CPUZ @ 4.8ghz if you'd like.

eli_harper13 6 Builds 1 point 2 months ago

Yeah that would be great! I am trying to see how it compares to my 5930K. I have considered upgrading but I don't really thing it would be a performance increase that I would actually notice.

DoHbOyBlAzEd submitter 18 Builds 1 point 2 months ago

Update to the latest version of CPUZ and post your bench results

eli_harper13 6 Builds 1 point 2 months ago

I keep my 5930K at 4.6GHz and that scores 508 single thread and 3817 multi thread. This is my build:

https://pcpartpicker.com/b/nfpG3C

DoHbOyBlAzEd submitter 18 Builds 1 point 2 months ago

3930K @ 4.6Ghz (Old CPU) Single: 460 Multi: 3330

8700K @ 4.8Ghz Single: 565 Multi: 4254

The difference is fairly substantial. At 5Ghz CPUZ benched single @ 599 multi @ 4450

Games like PUBG are seeing quite heavy gains, even at higher resolutions. However, we all know PUBG is an unoptimized piece of ****.

bigbodyben 1 Build 1 point 2 months ago

Please post your new temps after you delid. Golly thats really hot for having a krakenx62 but man that thing is beastly. good build +1

DoHbOyBlAzEd submitter 18 Builds 1 point 2 months ago

I'd like to be dissapointed with the cooler, but imagine how hot the CPU would be on air...lol

bigbodyben 1 Build 1 point 2 months ago

lol i cant even imagine it! like would it even work? especially a stock cooler? would ppl's computer just turn off every 30 minutes or something lol

ajmalik 1 point 2 months ago

Why Microatx?

"...but decided to go with a smaller form factor. Typically, I stick with ATX or larger builds, but seeing as how Multi-GPU setups are becoming a thing of the past, I no longer need the space."

Leleedler 1 point 2 months ago

I'd be interested in coffee lake if the temps were better, sticking with my 1700x, hope Ryzen 2 fixes some of the single core issues as far as gaming goes.

DoHbOyBlAzEd submitter 18 Builds 1 point 2 months ago

Can't really blame ya. I have a 7700 (nonK) in a SFF case, and even undervolted it's hotter than I like. If Intel would just use better TIM. I honestly think they use poor TIM to limit over clocking results and make people delid, voiding their warranty.

DominicBoccella 1 point 2 months ago

NICE

ThatOneBudgetGuy 1 point 2 months ago

damn that thing is beautiful. i was thinking of getting a new NZXT kraken like the one you've got. they're amazing looking.

If only i had the money :P

Carlster 1 point 2 months ago

God dammit I NEEEEEEED that cpu my guy! But congrats on getting one. :)

DoHbOyBlAzEd submitter 18 Builds 1 point 2 months ago

Honestly, I've gotta be like 1 of 100 in Canada who's gotten one. Super lucky on my part.

Carlster 1 point 2 months ago

If there was even 100 of those CPUs to go around.

DoHbOyBlAzEd submitter 18 Builds 1 point 2 months ago

Yea even I'm skeptical there was that many. Only one retailer in Canada got stock and sold out in about 2 minutes

DoHbOyBlAzEd submitter 18 Builds 1 point 2 months ago

I wish I bought 2....lol

Schrodgod 1 point 2 months ago

Have you thought about putting a ASUS Rampage motherboard in it would really match the RGB scheme. Great build!

DoHbOyBlAzEd submitter 18 Builds 1 point 2 months ago

Unfortunately I am very limited with options as the motherboard needs to be mATX

0v0_sosa 1 point 2 months ago

Hey, Amazing build!!! Do you think you could upload a picture of your full setup?

DoHbOyBlAzEd submitter 18 Builds 1 point 2 months ago

I just added some. Last 3 pictures posted

terrencer87 1 point 2 months ago

Awesome build! But why does the CPU Temp readout in pic 17 say Kaby Lake and not Coffee Lake?

DoHbOyBlAzEd submitter 18 Builds 2 points 2 months ago

Core Temp hasn't been updated since Coffee Lake has been released. So it detects it as Kaby Lake.

Jbj5000 3 Builds 1 point 2 months ago

I ordered an 8700k as well. I have the same case as you. Just waiting for the Strix Z370g to go on sale now.

DoHbOyBlAzEd submitter 18 Builds 2 points 2 months ago

I wanted to wait for the 370G, but I'm way too impatient lol

Jbj5000 3 Builds 1 point 1 month ago

I feel you. Wish Asus wouldn't neglect Matx, all the Itx and Atx boards went on sale the day of coffee lake launch. Pre ordered it on Amazon but they aren't giving me any info on when it will ship.

DoHbOyBlAzEd submitter 18 Builds 1 point 1 month ago

I called a few stores across Canada and they all expect the 370G the 19th October or shortly after.

Jbj5000 3 Builds 1 point 1 month ago

Wow, thanks man that helps a lot. Now I have a ballpark of when it will ship. You, sir are a hero.

DoHbOyBlAzEd submitter 18 Builds 2 points 1 month ago

No problem. Let's hope Asus makes enough to go around lol

Crystalyx 1 point 1 month ago

Love the looks. Congrats on the new build!

Somerando 1 point 1 month ago

Awesome build, but why the Enthoo Evolv

DoHbOyBlAzEd submitter 18 Builds 1 point 1 month ago

Nice looking case, small. Good rad support for it's size

OccamAsylum 10 Builds 1 point 1 month ago

I'm confused at why you mounted the rgb fans to the front where you really won't see them instead of on your radiator, but otherwise it looks great.

DoHbOyBlAzEd submitter 18 Builds 1 point 1 month ago

I wasn't sure how much light would come into the case from the fans before I mounted them. I'm waiting for NZXT to make high static pressure rgb fans to mount on the rad.

Liam_Goggin 1 point 1 month ago

How many RGB headers are on that motherboard?

DoHbOyBlAzEd submitter 18 Builds 1 point 1 month ago

I'd have to take a look, never bothered to to begin with

MakoMercy 1 point 1 month ago

The temps for the CPU at 4.8ghz was 73c before delid or after delid?

DoHbOyBlAzEd submitter 18 Builds 1 point 1 month ago

Sorry, the first temps listed under Overclocking were before delidding, while under real life loads, gaming particularly.

[comment deleted]
SansYT 1 point 1 month ago

I have a question: Would you recommend delidding the 8700K? I know you did it, but I don't have much extra money, and if I screw up, it's almost 400$ down the drain, along with my warranty.

DoHbOyBlAzEd submitter 18 Builds 1 point 1 month ago

If you're going for high overclocks, definitely. If you're fine with 4.6ish GHz with a modest cooler, then don't bother delidding.

SansYT 1 point 1 month ago

Hmm. Gonna be using an H100i v2, and I do plan on going for near 4.8 GHz.

catacavaco 1 point 1 month ago

Do you happen to have CPU VRM temps and CPU power readings when fully stressed (Prime95, AVX or not) ?

WhyDoWeWonder 1 point 1 month ago

What did you do for your network adapter?

DoHbOyBlAzEd submitter 18 Builds 1 point 28 days ago

I don't understand the question...

WhyDoWeWonder 1 point 27 days ago

It's a device you need to actually connect to a wired or wireless network, for example, the Gigabyte GC-WB867D-I, linked here https://ca.pcpartpicker.com/product/tTdqqs/gigabyte-wireless-network-card-gcwb867di

DoHbOyBlAzEd submitter 18 Builds 1 point 27 days ago

I'm well aware of what it is. All modern motherboards have Network adaptors of some sort. In my case, it has LAN and Wi-Fi.

JFB 1 point 24 days ago

Thanks for posting temp tests. I've got the same CPU and cooler picked out, and have never built a computer or truly overclocked before. This is a huge help to give me a starting point.

Frank3 1 point 2 days ago
