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.

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.

wait but I cant afford any water after this build un-spits

bigfrigginhero 1 point 11 days ago

73 celsius @ stock? damn

DoHbOyBlAzEd submitter 18 Builds 1 point 11 days ago

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

bigfrigginhero 1 point 11 days ago

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

DoHbOyBlAzEd submitter 18 Builds 1 point 11 days 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 11 days ago

Graet build !!! Please post more OC results

DoHbOyBlAzEd submitter 18 Builds 1 point 11 days ago

Posted some in the description. 8700K = hot.

LuxLikeFun 1 Build 1 point 11 days 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 11 days 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 11 days ago

Nice! 8700k! Woah!

Colinpail 1 point 11 days 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 1 point 11 days ago

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

Vicepter 1 Build 1 point 11 days 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 11 days ago

why does it say Kaby Lake in Core temp?

DoHbOyBlAzEd submitter 18 Builds 1 point 11 days ago

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

nw85967 1 point 11 days ago

Wouldn’t it be cheaper to just get the hero and not sell it at a loss?

DoHbOyBlAzEd submitter 18 Builds 1 point 11 days ago

The Hero is full atx, won't fit in the case

hi_im_snowman 1 point 11 days ago

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

DoHbOyBlAzEd submitter 18 Builds 1 point 8 days ago

I may get some, it's something I've pondered for awhile.

scwee 1 Build 1 point 11 days ago

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

dadiman260 1 Build 1 point 11 days 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 10 days ago

I'll check shortly and see what I get

MannyPCs 1 point 11 days ago

Absolutley Stunning. +1

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

eli_harper13 6 Builds 1 point 11 days 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 11 days 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 11 days 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 11 days ago

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

eli_harper13 6 Builds 1 point 11 days 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 10 days 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 11 days 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 10 days 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 9 days 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 11 days 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 11 days 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 10 days 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 10 days ago

NICE

ThatOneBudgetGuy 1 point 10 days 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.

N0_N4M3 1 point 10 days ago

Wowowow waiting for the builds with 8700K since launch :) Super cool build! +1

armorcadet 1 point 10 days ago

First 8700K! GG!

If only i had the money :P

Carlster 1 point 10 days ago

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

DoHbOyBlAzEd submitter 18 Builds 1 point 10 days ago

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

Carlster 1 point 10 days ago

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

DoHbOyBlAzEd submitter 18 Builds 1 point 10 days 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 10 days ago

I wish I bought 2....lol

Schrodgod 1 point 10 days 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 10 days ago

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

0v0_sosa 1 point 10 days ago

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

DoHbOyBlAzEd submitter 18 Builds 1 point 9 days ago

I just added some. Last 3 pictures posted

terrencer87 1 point 8 days 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 8 days ago

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

Jbj5000 2 Builds 1 point 8 days 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 8 days ago

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

Jbj5000 2 Builds 1 point 8 days 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 8 days ago

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

Jbj5000 2 Builds 1 point 8 days 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 8 days ago

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

Crystalyx 1 point 3 days ago

Love the looks. Congrats on the new build!
