Primarily used as a Premier Pro render machine with some light gaming. My "old" Ryzen 5 1600 machine was having issues with memory for whatever reason and just would not cooperate well above 2666 MHz. After Intel announced Coffee Lake and with Ryzen 2 months away, I decided to pull the trigger on an 8700k given its superior single and multicore performance compared to the 1600. I got great deals on the memory since it was on clearance at Frys, and the monitor because it was on sale at Newegg.

This build went surprisingly well. All memory detected and running XMP with no issued, CPU, storage, and GPU all recognized by the BIOS and successfully posted first time it was powered on. The only real issue that arose was that DP/HDMI output wouldn't work without graphics drivers so I had to get out a crappy Dell monitor from 2006 to install windows. Some of the thumbscrews that secured the back of the case seemed to go missing during installation but the two that remain seem to do a fairly nice job of holding things together. Kinda wish that the GPU came with a backplate though given its price tag. The computer runs pretty much inaudibly even under heavy load despite being in an open air case.

Coffee Lake runs HOT

I used the built in 5 GHz overclock profile on the motherboard and so far it seems to be rock solid with Prime95 running 3 hours without crashes. Could push it a bit further but the CPU is close to hitting 90o C on the package thanks to IntelPasteTM . Planning on delidding to lower the temps, but given the absolute scarcity of coffee lake chips at the moment, it doesn't seem like its worth the risk of being without a computer for three months.

Part Reviews


Runs really hot while overclocked but performs well. IGP is helpful for diagnosing video card issues. Also marked up everywhere because Intel's production line seems to be running in a time warp.

CPU Cooler

Easy to install, quiet, all of the cooling performance, none of the fluff.


Good motherboard for the price, easy to navigate intuitive UEFI, wifi, 3 M.2 slots, and RGB lighting.


Performs well with low-ish latency, but the red color is a bit distracting if it doesn't go with a build theme.


Fast primary storage, throttles a bit under heavy load but still a lot faster than SATA.

Video Card

Good video card but for the price it should have included a backplate.


Open air, great thermals, easy to build and work in.


Great monitor if you can get a good deal on it. Minimalist look (provided the back isn't showing) and the included stand is ok. Would have liked to see VESA mounting though.

Buys 3000 dollar pc, uses foldable desks lmao. nice pc build looks awesome!

PraeceptorXS submitter 1 Build 1 point 16 months ago

Thanks man, the folding desks are temporary until I can get something sturdier (preferably on sale) at IKEA during the holiday season.

BaconZz 2 points 16 months ago

I think this pc would look sick with some rgb ram and some rgb fans for that radiator. thats expensive though. Good look getting your desks and nice build!

nice loving the rgb

Kshitijgoel15 1 Build 1 point 16 months ago

Nice build and that monitor is looking great

WyrmWolf130 1 Build 1 point 16 months ago

Needs more RGB

How's the PSU? I'm actually planning on buying it and replacing my current one.


PraeceptorXS submitter 1 Build 2 points 16 months ago

It runs quietly but the cables are a bit stiff. I had to invert the orientation because the CPU power wouldn't stretch all the way to the top. However Newegg has a deal on the RM 750i during black Friday I believe for 79.99 which is fully modular and has a higher wattage rating.

How are you liking the motherboard? The aorus gaming 7 motherboard is on sale for 179 right now, I’m between the 5 and 7 right now. If I can save any money on this build then I would love to do that haha. Basically I want good internet connection with WiFi if possible ( this is first build and it seems like it would be easier to have included rather than buying an expansion and installing it or whatever you gotta do).

This is my build for now I5 8600k Gtx 1070 ti DDR trident ram 3200 rgb 159.99 Thermaltake rgb aio 109.99 1tb storage with 35 dollar 120gb ssd kingate (os and overwatch) Evga 750w 79.99 gq Coolermaster H500P

I haven’t even started looking into monitor keyboard mouse too much but I have my eye on a 1080p gsync 144hz that’s 269 on Newegg and Steelseries apex M750 and DeathAdder elite. Any suggestions for this build would help so much! I’m really nervous about putting it together and have literally watched hundreds of videos on builds with Z370 Mobo and Intel chipset.

Sorry for the late reply. The Gaming 7 adds another ethernet port at the expense of WiFi, which, unless you something like 10 gigabit ethernet shouldn't matter all that much. It also has additional USB 3 ports. In terms of overclocking, the Gaming 7 has a better VRM on paper but from my experience the VRM and heatsink on the Gaming 5 aren't much of an issue (the heatsink barely feels warm to the touch after extended use). I would recommend the Gaming 5 for the included WiFi however.

Jorgy1234 1 Build 1 point 15 months ago

Thanks for your response! I’m definitely going to b going with a WiFi included motherboard so the gaming 5 or the Z370 gaming Asus e is another one I’m looking at. I love gigabytes rgb on the aorus board so we’ll see! I still don’t have the CPU yet so I’m not in a huge rush but if I can get a deal on cyber Monday I’m going to pull the trigger.

Jorgy1234 1 Build 1 point 15 months ago

Is this power supply enough for this build if I do a slight overclock? I’m looking at a 650w gold certified Evga psu just like you

Nick-Pirlo 1 point 14 months ago

Really nice build but I advise you to do a manual OC, the stock configs are pushing too much voltage to the chip. You can lower VRM and package temps significantly if you manually OC. You should not be getting 90 degrees Celsius on the package with an AIO like that.

Set the multiplier to 50 and voltage to 1.3 and see what that gets you.
