BitFenix Colossus Micro / i7-4790K / R9 295X2

by philip

Description

Full build video here: https://www.youtube.com/watch?v=zTjPkYZ1wzY

Thermal benchmarking: https://www.youtube.com/watch?v=VGDSF3DfVbA

The BitFenix Colossus Micro is a perfectly practical case. However, the components we chose to put it in are not. It was the perfect storm - we had on-hand an i7-4790K CPU and a Radeon R9 295X2. The question was - can it fit? Yes! Barely.

We knew from the start we'd likely run into some fit issues. Putting two CLC radiators in such a small case was going to be problematic. Just fitting the 295X2 in the case when it also used a vertical mount power supply was tricky. Most power supplies that have enough wattage for the 295X2 are too long. Fortunately the Corsair AX860i had sufficient wattage and left roughly 1/2" of clearance for the video card. Like I mentioned - this build was not about being practical. It was all about what we could manage to squeeze into the case. I had the 295X2 on hand, so it begged to be used. For science!

Before anyone comments that we should have used part X instead of Y, or Q instead of Z, know that this part selection was not aimed at practicality. Different use cases prefer different part selections. Maybe you don't need an i7. Maybe you don't need 16GB of RAM. Or maybe the 295X2 is a tad more horsepower than you need to play Minecraft. I chose these parts for a couple reasons:

  • I enjoy smaller form factor builds and the associated cable management challenges.
  • The i7-4790K and Radeon R9 295X2 were already on hand (for benchmarking, the results of which hopefully everyone will see soon).
  • Because we could.

"Because we could."

Perfectly valid reason! +1

Doubt this will even run Minesweeper, at least you tried philip +1

Great Build +295x2

Frostfyre 1 Build 8 points 54 months ago

Woah! you fit all that in a mATX? Wow! +1 all the way!

Cool build. What kind of temps do you get from the CPU/GPU under load?

PcNoobLord 5 points 54 months ago

Now it is only a matter of time, before the prophecy unveils in front of us. When he spoke of the Pentium "K", we rejoiced in happiness. Now he will show us its true powers through his next marvelous creation. We wait here, Phillip, to see the mighty screwdriver of all power to wreck upon the screwdrivers that lie on the case of your planning. Our dearest hopes will be with you on that day of glory and excitement. Good luck, o brave Phillip.

Wiring up the front (side really) panel connectors must have been a pain.

Top-down airflow?

GilChris95 4 points 54 months ago

This is an extremely powerful machine for a small form factor wow. +1

A 860Watt PSU can power a R9 295X2? Wahhhhh?

Yep! The anticipated maximum draw of this build is just under 700w, so it should be plenty. When I get a chance to put it through its paces I'll have more info on the actual draw under load.

Amazing work Phil! Always nice to see the PCpartpicker team go all out. :)

DeltasEcho 2 points 54 months ago

So do you like the case?

GamerDeso 2 points 54 months ago

Oh my...

torrin1234 1 Build 2 points 54 months ago

Really cool. Do you like the M6S? I think it's great so far! Boot times are sometimes faster than my old monitor can even turn on.

wallywintrow1972 2 points 54 months ago

Outstanding,very impressive build, and built for the best reasons of all, because you can, +1

alex591 2 points 54 months ago

Minesweeper benchmarks? I think it will be around 10-15 fps. Thant is a really demanding game.

This build really highlights how manufacturers are going absolutely crazy on the size of closed-loop CPU radiators. The radiator on that H80i is twice as thick and has twice the fans as the cooler for the 295x2. Yet the hottest CPU on the market has a 220W TDP, and that video card is over 500W. It's even more unbalanced with the 4790k, which is an 88W part.

I kinda wish the 295x2 had a bigger radiator. It runs close to the throttle point of 75 on a warm day in a crossfire setup with a 290x.

Video removed? Any idea when it will be back? Super interesting build, would love to see it.

Ok, second upload looks to have gone through - it's up now (woo!)

gammin1234 1 Build 1 point 54 months ago

Epic a super computer in a mATX form factor. +1 from me!

MockSeventy7 1 Build 1 point 54 months ago

I like this one a lot. Cable management in that case with those parts would definitely not be the easy

actechy 7 Builds 1 point 54 months ago

Nicely done, as always +1

CarterBond 1 point 54 months ago

I want to make a website like this for bikes. Lol

elias2001 1 Build 1 point 53 months ago

Do you use two 25A to power or 25A and 71A

racsorrac 1 Build 1 point 45 months ago

Lol mate I'm not sure if this can handle Minecraft

GentlemanShark 1 Build 1 point 37 months ago

How do you like this case? How would it stack up against the likes of the 350D or Enthoo Evolv for a custom loop?

NewCarSmell -6 points 54 months ago

But can it run turbo tax??
