Mini ITX Ryzen Build

[cory21391]

Building my first mini ITX PC, already purchased the case, power supply, and SSD.  I'm hoping to use this build as a TV PC, for movies, streaming, and 1080p gaming.  Originally I planned to just use a ryzen 5 2400G and buy an rx 580 or 1070 later on.  I figured the integrated graphics would be decent enough for a few months until I get a GPU.  But now I'm wondering if I shouldn't just go ahead and get a 2600 instead of the 2400G.  Will the 2400G be a big bottleneck or can it handle gaming just fine if I add a GPU later?  Downside is if I go with the 2600, I won't have video output until I'm able to buy a GPU, and also it may require me to upgrade the power supply (which I already purchased).  I only bought a 400 Watt SFX PSU since thats all I figured I needed (load calculator with an rx 580 was around 370).  I'd hate to go with the 2400G then regret it later.

the 2400G should be fine.

Get a bigger PSU. Yes the load will only be 370 but make some breathing room for the PSU.

Get a 650 at least.
Less load = lower temp.

You don't think I'll miss the 2 extra cores?  Also out of curiosity, does the 2400G run at a lower wattage with the integrated graphics disabled?  If so this would definitely assure my power supply has a good amount of headroom so it isn't so close to being maxed out with the rx 580 added.  I'm assuming it being 400 watts means it can safely run 400 watts worth of components, but doing so wears it down faster so headroom is always desired.  Definitely the rx 580 would be cutting it close to 400 with a 65 watt cpu.

[cory21391]

650 seems a little high for only ~370 watts of components.  I had an i5 build with a 1070 and water cooling on a 500 watt psu for years without issue.  I usually build with about 100 watt headroom, but I'm guessing 50 might be ok.

400 watts is fine as long as you dint slot in a Vega and/or a 1080ti/2080ti. 

 

Gaming doesnt use eherything fully like in a synthetic load, so you are good.

The GPU may use a little power, but it'll act like any modern GPU and be throttled down unless under load.

 

Any mid-range GPU should leave you well under the power budget with a 400w PSU.

 

Just be sure to get 2 RAM sticks and run dual-channel with the APU. That really matters for it.

 

The 2400G is a modern, 4c/8t CPU. It'll run most everything just fine.

[cory21391]

I'm getting dual channel 2 x 8GB 3000 MHz G.Skill ram.  I'm thinking 8GB should be fine for a 4 (or 6) core CPU at 1080p gaming, no need to spend 2x the money on 16 gb for no reason.  The 2600 seems similar in performance to the 2400G (except for multicore tasks obviously, where those 2 extra cores come into play).

 

To add more questions to the mix, is it safe to use molex adaptors for vga power connectors?  The power supply i picked only has 1 8 pin pci power connector, and if I were to get a 1070, they require 2, meaning I'd have to get an adaptor or a new power supply.

[cory21391]

My mistake, that's 2 x 4 GB ram

[cory21391]

Of course, I could just get an rx 580 that uses 1 8 pin power supply as I had planned.  I still feel like I might regret not getting the 2600, but I really don't want to wait a month or 2 to have a functioning PC.  Here's the PC build so far.

 

Case:  SilverStone Sugo Series SG05BB-LITE Black

PSU:  FSP 400W Micro ATX12V / SFX12V 80 PLUS BRONZE

SSD:  Mushkin Enhanced TRIACTOR L 2.5" 500GB SSD

RAM:  G.SKILL Ripjaws V Series 8GB (2 x 4GB) DDR4 3000

Mobo:  MSI B450I GAMING PLUS AC

CPU:  Ryzen 5 2400G  or Ryzen 5 2600

GPU  (later):  Sapphire PULSE Radeon RX 580 8GB

With an mini ITX case, space is very limited, you have to fit in a small enough GPU. Make you you do some research. and mini ITX mobo and PSU ae quite expensive, would you consider m-atx?

the 2x4GB ram will be fne for 2400g, since its not supposed to do heavy duty jobs.

molex adapters are fine

[cory21391]

According to the specs on the case I picked, it should fit a GPU up to 10" in length (254 mm).  The max CPU height is 82 mm, so it should fit the stock wraith stealth cooler thats included.  I believe it would even fit the wraith spire cooler, not sure about the prism though.

[cory21391]

That's the one thing I dislike about the case, that its a cube shape.  But the "console" mini itx cases just seemed too restrictive height wise for the cpu cooler, and significantly more expensive, so I passed on those.

[dgsddfgdfhgs]

just looked at pic of PSU and case, PSU isnt modeler, and the cables will take up quite some space.

it will be packed quite full when completed. not to scare you, but you will need patients routing the cables. 

IMO, 2600 feels more solid and competitive than 2400g, but if you are buying a GPU anyway, just buy it now!

 

[cory21391]

Yeah, I was kind of hesitant to pick a non modular PSU for a small build, but I've seen mini itx cases come with non modular power supplies, so I'm sure its doable (but probably a huge headache that I'm not looking forward to.)  It just wasn't worth the price increases I was seeing for the modular ones (like $30-$40 more).  I feel the same way, as in I'd rather get the 2600, but I'd hate to be sitting on it for months until I get the GPU.  I figured if there wasn't much difference in gaming performance I'd just get the 2400G so I could use it now and just upgrade the GPU later.  I guess a better way to phrase it: Is the 2600's increase in performance worth waiting a month or 2, or is it a negligible difference in real world performance?

[TechyBen]

400w to 450w should be fine. It's a mini itx build. The calculator will even give you the "recommended PSU" (usually 10-20% over the actual load). Just go for the one or so up. So for 370w, go for a 400w to 450w.

 

If you had a massive GPU in (check the load for a 1080ti) and CPU upgrade, and the system checker said something like "435w" at load, then go for a 450w or 500. If really close to 450, I'd go for 500w. But then again, I like to overclock at times. If not overclocking, if not using massively compute maxing software, and if not using hundreds of drives, usb devices and fans, then getting the PSU recommended by the calculator is fine (it adds that little % extra already remember).

 

I got a (second hand) SilverStone Fortress Mini. Love it... but it is VERY tight for space.

 

[edit] Oh, here you go, needed mini PSU and Cryorg C7 for my type of build... but then again, I have swapped out the long card now for a mini GPU and took the HDD bay out to *Linus* it with double sided tape (and 2.5inch only SSDs/HDDs). Cables are a mess... but oh well. 

[cory21391]

After looking at some gaming benchmarks, using an rx 480, (2400G vs 2600) it seems the real world difference isn't so bad between the 2 CPUs.  I think I'm gonna stick with the 2400G for now.  I mean if I reeeeeally wanted to, I could always upgrade the CPU later on, maybe when zen 2 releases.  I've even considered waiting to see if AMD launches an rx 600 series later this year or early next year before adding the GPU.  The vega 56 nano would fit in the case (probably would need over 400 watts though) but it's too costly atm.  Interesting to see how much power you can cram into a small space though!

[cory21391]

Like you could technically fit a 2700x CPU and a 1080 ti in there!  Not sure about the thermal situation though lol

[cory21391]

WOW... that IS a tight fit hahaha

[dgsddfgdfhgs]

may be too late to ask, Why do you need mini ITX?

space? budget? dont want to dump case?

I really think you can buy a new m-atx PC with a decent GPU more about same cost

[cory21391]

Definitely too late as I've already ordered the case, but basically for space.  Hoping to fit the PC neatly in the entertainment stand with my TV to use as a TV connected PC.  I specifically am looking at a motherboard with wifi and bluetooth for this reason, to wirelessly connect to the internet and use a bluetooth remote/mini keyboard or something, and a controller for games  Speaking of TV PCs, are there any recommended TV apps/interfaces for easy tv viewing/navigation?  I only know of big picture mode on steam, but I'm not too sure what other functionality that provides besides gaming (or if if it does provide any other functionality).
