I am currently just using an ATX power supply with the machine right now. The plugs on the 12V plug-in board prevent it from plugging in. The motherboard won't require the 8-Pin EPS connector but the APU/CPU might. The 8-pin EPS connector is absolutely necessary for the Ryzen 7 2700X but probably won't be for the APU at stock clocks. APUs can still pull a fair amount of power though.


Thanks for the heads up. I may just do so. Had I researched the Mean Well EPP power supplies sooner, I would have gone with a Ryzen 5 2600 or Ryzen 7 2700 and a RX 560 AERO ITX as that would get me near 200W and the EPP-200-12 is a 2" x 4" board. The entire build could be in a slim, console style instead of whatever this may turn into.
I just wanted to comment and say I'm running the Mean Well 200w + a cheap Realan 250w power board from Aliexpress for my 2400G APU build. Although my B450 motherboard has an 8 pin EPS connector, the Realan power board just has a 4 pin EPS connector. I just did a 90 minute stress test yesterday with Prime95 and Furmark and, although both power boards got hot, I saw no issues nor throttling of CPU/GPU clocks due to insufficient power delivery.

Note: a 4 pin to 8 pin adapter would not matter (I have one sitting in a box but chose not to use it as it takes up space in the case), as the same power draw is going through the 4 pin connector either way. I doubt the connector on the motherboard would be limiting factor.

Thank you for that comment. It will help me further plan the wiring for the build.


To catch everyone up on the past six months, Full Circle ended up being unstable under load no matter what I tried. Whether it was under Linux or Windows, a load on the GPU signified a reboot. It probably is the power supply that I was using. Since then, I packed away the parts and made moves to sell them but never did. I ended up switching main computers, building a NAS, starting another job (three now), and getting another part (not a power supply though XD). I am looking to get a "test bench" setup going in the interim to dial in the individual components before shrinking the build. I am currently looking at 16GB memory kits at moment. My current choices are:
Thoughts?

Today, I finally have a Linux distro running and stable (?) on the computer. This is with a new, temporary power supply to allow me to start dialing in efficient speeds and voltages for each component. I have not put it through the paces of compiling code or gaming, but I will soon. Currently looking at memory, storage, and a different motherboard for it (MSI has better VRMs overall). Power conversion and delivery will have to wait until the Meanwell EPP-500-12 lands several weeks from now. I will bide my time by designing a chassis for it. No restrictions.

Been working on this machine still. Dialed in the voltages for the CPU (-0.1V for now) and RAM (1.355V for now) so far. The GPU is to come especially as I plan to go with a smaller heatsink for it. Unfortunately, getting Radeon ProRender working on any of the Linux operating systems that I have tried, has been fruitless. That was one of the main reasons for having such a powerful card. I am now in the process of installing Arch Linux. I also had borrowed another m.2 drive from a friend/colleague to have a bit of extra space to work with for now until I get the ADATA XPG SX8200 Pro that I want.

I have been considering my options for the "final" build of Full Circle. Do I go for the opposite-direction intake layout like Skyreach 4 Mini and Sentry 2.0, a same-direction intake layout like the P50 and S401, or an offset, same-direction intake layout like the Reaper IV Mini? Having looked at the prices of current power supplies, doing a modular 500W power delivery system will be at least 50% more than the cost of the 600W Enhance Platinum FlexATX PSU that Z-Cases sells. Going FlexATX would limit the layout of the machine but at this point, the layout would stay standard for a long time. Implementing either of the first two would bring back my RSC project as well although the Skyreach 4 Mini is very tempting to acquire despite the physical challenges that my current component selection presents.

Having gone over the entire thing and sketching out some ideas for cooling and placement, I've decided to go for the Skyreach 4 Mini (Black or two-tone? Hmmm.) to house it in. RSC was supposed to be for this machine but it is no longer necessary. I will explain more about why in the respective thread. This decision frees me up to explore (within constraints) other details related to this build and future SFF projects.

Performance
I currently still dialing in the voltages and frequencies (and timings) for various parts. I also have some tuning to do under Linux for the CPU, GPU, and storage. I have been looking at getting a new RAM kit that can hit higher frequencies with tighter timings and a new NVMe 1.3 SSD as well.

Cooling
This is the most interesting part as I have a lot to cool. The NVMe SSDs are covered. The CPU will be undervolted further and have it's frequency capped for thermals. A Noctua NH-L9a SE-AM4 will be cooling this for now. That may change in the future. The GPU is another story. Being a Vega 56, I'll need to figure out a custom cooling solution for it. RAM isn't an issue because heat spreaders.

Power
Given that I have decided to go with the Skyreach 4 Mini presents a unique challenge: Powering everything. This was something I moaned about in the "In which we discuss the evolutionary stage of the MINI" (in the Live chat at 55:18 ) as the build needs more than 200W at stock performance and power levels. While going 12V is tempting, the Mean Well AC-DC units with the right wattage are too large to be internal. The current HDPLEX AC-DC units can be made internal which is in line for the next phase of the build.

Off to do some more research now. Having trouble getting my Arch Linux live media to boot properly and looking for parts

EDIT: Reset BIOS to defaults and left the boot options alone. Arch Linux install media boots now. Onto installation now. Had a wild thought of getting four minimal-bezel, 1080p Freesync monitors for a 2x2 grid arrangement. Would give me the equivalent of a 45" 4K display without the exorbitant cost.

Ordered the Skyreach 4 Mini in black.

EDIT: *looks at cost of HDPLEX 400W combo* This may be a purchase for next month

Time definitely flew for the past three months and there is a lot to unpack here.

I did order the HDPLEX 400W AC-DC and 400W DC-ATX to power Full Circle. They arrived days before the Skyreach 4 Mini did. Seeing it beside the parts that were going to go into the build showed just how far power supply design and technology has come since I last built my own computer.

After receiving the S4M, I had then built Full Circle using the S4M and the parts that I had originally sourced for it. It was quite enjoyable getting these shots and building the machine.

When I was finished, I ended up with a small, dense, and capable system. All it needed was some extra storage and new RAM. For the storage, I got the Sabrent Rocket 1TB. This was yet another order of magnitude faster than the ADATA XPG SX6000 Lite drive that I have already installed and many orders of magnitude faster than the SATA III SSDs that I had grown accustomed to.

It was not to be however. The Sabrent drive had some bad blocks on it which led a higher load on the RAM which led to crashing when installing and configuring Linux on it. Windows did not crash which I attribute to the quality of the ADATA drive. For now, I'm going to take a step back, plan a new build, sell some parts, buy some parts, and assemble and setup a temporary iteration of this build.

I rebuilt Full Circle in an open air test bench configuration for the time being. Will be using it that way until I have a concrete plan for the next iteration and have earned and saved up enough funds for implementing the next iteration.

I will add the relevant pictures to this and previous post in the near future.
