Major update for all silent / air / passive cooling enthusiasts!
Today I have tested RCC-MID1 compatibility with the Thermalright Silver Arrow T8 together with the plug-in Rgeek 450W DC-DC PSU.
Long story short: its working great!
CPU Thermal Test
R3800X @ full load: ΔT = 50°C (40% CPU fan)
R3800X @ full load: ΔT = 64°C (semi passive, case fan only)
Rgeek 450W DC-DC PSU Test
This rather cheap plug-in PSU works totally fine. I've run stress tests with my RTX2070 and 3800X simultaneously (about +/- 300W system power) and didn't observe any problems. At first I thought there could be some issues with the PCIe and CPU power cables because they only use AWG22 but it turned out to be totally fine. The DC barrel connectors coming from the
TWO DELL power bricks are getting pretty hot but still well below the commonly used 80°C thermal rating.
Summarizing: If you are looking for some cheap but powerful plug-in DC-DC power supply for a setup with up to 350W power requirements we have a working alternative. If you really need 400W I would recommend the G-Unique or 400 distro from JHack.
Case Update
The first 15 (beta) cases will be ready in about two weeks. These might still have some minor flaws but are totally fine to use. When everything is ready, I will inform everyone on the waiting list about the price and shipping cost.
After my tests today I have made some small but important design changes to support giant coolers together with DC-DC power supplies. Same like the radiator support, people will have a choice which power supply they would like to use (read: use pliers if you want to use a SFX PSU).
This change will be coming for the
next, bigger quantity production batch.
