Next up, I picked up two important upgrades from the mail. The new RAM and a PSU capable of feeding the whole system without breaking a sweat.
As 8 GB of RAM was far too little, I decided not only to double it but to jump up to 32 GB. My ambitious goal being huge impact, smooth multitasking, and no waiting on loading bars.
Unfortunately, beginning my search for RAM sticks I immediately everywhere found only worry about what had been a time of cheap RAM turning into a time of RAM prices that skyrocket. My timing for the upgrade wasn’t ideal, but it was unavoidable.
After some searching, I found the Dual-channel Corsair Vengeance RGB 32 GB (2×16 GB), DDR4 2666 MHz.
The limit to 2666 MHz doesn’t really matter, because my B360H4‑EM motherboard and i7‑8700K support up to 2666 MHz. Higher-speed RAM wouldn’t improve performance, and when we upgrade to AM5 in the future, we’ll will have to switch to DDR5 anyway. So this kit is optimal and still in closer to the “cheap RAM” prices.
With 32 GB of RAM, I now believe I can have Unity compiling scripts, OBS recording, video exports, Krita open, and a browser with many tabs… all at once with no waits. Previously, with the old 8 GB stick, projects stalled, previews lagged, and background builds froze the editor.
Now? Every tool gets its lane. Unity compiles while OBS records, Krita stays snappy, and nothing pauses to catch up.
Extra bonus: full dual-channel bandwidth for the B360H4‑EM motherboard. Maximum stability, zero compromises. RGB is just a little extra but we won’t really see it in the closed Medion case.
Power — Silent, Strong, and Ready
Opening up the Medion case and checking inside, I found a Medion OEM 450 W PSU. Adequate… barely. The RX 9060 XT alone can draw ~250 W, the i7‑8700K ~95 W, plus the rest of the system — it was flirting with the limits. Connectors are few. Efficiency is okay, but under stress the tiny fan would scream.
So I had to start searching for a budget PSU, and I didn’t want to spend money twice so I really wanted to find one that will pack enough punch to carry on into future upgrades too, but still with a cheap pricetag. And despite these impossible demands, there actually was a PSU that stepped up and met all the criterias.
Enter the Cooler Master MWE Gold V3, 750 W, 80 Plus Gold.
This PSU brings extra headroom — system stays cool and stable under full load
Modern connectors — PCIe 5.1, EPS 4+4, enough for next-gen upgrades
Efficient & quiet — Gold efficiency, better fan, DC-to-DC voltage stability
Future-proof — supports AM5 CPU, 64 GB RAM, next-gen GPU without needing a replacement
With this PSU, fans won’t ramp unnecessarily, voltage should be rock-steady, and the system won’t hesitate when asked to do everything at once.
So:
The NVMe removed disk bottlenecks
The i7 removed hesitation
The Assassin cooler removed instability
Now, RAM removes memory bottlenecks
And the PSU removes power limits
