Description from Seller

A well-rounded PC that's a step above a "starter PC", and the 3700X and 3060 Ti have earned the gaming PC title as a primarily 1080p system.

I was going to list this as a regular ol' used PC, but while repasting and repadding the GPU I ripped a cable and, long story short, had to replace some components. The upside for you is a 60 day warranty on all components. I'm sure you won't mind!

The B550 chipset supports PCIe 4.0, and paired with the 750W ASRock PRO-750G (B+ on the SPL PSU Tier List) there's room to move up to newer PCIe 5.0 GPUs without taking too big of a performance hit. The PSU also has a native 450W 12V-2x6 cable¹ for that day. A better AM4 CPU can drop in down the line too, and the cooler will handle beefier chips.

RGB is handled 100% through OpenRGB. Since its 1.0 update I've found it more compatible with components than ever. The UI still isn't great, but once you tinker around, it's worth not worrying about ads or resource hogging.

PBO is enabled and custom fan curves are set before shipping. One note: the RAM kit is rated for DDR4-3200 CL16, but it wasn't stable at that speed, so it's running at the JEDEC default of 2666MT/s.

Specs:

  • CPU: AMD Ryzen 7 3700X (8C/16T - Arctic MX-7)
  • GPU: NVIDIA Founders Edition RTX 3060 Ti 8GB¹ (PTM7950 Repaste + Repad)
  • RAM: 16GB DDR4-2666 (2x8GB ADATA XPG Spectrix D41 RGB)
  • Storage: Samsung 970 Evo Plus 1TB M.2 NVMe PCIe 3.0 x4 SSD (100% Health)²
  • Motherboard: Asus PRIME B550-PLUS AC-HES ATX AM4
  • PSU: ASRock PRO-750G 750W 80+ Gold ATX
  • Case: MUSETEX Y6 ATX Mid Tower
  • Cooling: upHere UE2TC6 Dual Tower Air Cooler
  • Connectivity: Built-in WiFi 5 + Bluetooth 5
  • Extras: ARCTIC M2 Pro M.2 Heatsink, 12-Pin to Dual 8-Pin + AsiaHorse 16AWG cable extensions, 3D printed IO shield.

This system comes with a fresh Windows 11 Home installation (other than preinstalled apps³) and will require initial setup on first boot.


¹The HDMI on this card was a bit finicky, it would lose connection if bumped, I imagine probably just due to wear. I've included a DisplayPort Cable free of charge if you encounter issues with the HDMI.
²The 3060 Ti Founders Edition uses a 12-pin connector, so it's powered by the included 12-pin to dual 8-pin adapter. The native cable is there for future GPU upgrades.
³Drive health obtained via CrystalDiskInfo (Endurance: 600 TBW |Terabytes Read: 0.2 TB | Terabytes Written: 1.1 TB | Power-On Hours: 3,770).
⁴Preinstalled apps include NVIDIA App, OpenRGB, Samsung Magician, and Steam.
*This PC uses refurbished components, see 60 day buyer protection policy at the bottom of the page for details.
