Refurbished i9-11900K gaming desktop

This refurbished mid-tower system pairs an eight-core 3.50 GHz Intel Core i9-11900K with a GIGABYTE Vision GeForce RTX 3080 Ti 12GB GDDR6X graphics card. It runs 32GB of G.SKILL TridentZ RGB DDR4 3200 memory and a 2TB M.2 2280 PCI-Express 3.0 x4 SSD. Windows 11 Pro 64-bit is pre-installed on the Z590 platform.

Who this suits and who should look elsewhere

The build targets gamers and creators who want strong 1440p or 4K frame rates from a single GPU and value the 12GB GDDR6X buffer. Buyers who need more than 32GB of system memory, a second graphics card, or a newer CPU socket should consider other options. The 850W 80 PLUS GOLD supply leaves limited headroom for heavy overclocks.

The spec that decides fit

The graphics card uses a PCI Express 4.0 interface while the Z590 chipset and Core i9-11900K provide PCI Express 3.0 lanes, so the GPU will operate at 3.0 speeds. If your workload demands full 4.0 bandwidth for storage or compute, this platform will not deliver it.

Questions about this item

Will the i9-11900K 125W CPU stay cool under sustained loads with the 280mm radiator and dual ML140 fans?

The 280mm radiator with dual ML140 RGB PWM fans is designed to handle the i9-11900K 125W TDP. Four additional 120mm case fans in the CORSAIR 500D RGB SE provide airflow across the motherboard and GPU.

How loud is the system when the RTX 3080 Ti and i9-11900K run all day?

The 850W 80 PLUS GOLD power supply runs efficiently, reducing waste heat. ML140 PWM fans and four 120mm case fans adjust speed based on temperature, keeping noise lower than fixed-speed coolers under continuous gaming loads.

Does the GIGABYTE Z590 AORUS ULTRA motherboard include Wi-Fi 6 so I do not need a separate card?

Yes, the board integrates Intel Wi-Fi 6 AX200 for wireless connectivity. Windows 11 Pro 64-bit is pre-installed on the 2TB M.2 2280 PCIe 3.0 x4 SSD, so the PC is ready to use with only a monitor, keyboard and mouse.
