Overview

The Lenovo Legion Tower 5 (90RB001PUS), upgraded by GreatPriceTech, is a gaming and productivity desktop that punches above its price class thanks to generous memory and storage upgrades. At its core is the AMD Ryzen 7 5700G — an 8-core, 16-thread processor with boost clocks up to 4.6 GHz and 16MB of cache. This chip excels at multitasking and handles CPU-bound games, streaming, and content creation tasks with ease. The 64GB of DDR4 RAM is far beyond what most gaming desktops ship with, making this machine equally capable as a workstation for video editing, virtual machines, or running large development environments alongside a gaming session.

Graphics duties are handled by the NVIDIA GeForce GTX 1660 Super with 6GB of GDDR6 memory, a proven 1080p gaming card that delivers smooth frame rates in esports titles and respectable performance in more demanding games at medium-to-high settings. Storage is a dual-drive arrangement: a 1TB PCIe SSD for the operating system and frequently played games, paired with a 3TB HDD for the rest of your library, media, and backups. Connectivity includes Wi-Fi 6, Bluetooth 5.2, and a generous selection of USB ports including USB-C 3.2 Gen2. The system ships with Windows 11 Home, a one-year Microsoft 365 Personal subscription, a USB keyboard, and a hub. The 400W power supply is the main limiting factor for future upgrades — a more powerful GPU will likely require a PSU swap — but as configured, this tower is a well-rounded system ready for 1080p gaming and heavy desktop workloads out of the box.

  • AMD Ryzen 7 5700G eight-core processor handles both gaming and productivity workloads
  • GTX 1660 Super 6GB delivers solid 1080p gaming performance across a wide range of titles
  • Includes Microsoft 365 Personal subscription and USB keyboard for immediate out-of-box use

👎 Cons

  • The 400W power supply limits future GPU upgrade options without also replacing the PSU
  • GTX 1660 Super is an older mid-range GPU that struggles at resolutions above 1080p

Frequently Asked Questions

Yes, this unit has been upgraded by GreatPriceTech. The 64GB DDR4 RAM and 1TB SSD + 3TB HDD storage configuration exceed the standard factory specs. The core platform — Ryzen 7 5700G processor, GTX 1660 Super GPU, and Legion Tower 5 chassis — remain as originally built by Lenovo.
Yes, the Legion Tower 5 chassis supports standard PCIe graphics cards. However, the included 400W power supply may need to be upgraded if you install a higher-wattage GPU. Check the physical dimensions of any replacement card against the case clearance as well.
The GTX 1660 Super with 6GB GDDR6 handles 1080p gaming well in most titles at medium to high settings. Expect 60+ FPS in popular esports games and 40-60 FPS in more demanding AAA titles at 1080p. It is not designed for 1440p or 4K gaming.
No, when a dedicated GPU like the GTX 1660 Super is installed, the system uses it as the primary display adapter. The Ryzen 7 5700G's integrated Radeon graphics are effectively disabled, though they could serve as a backup if the dedicated card is removed.
The package includes the Legion Tower 5 desktop, a USB keyboard, a hub, a power cable, and a one-year Microsoft 365 Personal subscription.
