Intel Core i5-8500 8th Gen | 8GB DDR4 RAM | 256GB NVMe SSD | Win 11 Pro/Home | PCIe x16 Slot | 500W 80 PLUS PSU | GPU Power Connector
The HP EliteDesk 800 G4 Tower is HP's premium business tower desktop — built to enterprise standards for reliability, performance and longevity. Powered by an Intel Core i5-8500 6-core, 6-thread processor (8th Gen, 3.0GHz base / 4.1GHz Turbo), 8GB DDR4-2666MHz RAM, a fast 256GB PCIe NVMe M.2 SSD and Windows 11 Pro fully activated out of the box.
What sets this tower apart from smaller form factor business PCs is its genuine upgrade potential. The full-size tower chassis houses a full-length PCIe 3.0 x16 expansion slot for a dedicated GPU, a 500W 80 PLUS rated power supply with enough headroom to power a mid-range graphics card, and a dedicated GPU power connector already present on the motherboard. This means you can buy it as an everyday work PC today — and upgrade it into a capable gaming or creative workstation simply by adding a GPU.
💡 Suggested GPU Upgrades (not included — examples only):
⚠️ GPU examples shown are for illustration only and are not included in this listing. Always verify GPU compatibility and power requirements before purchasing a graphics card for this system. GPU performance will be influenced by the i5-8500 CPU in demanding titles.
The HP EliteDesk 800 G4 Tower in this listing is fitted with a 500W 80 PLUS rated internal power supply. With the i5-8500 CPU drawing approximately 65W under load, this leaves over 400W of headroom for a dedicated graphics card — comfortably accommodating most popular mid-range GPUs including the GTX 1660 Super, RTX 3060 or RX 6600 without stressing the PSU. The 80 PLUS certification ensures the PSU operates at 80% efficiency or higher, running cooler and more reliably than uncertified units. This is a significant advantage over standard SFF or Micro desktops that typically ship with only 180–250W power supplies.
