10 great PC upgrades for under $100

The PC hardware market has suffered due to the AI boom, driving up the cost of typical PC upgrades. Instead of spending hundreds on more RAM or a new SSD, consider more affordable sub-$100 enhancements. It's unlikely to find a $100 component upgrade that can boost frame rates or switch from 1440p to 4K; a new power supply might be the best option.

What can you add to a PC for $100? Reputable companies like Noctua and TP-Link offer high-quality upgrades for less than $100. Discover some of the best PC upgrades under $100. The Universal LCD Screen costs $84.99 and can be used as a standalone or mounted on a compatible PC case. Utilize it for USB-powered secondary displays, monitoring PC performance metrics, or controlling music via your media center.

Peerless Assassin 120 SE air cooler, priced at $34.90, is an excellent upgrade for dusty old or stock coolers. Compatible with both Intel and AMD CPUs, this air cooler provides improved heatsinks and fans, offering overclocking headroom or extra performance if thermal bottlenecks arise. The Arctic Liquid Freezer III Pro 360, priced at $69.89, is an exceptional AIO cooler for advanced cooling, particularly if you already have a decent air cooler and a compatible case.

Remember to check compatibility; this model requires space for a 360mm radiator. These fans from Noctua, priced at $34.95, are the best we've tested for silence and airflow. Perfect for upgrading your AIO radiator or any other part of your case, these fans ensure quiet yet efficient cooling. Lastly, the Be9300 PCIe Wifi 7 Card, previously priced at $69.99 now $49.98, can be installed on any compatible motherboard, offering speedy Wi-Fi 7 without much hassle. Save a bit more by opting for the Wi-Fi 6E version, which still delivers a significant upgrade.
