The Best $3000 Corsair RGB Gaming PC Build – September 2022

By Ari Altman | Published August 27, 2022 | Updated September 25, 2022

Game Hard and Look Good Doing It!

If you want a $3,000 Gaming PC Build that’s a true showcase, not just another black box, then this is the one for you! In addition to the best gaming components available, it sports the latest in addressable RGB lighting and case design! We didn’t just add “RGB” to the name of this build without making sure it delivered on the looks front. The case fans, cooler, RAM, and motherboard can all be color-coordinated to make your build more than just blingy… it will be a work of art!

This Month’s Build, Featuring Intel, Nvidia, Asus and Corsair!

For September 2022, the $3,000 Gaming PC Build features the fire-breathing Intel Core i9-12900KF CPU, a 16-core, 24-thread gaming monster. It’s sitting in a great Asus Z690 motherboard and backing up a seriously-fast GPU, the RTX 3080 Ti 12GB, which has been discounted to an insane closeout price!

The rest of the system relies heavily on Corsair’s market-leading suite of components, starting with the iCUE 5000X RGB case, which stands out like no other chassis on the market. For storage, we go with a 2TB PCIe Gen 4 drive, along with 32GB of Corsair DDR5-6000 Dominator Platinum RAM. Keeping the system cool and looking great is the Corsair H150i Elite LCD 360mm liquid cooler with built-in display. Finally, powering this system is the awesome Corsair RM850X Gold-rated power supply.

The Pre-Built Option

  • The Ultra-High-End Gaming PC

    CyberpowerPC GXiVR8080A30 12900KF/RTX 3080 Ti

    EXTREME DEAL! Not ready to build your own PC? No problem! This awesome system from CyberpowerPC is equipped with a liquid-cooled Intel Core i9-12900KF 16-core, 24-thread CPU and the GeForce RTX 3080 Ti 12GB GPU, along with 16GB of DDR4 RAM, a 500GB NVMe solid-state drive, plus a 2TB hard drive. Plus it comes with Windows 11 pre-installed to make the most of the Intel Alder Lake processor!
    The Guru’s Tip

    If you're not ready to build your own, this system offers equivalent speed to our DIY PC for a great price!

The DIY Build

  • CPU

    Intel Core i9-12900KF

    Intel reclaimed the gaming lead with its 12th-Gen “Alder Lake” CPUs, and the 12900KF is the CPU to get for extreme performance when cost is no object. It handily beats the Ryzen 9 5900X and 5950X in gaming, and with its 8 multi-threaded performance cores plus 8 efficiency cores, it’s also a beast for content creation or multi-tasking!
    The Guru’s Tip

    This CPU does not come with a cooler, and it needs a serious one, so make sure to pick up the huge liquid cooler we recommend later in this guide!

  • Motherboard

    ASUS TUF Gaming Z690-Plus WiFi

    Asus as usual packs tons of performance into its “Plus” series motherboard, and this Socket 1700 model is a perfect match for Intel’s latest CPUs. It features robust 14+2-phase power stages, four PCIe Gen 4 M.2 slots, a PCIe Gen 5 video card slot, eight USB ports (including a Type-C port), and integrated WiFi 6. Note that this board only supports cutting-edge DDR5 RAM, which offers a performance boost for Intel’s latest high-end CPUs.
    The Guru’s Tip

    Most importantly for this build, this board has the best ARGB controller and software in the industry, and it's fully compatible with Corsair gear too!

  • Video Card

    Asus GeForce RTX 3080 Ti TUF Gaming 12GB OC

    The Asus GeForce RTX 3080 Ti TUF Gaming offers amazing performance and exceptional cooling. It features a triple-slot, triple-fan cooler to keep temperatures in check and allow maximum boost. It also has an overclock applied from the factory, and of course can go even higher with manual tuning.
    The Guru’s Tip

    This card's RGB lighting can even be sync'd up with the motherboard's RGB controls!

  • Memory

    Corsair 2x16GB Dominator Platinum RGB DDR5-6000 C36

    For the ultimate in speed, you must go with DDR5 RAM, but not just any DDR5 RAM, because you need high-frequency DDR5 to blow past DDR4 RAM performance. And that’s what you get with this kit, which runs at DDR5-6000 with 36-38-38-76 timings at 1.25V. It also features the most advanced RGB lighting on the market, courtesy of Corsair’s Capellix technology.
    The Guru’s Tip

    We have specifically selected an Intel-based motherboard that supports this newer DDR5 standard.

  • Solid-State Drive

    SK Hynix Platinum P41 2TB

    While you may not have heard of SK Hynix (SK is for South Korea), it’s a huge player in the memory market, being one of just three fully-integrated manufacturers. And that means it plays in the big leagues, and every so often, simply flattens the competition… all of it! The Platinum P41 is now the fastest consumer M.2 SSD ever released. Powered by amazingly-fast NAND flash, and a proprietary controller that allows it to max out what the PCIe Gen 4 bus can deliver, it’s the one you want!
    The Guru’s Tip

    While the speed of this Gen 4 drive may be overkill in a gaming system, we figure you'll want it in this level of build!

  • Case

    Corsair iCUE 5000X RGB

    There’s simply no better case to use as a high-performance RGB showcase than the glass-covered 5000X from Corsair. It has four glass panels (front, top, and two sides), and includes three SP Elite RGB fans and a Node Core RGB controller pre-installed. Load it up with the additional gear we recommend in this guide and you will have an amazing performer and a system with looks that can’t be touched!
    The Guru’s Tip

    Corsair's iCUE software, which is what this case is named for, allows extensive control over RGB gear, including Corsair coolers, fans, RAM and peripherals, and even Asus motherboards like the one we recommend! Speaking of that board, we made sure to spec one with a Type-C header, so you can use this case's top-mounted USB Type-C port. Details matter, and we've got you covered!

  • Fan

    Corsair iCUE SP120 RGB Elite

    This fan will connect right up with the controllers built into the case, allowing it to sync both for RPM and lighting control with the stock fans.
    The Guru’s Tip

    In this build, you'll be mounting this fan in the rear of the chassis, where it will complement the three SP Elite front fans and the fans on the Corsair 360mm CPU cooler.

  • Power Supply

    Corsair RM850x (2021)

    Corsair is legendary in the PSU market, being among the first to develop truly-premium offerings. This 850W Gold-rated unit power supply is the latest in a long series of RM850x units, redesigned in 2021 for even better performance. It offers fully-modular cables, extreme efficiency and stability, and a magnetic levitation fan for low noise and long life!
    The Guru’s Tip

    This model is fully-compatible with the slick individually-sleeved cables listed in our optional products section below, which will give your system a truly custom look!

  • CPU Cooler

    Corsair iCUE H150i Elite LCD CPU Cooler

    Corsair’s H150i Elite LCD offers more performance and features than any other 360mm cooler. Its big radiator is equipped with triple ML120 RGB Elite fans, which offer a great balance of performance and noise, and its pump has an awesome built-in LCD display, allowing you to monitor just about anything in your PC using the Corsair iCUE software.
    The Guru’s Tip

    This cooler includes the socket 1700 adapter required for the 12th-Gen Intel CPU we recommend.

  • Operating System

    Windows 11 Home USB

    Windows 11 take everything people loved about Windows 10, and then takes it to 11! It adds significant under-the-hood changes to make it faster and more secure, and of course, the interface is sleek too!
    The Guru’s Tip

    This is absolutely the OS you want on your system to take full advantage of the Intel 12th-Gen CPU!

Optional Products

  • Cable

    Corsair Individually Sleeved PSU Cables Pro Kit – White

    These sleek individually-sleeved cables provide the ultimate custom look for your PC! While we love white, they are available in a wide variety of colors, all on the same product page.
    The Guru’s Tip

    The kit includes all the cables you'll need for this build and then some! Note that they sell out constantly and are completely optional, so you can always pick them up later on.

  • The Mechanical Gaming Keyboard

    Corsair K70 RGB MK.2 Rapidfire

    The Corsair K70 set the standard for mechanical gaming keyboards and is still the benchmark by which all others are judged. With its solid aluminum construction and detachable wrist rest, it’s a truly premium option. And for the very fastest gameplay, there’s nothing better than the Rapidfire version, which uses Cherry’s unbeaten MX Speed switches. Their short throw give you amazing response and feel.
    The Guru’s Tip

    This board will look great paired up with an RGB rig!

  • Mouse

    Corsair Dark Core RGB Pro SE

    Offering up awesome functionality, a sleek design, and an ultra-fast 18,000 DPI sensor, the Dark Core Pro simply has no competition at its pricepoint. This “SE” version can be easily charged with an Qi-compatible charging pad!
    The Guru’s Tip

    Sync the mouse's lighting using the Corsair iCUE software!

  • The Deluxe PC Headset

    Corsair Virtuoso Wireless Headset

    Combining ultra-high-end performance with incredible comfort, this wireless headset from Corsair is the ideal all-day companion for listening to the latest market news.

  • The 32" 4K 144Hz Gamer's Dream Monitor

    Gigabyte M32U

    It took seemingly forever for the elusive 32″ 4K 144Hz panels that gamers had dreamed of for years to finally hit the market, and surprisingly Gigabyte was first out of the gate with one widely available at retail. Known for its high-end video cards and motherboards, Gigabyte has quickly made a name for itself in the gaming monitor market, and the M32U simply astounds with its features. Get a load of these specs: a 31.5″ 3840 x 2160 4K IPS panel, 144Hz refresh rate, 1ms (GTG) response time, FreeSync, 10-bit color,  90% DCI-P3  and 123% sRGB color space, and VESA DisplayHDR 400. It even has a built-in KVM switch, allowing you to use it on multiple systems with the push of a button!
    The Guru’s Tip

    There's no better way to show off brutal gaming horsepower than with a big 4K monitor!
