The Best $2000 Premium Mini-ITX Gaming PC Build

On the spec sheet, it offers a 96MB L3 cache and offers a 4.7GHz boost clock.

The Ryzen 5 7600X3D brings 6 cores and 12 threads, a 4.7GHz maximum boost, 96MB of L3 cache and a 65W rating, and it accounts for 12% of the parts total. It ships without a cooler, so the build pairs it with the IS-55. Its integrated graphics stay available as a backup display output.

The Ryzen 5 7600X3D uses the AM5 socket and the B850I Edge TI board uses AM5, so the processor seats in the board directly. Read the board's CPU support list for the BIOS version this chip needs. The Urbane V RGB is a DDR5 kit, the type both the B850I Edge TI (DDR5) and the Ryzen 5 7600X3D (DDR5) accept. A kit of the other generation would not physically fit the board. AM5 appears in the IS-55's supported sockets (AM5, AM4, LGA1851, LGA1700), so the bracket for the Ryzen 5 7600X3D comes in its box. A cheaper route is the Ryzen 5 7500F: 6 cores against 6, roughly 21% cheaper than the Ryzen 5 7600X3D; it keeps the same socket, memory type and cooler fit.

16GB of GDDR6, the RX 7800 XT chip, a 2.5-slot cooler, a 267mm length and 2 x 8-pin power come with the ASRock 7800 XT Challenger, which takes 27% of the parts total, more than any other part. For the supply, the maker's guidance for this chip is 750W.

The ASRock 7800 XT Challenger is listed at 267mm and the A3-mATX takes cards up to 415mm, which leaves 148mm before a front fan or radiator. The ASRock 7800 XT Challenger is an RX 7800 XT card, and its chip maker recommends a 750W system power supply. The Thermaltake Toughpower GT 1000W is 1000W, which leaves 250W for the processor, drives and fans. The ASRock 7800 XT Challenger lists 2 x 8-pin, and the Thermaltake Toughpower GT 1000W lists one 12V-2x6 connector, so match the cable to the card's socket. If the budget is tighter, the Arc B580 Challenger offers the Arc B580 with 12GB of GDDR6, against the RX 7800 XT's 16GB, roughly 39% cheaper than the ASRock 7800 XT Challenger; the supply wattage and case length rows stay green.

It also offers a 2 M.2 slot count and offers a 5Gbps wired network speed.

AM5 is the socket on the B850I Edge TI, a board with Mini-ITX size, 2 M.2 slots, Wi-Fi 7 and 5GbE LAN that accounts for 14% of the parts total; its memory slots accept DDR5 and nothing else.

The Urbane V RGB is a DDR5 kit, the type both the B850I Edge TI (DDR5) and the Ryzen 5 7600X3D (DDR5) accept. A kit of the other generation would not physically fit the board. The B850I Edge TI lists 2 M.2 slots, so the Optimus 5100 1TB has a home and a second drive can follow. The manual says which slot runs at full PCIe speed.

It also offers a CL30 CAS latency and offers a 6000MT/s rated speed.

This kit is 32GB, DDR5, 6000MT/s, CL30 and EXPO and XMP profiles in two sticks and takes 25% of the parts total, a heavy slice because DDR5 is expensive when we checked.

The Urbane V RGB is a DDR5 kit, the type both the B850I Edge TI (DDR5) and the Ryzen 5 7600X3D (DDR5) accept. A kit of the other generation would not physically fit the board. 32GB arrives as two sticks in the Urbane V RGB kit; the B850I Edge TI manual shows which two slots to fill so the memory runs in dual-channel. If the budget allows more, the Flare X5 64GB offers 64GB at 6000MT/s, roughly 134% dearer than the Urbane V RGB; it stays on the generation the board and processor take.

On the spec sheet, it is rated for 1TB.

The Optimus 5100 1TB offers 1TB and PCIe 4.0 and takes 9% of the parts total.

The B850I Edge TI lists 2 M.2 slots, so the Optimus 5100 1TB has a home and a second drive can follow. The manual says which slot runs at full PCIe speed. If the budget allows more, the P310 2TB offers 2TB on PCIe 4.0, roughly 35% dearer than the Optimus 5100 1TB; it uses the same M.2 slot as the current drive.

The Thermaltake Toughpower GT 1000W is 1000W, Gold rated, ATX 3.1, ATX format, fully modular cables and one 12V-2x6 connector and takes 5% of the parts total.

The ASRock 7800 XT Challenger is an RX 7800 XT card, and its chip maker recommends a 750W system power supply. The Thermaltake Toughpower GT 1000W is 1000W, which leaves 250W for the processor, drives and fans. The ASRock 7800 XT Challenger lists 2 x 8-pin, and the Thermaltake Toughpower GT 1000W lists one 12V-2x6 connector, so match the cable to the card's socket. The Thermaltake Toughpower GT 1000W is a ATX unit and the A3-mATX lists ATX, SFX or SFX-L, so the supply has a mount.

ATX, SFX and SFX-L units are all listed.

The A3-mATX lists room for mATX, ITX boards, graphics cards up to 415mm and a radiator up to 360mm and takes 5% of the parts total.

Mini-ITX is the B850I Edge TI's size, and the A3-mATX lists mATX, ITX, so the board has a place on its tray. The ASRock 7800 XT Challenger is listed at 267mm and the A3-mATX takes cards up to 415mm, which leaves 148mm before a front fan or radiator. The Thermaltake Toughpower GT 1000W is a ATX unit and the A3-mATX lists ATX, SFX or SFX-L, so the supply has a mount.

It fits cases too short for the 67mm to 70mm coolers.

The IS-55 is a tower air cooler with 5 heatpipes, a 120mm fan, 57mm height and AM5, AM4, LGA1851, LGA1700 mounting, and it takes 2% of the parts total.

AM5 appears in the IS-55's supported sockets (AM5, AM4, LGA1851, LGA1700), so the bracket for the Ryzen 5 7600X3D comes in its box. The IS-55 stands 57mm tall, but the A3-mATX listing gives no cooler height limit, so check the case page for that figure before ordering.
