Build a PC / heavy gaming

$6,500 4K gaming PC, part by part

An AMD Ryzen 7 9850X3D with the GeForce RTX 5090, and the 6 parts around them that fit it: $6,500 all in.

One of the three heavy targets at a time, and the result says which: 4K high settings by default, with ray tracing or 240 Hz at 1440p as the alternatives the same class of card serves. Every part here was checked against every other for fit, and picked for the strongest graphics card the budget allows. A price marked Amazon US is ScoutPrices' reading of the listing its button opens, dated; the rest are typical prices. Not a checkout total: no operating system, shipping, tax, screen, keyboard or mouse.

The AMD Ryzen 7 9850X3D and the GeForce RTX 5090 are well matched at 4K.

The ASRock B650M Pro RS WiFi goes onto the Montech Air 903 Max's tray: MATX, B650, nine standoffs.

The AMD Ryzen 7 9850X3D drops into the AM5 socket, lever down: 8 cores, up to 5.6 GHz.

The Thermalright Phantom Spirit 120 SE clamps onto the chip: a tower rated 260 W against the 162 W the chip can pull.

Two sticks of TeamGroup T-Force Delta RGB 32GB (2x16GB) DDR5-6000 CL30 click into the second and fourth slots: 32 GB at 6000 MT/s.

The Lexar NM790 2TB screws into the first M.2 slot under the card.

The GeForce RTX 5090 slides into the x16 slot and latches: 330 mm in a case that takes 400 mm, 32 GB of memory.

The Super Flower Leadex VII XG 1000W goes into the basement, 1000 W for a build that draws about 1000 W flat out, one native 16-pin cable to the card.

Side panel on, 4 case fans spinning. Fit for the job: 92 of 100.
