Build a PC / office & everyday

$9,000 office PC, part by part

An Intel Core Ultra 7 270K Plus with the GeForce RTX 5090, and the 6 parts around them that fit it: $8,419 all in.

A desk that never stutters: browser, documents, calls and 1080p video, on two or three screens. Every part here was checked against every other for fit, and picked for snappy single-core speed, quiet running, and a card that drives two or three screens without fuss. 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.

Everything past this costs far more than the speed it adds, so the build stops at $7,978 rather than spend the rest of the budget on a bigger number. $1,022 is left for a screen, a keyboard and a mouse.

The Intel Core Ultra 7 270K Plus and the GeForce RTX 5090 are well matched at 1080p.

The Intel Core Ultra 7 270K Plus drops into the LGA1851 socket, lever down: 24 cores, up to 5.5 GHz.

The Arctic Liquid Freezer III Pro 360's block sits on the chip and its 360 mm radiator bolts to the roof; rated 330 W against 250 W.

Two sticks of G.Skill Trident Z5 RGB 32GB (2x16GB) DDR5-6400 CL32 click into the second and fourth slots: 32 GB at 6400 MT/s.

The Crucial T705 4TB screws into the first M.2 slot, the WD Black SN8100 4TB into the second.

The GeForce RTX 5090 slides into the x16 slot and latches: 330 mm in a case that takes 422 mm, 32 GB of memory.

The Corsair HX1500i (2023) goes into the basement, 1500 W for a build that draws about 1100 W flat out, one native 16-pin cable to the card.
