How Much Does a Desktop PC Weigh? (Plus Laptop Weights)
A desktop PC generally weighs as much as 15 to 35 pounds, with the case, power supply and graphics card making up most of that total. Budget towers land near 20 pounds, mid-range builds run about 27 pounds, and high-end or full-tower gaming rigs often reach 35 pounds or more. Compact mini-ITX builds can weigh as little as 10 pounds, while water-cooled showcase systems climb past 60 pounds. All-in-one desktops, which combine the screen and the computer in a single unit, usually fall between 12 and 20 pounds. Laptops sit in a lighter class altogether, ranging from about 2.5 to 5.5 pounds for mainstream models and up to 9 pounds or more for gaming laptops.
How Much Does a Desktop PC Weigh
Desktop weight depends mostly on case size, ranging from about 10 pounds for a compact mini-ITX build to 60 pounds or more for a full tower packed with water cooling. Case type, form factor and the parts installed inside determine the exact number.
Weight by Case Size
Case size is the biggest single driver of desktop weight. Budget cases weigh approximately 20 pounds (9 kilograms), mid-range cases run about 27 pounds (12.2 kilograms), and high-end cases reach roughly 35 pounds (15.8 kilograms), according to Tech4Gamers. A fully loaded high-performance gaming PC can weigh as much as 80 pounds (36 kilograms) once every component is installed.
Weight by Form Factor
Form factor narrows the range further, since each chassis style uses a different amount of steel and glass. The Tools Trunk breaks typical weights down by form factor as shown below.
| Form Factor | Typical Weight |
|---|---|
| Mini-ITX | 10 to 22 pounds |
| Micro-ATX | 18 to 30 pounds |
| Mid-tower | 22 to 38 pounds |
| Full-tower | 35 to 60 pounds |
| Water-cooled showcase build | 45 to 80 pounds |
How Much Does an All-in-One Desktop Weigh
An all-in-one desktop typically weighs between 12 and 20 pounds (5.4 to 9 kilograms), since the screen, motherboard and power supply share one slim enclosure, according to PCGlance. That range sits well below any tower case, yet above every laptop on the market.
Buyers who need to move a computer between rooms often choose an all-in-one for that middle ground, trading upgrade room for a single lighter unit with no separate monitor to carry. A mid-tower desktop can outweigh the same all-in-one by more than 10 pounds once a dedicated graphics card and a larger power supply are added.
What Do These Weight Numbers Include
Tower and laptop weight figures describe the tower or the laptop body itself, not any accessories that ship alongside it. A desktop’s weight excludes the monitor, keyboard, mouse and speakers, since each of those parts is sold, boxed and weighed on its own. Laptop makers can also leave the charger out of the listed figure, so the total inside a shipping box usually runs higher than the number on a spec sheet.
Packaging adds further weight on top of the product itself. Foam inserts, cardboard and any included cables mean a retailer’s shipping estimate is often somewhat heavier than the manufacturer’s stated product weight, which is the figure most spec sheets and reviews quote.
How Much Does a Laptop Weigh
A laptop weighs far less than a desktop, typically 2.5 to 5.5 pounds (1.1 to 2.5 kilograms) for a mainstream 13 to 15 inch model, according to DevicePicks. Ultraportable notebooks start around 1.5 pounds, and gaming or workstation laptops can pass 9 pounds. Weight differences this large explain why most people carry a laptop daily and reserve a desktop for a fixed workspace.
Weight by Screen Size
Screen size predicts laptop weight closely, since a larger display needs a bigger frame, a larger battery and more cooling hardware. DevicePicks breaks the ranges down by screen size as follows.
| Screen Size | Weight Range |
|---|---|
| 11 to 12 inches | 1.8 to 3.0 pounds |
| 13 to 14 inches | 2.2 to 4.0 pounds |
| 15 inches | 3.5 to 5.5 pounds |
| 16 to 17 inches | 4.5 to 8.5 pounds |
Weight by Portability Type
Laptop makers also group models by intended use rather than screen size alone. Pigtou and PCGlance both describe four rough tiers: ultra-lightweight models under 2 pounds built for portability, lightweight models between 2 and 4 pounds, mid-weight models between 4 and 6 pounds for heavier workloads, and gaming or workstation laptops above 5.5 pounds built as desktop replacements. Popular thin-and-light models such as the MacBook Air and Dell XPS 13 weigh under 2.8 pounds.
What Factors Affect a Desktop PC’s Weight
Six parts account for nearly all of a desktop’s weight: the case, the graphics card, the power supply, the CPU cooler, the motherboard and the storage drives. The case alone represents roughly one third of the finished weight, and an empty mid-tower case weighs 15 to 22 pounds before any parts go inside, according to The Tools Trunk.
- Case: about one third of total weight; an empty mid-tower case runs 15 to 22 pounds
- Graphics card: large cards add 0.4 to 3.3 pounds
- Power supply: adds 2.5 to 5 pounds because of internal transformer parts
- CPU cooler: large air coolers add 1 to 3 pounds; liquid coolers add 2 to 5 pounds
- Motherboard: weighs 1 to 3.3 pounds
- Storage: each hard drive adds 1 to 2 pounds; solid-state drives weigh less
Tempered glass side panels, a common upgrade on gaming cases, add noticeably more weight than mesh panels. Two builds using the same case can still differ by several pounds once cooling choices and drive count are factored in.
How to Estimate the Weight of a Desktop You Already Own
The fastest way to estimate a desktop’s weight without a scale is to match its case size to the ranges above, then adjust upward for extra drives, liquid cooling or a second graphics card. Five quick steps cover most builds.
- Identify the case form factor, mini-ITX, micro-ATX, mid-tower or full-tower, from the box or the spec sheet.
- Start with that form factor’s typical weight range from the table above.
- Add 2.5 to 5 pounds if the build uses a high-wattage power supply.
- Add 1 to 3.3 pounds for a large graphics card.
- Move toward the top of the range if the case has tempered glass panels, a liquid cooling loop, or more than two storage drives.
Owners who want an exact figure rather than an estimate can weigh the tower on a bathroom scale by stepping on it while holding the case, then subtracting their own weight. That method works for any case too heavy to lift onto a kitchen scale.
Checking a laptop’s own weight is simpler, since most manufacturers print the figure on the spec sheet or the box. When that number is missing, the screen size and portability tables above give a close estimate without any measuring at all.
The refurbished Lenovo ThinkPad T14 Gen 2 I have had since 2022 is a reminder that a laptop’s listed weight is the easy version of this problem. For a desktop tower, I would step on a bathroom scale holding it and subtract my own weight, because my mental arithmetic is already carrying enough weight.
Example: Adding up the Weight of a Mid-Tower Gaming PC
Adding the typical weight of each part shows how a mid-tower gaming PC reaches roughly 30 pounds fully assembled. Starting from an empty mid-tower case, a full build adds up quickly, as the list below shows.
- Power supply unit: 4 pounds
- Graphics card: 3 pounds
- CPU air cooler: 2 pounds
- Motherboard: 2 pounds
- Total: about 30.5 pounds
That total lands squarely inside the 22 to 38 pound mid-tower range reported by The Tools Trunk, which explains why most finished gaming PCs weigh close to 30 pounds rather than the lighter empty-case figure alone.
A Heavier Full-Tower Example
Swapping in a full-tower case, a second graphics card slot filled with a larger cooler, and a liquid cooling loop pushes the same build well past 30 pounds. A full tower on its own already starts at 35 pounds before any liquid cooling parts go in, and The Tools Trunk places water-cooled showcase builds at 45 to 80 pounds once everything is installed. Two extra hard drives, a beefier power supply and thicker tempered glass panels are usually enough to cross into that heavier range.
What Factors Affect a Laptop’s Weight
Bigger screens need heavier glass and a sturdier frame, and larger batteries add weight in exchange for longer runtime, according to Pigtou. Manufacturers balance these factors differently, which is why two laptops with the same screen size can still land a half pound or more apart on a scale.
- Screen size: larger displays need bigger frames and heavier glass panels
- Battery capacity: a larger battery adds weight but extends runtime
- Build material: aluminum, magnesium alloy and carbon fiber weigh less than plastic
- Cooling system: gaming and workstation laptops carry extra fans and heat pipes
- Touchscreen: the added digitizer layer adds a small amount of weight
Desktop vs Laptop Weight at a Glance
Desktop PCs outweigh laptops by a wide margin in every category, from the smallest all-in-one to the heaviest full tower. The table below lines up every common type side by side for quick comparison.
| Type | Typical Weight |
|---|---|
| Ultraportable laptop | 1.5 to 3 pounds |
| Mainstream 13 to 15 inch laptop | 2.5 to 5.5 pounds |
| Gaming or workstation laptop | 5.5 to 9+ pounds |
| All-in-one desktop | 12 to 20 pounds |
| Mini-ITX desktop | 10 to 22 pounds |
| Mid-tower desktop | 22 to 38 pounds |
| Full-tower desktop | 35 to 60 pounds |
A mainstream laptop weighs roughly one fifth of a full-tower desktop, which is why travelers default to laptops and gamers who stay in one spot often prefer the larger case for better cooling and easier upgrades.
Frequently Asked Questions
Is a Desktop PC Heavier than a Laptop?
Yes, a desktop PC is always heavier than a laptop of similar performance. Even a compact mini-ITX build starting near 10 pounds outweighs most gaming laptops, and a full tower can weigh six to eight times as much as a mainstream notebook. The gap comes from the case, power supply and cooling hardware that a laptop simply does not carry.
Does a Bigger Case Always Mean a Heavier PC?
Usually yes, since a bigger case holds a bigger power supply, more drive bays and often a larger cooling setup. A full tower in the 35 to 60 pound range typically weighs close to twice as much as a mini-ITX build in the 10 to 22 pound range. The exception is a small case stuffed with a liquid cooling loop, which can outweigh a larger air-cooled build.
Why Do Gaming Laptops Weigh More than Regular Laptops?
Gaming laptops weigh more because they pack in bigger batteries, larger cooling systems and higher-power components than a mainstream notebook needs. Pigtou notes that elaborate cooling hardware alone adds noticeable weight in gaming and workstation models. That extra hardware is why gaming laptops commonly reach 5.5 to 9 pounds or more.
How Much Does an Empty PC Case Weigh?
An empty mid-tower case weighs about 15 to 22 pounds on its own, according to The Tools Trunk. Smaller mini-ITX cases weigh less, and full-tower cases built for multiple drives and radiators weigh more before any components are installed.
Which Laptops Weigh the Least?
Ultraportable and thin-and-light laptops weigh the least, generally 1.5 to 3 pounds according to DevicePicks and Pigtou. These models trade a larger battery and extra ports for a lighter magnesium alloy or carbon fiber chassis, so they suit travel better than heavy workloads.
How Much Does a Power Supply Add to a Desktop’s Weight?
A power supply adds 2.5 to 5 pounds to a desktop build, mostly from its internal transformer and metal casing, according to Tech4Gamers. Higher-wattage units with larger transformers sit at the heavy end of that range. That share matters more in a small mini-ITX build than in a full tower, where it is a smaller slice of a much bigger total.
Case size sets the baseline for any desktop, and the parts installed inside push the final number up from there. A laptop buyer choosing by weight alone should look at screen size and chassis material first, since those two factors matter more than brand. Shoppers comparing several models at once get the clearest picture by lining up case size or screen size next to the ranges above.
