Corsair One Pro

Introduction, Design Features

2012 Editors' Choice Logo

Corsair is a name code that frequently graces Computer Shopper’s home page. The U.S.-based association produces top-quality peripherals (notably, gaming keyboards and mice), as good as a outrageous operation of PC components: energy supplies, memory (RAM), storage, liquid-cooling gear, and desktop cases. And that’s to name customarily some of a categories it is in.

Add full-on PCs to that checklist. Corsair creates roughly any partial essential to building or upgrading your desktop PC, so it was customarily a matter of time before a association started rolling a own. The One Pro desktop you’re looking during subsequent is Corsair’s initial incursion into a pre-built PC market, and it’s a hit. This small-form-factor (SFF) desktop is prepared to diversion out of a box. You customarily need to supplement a guard (or two), peripherals, and, of course, games.

Corsair One Pro (Left Angled)

As we would expect, a One Pro has a resources of Corsair goodies inside, including Corsair dual-channel RAM, a Corsair SF400 energy supply, a Corsair Force LE solid-state-drive (SSD), and liquid-cooling solutions for both a CPU and the graphics card. Liquid cooling for graphics is a underline frequency seen, even aftermarket, in anything detached from pricey boutique-built PCs.

Corsair is positioning a One Pro as a high-end PC that’s compress and quiet. The high-end partial is reliable by a price; during $1,799 for a bottom indication (called customarily “Corsair One,” nonetheless a “Pro”), and $2,299 for a One Pro indication we tested, it’s not accurately container change for many of us. However, going off a specifications alone, a pricing appears to be really reasonable for what’s included. Our examination section was installed with a latest Intel Core i7-7700K “Kaby Lake”Nvidia GeForce GTX 1080 video card, 16GB of RAM, a 960GB SSD for storage, and a two-year warranty.

We mock-built an Origin ChronosAlienware Aurora R5GeForce GTX 1080 Ti for a same cost that competitors are charging for a matching settlement with a customary GTX 1080. Corsair is really going into a gaming-PC marketplace with dual guns blazing.

Fun pricing contribution aside, though, this wouldn’t be many of a examination unless we found something we didn’t like, and we did find a few quirks with a One Pro. Overall, though, Corsair has done a worthy bid with a initial PC, generally deliberation how compress and parsimonious a settlement is.


We favourite a Corsair One Pro before we even incited it on. Its all-black, all-metal extraneous is vault-like in a construction. Just about all on a extraneous is aluminum, including a finned cooling abrade during a top. The bottom of a box also has a matching finned design, nonetheless it’s one plain piece. On a underside, a vast round square of rubber keeps a One Pro resolutely in place.

The One Pro is 15 inches tall, 7 inches wide, and somewhat deeper than it is wide, during 7.9 inches front to back. The box has a sum volume of 12 liters, definitively classifying it as an SFF tower. Consider that a gaming mid-tower desktop, such as a Lenovo IdeaCentre Y900 Razer EditionMSI Trident. However, if we wish a full-power desktop components that are inside a One Pro, you’re not expected to find them in a package many some-more compress than this one.

Keep in mind that a One Pro can customarily be oriented station up, as we see in a photos. You won’t be means to fit it inside many TV cabinets, nonetheless with it looking as good as it does, it’d be a contrition to censor it, anyway.

Corsair One Pro (Front)

The dual lightning-bolt-like lines flanking a front of a framework we see above are a box lighting. The liughtness is controllable in really tiny increments in a pre-installed Corsair Link software; relocating a slider all a approach to a left turns a lighting off. A respirating settlement is available, nonetheless zero else.

We do have to demonstrate a amiable bewail that a box lighting is accessible customarily in a light sky-blue color. Corsair says it chose this tone to compare a cultured of a PC. We determine a tone it chose looks great, nonetheless we don’t cruise any opposite tone would have done this PC demeanour any reduction elegant.

The front-mounted ports are singular to a USB Type-A 3.0 port, and an HDMI output. The latter competence seem a extraordinary thing to be there, until we comprehend that it is meant for hooking adult VR headsets…

Corsair One Pro (Front Ports)`

Indeed, Corsair went above and over with that front HDMI port. The few desktops we’ve tested so distant that have had front-mounted HDMI ports compulsory us to bond a mini-HDMI-to-HDMI cable, from a video label to a pass-through HDMI port, that would track a vigilance to a front HDMI port. (See a MSI Aegis 3, as an example.) With a One Pro, there’s no need to do that; a front HDMI pier is active during all times.

Also on a front of a desktop is a rectilinear energy button, directly above a ports. It isn’t illuminated, a probable and if you’re formulation to nap with a One Pro using in your room. Two things we would have appreciated adult front are a headphone/microphone jack, and a flash-card reader. You’ll have to strech around a behind for a former, nonetheless there’s no flash-card reader anywhere on this unit.

The remaining ports are on a behind of a desktop, nearby a bottom…

Corsair One Pro (Back)

To a reduce right you’ll find a AC connector, and customarily above that, a second HDMI port, and dual DisplayPort connectors. Like a front HDMI port, these video-out ports are specifically routed here. You competence notice that a space they occupy doesn’t demeanour like a common behind of a video card. (It’s not.)

Corsair One Pro (Back Ports)

The MSI Z270 Mini-ITX motherboard in a One Pro provides a serviceable volume of connectivity. A contingent of USB Type-A 3.1 ports sits in a center, giving a singular USB Type-C 3.1 pier some company. Above them is a Clear CMOS button, a useful underline if you’re into overclocking, and finish adult with a wrong settings; dire this symbol puts all behind to default, so we can start tweaking afresh.

Two wireless-antenna connectors are subsequent to a CMOS button. A span of antennas, enclosed in a box, screws in with minimal effort. You contingency use a antennas for a One Pro to grasp serviceable wireless range. They extend an in. out a back, and afterwards about 4.5 inches upward. They’re not manifest from a front of a One Pro, unless, of course, we indicate them out toward a sides like a span of insect feelers. Realistically, we’d like to see a wireless receiver built into a chassis, nonetheless we think a all-metal extraneous of this appurtenance isn’t in a mood to concur with that request.

The audio connectors during a tip of a motherboard embody headphone and microphone jacks, left and right approximate connectors, line-in, and S/PDIF (optical) out. For your bequest devices, there are dual USB Type-A 2.0 ports, and a PS/2 pier during a bottom.


Corsair sells a handful of opposite configurations of a One; it’s not factory-configurable down to a member level. As we were essay this examination in late Apr 2017, many of a differences among a accessible models were associated to a storage drives and a video card.

A 16GB set of DDR4-2400 dual-channel memory is customary opposite configurations. The bottom $1,799 indication (“Corsair One”) gets we a Core i7-7700 non-“K” quad-core CPU, an air-cooled GeForce GTX 1070 video card, and a 240GB SSD/1TB tough expostulate storage combo. Our $2,299 One Pro settlement bumped adult to a Core i7-7700K CPU and a faster GeForce GTX 1080 video card, interconnected with one vast 960GB SSD and no tough drive. The many costly ($2,599) indication was configured a same as a model, nonetheless serve upped a graphics label to a GeForce GTX 1080 Ti. (Corsair records that this is a Web-store disdainful version, and calls it a “Corsair One Ti.”) Note that configurations with a GTX 1080 or GTX 1080 Ti embody glass cooling on a GPU, given a GTX 1070 in a bottom indication is customarily supposing as air-cooled.

As we mentioned in a examination intro, Corsair’s pricing for these specifications is aggressive. It’s several hundred reduction than we could find in a competing desktop, even when looking during mid-towers, in that a space and labor constraints would seem reduction strict. We think Corsair has taken advantage of a new cost dump on a GeForce GTX 1080; as we noted, we can get a One Pro with a GTX 1080 Ti for what competitors are charging for a customary GTX 1080. (Sourcing a possess tools for many of a inner pieces is expected another efficiency.)

Corsair One Pro (Components)

We were dismayed, though, to find out that end-user upgrades on a Corsair One Pro will blank a warranty. You can open a sides of a desktop to gawk on a interior, nonetheless that’s all. Upgrading even simple components, such as memory and storage, is a no-no. Corsair pronounced it’s formulation to offer an ascent service, nonetheless a sum of a module weren’t nonetheless accessible as we wrote this. The ascent use is something to consider, we suppose, nonetheless even many gaming notebooks concede we to ascent simple components, and this is a desktop we’re articulate about. That said, a configurations of a One Pro accessible leave we tiny we competence want to ascent for some time to come.

The one partial of a desktop that comes off simply is a tip finned grate, trustworthy to that is a 140mm fan. Pressing a symbol during a behind of a desktop pops a abrade free. Don’t mislay it too fast, as a fan is connected around a energy cable. Under this grate, we can see a behind of a Corsair SF400 energy supply, and a tops of a dual 240mm glass cooling radiators that line any side panel…

But we can’t see anything else inside a framework from here.

Before we go any further with this exploration, we’d like to go on record: We don’t suggest perplexing any of what we’re about to describe. The side panels are any hold on by dual Phillips-head screws, manifest after stealing a finned grate. Getting out these screws is a plea in itself, as your screwdriver will need to be during an angle to insert into a heads of a screws. Once a screws are removed, a panels lift adult from, nonetheless not giveaway of, a chassis. The liquid-cooling radiators are mounted to a side panels, and their hoses keep them on a brief leash. You can’t lift a side panels some-more than a few inches away.

The interior of a framework is easily blacked out. It’s chock full of cables, nonetheless they’re orderly tied off and routed. Interior classification wouldn’t seem to matter all that much, given a One Pro’s interior is invisible unless we take a desktop apart, nonetheless it does uncover that Corsair doesn’t leave tiny sum to chance, and it has optimized for what airflow there is.

The interior is divided down a center into dual straight chambers. The liquid-cooled Nvidia GeForce GTX 1080 setup dominates a left chamber. Up to 11-inch GPUs will fit, but, as we can see below, a whole cooling intrigue is a really custom-fit affair…

Corsair One Pro (Open Left)

The MSI Z270 Mini-ITX motherboard, meanwhile, is partly manifest behind a right side panel. As with a left side panel, a right side row doesn’t come totally off; an matching liquid-cooling radiator abides over here, a hoses bending adult to a CPU waterblock…

Corsair One Pro (Open Right)

We could customarily see a dual 288-pin DIMM slots for desktop memory inside. Each was populated with an 8GB hang of Corsair-brand DDR4-2400, creation for a sum of 16GB of RAM using in dual-channel. Up to 32GB of RAM, in a two-16GB-DIMM setup, is supported. A 2.5-inch brook is also manifest underneath a right side panel, above a RAM. (The One Pro indeed has dual 2.5-inch bays, nonetheless we weren’t wholly certain where a other one was located.) It’s distinct that a 3.5-inch brook wouldn’t fit in these confines. There’s also an M.2 container on a underside of a motherboard.

The miss of end-user upgradability in a One Pro isn’t a finish of a world. The CPU and RAM in a accessible configurations will be good adequate for gaming for some time; it’s a GPU that customarily needs to be upgraded first. We’ll be meddlesome to see what Corsair’s ascent module looks like.


As we remarkable in a prior integrate of paragraphs, a One Pro is sole with opposite cooling setups, depending on a configuration. Our examination section had glass cooling on both a CPU and video card, nonetheless a bottom indication has glass cooling on a CPU only. However, that doesn’t change how a airflow in a complement works.

Air is drawn in primarily through a seperated side panels in a chassis. The disastrous vigour compulsory to make this probable is pleasantness of a vast 140mm fan during a tip of a desktop, that pushes atmosphere directly upward…

Corsair One Pro (Top)

The atmosphere drawn in by a side panels passes by a liquid-cooling radiators first. The One Pro’s design, then, is radically like an industrial cooling tower. The proof creates finish clarity to us, and, as we’ll fact momentarily, it was effective during gripping a One Pro cool.

But before we speak about how cold a thermal fortitude kept a inner components, let’s plead a sound level. This isn’t a wordless PC, as it does have fans, nonetheless it’s about as still of a gaming PC as you’re expected to find. We had to put a ears right adult to a One Pro to hear it for many tasks. For gaming, a fans apparently have to pierce faster, nonetheless they emanate no engine sound or whine. All you’ll hear is a still transformation of atmosphere by a tip grate. That’s presumption there’s no credentials noise; this is one still PC indeed.

To give a One Pro a genuine workout, we ran Rise of a Tomb Raider during a 4K fortitude for 30 minutes. In a room that was 72 degrees F, we available a Core i7-7700K commanding out during customarily 71 degrees C, and a GeForce GTX 1080 during an even cooler 62 degrees C. In a customary air-cooled GTX 1080 Founders Edition guise, a GeForce GTX 1080 customarily tops out in a mid-80-degree C operation when underneath stress, that should give we an thought of how many a glass cooling helps. Although a One Pro has no built-in overclocking facilities for possibly a CPU or GPU, a glass cooling positively provides adequate thermal headroom to make it possible. The Core i7-7700K chip in a examination section had unbarred multipliers, and a BIOS of a MSI Z270 motherboard was open to tinkering, and not sealed down, as it typically would be from a mainstream PC maker.
