Wireless mice get most of the 8,000 Hz headlines. The Endgame Gear OP1 8K V2 takes the other route: a cable, no battery, and 8,000 Hz polling set as the default.
This page is a research-based analysis. GameVexo has not handled this mouse. The facts below come from Endgame Gear’s product page, a retailer copy of its spec sheet, and independent tests by RTINGS and TechPowerUp, each named where it is used. The page covers what 8K polling asks of your PC, what changed from the first OP1 8K, and who should look at something else.
The Endgame Gear OP1 8K V2 is a wired, 49.5 g mouse with polling rates up to 8,000 Hz, so it suits players with a capable CPU and a good USB port, and it has no battery or wireless mode (the wireless version is the OP1w 4K V2, limited to 4,000 Hz).
The short verdict
Based on the published specifications, the Endgame Gear OP1 8K V2 is aimed at competitive shooter players who want a light, wired mouse for a claw grip and who have a PC and monitor that can use high polling rates. It is a poor match if you want wireless, a large shell for a palm grip, or a long list of buttons.
Three published facts frame everything else. Endgame Gear lists the weight at 49.5 g. The polling options are 1,000, 2,000, 4,000 and 8,000 Hz, with 8,000 Hz as the default. The connection is a 1.8 m USB cable. GameVexo has not tested any of this, so read the page as a careful reading of the spec sheet.
What changed from the first OP1 8K
RTINGS compared the V2 with the original OP1 8K. It reports the same shape and switches, and says the internal changes bring no measurable or noticeable performance gain. Here is what differs on paper.

|---|---|---|---|
| Sensor | PixArt PAW3395 | Custom PixArt PAW3950 | Retailer copies of Endgame Gear spec sheets |
| Weight | 50.5 g | 49.5 g | Retailer copies of Endgame Gear spec sheets |
| Max tracking speed | 650 IPS | 750 IPS | V1: retailer listings. V2: Endgame Gear |
| Microcontroller | Older (model not confirmed) | Nuvoton M483 | Endgame Gear; RTINGS notes a new MCU |

Endgame Gear OP1 8K V2
Wired, 49.5 g, polling up to 8,000 Hz (manufacturer specifications)
Endgame Gear built the OP1 8K V2 around low weight, an 8,000 Hz default and a shape aimed at claw grip. On paper it is a small update to the first OP1 8K: a newer sensor, controller and scroll encoder, with the same shell and switches. Whether 8K is worth running depends on your PC, as section 3 explains. GameVexo has not handled this mouse, and everything here rests on published specifications.
- Low listed weight of 49.5 g
- 8,000 Hz default, with 1,000, 2,000 and 4,000 Hz options
- No battery, so no runtime cost at high polling
- Swappable Kailh GX main switches, per the spec sheet
- Wired only
- Shape is aimed at claw grip; palm-grip players with large hands may want a bigger shell
- 8K needs a capable CPU and a good USB port, and Endgame Gear publishes no minimums
- The official page lists conflicting CPI and lift-off figures
Based on the specifications, this is a sensible wired option for competitive shooter players with a modern PC who prefer a claw grip. It is a weak fit if you want wireless or many buttons. Owners of the first OP1 8K have little reason to switch, according to RTINGS.
Weight, as specified
Endgame Gear lists the OP1 8K V2 at 49.5 g. Every weight on this page is a manufacturer or retailer figure, not a GameVexo measurement. A retailer spec table shows about 49.5 g for the Black and White versions and about 50.5 g for Dark Frost, so the colour you buy may shift the figure by a gram.
The first OP1 8K is listed at 50.5 g, which makes the V2 about 1 g lighter on paper. GameVexo cannot say whether anyone would feel 1 g. Treat it as a spec-sheet gap, not a performance claim.
The listings do not say whether the 1.8 m cable is counted in the figure. Endgame Gear says the Flex Cord 5.0 in the box is designed to reduce cable drag, which matters more for feel than a gram does. For other weights side by side, see the table in section 7.
8K polling: what it needs from your PC
Short answer: a cable, a CPU with headroom, a good USB port and a fast display. The mouse itself only asks for the cable. Endgame Gear’s product page lists a USB 2.0 Type-A connection and ships the mouse at 8,000 Hz. It publishes no minimum CPU, USB controller or monitor spec, and no separate manual that does turned up in our research. The practical guidance below comes from independent testers and is labeled as theirs.
What polling rate means
Polling rate is how many times per second the mouse reports to the PC. At 1,000 Hz that is one report every 1 ms. At 8,000 Hz it is one every 0.125 ms. Your PC has to receive and process eight times as many reports, and that is where the CPU and USB demands come from.
What Endgame Gear documents
The product page lists polling rates of 1,000, 2,000, 4,000 and 8,000 Hz, with 8,000 Hz as the default. A mode button cycles the rates, and Endgame Gear notes that game and operating-system support for high polling is still developing. The page also says the mouse has no power-saving features, and that click polling stays at 8,000 Hz whatever the sensor rate is set to.
Motion Sync is available up to 8,000 Hz at the cost of one polling event of delay. One event is 0.125 ms at 8,000 Hz, against 1 ms at 1,000 Hz (GameVexo arithmetic). Endgame Gear also states an average click latency below 70 microseconds from its own XLAT testing. That is a manufacturer claim and has not been independently confirmed.
What independent testers add
TechPowerUp’s review of the OP1 8K V2 recommends a USB 3.x port running in XHCI mode, and notes that ports forced into EHCI behave like native USB 2.0. It also advises a strong CPU and a 240 Hz or 360 Hz display, and warns that weaker CPUs may respond worse at high polling because of the extra load.
In its review of the same maker’s XM2 8K, TechPowerUp suggests at least six physical cores with high IPC, a USB port native to the CPU, and no other high-polling devices on the same hub. It also says 8,000 Hz needs at least 8,000 pixels of motion per second. That last point is easy to miss, so the second table below turns it into hand speed.
The first table maps each requirement of an 8K setup to the source that states it. The second converts TechPowerUp’s motion figure into hand speed, using CPI presets of 400, 800, 1,600 and 3,200 as listed by Endgame Gear.
| Requirement | What the source says | Source / basis | Why it matters |
|---|---|---|---|
| Cable and port | USB 2.0 Type-A, 1.8 m cable | Endgame Gear | You need a Type-A port or an adapter plan |
| Polling options | 1,000, 2,000, 4,000, 8,000 Hz; 8,000 default | Endgame Gear | You can step down without new hardware |
| USB controller | USB 3.x port in XHCI mode | TechPowerUp (OP1 8K V2) | Controller mode can change how 8K behaves |
| CPU | Strong CPU; six physical cores suggested for 8K mice | TechPowerUp (OP1 8K V2, XM2 8K) | Weak CPUs may lose responsiveness |
| Display | 240 Hz or 360 Hz | TechPowerUp (OP1 8K V2) | Slower panels may not show the extra detail |
| Shared hubs | Avoid other high-polling devices on the same hub | TechPowerUp (XM2 8K) | Shared ports can limit 8K |
| Minimum PC spec | None published | Endgame Gear product page | Independent advice is the only guide |
| CPI setting | Hand speed for 8,000 counts per second | In centimeters | Basis |
|---|---|---|---|
| 400 | 20 in/s | 50.8 cm/s | GameVexo arithmetic |
| 800 | 10 in/s | 25.4 cm/s | GameVexo arithmetic |
| 1,600 | 5 in/s | 12.7 cm/s | GameVexo arithmetic |
| 3,200 | 2.5 in/s | 6.35 cm/s | GameVexo arithmetic |
How to read it: counts per second divided by CPI gives inches per second. This assumes one report needs at least one count of movement, as TechPowerUp’s pixel figure implies. At low CPI and slow aim, the mouse will report well below 8,000 Hz no matter what it is set to.
Shape and grip styles
Endgame Gear lists the OP1 8K V2 at 118.2 mm long, 60.5 mm wide and 37.2 mm high. It describes the shape as built for claw grip, with flatter sides and extended side walls meant to prevent accidental clicks. The PC Case Gear copy of the spec sheet adds that the mouse can suit palm grip with small hands and fingertip grip with larger hands. Treat these as the maker’s claims. GameVexo has not held this mouse, and shape is a personal fit.
RTINGS describes the V2 as symmetrical, while some retailers list it as right-handed. The software offers left-handed button remapping, according to the PC Case Gear spec sheet. A symmetrical shell does not guarantee side buttons on both sides, and the spec lists two side buttons, so left-handed players should check where they sit. Our best left-handed gaming mouse: 5 southpaw picks covers mice built for that hand, and the best ambidextrous gaming mouse: 5 symmetrical picks covers symmetrical shells.
If you want a bigger shell from the same maker, the XM2 8K V2 is listed at 122 × 66 × 38 mm. That is about 4 mm longer and 5.5 mm wider than the OP1.
Cable and battery: 8K without the battery cost
The OP1 8K V2 has no battery, so 8,000 Hz costs nothing in runtime. Endgame Gear says the mouse has no power-saving features. The trade is the cable: a 1.8 m Flex Cord 5.0 with a USB Type-A plug. If your PC only has USB-C ports, plan your adapter before buying. GameVexo has not verified 8K behavior through adapters.
Wireless 8K mice pay for polling in battery life. Razer lists the Viper V3 Pro at up to 95 hours at 1,000 Hz and 17 hours at 8,000 Hz, as reported by TechPowerUp. That is about 5.6 times shorter (GameVexo arithmetic). Endgame Gear’s wireless OP1w 4K V2 lists about 30 hours at 4,000 Hz and stops at 4,000 Hz.
Logitech’s G PRO X2 SUPERSTRIKE lists up to 8,000 Hz wirelessly but 1,000 Hz in wired mode, so plugging in a cable on that mouse lowers its ceiling. The OP1 8K V2 has no such split, because the cable is its only mode.
Who should skip it
Based on the specifications, skip the OP1 8K V2 if any of these describe you.
You want wireless
It is wired only. The OP1w 4K V2, Logitech G PRO X2 SUPERSTRIKE and Razer Viper V3 Pro are covered in section 7.
You need many buttons
The layout is short: two main buttons, two side buttons and a wheel. For mapping lots of actions, see our best mmo gaming mouse: 5 picks with real button counts.
You use a large palm grip
The shape is aimed at claw grip. A larger shell such as the XM2 8K V2 may fit better, though only holding one will tell you.
Your PC is older or your ports are shared
TechPowerUp warns that weaker CPUs may respond worse at high polling, and that shared hubs can limit it. You can still run 1,000 Hz, but then you are not using what the mouse is built around.
Your display is well below 240 Hz
TechPowerUp pairs 8K polling with 240 Hz or 360 Hz displays. On a slower panel the extra detail may be hard to see.
You already own the first OP1 8K
RTINGS reports the same shape and switches and no measurable or noticeable performance gain from the V2’s internal changes.
Alternatives worth considering
These four alternatives cover the gaps the OP1 8K V2 leaves: wireless, a larger shape and a different switch design. Figures are manufacturer or retailer specifications.

Endgame Gear OP1w 4K V2
The wireless route within the same family. At 59.5 g and 4,000 Hz it gives up 10 g and half the polling ceiling for no cable.
Endgame Gear XM2 8K V2
The larger wired option from the same maker, listed at 51.5 g. RTINGS describes the XM2 shape as bigger, with a broader back for palm support.
Logitech G PRO X2 SUPERSTRIKE
Wireless 8,000 Hz at about 61 g, using an inductive trigger system rather than conventional mechanical main switches. Wired mode is capped at 1,000 Hz.
Razer Viper V3 Pro
At 54 g it is light for a wireless mouse, but its listed 17 hours at 8,000 Hz is the battery cost described in section 5.
Evidence basis: This page is research-based. GameVexo has not handled the OP1 8K V2 or any alternative mentioned. Specifications come from manufacturer pages, retailer copies of those spec sheets, and independent tests. GameVexo’s own contribution is arithmetic on published numbers, always labeled as such.
What came from documentation: Weight, dimensions, polling options, connection, sensor and click-latency claims for the OP1 8K V2, OP1w 4K V2 and XM2 8K V2 come from Endgame Gear’s OP1 8K V2 page and its OP1w 4K V2 and XM2 8K V2 pages, plus the PC Case Gear copy of the spec sheet. Logitech figures come from Logitech’s product page and retailer listings.
Independent evidence: The V1 versus V2 comparison comes from RTINGS. PC requirements for 8K come from TechPowerUp’s reviews of the OP1 8K V2 and XM2 8K. Razer’s battery figures are as reported in TechPowerUp’s Viper V3 Pro review. These are third-party findings, not GameVexo measurements.
How alternatives were chosen: They were compared on connection, polling ceiling and weight, and picked to cover what the OP1 8K V2 does not: wireless, a larger shape and a different switch design.
