CARPE-X or BUZZ-X: 60g and 61g on the same Link 8K Receiver, two different shapes

Two mice, one receiver and almost the same footprint: the CARPE-X or BUZZ-X question comes down to a few millimetres and a single gram, which makes it harder than the spec sheet suggests. The Pulsar Pro Series CARPE-X Medium is listed at 60g, the Pulsar Pro Series BUZZ-X Medium at 61g, and both are symmetrical shells that pair with the Link 8K Receiver. What separates them is where each shell puts its length, its hump and its waist.

Quick Answer

Choose the Pulsar Pro Series CARPE-X if you want the longest shell in the Pro Series at 126 x 65 x 40.3mm, with a palm-and-claw hold. Choose the Pulsar Pro Series BUZZ-X if you prefer a slightly shorter 124.6 x 65.4 x 40mm shell with a low hump and a wide waist, listed for claw and palm. Weight will not settle it, because 60g and 61g each carry a plus or minus 2g tolerance. Evetech carries both inside its gaming mice range.

📏 Where the millimetres actually go

Put the two spec lines side by side and the gaps are small. CARPE-X measures 126mm long, 65mm wide and 40.3mm tall. BUZZ-X measures 124.6mm long, 65.4mm wide and 40mm tall. That is 1.4mm of extra length on CARPE-X, 0.4mm of extra width on BUZZ-X and 0.3mm of extra height on CARPE-X. No hand will feel 0.3mm, and most will not feel 0.4mm either.

The length gap is the one worth thinking about. A palm that runs the full back of the shell uses every millimetre it is given, and a longer body keeps the heel of the hand supported. CARPE-X is the longest mouse in the Pulsar Pro Series, so it is the natural pick for a hand that overhangs a shorter shell. BUZZ-X gives up 1.4mm and gains a shape that is more about contour than size.

What "symmetrical" means here

Both mice are symmetrical, so the left and right sides mirror each other and the shell is not built around one hand. That is a shape fact rather than a promise about comfort, but it is the reason either one can sit on a desk that two people share. The Pulsar Pro Series also includes Susanto-X and JV-X, and those two are a different conversation: Susanto-X is the shorter symmetrical shell at 118.7mm, and JV-X is an ergonomic palm shape at 121mm. CARPE-X and BUZZ-X are the larger pair.

The hump and the waist

BUZZ-X is described by Pulsar as having a low hump and a wide waist, aimed at control and stability in high-intensity play. A wide waist gives the thumb and ring finger something to press against, and a low hump keeps the back of the shell from pushing the palm upward. CARPE-X is described as a stable, slightly larger symmetrical shape, and its page does not claim a hump or waist at all, so the safest reading is a plainer, longer body.

🎯 Grip: one tagline each

Pulsar lists CARPE-X for palm and claw and BUZZ-X for claw and palm. The order is not accidental. Pulsar's one-line tagline for CARPE-X reads "built for palm grip", and the tagline for BUZZ-X reads "built for claw grip". Both mice accept both holds, but each one leads with a different one.

If your hand lies flat on the shell, with the whole palm touching the back, CARPE-X is the closer match. If your knuckles arch and the fingertips come down on the buttons, BUZZ-X with its low hump and wide waist asks less of that arch. A relaxed claw sits between the two, and either mouse can cope with it, so let the hand's length decide: a hand that reaches the end of a 126mm shell is a CARPE-X hand.

🔌 What the two have in common

Almost everything else is shared, and that is useful, because it removes variables from the decision.

• Sensor. Both use Pulsar's XS-1 flagship optical sensor, rated up to 32,000 DPI and 750 IPS, with DPI adjustable in steps of 10.
• Receiver. Both include the Link 8K Receiver, which takes polling up to 8000Hz. The receiver has two buttons and an LED, so you can change DPI and other settings without opening software.
• Software. Both use Bibimbap web software to set DPI, polling rate and button mapping.
• In the box. The mouse, the Link 8K Receiver and a USB-C cable.

Eight thousand hertz is not automatic. Pulsar's condition for 8K polling is a processor at Core i5 or Ryzen 5 level or above, with a USB 3.0 socket for the receiver. A desktop built in the last few years clears that without effort, so this is mostly a reminder to plug the receiver into a USB 3.0 port and not an old one at the back of the case.

🖱️ Switches and feet

Both mice use Pulsar optical switches, which trigger with light instead of a metal contact. Pulsar says this avoids the double-click fault that worn mechanical switches develop. That is the only switch claim the pages make for this pair, so there is no click-count figure to compare, and none should be assumed.

On feet, the box is plain. Neither CARPE-X nor BUZZ-X ships with the 16 dot skates that come with Susanto-X and JV-X. If you were hoping to swap to dot skates out of the box on this pair, that is not part of the package, and the feet already on the mouse are the ones you start with.

🧭 Settling it at a South African desk

Evetech sells both mice to South African buyers online, which means the choice is made from numbers and not from holding the shell. Here is a short routine that works with a ruler and a few minutes.

1. Run the ruler from the base of your palm up to your longest fingertip. A hand that is close to the 126mm shell length is the CARPE-X case.
2. Measure across the knuckles. The width gap between the pair is only 0.4mm, so width will not split them.
3. Lay your hand on the desk the way you play. Flat palm points to CARPE-X; arched knuckles point to BUZZ-X.
4. Check the port. Put the Link 8K Receiver in a USB 3.0 socket and remember the processor condition if you want 8000Hz.

The price of each mouse is shown on its product page at Evetech, so it is worth opening both once you have a grip preference.

If neither suits, the wider wireless mouse range at Evetech covers the other Pulsar shapes and sizes, from the 35g X2 CrazyLight Mini up to the 62g Chosen Gen.2. The Pulsar range lists both mice next to the other shapes and weights in the line.

Frequently Asked Questions

Is the 1g weight difference noticeable?

No. CARPE-X is listed at 60g and BUZZ-X at 61g, and Pulsar gives each a plus or minus 2g tolerance, so the gap sits inside the margin.

Which one is longer?

CARPE-X, at 126mm against 124.6mm for BUZZ-X. BUZZ-X is the wider one by 0.4mm.

Do they need different receivers or software?

No. Both ship with the Link 8K Receiver and both use Bibimbap web software for DPI, polling rate and button mapping.

Can the Link 8K Receiver change settings without software?

Yes. It has two buttons and an LED, and Pulsar says you can change DPI and other settings with it directly.

Do these two come with dot skates?

No. The 16 dot skates belong to Susanto-X and JV-X in the Pulsar Pro Series, not to CARPE-X or BUZZ-X.

What does 8000Hz need from my PC?

A processor at Core i5 or Ryzen 5 level or higher, plus a USB 3.0 socket, as Pulsar words it.
