This limited edition of the GamersNexus “GN15” Series Modmat is an exceptionally durable PC building anti-static conductive work surface, designed to protect your table and your components while also offering convenient reference materials and diagrams. The “GN15” Modmat is a 15-year anniversary design, celebrating 15 years of GN’s benchmarking and gaming content. It features the GN15 logo, new diagrams for motherboard front panel connector wiring, fan directionality, 8P8C/RJ45 wiring diagrams, CPU compositional cross-section diagrams, and more. This is a 4’ x 2’ (1220x610mm) surface, made of a rugged material to withstand years of PC builds, heat gun use for tube bending, and screw-tracking from video card tear-downs and re-pastes.
The Modmat includes a common ground point and anti-static wrist strap, and the “GN15” Series Modmat has 4x 10mm snaps for convenient connection, one in each corner of the mat. The Modmat is not intended for use as a mousing surface or as an active test bench and is most at home as a build surface. The nature of an anti-static conductive mat means that it should be used with components in an off state while building or assembling (isolate components under test from the mat, as it is anti-static conductive). This is one of the best ways to support us while getting a long-term work surface for your home workbench!

Update 6/26/2025: We have restocked a small quantity of these mats in our first print run of this design in years due to popular demand. You can find our newest GN15 design here.
The GamersNexus Modmat was designed by our team for use in tear-downs, PC builds, and enthusiast projects. The modmat is a 4' x 2' surface, using anti-static, rubberized material that stays in place and protects your components from electro-static discharge with its included common ground point and anti-static wrist strap. The rubber underside prevents the mat from moving on the table, and the mat's rubberized surface helps protect your table (and your components) from damage during system builds.These mats are large (at 4' x 2') and their weight speaks to the high material quality, at roughly 4 lbs. The Modmat is not intended for use as a mousing surface or as an active test bench (isolate components under test from the mat, as it is anti-static conductive) and is most at home as a build surface. The nature of an anti-static conductive mat means that it should be used with components in an off state while building or assembling.
The GamersNexus ‘Amp’ Medium Modmat offers a ground-up design from our team, featuring our customized and uniquely developed anti-static conductive surface to minimize risk of electrostatic discharge into components. The Medium Modmat is a portable, versatile alternative to our Large Modmat series; the Medium mats can easily be rolled and packed into a bag, brought for on-site service or repair, or just rolled-out as a permanent work surface in a smaller space. The ‘Amp’ Medium Modmat is 32” x 16” (~81x41cm) and uses our rubberized anti-static material to protect both the table surface from PC building and to protect the components.
NOTE: Due to an error with the print (does not affect the physical functionality of the mat), the remainder of this production run contains a misprint between the EPS12V and PCIe pinout diagrams; however, to remedy this, we are including a special, one-off PCIe die-cast metal pin with nickel plating and multiple layers of depth, plus two suede pinout diagram cards (with corrected EPS12V pins) that are spot UV treated for additional reflectivity. These cards use a thick cardstock and feature additional pinouts not included on the original Amp Medium Modmat, and in addition to the hole punch for pegboards, are made to be put up as reference material near your work bench. Prior customers of the Amp Modmat were contacted and offered these items and all future customers will receive these as part of the Amp Modmat. This only applies to the Amp.
The ‘Amp’ Medium Mat has a pinout wiring diagrams for quick reference, a motherboard outline (to scale!) with educational labels for new PC builders and a screw-tracking grid for disassembly of heatsinks, shrouds, and chipsets. The video card grid offers front-side and back-side screw tracking for GPUs, making it easier to re-paste and re-assemble cards. The Modmat is not intended for use as a mousing surface or as an active test bench and is most at home as a build surface. The nature of an anti-static conductive mat means that it should be used with components in an off state while building or assembling (isolate components under test from the mat, as it is anti-static conductive).
The Modmat uses anti-static, rubberized material that stays in place and protects your components from electrostatic discharge with its included common ground point and anti-static wrist strap. The Medium Modmat now has two snap locations for the Common Ground Point, better for ambidextrous use. Our wrist straps and common ground points have resistors in-line to even further minimize risk of damaging sensitive components, like MOSFETs, when working on PC parts.

4' X 2' ANTI-STATIC MODMAT & 32” x 16” MEDIUM MODMAT
The GamersNexus Modmats were designed by our team for use in tear-downs, PC builds, and enthusiast projects. The three Modmats currently available include the 'Original’ Large Modmat, the ‘Original’ Medium Modmat, and the new ‘Volt’ Large Modmat. The mats use an anti-static conductive, rubberized material that stays in place and protects your components from electro-static discharge with their included common ground point and anti-static wrist strap. The rubber underside prevents the mat from moving on the table, and the mat's rubberized surface helps protect your table (and your components) from damage during system builds. The modmat is not intended for use as a mousing surface and is not an active test bench (isolate components under test from the mat, as it is anti-static conductive). If you’re seeking a mouse mat or mousing surface, we have those available here.

COMMON GROUND + ESD Strap
The GamersNexus Modmat includes a free male common ground point (10mm stud, 6' cable) with two banana plugs, compatible with our included anti-static wrist strap. Static electricity will be grounded through the wrist strap, dispersed through the inner layer of the mat, and grounded to the wall through the common ground point. The ground point has a metal loop on the end that loops around the ground screw for a power faceplate, and the mat-side uses a female 10mm receptacle.
Power Connector Pin-out
Our Modmat includes a pin-out diagram for the terminating device-end of power supply cables, supplying quick reference material for 12V rails (for easy current clamping or monitoring), 5V rails, and jump start pins on the 24-pin connector. We also included wiring diagrams for 6-pin and 8-pin PCIe and EPS12V cables, with peripheral wiring diagrams including 4-pin MOLEX and SATA data and power cables. If you ever need to take a multimeter to your cables to check for continuity or voltage, the GN Modmat will make it easy.
Screw Organizer Tray
The left side of our mat offers a video card silhouette for easy screw tracking during mod projects, like hybrid mods or GPU tear-downs. This makes it easier to mentally track where the screws go when re-assembling the part, and is even sized roughly accurately to real video card sizes. We positioned the screw organizer on the left of the mat for distance from the grounding point, helping ensure the cable never interferes with screw tracking and organization.
The mat includes a ground point (10mm female snap) that connects with our included common ground point, ensuring all static-electricity has a direct path to ground from you and the mat.
Our Modmat uses high-quality materials that ensure a strong grip on the components, the surface, and a sturdy material to protect your underlying tables. The Modmat is built to endure multiple system builds and PC DIY projects, and is a product we built first for ourselves: We will be using this in daily disassembly and reassembly of parts and computers, and we hope you're as excited about it as we are.
