The ATK V75X and ATK V75K are two versions of the same 75% keyboard from ATK. They share an identical CNC aluminum top case, the same five switch options, the same tri-mode connectivity, and the same double-shot PBT keycaps. The differences are three: battery capacity, PCB design, and internal sound dampening. This guide explains exactly what those differences mean in daily use so you can pick the right version without overpaying for features you do not need.

PCB: Non-Slotted vs Single-Key Slotted
The PCB difference is relevant if you plan to swap switches. The V75X has a non-slotted PCB. Every switch sits in a standard hot-swap socket and can be removed with a switch puller included in the box. This works well for changing all switches at once or for replacing a failed switch.
The V75K has a single-key slotted PCB. Each switch socket has a small cutout that allows you to lever out individual switches more easily using the puller tool. This makes individual switch swaps faster and reduces the risk of accidentally pulling out adjacent switches. If you plan to mix switch types across the keyboard - for example using tactile switches on the home row and linear switches elsewhere - the slotted PCB makes the process more manageable. For users who will choose one switch and keep it, the PCB difference has no practical effect on daily use.
Sound Dampening: V75X vs V75K
The V75X includes four sound dampening layers: Poron foam, IXPE pads, switch base foam, and silicone base pads. These sit between the switches, the PCB, and the case, absorbing resonance at multiple points in the sound path. The result is a controlled typing sound without the hollow resonance common in budget keyboards.
The V75K adds an extra set of PET pads on top of these four layers. PET is a stiffer material than Poron or silicone. Its role in the sound stack is to tighten the acoustic decay of each keystroke. The typing sound on the V75K is marginally more contained and shorter than the V75X. In a blind listening test, the difference is subtle. In side-by-side comparison in a quiet room, the V75K sounds slightly more precise. For most users, both keyboards sound well-dampened relative to the competition at this price point.
Switch Options: Identical Across Both Models
Both V75X and V75K are available with the same five ATK custom switches. The switch choice affects typing feel, gaming performance, and sound more than the PCB or dampening layer difference between the two models. If you are undecided between the two keyboards, resolving the switch choice first is the more important decision.
| Switch | Type | Actuation Force | Actuation Point | Total Travel | Notes |
|---|---|---|---|---|---|
| Anya | Linear | 42gf | 2.0mm | 3.2mm | Sound-focused linear. Shorter travel. |
| Arctic Fox | Tactile | 56gf | 1.7mm | 3.6mm | Quick-trigger support. Gaming recommended. |
| Aurora Ice Cream | Linear | 40gf | 1.4mm | 3.5mm | Lightest actuation point. BOX structure. |
| Periwinkle | Linear | 40gf | 2.0mm | 3.7mm | Nylon shell, POM stem. Fast rebound. |
| Obsidian | Linear | 45gf | 1.9mm | 3.5mm | Balanced weight and travel. |
Which One Should You Buy
The decision between V75X and V75K comes down to two questions: how often do you charge, and do you plan to swap individual switches?
Buy the ATK V75X if:
- You plan to keep one switch type across the full keyboard and do not need per-key swapping
- You want the lower starting price: ₹6,799 versus the V75K premium
- Weight is a consideration for your desk setup or mobility
Buy the ATK V75K if:
- You plan to experiment with different switches per key position and want easier individual removal
- You want the marginally tighter sound profile from the additional PET pads
- Battery longevity is a priority for multi-day travel or irregular access to charging
For the majority of Indian buyers using the keyboard at a fixed desk with regular charging access, the V75X offers the complete ATK feature set at a lower price. The V75K is the right choice specifically when extended battery life or per-key switch flexibility is the deciding factor.
Frequently Asked Questions
Can I upgrade a V75X to V75K internals?
No. The PCB, battery, and internal foam layers are not sold separately as upgrade kits. The V75X and V75K are different configurations of the same chassis. If per-key slotted PCB and extended battery are important, purchase the V75K directly.
Do both models support the same software?
Yes. Both use V HUB for key remapping, ARGB control, and quick-trigger configuration (available only with Arctic Fox switches). The software experience is identical across V75X and V75K.
Is the sound difference between V75X and V75K noticeable?
In a quiet room with the same switch, yes, there is a subtle difference. The V75K has marginally tighter, shorter acoustic decay due to the extra PET pads. For most users, both keyboards sound well-controlled compared to the competition in this price range. The switch choice produces a larger sound difference than the PCB variant.
Which variant is currently available in India?
Both V75X and V75K are available through Vrkaa on a pre-order basis. Check the ATK V75X product page on vrkaa.com for current availability, variant listing, and dispatch timeline.
What does single-key slotted PCB mean for switch swapping?
A slotted PCB has a small cutout next to each switch socket. When you use a switch puller, this slot gives the tool a leverage point to remove individual switches without disturbing neighbouring switches. On a non-slotted PCB (V75X), the switch puller grips the switch from above with no slot assistance. Both methods work reliably, but the slotted design (V75K) is more convenient for frequent individual switch changes.
