Choosing a gaming keyboard among pc monitors & peripherals often comes down to a practical trade-off: do you want the Keychron C2PX's 100% format and 8,000Hz polling specification, or the 75% keyboard's volume knob and lower listed price? Both are new wired mechanical keyboards, but they aim at different preferences rather than offering the same feature set.
Quick verdict
Pick the Keychron C2PX when the 8,000Hz polling figure, RGB lighting, and included keycap and switch pullers are the deciding details. Its listed price is $16.74 higher, and it also includes a one-year limited parts and labor warranty.
Choose the 75% Wired USB Mechanical Gaming Keyboard when a volume knob, LED backlights, and the $30 listed price matter more. Its gray-and-yellow presentation and standard English QWERTY layout make its stated configuration especially straightforward for shoppers who want those particulars.

Where each keyboard wins
Keychron C2PX wins on the named performance specification and included extras. The description calls out an ultra-fast 8,000Hz polling rate, while the box contents include a USB Type-C cable, a USB Type-A-to-Type-C adapter, and pullers for keycaps and switches. That combination gives the C2PX a clear case for shoppers focused on those specific connectivity and maintenance accessories.
The 75% Wired USB Mechanical Gaming Keyboard wins on price and direct controls. At a $16.74 lower listed price, it pairs LED backlights with a dedicated volume knob. That is the more fitting route when adjusting volume from the keyboard itself is a priority and the named 75% configuration is the preferred format.
Product notes
Keychron C2PX 100% Custom Wired RGB Mechanical Gaming Keyboard

The Keychron C2PX is the better match for a shopper who wants a wired RGB mechanical keyboard with an explicitly listed 8,000Hz polling rate. The included USB Type-C cable and Type-A adapter add flexibility to the connection accessories, while the keycap and switch pullers are useful inclusions for someone interested in changing or handling those keyboard parts. A one-year limited warranty is listed for both labor and parts. The limitation is format-specific: the C2PX is presented as a 100% keyboard, so it is not the natural pick for someone deliberately seeking the 75% configuration named by the alternative. Its USD 46.74 listed price also places it at the higher end of this two-keyboard comparison.
75% Wired USB Mechanical Gaming Keyboard with LED Backlights and Volume Knob

A dedicated volume knob is the standout reason to choose the 75% Wired USB Mechanical Gaming Keyboard. Alongside that control, the keyboard is described with customizable LED backlights, a standard QWERTY layout, and English language settings. The gray-and-yellow color combination gives shoppers a specific visual direction without requiring an all-black setup. The main compromise is straightforward: this keyboard is identified as a 75% model, not the 100% format attached to the Keychron C2PX. Shoppers drawn to the C2PX's stated 8,000Hz polling specification or its included Type-C adapter and pullers will find those details more aligned with the Keychron offering.
Final choice by use case
Choose the Keychron C2PX for a 100% wired RGB mechanical keyboard when the 8,000Hz polling specification, one-year limited warranty, and included keyboard accessories are worth the $16.74 price spread.
Choose the 75% Wired USB Mechanical Gaming Keyboard for a mechanical keyboard with LED backlights and a volume knob at the lower listed price. It is the clearer fit when those named controls and its gray-and-yellow QWERTY configuration lead your decision.
