General Warranty Terms & Conditions

1. General Warranty Coverage

All products—including Brand New, Open Box, and Used items—are subject to the same warranty conditions, inspection standards, and exclusions outlined in this policy.

Open Box and Used items receive the same manufacturing-defect coverage as Brand New items. However, they may have a shorter designated warranty period, as specified on the product page or purchase invoice.

Power Protection Requirement

Due to extreme grid-voltage fluctuations ranging from 180V to 250V, all systems, individual components, and electronic devices must be powered exclusively through a verified, high-quality Uninterruptible Power Supply (UPS).

Failures or damage caused by the following are strictly excluded:

  • Power spikes or electrical surges
  • Brownouts or unstable voltage
  • Physical or accidental damage
  • Liquid exposure
  • Improper handling or misuse

These exclusions apply to products in all conditions, including Brand New, Open Box, and Used items.

Strict No-Tampering Policy

Opening or disassembling any device—including user-accessible hardware such as custom PCs, pre-built PCs, laptops, graphics cards, and power supplies—will immediately void the warranty.

Breaking or removing any store or factory warranty seal will also void all coverage.

The following work must be performed exclusively by our technical service center:

  • Internal dust cleaning
  • Thermal paste replacement
  • Hardware upgrades or replacements
  • Routine internal maintenance
  • Diagnostics and repairs

2. Pre-Built Gaming PCs, Custom Builds and Laptops

Pre-Built and Custom-Built Desktop PCs

Every individual hardware component installed inside the system is covered under its respective manufacturer’s warranty.

The system must remain connected to a verified, high-quality UPS at all times.

The overall system and component warranties will be voided if the customer:

  • Opens the case
