Yes, it’s worth it. The core advantage of a used graphics card is cost-effectiveness (prices are typically 30%-60% lower than new ones), making it ideal for budget-conscious users needing high performance (e.g., gamers, designers).
Drawbacks: It carries risks (e.g., mine-used GPUs, hidden defects, reduced lifespan) and lacks official new-card warranties (some platforms offer third-party extended warranties).

• Users with limited budgets but needing a "cost-performance" balance (e.g., RTX 3060/4060 mid-range cards);
• Those with short-term needs (e.g., students transitioning before graduation, temporary project use);
• Users with basic hardware knowledge who can self-test or accept "inspection costs";
• Environmentally conscious individuals (reducing e-waste, supporting circular economy).

A "mine-used GPU" refers to a graphics card previously used for cryptocurrency mining. Mining requires 24/7 high-load operation (high power consumption, elevated temperatures), which accelerates aging (degradation of VRAM/core, shortened capacitor lifespan) and may cause issues like screen artifacts or crashes.
Used GPUs are prone to mine-used risks because some sellers may conceal their mining history.

Use a three-step verification: "software + hardware + visual inspection":
• Software checks: Use GPU-Z to view "Power-On Hours" (~500–2,000 hours is normal; 5,000+ = likely mine-used). Run FurMark to check for artifacts/throttling.
• Hardware checks: Disassemble the GPU to check capacitors, dust, and gold finger oxidation.
• Visual: Look for suspicious stickers or "mine farm" labels. Ask seller about usage (12+ hours/day = red flag).

• Core/VRAM damage (artifacts, black screens, crashes);
• Capacitor aging (unstable power, reboots);
• Cooling issues (noisy fans, clogged heatsinks);
• Port damage (faulty HDMI/DP).

• Gamers: RTX 3060, RTX 4060, RX 6650 XT;
• 2K ray tracing: RTX 4070, RX 7800 XT;
• Design/productivity: RTX 4070 Ti, RTX 3090;
• Avoid: Older high-end (GTX 1080 Ti, RTX 2080 Ti) due to high power use and outdated performance.

Typically 20%-40%.
Example:
• RTX 3060 (non-mine-used): ~RMB 1,200-1,500;
• RTX 3060 (mine-used): ~RMB 800-1,100 (not recommended).

Yes. Usually paid (~RMB 50–100). Process:
1. Select "inspection" and pay;
2. Platform lab performs 72h load test (FurMark, 3DMark), hardware check, game test;
3. Issues a report; if failed, platform handles refund.

Usually 1–3 months store warranty, covering:
• Core/VRAM damage;
• Power module issues;
• Fan failure (not human-caused).
Exclusions: Water damage, BIOS flashing, drops, aging.

Submit return within 48h with evidence. Platform will:
1. Arrange return shipping;
2. Confirm issue and refund.
Note: Requests after 48h or human damage may be rejected.

Yes. Best times:
• 1-2 months after new GPU releases;
• Big sales events (618, 11.11);
• Crypto crashes (mine-used influx, beware).

Mine-used GPUs may consume 5%-10% more (aging capacitors).
Check product details; e.g., RTX 4060 ~160W, needs ~500W PSU.

No. Only original buyers from official channels get OEM warranties.
Used cards rely on store/platform warranty instead.
