❓ Common Questions

Real questions customers ask about this product — delivery, warranty, payments & compatibility.

Is this product available in Lebanon?▾

Yes — it is available at Technodel with delivery across all of Lebanon: same-day to Beirut, Sour, Tripoli and surroundings, and 1–2 days to every other region.

Where does Technodel source this product?▾

Technodel sources from established suppliers in Lebanon. The product page states its condition and its warranty, and compatible parts are labelled as compatible.

What warranty comes with this product?▾

Warranty terms are stated on each product page. Where a manufacturer warranty applies, warranty support is handled through Technodel.

How can I pay for this product?▾

Technodel accepts cash on delivery, Wish Money transfer, and cryptocurrency (USDT, BTC, ETH). Delivery is a flat $4 anywhere in Lebanon, free on orders of $500 or more.

Is this power supply enough for my PC build?▾

Add your CPU + GPU power draw plus ~30% headroom. A quality 650–750W 80+ Gold unit covers most single-GPU builds; high-end GPUs (RTX 4080/4090) typically want 850W+. Modular units ease cable management.

What's the difference between modular and non-modular PSUs?▾

Fully modular PSUs attach only the cables you need — tidier builds. Semi-modular fixes essential cables but frees the rest. Non-modular is cheaper but all cables are fixed.
