How do I know whether a graphics card fits the PC case?

Case GPU clearance must be compared with the card length, height and thickness after front fans or radiators are installed. Before ordering, confirm the smallest remaining clearance in the planned layout.

What motherboard sizes can a mid-tower case accept?

Support varies, although many mid-towers fit ATX, micro-ATX and Mini-ITX boards with specific standoff positions. The decisive product-card check is the chassis compatibility list for the chosen board.

Does an 80 PLUS rating prove that a PSU is high quality?

80 PLUS measures efficiency at defined loads and does not by itself certify voltage regulation, component quality or protections. Use professional electrical testing of the exact PSU model to make the comparison.

How much power-supply wattage does a gaming PC need?

Required capacity depends on CPU and GPU draw, transient peaks, connector needs and sensible operating margin. Match the purchase to component-manufacturer guidance and measured system consumption.

Will a 360mm radiator fit in any large PC case?

Radiator support can conflict with tall memory, motherboard heatsinks, drive cages or a long graphics card depending on mounting position. Look for radiator thickness plus fan depth in the final build in the full specification.

What is the difference between modular and fixed PSU cables?

Fully modular units detach every cable, semi-modular designs retain core leads and fixed supplies keep the complete loom attached. Base the decision on ease of routing against budget and case space.

Why does PSU cable compatibility matter when upgrading?

Modular cables are not universally wired, even when plugs appear identical, and mixing sets can damage hardware. The listing should state using only cables approved for that exact power-supply series.

How many case fans are useful?

A balanced intake and exhaust path matters more than filling every mount, with component heat and case restriction setting the need. Assess temperatures and noise after the basic airflow is established before choosing a model.
