Buyer rule
Start with GPU load, PSU standard, cable path, and case fit
Choose 1000W around GPU class, CPU load, native cable support, case fit, fan curve, efficiency target, and future upgrade plans.
1000W PSU prices
Use a 1000W PSU for headroom without ignoring cable and case fit
A 1000W PSU is a strong single-GPU lane, but a large number on the label does not solve wrong cables, bad case clearance, or poor modular cable matching.

Risk
Avoid buying wattage without checking the connector path
The common mistake is buying extra wattage while still using a poor cable path or a cramped connector bend.
