GPU upgrade: power supply, cables and space
Build a concrete checklist for the exact variant you intend to buy.
Updated on · Compatibility and upgrades
What to consider first
Before replacing the GPU, identify the variant and compare power requirements, cables and dimensions with the actual power supply and case. Missing data becomes outstanding checks in the plan; it must not be interpreted as compatibility.
The diagnostic does not measure FPS, bottlenecks or power supply condition. Documented compatibility and application performance are different assessments.
1. Choose the variant, not just the chip
A card advertised by its GPU name can still have a different manufacturer, memory, cooler and dimensions. Match the exact model to the catalog; if it is unavailable, record the name as an unverified part without copying another model's attributes.
2. Compare power requirements and dimensions
Open the card's specification page and check its power requirements, connectors and dimensions. Compare them with the power supply manual and the case's documented clearance, accounting for other installed components. The Sapphire PULSE RX 6600 specification page is an example of a model reference; its data must not be transferred to an RX 580.
3. Turn uncertainties into prerequisites
An unidentified power supply, an unknown cable or a case without measurements must remain outstanding checks. Put those confirmations before the purchase in your plan. LivoPC's diagnostic explains which data each rule used and does not calculate FPS gains or a universal bottleneck percentage.
