Before buying PC upgrades, check compatibility first. This guide explains what to check for RAM, graphics cards, SSDs, power supplies, case size and motherboard support.
Quick answer
Before buying PC upgrades, check your motherboard, RAM type, available slots, power supply, case space, storage connectors and whether the upgrade is worth the cost.
Check the exact PC spec
Do not guess. Find the motherboard model, CPU, RAM type, PSU wattage, case size and current storage setup before buying parts.
Check RAM type
DDR3, DDR4 and DDR5 RAM are different and not interchangeable. Check available slots and maximum supported capacity.
Check GPU size and power
Graphics cards need enough physical space, enough PSU wattage and the correct power connectors.
Check storage support
SATA SSDs are widely supported. NVMe SSDs need a compatible M.2 slot.
Check value for money
Some upgrades are not worth doing on very old systems. If multiple parts need replacing, a new PC may be better.
