Frequently Asked Questions
Are 2000W power supplies overkill for gaming?
Yes most single GPU systems only need 1000W. You only need 2000W for extreme multi GPU setups or mining rigs.
Can I use server power supplies in ATX cases?
Usually no because server units use different form factors and connectors. You may need adapters or specific chassis modifications.
What does Platinum efficiency mean?
Platinum means the unit converts at least 92 percent of power at full load. This reduces energy waste and electricity costs.
Do I need a 12V-2×6 cable?
Yes if you are using RTX 40 series GPUs. It is safer than using a PCIe 6pin adapter for high wattage cards.
How often should I clean a power supply?
Clean it every three to six months depending on your environment. More dust means more frequent cleaning is required.
Is a renewed power supply safe?
Only buy renewed units from reputable sellers with testing. Avoid unknown sources to ensure electrical safety.
