What power supply does your PC need?
Complete wattage table by GPU and CPU for 2026 / 2027
Find your graphics card in the table, cross-reference with your CPU and get the minimum recommended wattage for your build. No calculators, no formulas.
The wattage figures include a safety margin above the real system consumption (GPU + CPU + RAM + storage + fans + motherboard). They are not the sum of GPU and CPU TDP.

Note on the wattage figures in this table: the figures shown are not the sum of GPU and CPU TDP. They include a safety margin that accounts for the real total system consumption (cooling, storage, RAM, motherboard and fans) plus an additional 20-30% buffer to absorb momentary consumption spikes. Modern GPUs such as the RTX 5090 or RX 9070 XT can spike up to 200% of their TDP for fractions of a second - the PSU must be able to absorb those spikes without cutting power.
Bronze or Gold? Modular or non-modular? The decision in three questions
Which certification do I choose?
Gold converts between 87-92% of energy into useful current. Bronze, between 82-85%. The difference is around 8-12 euros per year in electricity. If budget matters more than marginal efficiency, Bronze with quality capacitors like the BZ PRO range is the right call. If you want the best electrical performance and have the budget, the GDX V3 Gold.
Modular or non-modular?
Full modular (GDX V3) means you only connect the cables you use: the inside of the case stays clean and airflow improves. Recommended if you have a case with a transparent side panel or if cable management matters to you. Non-modular (BZ PRO, BZ V2) works perfectly fine for any build - unused cables are hidden in the rear compartment of the case.
Do I need ATX 3.1?
ATX 3.1 requires the PSU to handle spikes up to 200% of its capacity for 100 microseconds. If you have a latest-generation GPU (RTX 50, RX 9000) that uses the 12V-2x6 connector, an ATX 3.1 PSU with a native cable is the safest option. The entire GDX V3 and BZ PRO ranges comply with ATX 3.1.
