AMD Radeon Chips Comparison Table (desktop)
Power Supply
Contents
Below we list the minimum power supply for each video card, according to AMD. Chips that are not listed mean that AMD doesn’t publish mnimum power supply requirements for them.
It is important to have in mind that these are worst-case scenario values. Under normal operating conditions, a GPU will consume less power than listed in the table below. The power supply requirements are usually inflated, as the manufacturer has to take into account “bad” power supplies available in the market that are not capable of delivering their labeled power continuously.
