600watt is given on the website, but it only uses like 250 watt max. So 550 would be enough.

To clarify; TDP is a heatsink rating, not total power draw. It can pull more than 250watts from the wall, and especially true when overclocked.

Case: Corsair 4000D Airflow; Motherboard: MSI ZZ490 Gaming Edge; CPU: i7 10700K @ 5.1GHz; Cooler: Noctua NHD15S Chromax; RAM: Corsair LPX DDR4 32GB 3200MHz; Graphics Card: Asus RTX 3080 TUF; Power: EVGA SuperNova 750G2; Storage: 2 x Seagate Barracuda 1TB; Crucial M500 240GB & MX100 512GB; Keyboard: Logitech G710+; Mouse: Logitech G502; Headphones / Amp: HiFiMan Sundara / Mayflower Objective 2; Monitor: Asus VG27AQ

OC3D did a pretty good review on it.  In their overclocked test system, the whole system used about 457 watts.  With all the parts in his system PCpartpicker estimates the system minus the video card could be using up to 300 watts alone, meaning 157 watts might only be used by the video card, but still, TDP and energy consumption have always been really close.  So I would say it probably does consume around 250 watts, and a 550 PSU is probably good enough.  Also, his system was using an overclocked 4960x, which uses a good bit more power than the more common enthusiast chips.
