I'm putting together a PC with a Ryzen 7 5700, RTX 2080 Ti, 16GB of DDR4 memory, a Gigabyte B550 UD AC motherboard, a Zalman S4 case, and a 1TB KingBank NVMe SSD. I estimate that a 550–600W power supply should be enough, but I'm unsure which brands and specific models are reliable. What would you recommend, and should I leave extra wattage for future upgrades?

Corsair’s RM series is a dependable choice and tends to run very quietly. A fully modular model is also convenient because you only need to connect the cables you actually use, which keeps the case cleaner.
Seasonic is usually a solid recommendation, and Montech can be a good budget option depending on the exact model. Corsair and Thermaltake also have worthwhile units, but their product lines vary, so check the specific model rather than relying only on the brand name. Look for a reputable 80 Plus Gold unit rated around 600–650W, with 650W being the more comfortable choice for the 2080 Ti.
I’d compare available models against a reputable PSU quality-tier list and generally aim for a B-tier or better unit. For a system with an RTX 2080 Ti, a good 650W Gold-rated supply from a trusted manufacturer would be a safer target than choosing strictly by the lowest wattage. The ASRock PRO-650G is one budget-friendly example if it’s available at a good price.
Sorting a quality list by price can make this easier. I’d still verify the exact model, since a brand can have both excellent and mediocre power supplies.
There’s probably no need to jump all the way to 850W unless you’re planning a particularly power-hungry future graphics card. Around 650W should provide reasonable headroom for this build.
I agree—detachable cables are worth having. You can leave the unused ones out of the case instead of managing a bundle of extras.
