I'm planning to add a second RTX 5070 Ti for running local LLMs, so I need to upgrade my power supply. The SAMA P1200 is a 1200W Platinum-rated ATX 3.1 unit with two 12V-2x6 connectors, which would let me power both graphics cards without using an extra adapter. SAMA seems like a budget-oriented brand, so I'm unsure whether this particular model is dependable or if I should spend more on a better-known manufacturer. Has anyone used SAMA power supplies or researched the P1200?

SAMA has both good and mediocre models, just like most manufacturers. The P1200 is considered one of their better units, and its Platinum efficiency and ATX 3.1 support make it a reasonable option for a high-power build. A PSU quality tier list is a good way to verify the exact model rather than judging the entire brand.
A Platinum efficiency rating is useful, but it isn’t by itself proof that a PSU is well designed. Check independent testing or a current PSU tier list for the exact P1200 model, and make sure the total system power and connector requirements are covered. Based on the available rankings, this particular unit looks like a legitimate option rather than a generic budget PSU.
The specific model matters more than the brand. The SAMA P1200 is generally rated in the top tier of reputable PSU lists, so it appears to be a solid choice for this setup. Its native dual 12V-2x6 connections are also useful for two modern GPUs.
SAMA’s better units seem to use respectable components and have performed well in technical teardowns. I’d be comfortable using a good SAMA model, including the P1200, but I would compare its warranty and protection for damage to other components against similarly priced alternatives. Paying a little more for a manufacturer with a long, well-established warranty can be worthwhile when the system contains expensive hardware.
