Up0104s Datasheet [work]

Frequently found in GPU power stages (e.g., MSI GTX 650) as a stabilizer for auxiliary voltage rails.

with the UP0104P without checking your schematic; the pin assignments differ to optimize power delivery vs. signal integrity. Up0104s Datasheet

If you are repairing a device and see a small 3-pin or 8-pin chip marked with "UP0104," "uP0104," or "0104s," you have found your regulator. In many cases, failure of this chip results in the device failing to "power on" or exhibiting "no display" symptoms on a GPU, as the logic chips aren't receiving their required voltage.
