Stability of 3.3V rails on PCIe slots, anyone know?

We're testing an SSD that fits in a 1.8" PCIe adaptor card, I'm not sure who makes the motherboard (it's been rebranded, I'm trying to find out) but does anyone know what kind of tolerances these slots usually have in terms of power lines?

Our SSD won't run at less than 3.27V, which is pretty rubbish, but depends completely on the regulation of the motherboard. The PSU output is 3.3V ±5%, so we need to know what regulation is on the motherboard and/or the PCIe card to keep it up at 3.3V or more.
