It can run in turbo and is rated for that, but there is little headroom, OCP will kick in at about 210-220 watts.
Next gen PSU will be able to run at ~300 watts.
Great to hear, thanks a lot! In case I want to get something more powerful right away though, regular ATX PSU's come to mind at first. Anything wrong with a single rail Seasonic PSU? I should be able to just connect a PCIe cable to it and use it for the Apollo right?
Any off the shelf ATX PSU (sized appropriately) should work fine. You just need to be aware that for the PSU to power itself up when the power switch is moved to the ON position requires you to jump two pins on the 24-PIN motherboard cable. This of course means that in addition to the PCIe power cables, if it's a modular PSU you also need to connect the 24-pin cable to the PSU.
