Dell XPS One 2720 AIO Liteon PS-3261-9DA not starting up immediately

[cheeky2]

I suspect the issue is with the power supply Liteon PS-3261-9DA as apparently they are notorious for issues with them. Has anyone else had similar issues where the PC tries to boot up a few times before finally booting up. Now I have opened up the PSU which shows no signs of any capacitors failing. I did remove one capacitor that looked to have an issue however with my peak meter it showed it was within the limits with good very low esr values which was somewhat disappointing!
I am going to put a Meter leads across the outputs to see how stable they are when it occurs to see what they are like.
Anyone had any thoughts with where the problems lie with this PSU as I am sure I am not the first to try to repair the issue with one of these PSU units.
Thanks in advance for ant help.

Good news I have managed to track down a high ESR Samxon 10uF 50V capacitor that was causing the issues
Picture attached for location of the high ESR capacitor around 2.2ohms, replaced with a Panasonc FR capacitor. I guess it was cooked with the heat inside this small unit especially as there was dust build up by the fan furthering the build up of heat inside the unit. I did also notice another 2.2uF 50V capacitor that did also have a slightly high ESR (circled in red), however I didn't have a suitable Panasonic capacitor to replace it with. The yellow circled capacitors were the ones checked before I identified the culprit with my trusty Peak ESR70 meter.
