Hmmm... I don't know if I can add too much here, the PSU is the first thing to look at but that's already sorted. Still, you might have a look at the 5V rail after the machine's been on long enough for the problem to occur, with the accelerator and without, just in case it's dropping with the extra load. Usually the A1200 resets before the rail drops too low for the chips, but there could always be something else going on too.
I can't say for sure why an error might happen in chip RAM only when the accelerator is attached. The chip RAM bus is isolated from the accelerator by Budgie and Alice, so it's more likely down to some issue with timing, crossing the clock threshold between the CPU and the AGA chipset. With the timing fix capacitors already removed, I don't really know what else can be done there however, other than the usual - cleaning contacts on the motherboard connector, slowing down the ACA clock speed to see if it goes away, etc.
