I can't imagine that 50 Watt PSU will be enough...
I thought a PSU of an SH205 could do it but that only delivers a modest 32 Watt
Kriegor wrote:The label on the underside of my Mega ST2 also says "120W", the PSU is labeled "50W", the manual says "Max 95W"... I'm not really sure what all that really means though. Apart from the fact that my PSU has gone bad (dry solders or bad caps/other components), it used to drive the Mega ST2 just fine and it's the original PSU.
JonB wrote:Well, I tried the 520 power supply, transplanting the circuit board into the Mega's power supply chassis (they do fit, the PCB and holes are exactly the same dimensions / positions). It didn't work, just made a high pitched whine and the Mega didn't power up. There are some differences between the boards, the Mega seems to have heavier duty components on it, and I think in this case it would be wise not to risk it. I really don't like the buzzing noise!
