Heh. I havent noticed that at all.. And unless that starboard is an EXTREMELY inefficient design, I find it hard to believe, unless (as I stated earlier) its actually spinning a hardisk inside the unit off the same power..
My A500+ has a 68030@50mhz, 68882@50mhz, 32 megs of ram, PLUS a GVP sidecar with 8 more megs of ram and a 3.5" desktop hardisk, all running off the stock A500 psu.. and no problems whatsoever..
My other A500+ has the same GVP sidecar, also with 8-megs of ram and a desktop hardisk, and it uses a single stock A500 PSU..
My Rev 6a A500 has a supra 500XP sidecar with 8 megs of ram and a desktop hardisk inside it, and (yep, you guessed it) runs off the stock A500 PSU..
Ive never had any problems running any of these machines this way.. In fact, Ive noticed that some PC power supplies cause a noticeably degregation of the audio clairity/quality on A500s..
Anywayse.. If theres no jumpers to enable "shared power" in that thing, then I'd reccomend going with a second PSU for it... That old DIP package DRAM is pretty power-hungry by comparisson to later chips used on SIMMs.. So its quite possible that it does need some serious "juice" to run it...
But the A500 PSU does have quite a bit of "extra capacity".... It has no problem running the A500, an accelerator, and most modern low-powered add-on devices..
