power issues A1200

[amiga4001]

I installed a slimline cdrom internal in a A1200.
Also fitted is a ide 4way splitter(buffered) and a 2.5 inch harddisk and a internal scandoubler.
Turbocard fitted is a blizzard mk3 with 32MB simm.
I hacked a AT psu for powering my system(200Watt).
System freezes on "heavy" use off cdrom.
When I power the cdrom with an extra psu ,so external all is well.
I power the cdrom with a soldered wire directly near the powerplugconnector.
Voltage I read when cdrom is going out is around 4.65V.
When I remove turbocard there is enough power it seems to keep on going.
Can it be wires off the old A500 lead which I used for the psu hack are getting old...too much resistance???
Any tips please..

The power for the cdrom is taken off the psu connector off the A1200.
So that shouln't put a load on the internal traces off the 1200.
Maybe I can fit another plug in the 1200 to power the cdrom.
Not nice but if it is necassery..

I tried that already.
Next thing I tried was taking it directly from the a1200 psu connector.
No working.
Guess I'll have to add another wire and connector from psu to A1200 to get it going.
