yes ATX will work, but recomend u to use AT instead, read above why.

my tower (RBM TOWERHAWK IIc) came with ATX bla bla , but i had to get an AT psu and remove all the ATX stuff due to my mediator is the first version (pci1200) and has no ATX support.

in general no big changes but its the connectors that counts and since u have an Powertower well go for AT

cheers

No no no CU an ATX PSU will not work in your current setup without a lot of rewireing and a lot of hastle. Your machine needs an AT PSU, and it would be better if you could get one above the 200 watt mark. Unfortunatly AT PSU's new are now rare, the last one I got, I got from an online mailorder company because I couldnt find any in my local area. I hope im not too late...

I think you guys are all wrong.

It's obvious that the cause of this problem is the fact that he switched on the machine with the intention of listening to REM.

Amigas tend to brake down when switched on with the intention of listening to crap music, the only exception being A2000 Professional Systems equiped with Military Grade Chips (MGC), which are designed to withstand such abuse.

The only solution to your problem is playing a Hawkwind record, not forgetting to place the turntable close enough to the faulty unit, for the positively charged psychedelic energy waves to be able to reach it.

I hope this solves your problem and please don't send any money for my helpful instructions. I'm always glad to help. :-)

The SCSI chip only gets hot when it is worked. Lots of large file transfers burning CD's and such. CD burning was my major reason for putting the Heatsink on the chip I remember having to burn 250 CD's one night and I had the case open and a big fan blowing on the chip so as not to get frisbee's.

No don't glue a coin to the chip. The Magazines idea was to wedge a coin under the original heat sink so it connected to the scsi chip the idea was so it would tranfer heat to the original heat sink and be disapated. Brrrr!

Me I would just glue a stand alone heat sink on it using thermal epoxy. Or you could use the double sided heat sink tape. I once had a bad experience using double sided heat sink tape on the SCSI chip during one demonstration at a local users group in the middle of the demo there came a tinkling sound from inside the case like someone droped a pair of keys. The machine froze and reboots resulted in nothing. The thing fell off and shorted things out as it tumbled down the inside of the case.

I now use Artic Silver Epoxy on all my heatsinks.
Thermal tape works good too mine held on for years but my computers spends a great deal of time on the road and NY potholes are a killer.

So I like using the epoxy.

one of the hottest chips on the PPC board one that will remove skin is the one on the opposite side of the PPC down by the connector. If it gets hot put a heat sink on it.

one more to add to this marathon post don't use crazy glue. The heat will evaporate it and the heatsink will fall off.

Use only glue or tape made for heatsinks.

you know what would work good buy one of those chipset cooling sets they cost under a tenner they come with three heat sinks and a fan inludes the proper tape and stuff. The southbridge cooler is a perfect fit for the SCSI chip.

@CU_Amiga

probaly too late but buy an AT power supply if thats what you originally had in the tower.
AT has two six pin power connectors labled P8&P9
make sure you have all the black wires facing each when you reconnect it. Example!
 org red yel blu blk blk blk blk blk white red red red

ATX has one twenty pin power connector.

Worst case come back here and we can show you how to make an ATX adapter that will work with your setup.

Or you can buy one from Elbox or Me I make a few different ones.

I got an Voodoo 5500 in my A1200 havn't really tried any 3D games with it other than Wipeout 2097 and heretic II. It works great as far as I can see. Havn't tried it with Freespace or Quake II yet

@everyone

Okay, thanks for the help. Shame it was a little too late! :-) Luckily, i still have a bit of cash flowing about to get yet another PSU. Could someone please provide a link as to where i can get an AT PSU (300W), homebrew or company. Or how could i make this ATX PSU work at all (it won't even switch on!). Thanks again for all the help guys, i think i can get through this! :-)

Cheers,

-edit-

@kgrach

Or how to make an ATX adaptor  :-D

OI! What's wrong with REM?!  :-D  If REM are that "bad" then God only knows what would have happened if i switched on Tina Turner, and her cat walling! :-)

@CU_AMiGA

Hows about you do a bit of work yourself? ;-) goto google and search for retailers in the UK that still stock AT PSU's. Also browse ebay... they tend to pop up there too... though I wouldnt hold your breath re a 300watt one, I've never seen them go above 250watt. Remember AT is old technology, they were used when the x86 cpu's werent massivly power hungry like they are now on ATX form factor motherboards.

[Ryu]

also I belive both eyetech and elbox sell ATX to AT converters so you might want to check that out if you want to get your current ATX PSU to work with your setup.

[CU_AMiGA]

@Ryu,

I have already searched for AT PSU on google, but i just kepted getting ATX ones  :-x I have also looked on Elbox and Power Computing websites, but they just stock the standard 240W ones, i may get that as a last resource, but really want a 300W one. To be honest, i only thought there were one type of PSU, not AT and ATX.

Cheers

[CU_AMiGA]

@Ryu

Oh, i completely forgot about eyetech.

[CU_AMiGA]

Found the ATX - AT adaptor! :-) I will have a closer look tomorrow. Cheers,

[Ryu]

the main difference between an AT and ATX PSU is that the ATX PSU is always live, and is turned on and off via "software", wheres an AT PSU is turn on and off with a proper switch. Thats why on modern PC's you can switch them off from the shut down option, because the PSU is connected to the motherboard, so it can send the off signal to the PSU.
