RFM new power supply problem

[Dazzat]

Hi everyone hope someone can help me out here, I just bought a new psu 500w & followed this tutorial EXACTLY
http://antelopearcade.com/forum/yaf_postst4_Pinball-2000-AT-to-ATX-Power-Supply-Replacement.aspx

I did this due to it being the original psu and I looked inside it and things are not looking too well, the only thing changed is the fan.

It starts up, goes through the boot process, gets to the main screen during testing and the DONG noise goes... Then after that the RFM reboots and does the same process over and over again.
I have put back the in old psu and it works again as normal.

I am not doing anything different from the tutorial so I can't give you any other details, other than it is nearly exactly the same psu other than no power switch on the back of the psu

Hmmmmmmmm maybe it is this... as I'm on 1.5 but driver board is not unplugged
Version: 1.60 - SEP 22 2003
(Changes From 1.50)
Incorporate the final version of XINA (1.19) which fixes the problem
where booting the system with the power driver board disconnected
can cause factory reset to occur due to the mismatch of the last
country dipswitch setting in CMOS vs. the country setting for
an open power driver board cable.


Now it can go a bit further, it doesn't reboot at start, I can press start button and games starts and drops a ball but as soon as I press launch ball it reboots

I followed the same tutorial when I did my RFM without any dramas.

Couple of things to check;

What voltage is the offending power supply set to?

How have you wired up the on switch for the new supply? Maybe try wiring it to be always on.

Hi casperthefriendly
Yep tried it as always on as well, as majority all new PSU's use step conversion I don't have to worry about voltage problems or a switch on the back to change voltage.
Maybe that might be the problem being automatic

Maybe try another (older) power supply to see if you can get that one working?

For whatever reason it seems that the power supply is restting...

is the original P/S set to 110V?
I cant remember if the P/S runs through the internal transformer or not.
if the O/S is set to 110V and you say you can't switch your new one then try connecting the new one directly to a wall outlet with a standard PC 240v lead

also try bypassing the switch in the computer box that you had to re wire

Also ...... The PC inside a Pinball 2000 game always runs at 120v AC as it gets it's power from the transformer in the pinball cabinet. So if you are in a country that uses 240v DO NOT plug in the PSU directly to the mains socket with a PC mains lead. If you need to run the computer out of the game to do diagnostics on the motherboard, check that the switch on the back of the PSU is at 240v before plugging in into the mains! Also remember to set any PSU back to 120v before installing it in the game and powering up the pinball machine.

I thought the original PS was hooked up in that way.

I would still try plugging the new power supply into the mains to be sure that the transformer in the machine is not causing the problem. if it still does the same thing with it plugged into the mains then you can cross that off the possible problem list.
We don't now what the max wattage load is for the 110v winding on the transformer is so the new power supply being of a higher wattage could be overloading it and the voltage could be dropping enough to interfere with the power supply. It will depend on how efficient the new power supply is.

Is the new power supply designed for 110 and 240v or is it dedicated 240v?

All sorted, I purchased a thermaltake 500w PSU with a 110/240 switch on the back and it worked.

It seems that the Automatic converting PSU's do not like the RFM, I tried 2 Antec 500w auto switching PSU's (2 differnt models) then another cheapish auto switching one as well and they all gave me the the reboot at different stages of pressing any buttons on the RFM.

I then tried the thermaltake with the 110/240v @ 110 switched on the back, installed it all again for the 50th time   and it hasn't skipped a beat since

Well done.
