Title: A4000T PSU - 250W enough?
Post by: X-ray on August 08, 2004, 09:42:43 PM

I am beginning to wonder whether the standard 250W PSU in the A4000T is enough for me.
I run it with three hard-disks and a CD-writer internally, and then the Cyberstorm has 128mb on it. There are two extra fans: one on the 060 and another backplane cooling fan.

So, should I get something better, like 300W or 350W?
What would happen if I added a fully-loaded DKB3128 board?
Has anyone ever changed their A4000 PSU?

I have the original A3000D power supply @ 135watts running my setup (see sig) 250 W should be enough.

I never had any problems with the original 250W power supply,
but I did go ahead and change it out in favor for a 300W Fortron PSU.
The Fortron 300W was the biggest AT supply I could find still
available that was affordable.  The only modification required was
to the P8 and P9 connectors.  Some of the plastic ribs on the back of
the connector had to be filed down. If you find a replacement power
supply that is reasonable, I say go ahead and change it.  Unless the
original is on its last leg, it should work fine until you find something you like.

I changed my A4000T PSU once, however it was to the same W rating.


With all that hardware, I do suggest you upgrade your PSU. AT PSU's should be fairly cheap.

Thanks for the advice, guys..


@ Bill: could you please tell me the model number of that Fortron PSU?
I assume I should be able to get it anywhere.
