Power supply

Anyone else having problems with failing power supply?

My ormerod was supplied with an Ace 550w psu, but it seems to be borderline as it has shut down several times.
I am no expert in electronics but it is quite clear that the hot end fan slows down a bit every time the bed heater is activated, (normal?)
All the wires are checked, the bed works fine, it heats up to the correct temp and stays stable, so i am clueless.

Is the only option to upgrade?

There have been a few reports of the power supply shutting down, and RRP were investigating. Ask RRP for a replacement under warranty. With any luck they will send you an Alpine (the other brand they have been supplying), which has a higher current rating on the 12V supply.

It is normal for the fan to slow down a little when the bed heater comes on. I am currently using a Corsair CX430M instead of the Alpine that came with my kit, and the fan slowdown is much less, barely noticeable.

Til then i will try some other atx i have lying around the house, had a look and to me the RRP one seems to be all standard, right?

(To RRP: For future customer kits, ditch the cheap psu for one that can do the job, it may increase salesprice slightly, but totally worth it to avoid these kinds of complaints + sending stuff back and forth)

Check the current rating of the 12V supply on your other ATX power supplies. You need a rating of at least 20A, and a higher rating (e.g. 32A for the Alpine and the Corsair) will hold the 12V supply up better under load.
