Asic Cube switches off after short time

[kovert]

I have a problem with my cube

I have taken it all apart and tightened the heatsink screws and re seated the boards

It runs off a Corsair cx750 M

It will run for a undetermined time and re set itself ( Here a clicking sound ) Exact same sound as when it starts on

Normally runs for around a couple of hours before this happens

There are no errors on the chips all say 0000000

Running at 93% efficiency

I know a few of you are having the same problem but I couldn't see the cause or solution to this If anyone can help me I would be most gratefull

There's your problem.

Mine wouldn't work at all off my Corsair, or off an old Dell PSU, or off a 30A bench supply.  It does work fine off a cheap OCZ 600W PSU, though.

power ... some PSU seem to be a bit fussy - try another one

Hmm I was recommended the 750 I did try a 450 before and that blew up straight away

People on the forums say they run 2 off the 750

what would you recommend?

Thanks

A lot of people run them off the CX750.  Mine doesn't work off my CX750 at all.

Try and find a single rail PSU, or one that has 2 rails of at least 25A a piece.  The OCZ 600W I have has two 25A 12V rails, and it works fine.  It'll actually run the Cube off one rail at Low speed.

It's a OCZ ModXStram Pro 600W (OCZ600MXSP-UK).  It was the cheapest 'decent' PSU I could get off Amazon.
