Power supply unreliability

I don't have a problem with MC per say but I keep burning out power supplies
on my Tranquil AVA. I've just replaced it for the fifth time in two & half
years. Which I guess means they only last six months ...
The power supply currently is a DSA 90W 12 brick (Switchable 90W 12volt) and
I don't think it likes being left on all the time ... which of course is the
whole point of having a MC PC!
Tranquil replace two of them but aren't much help now, so I was wondering
would it be an advantage to get a power supply with a higher wattage? Say
120W?
And is it OK to leave 'brick' type power supplies switched on all the time?

TIA

It's a laptop? I've not seen a desktop with a brick type power supply.

In general, if the power supply is burning out, upping the wattage is a good
choice, since it likely means you're drawing more power than it can actually
handle. You could get one of those watt meters to find out the precise
power draw if it interested you.

The other thing is that they're heat sensitive... if you have it stuffed in
a closed off space with no ventilation, that will cause overheating, and a
significantly shorter life span. Getting a higher wattage unit will not
help if that's the issue.

Hope that helps?

There are plenty of them. Here is an example:

Yer but .... ... where can I get one that doesn't keep burning out if it's
left on 24/7?
