What's happening is that when I powered up the
780 today it made this weird noise and instead of
the monitor lighting up it keep restarting or
whatever it was doing. I would see the internal
light flash and a noise and it's stuck in like a
loop (like a car turning over with a dead battery)
so I had to unplug it.

I switched the 780 monitor with the 8500 but it still
did the same thing. So it isn't the monitor.

On the front panel number 1 is blinking and number
3 is going on/off and each time the power button lights
up. It's like in a loop.


I seem to remember now that we discussed this before
and you recommended the Sparkle power supply:

Thoughts/suggestions?

Well, the prices are all out of whack. This is an older
group-regulated Sparkle design I used as a replacement for my
first computer. It's $87. It used to be a $50 supply. It
had a fair amount of inrush current when switched on.

This one is $100 and the wires might be slightly longer.
This one is Active PFC (i.e. nobody cares), and is also
more efficient and would run cooler (slight power bill
saving, less heat in room).

Strangely, the reviews on that one aren't perfect. There
are people with failures in the reviews. Serious failures.

This next one is $80 for the next six hours ($10 below intro price)

That one only has a few shortcomings.

You have to check there's room in the cutout in the back
of the computer, to make room for the ECO switch. You
want that switch set so the fan is always spinning (non-ECO
mode).

It's a 150mm long supply and modular, with stiff cables.

The combined power rating is 110W.

There are a lot of these to review. And it's annoying to
see products that when they failed, they took out hardware.

Of the three above, I might go with the last one. While
it's "on sale cough". Note that their mail in rebate
scheme is not worth using.
