I received my Winmate DD-24AX today and connected it to a spare PC, with all drives and other peripherals disconnected, but so for I haven't had a lot of luck with it. When I hit the power button the CPU fan spins for a second or so, but then stops, with no other sign of life from the system.
I'm using it with a Li Shin 0226A20160 AC adapter, which is definitely within the Winmate's required spec. I'd have thought that if the power brick was faulty it most probably wouldn't power up at all.
I'll test it with another system when I have the time, I've an old Celeron boxed away that still works, but I'd appreciate any ideas as to what's going wrong.
Edit: I tried it with my old 450Mhz Celeron and it powered up perfectly.
I have read the Low power system not booting with high efficiency PSU?!
sticky thread, but I assumed that this wouldn't be a problem. The old Athlon I used for testing, even with all it's drives disconnected, draws around 80W idle, and that isn't particularly low power. Obviously there's something funny with its old MSI motherboard. I have my fingers crossed that I won't experience anything similar when I try the DD-24AX with my main PC.
BTW, for anyone looking for an AC adapter for the DD-24AX, my 160W Li Shin brick (for a Fujitsu laptop) seems to work quite nicely, and is easily available. It has a nice long cable and a 4 pin connector with the correct pin layout to plug straight into the DD-24AX.
It's fanless, and from the look of it the 180W version is too. Plugged in with no load, my brick does make a small amount of noise, but not something you're likely to hear when it's on the floor behind a desk. Certainly nothing like the whining from a lot of other power bricks I've had to suffer over the years. At the Celeron's 45W-75W load it makes no noise, even with my ear pressed against the brick it's silent.
