I've got a KPI 250W DC-DC PSU.
If you consider doing an even trade let me know via PM.
I have been having constant trouble with the opus being unstable. At first it would not provide power to my system during standby so opus sent me a new one. The new one also has standby issue’s and reboots my PC if it has been on for more than an hour. What is the next best power supply?
In my opinion, the DSATX beats every other DC-DC PSU hands down, including the Opus 150w.
It has features that no other DC-DC unit currently on the market has, and a full 220w of power and is far more efficient, meaning it's using less of the vehicle's electricity to power the same wattage PC.
From a fiscal standpoint, I believe the DSATX is a superior value.
The DSATX with the brainstem to program it to your liking is US$201.74. ($189.99 + $11.75)
To get similar functionality with the Keypower 250W, you'd need the PSU itself for $198.00, a shutdown controller for $41.99.
You still wouldn't have thermal protection at the PSU or battery protection, and you've dropped $50 more.
That's based on prices of new equipment. I'm certain that if DJiK has a used one, it would be a lot cheaper than new.
