I'm glad you trust it. I've been working with power supplies and building systems for 25 years or more, more actually, and wouldn't trust that PSU without knowing
who the OEM for it is.
What it's rating label says and verifying it with a known reputable testing site
who the OEM for it is
what the internal platform is based on
and oh, did I say "who the oem for it is"?
Heh. Seriously, people trust Corsair, Thermaltake and Cooler Master, who are MUCH more well known than Insignia, and all three, among a lot of others, have some seriously crappy, dangerously poor units out there. I'd be intensely interested in safeguarding my GPU card, motherboard and CPU from a dangerous PSU that's an unknown factor when there is so much potential for damage to your hardware with a low quality unit.
You should probably educate yourself on the inherent risks of using a low quality or off brand power supply by reading the very important information at the following links. Or not.

And watching this. These were "brand name" units from well known trusted vendors too. Unfortunately, they were also crap. It's rather funny that Corsair made the video, since they have so many crap units out there.
