DiY PC: Antec Truepower Trio 650W (PSU)

Antec Truepower Trio 650Now that I have a case, the Antec Nine Hundred if you remember, I needed to get it powered…adequately. I went through quite a bit of research to try and figure out how much power I would need, but in the end I found it more difficult…and inexact to do the “right” thing. It seems like analyzing power usage is easier after you’ve used it. So maybe I can figure out how much over-powered I am once this is all configured.

As my previous experiences taught me, I don’t skimp on power supplies either. I was interested in a rock-solid performer with as high an efficiency (power supplied versus power converted to heat) as I could afford. I was surprised by what I found. While there are some exceptions, the more efficient PSU’s available today are running at < =85% efficiency. Of course, there can be dramatic differences from the max load efficiency rating (usually the highest number) to a 50% load average. Regardless, I won't really know what I have until it’s under load and the Kill A Watt is monitoring it.

The Trio lineup from Antec isn’t what I’d call sexy. I’m only a little disappointed by that – the box art made me think I was buying a black PSU for my black chassis. It’s actually flat gray. The standard color for all PC components circa 1990. I thought about hitting it with some high-gloss enamel paint, but I’m not sure I want to void the warranty just yet. At 5 years, the purchase price included this notable addition to the Antec product. I could always mask it and paint it intact, but that makes me even more uncomfortable.
