Today I'm looking at the 3rd generation Antec TruePower power supply; The Trio. It's ATX12V, and it's more efficient than the previous models. But does it hold up like the old Channelwell built units? We'll find out today!
Inside the box with the power supply, we find a manual, a power cord and four mounting screws.
As I look at the finish of the Trio, I feel as if I had gone back in time. Back to a time before shiny finishes or sleeved cables. I picture myself sitting on a stool at a bench in a computer store in Tampa, waiting for Windows 95 to boot up. In the background, the Ron & Ron show are on 95ynf and the postman just delivered another volume of ST:TNG on VHS from Columbia Home Video. Dammit, Jon! Snap out of it!!
One thing that does bring this PSU into the new millennium is the use of a 120MM fan. This should keep things much quieter than the 80MM fans of yesteryear.
Type of connector:
True Power Trio 650W
2 x 2 12V connectors
2 x 3 PCIe
8-pin Xeon/EPS connector
6-pin Xeon/AUX connector
5.25" Drive connectors
3.5" Drive connectors
SATA Drive power connectors
Fan only connectors (thermostatically controlled 12V only)
Other than the fact that the Trio has an 8-pin, the cable count is really the same as a True Power 2.0.
Now let's take a look at the label.
True Power Trio 650W
Max Combined Watts
No information on combined 3.3V and 5V were available.
Separate +12V rails typically means that different connectors have different +12V sources. Although most power supplies have one single +12V source, this source is often divided up into smaller "rails" that have limiters on them that prevent overload and somewhat isolate the rails from each other.
When there are two +12V rails, figuring out which rail goes where is easy. The CPU is typically on it's own rail, while everything else is on the other. Sometimes a manufacturer may split up a pair of PCI-e connectors across two +12V rails. For PSU's with more than two 12V rails, one would typically find that the manual tells the user what rails go where. Unfortunately, the Antec Trio's manual doesn't have such information.
Plan "B" is to look for a color stripe on the yellow +12V leads coming out of the power supply. If you find a few yellow/blue wires and a few yellow/black wires, then you know those are different rails. I thought I was in luck when I found some stripes on the Trio wires, but those stripes didn't make much sense....
