Antec TruePower 2.0 430
430W ATX12V 2.01 Power Supply

Market Price


As a general rule, Antec power supplies are both inexpensive and widely available, which makes them a good starting point for first time buyers. A user who is smart enough to avoid the unbranded $20 power supplies that computer shops sell to the unwary, but isn't interested in wading through the technical details often ends up getting an Antec just because they are generally well-regarded and easy to get hold of.

The TruePower 2.0 430W is part of Antec's midrange line, so it makes up a large portion of Antec's sales. So, what are you getting when you put down your hard-earned money for a TruePower 2.0? Antec promises "tighter load regulation" and "dedicated output" among other things, but few first-time buyers are likely to know what these are, let alone why they're important.

Of particular interest to SPCR is the level of noise that is claimed: 21.3 dBA "measured at an independent lab using ISO 7779 standard". That's pretty quiet, but a single number rarely tells the whole story. Can the TruePower 2.0 stay quiet even through our strenuous test procedure?


The TruePower 2.0 looks quite unspectacular. The unfinished steel has a utilitarian appearance, suggesting the TruePower 2.0 is more at home in an office workstation than a gaudy gaming rig. The only visual ornamentation is the brass plating on the wire fan grill.

The steel casing is cosmetically plain.

Aside from the exhaust vent on the rear panel and the fan intake on the bottom, the TruePower 2.0 is completely sealed. Any airflow must enter via the bottom, and exit via the rear. This configuration should make it easier to design system airflow, since is only one intake and exhaust to deal with. However, the sealed design does nothing to encourage airflow in the farthest corners of the power supply, so the PCB will need to be well laid out to avoid the possibility of overheating.

A gold-colored fan grill is the only concession to aesthetics.

In comparison to most high-end power supplies, the exhaust grill is somewhat more restricted due to the square grid pattern of the air holes. Airflow would be less restricted if a honeycomb grill had been used. That said, it is still pretty open.

The stamped exhaust grill uses square holes.
