Antec Basiq BP500U is a pretty decent mainstream 500 W power supply that can really deliver its labeled power at 48º C – in fact we could pull up to 640 W from it.

Efficiency was between 81% and 83% when we pulled between 100 W and 400 W from it. At 500 W efficiency dropped a little bit below 80%, as it is normal to happen with products from this class.

Voltage stability was one of the highlights from Basiq BP500W, with the main positive voltages within 3% of their nominal values – i.e., closer to their nominal values than required by the ATX specification.

Ripple and noise levels were low at all times.

In summary, if you are building a basic or intermediate PC and want a power supply that will do the job and, at the same time, provides decent efficiency, great voltage stability, low ripple and noise levels and protections that work, you can save money by buying Antec Basiq BP500U.
