Performance Tests

Considering that the test system draws a lot of power, I'd say the Vantec ION VAN-400B handled the load satisfactorily. While the 12V rail did dip to 11.82V, this is within fluctuation specs. Serious dips in power could the route cause of spontaneous reboots your PC, but differences of +/- 5% are typically expected, and should not cause that type of problem.

Whenever someone talks to me about computer problems, one of the first things that I do is ask about the power supply they're using.

Those who know me say I have a vendetta against cheap power supplies, but I don't see how anyone wouldn't be after seeing all the dead systems they have passed my way over time.

Power supplies are probably one of the most important pieces of the computer, yet most people don't give them much thought.

There's a saying "prevention is better than a cure." I'd say that applies extremely well when talking about computer power supplies. Vantec impressed us last year with their Stealth power supply, and with a retail price of just $80 CDN ($59 US) for the new Vantec ION, there should be no excuse for anyone to pick up a generic power supply. You may save $20 by doing so, only to spend another $800 later on to replace all the hardware that could be fried when and if a poor quality power supply blows badly.

The ION VAN-400B performed well in our system stress test, and while the 12V rail did dip down to 11.82V, the change was within fluctuation specs. With its long cables, ten molex connectors, two floppy drive power connectors, and two molex to Serial ATA power connectors, the 400W Vantec ION is power supply should be able to satisfy the needs of every user. Team that up with its economical price and the choice is an easy one.
