5 Power Supplies Get the Full Juice Treatment

Hiper Type R 580W

This device from Hiper is already well-known to us. In our live stress test, this power supply survived a difficult and demanding 24-hour test. Its only weakness then was its (minus) -12V rail, whose voltages climbed unacceptably high under heavy load conditions. Though this rail is only seldom used in PCs nowadays, and has a high +/- 10% tolerance, we still couldn't countenance taking liberties with the ATX12V2.0 specification. Hiper has subsequently improved this product, and re-submitted this PSU for further testing.

Connector covers keep dust and dirt at bay, and protect the contacts. This replicates standard practice in avionics.

Clever adapter cables save room inside the case.
