Type R Mk-II HPU-5K880 Exterior

The Hiper HPU-5K880 880W power supply unit is identical to the HPU-5B680 680W Type R Mk-II PSU is every way except power output. Both are available in black or blue reflective finishes, and both offer native cable connections.

Also identical among the entire Type R Mk II series is the reusable tub which contains the PSU. Once you install the PSU, the tub works well to hold any additional wire or devices that you carry with you.

Although the black on black appearance may do well to hide fingerprints and dust, I think that it would have been great to have the USB cables be equally as conspicuous. Since they connect directly into the motherboard USB output, there isn't much chance of hiding them. Hopefully Hiper can match them to the rest of the cables in future production runs.

Rounding out the back end is an standard-size master power switch. Active power factor correction replaces the antiquated 110/220 switch, and also adds a higher level of power efficiency to the product.

By maintaining a clean array of native cables, Hiper offers a very easy approach to cable management inside the computer case. The entire Type R Mk-II series of PSU's has a clear advantage over other power supplies that simply bundle all of the cables together into one major group.

All sides of the chassis (except the bottom) have mesh vents which help keep components cool despite the fans active cooling. I imagine that this is a glimpse of the future, because one day we will see power supplies so efficient that they require no active cooling.



# Voltage Monitoring via SoftwareRobertC 2010-05-18 22:26
Great work adding the electrical measurements to your PS reviews. I am curious about your opinions on and experiences with software power monitoring tools that are installed and run on a PC. Intel has in its Desktop Utilities tool a Hardware Monitor section which among other things, displays voltage readings of the +12, +5, and +3.3 DC rails, as well as the MCH and Processor voltages (labeled Vcc.) The seemingly real time digital display has a resolution of three decimal places (1/1000 volt.) Alarms can be set to warn of over or under voltage situations. In general, how do these programs work and how accurate can they be? Are any of them worthy of an enthusiasts attention? Thank you.

While the accuracty may not be to electrical engineer level, I would contend that some form of monitoring is better than none at all. So long as the software doesn't cause any problems, I'd say it's worth installing.
