Review: Hiper Type-R Series 480W Power Supply - PSU - HEXUS.net

Testing

Going by the documented figures in the manual, Hiper state the Type R will be ready within at least 100ms and no more than 500ms from startup for a 100% complete boot time. Ripple voltage limits are stated to be no more than 200mV peak-to-peak on the -12V rail, 100mV on the +5V rail, and 70mV on the +5VSB and +3.3V outputs. Let's now see how the theory translates into real-world performance.

Load Test Results

To test out Hitech's offering, we'll be running the power supply with a handful of devices attached while under intensive CPU, GPU and hard disk loads, and monitoring voltages using Motherboard Monitor. To give some numbers for comparison, the unit will be up against a 460W ENlight offering as well as a less powerful 350W Enermax PSU.

Hiper Type-R ATX 2.2 PSU
ENlight ENS-0246B ATX 2.03 PSU
Enermax 365AX-VE ATX 2.03 PSU
AMD Athlon 64 Model 3400+, Gigabyte GA-K8VT800 Pro motherboard
Corsair XMS3500 RAM 512MB
Connect3D Radeon 9800 Pro
IBM 13GB PATA HDD
Western Digital Raptor 36GB SATA HDD
2x 80mm case fans
Pioneer DVD-106S IDE DVD-ROM
Yamaha 40x IDE CDRW

To perform testing, 3DMark05 was set to perform a looped default benchmark run, while a SETI@Home unit was running on the CPU. Alongside all of this, 2Gb of data was constantly copied and then deleted between the two hard disks in the system. This setup was left running for approximately 30 minutes while measurements were taken.

So, let's take a look at how the unit fared.

+12V variance results

PSU	Maximum	Minimum	Adjusted Average
Hiper	12.20	12.20	12.20
ENlight	12.27	12.20	12.27
Enermax	12.07	12.01	12.01

+5V variance results

PSU	Maximum	Minimum	Adjusted Average
Hiper	4.69	3.88	4.23
ENlight	5.61	3.01	5.42
Enermax	4.09	3.25	3.55

+3.3V variance results

PSU	Maximum	Minimum	Adjusted Average
Hiper	3.23	3.28	3.26
ENlight	3.20	3.17	3.18
Enermax	3.25	3.20	3.22

None of the PSUs used here show particularly impressive results, and all have varying good and weak points. Concentrating on the Hiper Type-R on test here, to it's credit it has the most stable voltage on the 12V rail, not once shifting from 12.2V during testing. On average, it also gives the closest to its target voltage on the 3.3V rail at 3.26V. However, it does show more fluctuations than that seen on the ENlight PSU. Performance on the 5V rail is really the biggest disappointment, with large fluctuations being seen and not a particularly impressive average compared to the target voltage either. Overall then, not a bad showing from Hiper's offering, but nothing to shout from the rooftops about either.
