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
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.
