Seasonic S12 330W
Performance:
Since this was a lower power unit, we installed the power supply in one of our
older server systems with specifications listed below.
| Hardware Components | |
| Processor: | Intel Celeron 1.7GHz (A) |
| Motherboard: | Gigabyte GA-8LD533 |
| Memory: | 512MB PC2100 |
| Hard Drives: | Western Digital 40GB IDE 5400RPM |
| Optical Drives: | 24x CD-ROM |

To stress the rails we ran glxgears and CPUBurn-In v1.00 for about 30 minutes and for idle we let the system run no active processes for the same amount of time. A Craftsman digital multimeter was used to record all of the voltages.
+3.33 | +5.00 | +12.00 | |
| Idle: | 3.25 | 5.10 | 11.91 |
| Load: | 3.26 | 5.11 | 11.90 |

Basically, the rails didn't budge at all. They are well within specification and rock solid.
Conclusion:
Overall this S12 330W has awesome features and performed very well. Thanks to the 12cm fan, the unit was also near silent during idle and also during load. We recommend this unit to enthusiasts looking for a good lower end power supply and we definitely recommend this unit for people looking to build silent systems that don’t draw more than 330W. Overall this is a very good power supply for people with lower end machines. If you are wondering how the S12 600W or 500W performs, we should be receiving a sample sometime soon so check back to see how it holds up.
