Real World Testing

So, what do these excellent controlled results mean in a real world environment? To show this we take two steps. The first is to build a system which is appropriate to the PSU’s target market. In the case of the Platinum Series we assembled the following components:

Intel Core i7-990X CPU
Corsair H80 CPU Cooler
Gigabyte X58A-UD7 Motherboard
6x 4GB Corsair Vengeance DDR3-1600
1x Corsair Force3 GT SSD
2x WD VelociRaptor SATA Drives
Corsair 600T Case
Sony BDU-X10S Blu-Ray Drive

This creates the basis for an enthusiast system with significant power use. Added to this we have 2x20cm case fans and various USB devices (keyboard, mouse, Wireless-N) which draw additional current.

With the system set-up we then test noise, exhaust temperature and min/max power use on the 1000w sample, a current generation PSU and a comparable model from 12-18 months ago in real world use.

  Noise Exhaust Temp Minimum
Seasonic Platinum 1000W Idle 20.0dBA 21.5°C 275w
Seasonic Platinum 1000W Load 24.0dBA 25.0°C 812w
Hiper 1000W Idle 29.5dBA 31.3°C 288w
Hiper 1000WLoad 34.0dBA 40.0°C 831w

In the 1000w class there are numerous benefits to be seen when comparing the new Seasonic model with an older unit. Temperatures are far lower, noise levels too. Then as a key result the Seasonic powered system draws less power at the wall, reducing energy costs.
