Testing & Conclusion

As Tech Critter do not own any industrial grade load tester to perform intensive tests on the power supplies on hand, we will be performing tests from the end user's angle. We've mounted the be quiet! Straight Power 10 600W on our Vector Bench Case and have gone through numerous tests which involves stress test and overclocking various hardwares i.e: Intel i7 4770K, Intel i7 4790K, AMD A10-7850K, AMD FX-8320E, AMD R9 290X, AMD R9 280X, Nvidia GTX 980, Nvidia GTX 970, Nvidia GTX 960, etc. 

Glad to say that we did not encounter any issues throughout all the tests conducted - the PSU fan did a wonderful job not only on cooling but acoustic as well; no coil whine issue found when the system is stressed with stress test and benchmark utility.  

Aside of the higher cost, we can't find anything bad of the be quiet! Straight Power 10. Really.
