3rd Dan Black Belt Test

Author: Gabriel Torres Date: August 18, 2009 - 1:08 PM PST If you follow my website for long enough you already know that I train Tae Kwon Do since 1992 and I was about to test for my 3rd degree black belt. The exam was last weekend and it was really good. I posted some videos on YouTube, the highlight was definitely the breaking number four, where I had to break 13 boards with one strike (my hand is doing fine, by the way). Besides the four breakings and four forms (Poomsae), I have to perform several self-defense drills, sparrings (I uploaded the most difficult one, which was of me against two other guys). Now I have to train really hard to move to the next rank, 4th dan, which is the first "master" level. I hope to be able to test for my 4th dan in 2012. BTW, the window below is a "playlist", so you can see all clips in sequence or simply choose the one you want to watch.

Corsair Addresses Noise Level on our HX750W and HX850W Power Supply Reviews

Author: Gabriel Torres Date: August 7, 2009 - 12:52 PM PST On our reviews with HX750W and HX850W power supplies we've seen a high noise level on the +5VSB (standby) output surpassing the 50 mV limit while the power supply was delivering 20%, 40% and 60% from its maximum capacity. Below you can see the screenshots we got with HX750W during tests number one (20% load, i.e. 150 W, with +5VSB delivering 1 A/5 W), two (40% load, i.e. 300 W, with +5VSB delivering 1.5 A/7.5 W) and three (60% load, i.e. 450 W, with +5VSB delivering 2 A/10 W). During tests number four and five noise was below the maximum allowed. click to enlarge Figure 1: +5VSB during test one. click to enlarge Figure 2: +5VSB during test two. click to enlarge Figure 3: +5VSB during test three.  Worried about our findings, Corsair tested HX750W on a Chroma 8000 load tester (a far more advanced system than our SunMoon SM-268) configured with the same load patterns we used. The results for +5VSB noise were very different, as you can see on the screenshots below (maximum noise of only 13.8 mV). The only explanation we have is that somehow our equipment interfered with the outputs. This way any criticism regarding the +5VSB from these two power supplies we posted on the past should not be considered. click to enlarge Figure 4: +5VSB during test one, Corsair testing. click to enlarge Figure 5: +5VSB during test two, Corsair testing. click to enlarge Figure 6: +5VSB during test three, Corsair testing.
