JT0089 Posted January 14, 2013 Share Posted January 14, 2013 I just finished a new build, here is a summary of parts: i7-3930k @ 4.8 Ghz 1.410v 16GB (4x4GB) of Corsair Vengeance DDR3 1600 AMD 6970 Corsair h100i 1 HDD, 1 SSD, and 1 blu-ray drive Corsair TX650M. I have noticed whining noise coming from my PSU (which I think can happen to any PSU). I wonder if 650w is enough to power this PC. I have read that my overclocked 3930k can pull nearly 500w on its own. Plus the 250w that the 6970 can use. Quite frankly I am amazed my machine is running if the numbers I have researched are true. I have not had any stability problems so far... but for the amount of money I have in this computer I would not want the power supply to take out any components if it fails from being overloaded. So if you guys agree that I should upgrade I was looking at the AX850 or HX850. One more thing, I was hoping I could use the Corsair sleeved cables I just bought which are HX/TX compatible. Does anyone know if these cables should work with an AX*** PSU. Thanks Link to comment Share on other sites More sharing options...
peanutz94 Posted January 14, 2013 Share Posted January 14, 2013 That PSU is more than enough to power that build. I have read that my overclocked 3930k can pull nearly 500w on its own. I'm not sure where you read that but thats not true. No where close as a matter of fact. You can download software to see how much your system actually uses under load. But it's no where near that. I doubt your whole system would pull that much while at 100%load. If the PSu was underpowered , you would be having stability issues for sure. Upgrade if you want, but it's not needed. One more thing, I was hoping I could use the Corsair sleeved cables I just bought which are HX/TX compatible. Does anyone know if these cables should work with an AX*** PSU. No, they are completely different cables. Link to comment Share on other sites More sharing options...
JT0089 Posted January 15, 2013 Author Share Posted January 15, 2013 This is the article I had found. http://www.tweaktown.com/reviews/4435/intel_core_i7_3930k_lga_2011_cpu_review/index8.html They must be referring to the whole system. Thanks for the reply. Link to comment Share on other sites More sharing options...
peanutz94 Posted January 15, 2013 Share Posted January 15, 2013 I had to go back and re-read that article, but that is entire system power draw, not just the CPU alone. And those would be at 100% load which you would not meet rarely unless your running Prime95 or something like that. Link to comment Share on other sites More sharing options...
