Hey, I've been using TX950 since for 3 years now no problems at all, but recently i installed a UPS and when it swicthed to UPS psu starts making "sshsshshshsh" (his) sound. Every thing is runing fine but that sound making me crazy. Iam very scared.
Asus p55 Maximus iii
Corsair Dominator 8gb 2x4gb
2x2tb 7200 RPM HDD
Coolermaster HAF932 advanced case
Then it sounds like the transformer in the Corsair is having issues with the voltage level from the Modified sine wave coming from the UPS. I would probably not run the system on that UPS or eventually you can blow the PSU.
I agree with Eric. Newer, higher-efficiency PSUs really need pure sine wave UPSes. However, the modified sine wave UPS that you have is intended for systems with older, lower-efficiency PSUs that provide much less power output than their actual from-the-wall power draw.
Unfortunately, good pure sine wave UPSes can cost nearly half as much money as what you spent for your entire PC.
I asked Corsir's support they also mentioned about Pure sine wave. So i think i may switch the PSU b'coz i can't change the UPS it cost almost double the PSU and it has 4/5 Hours of backup.
I tried UPS on the CoolerMaster Silent Pro RS850 (borrow from a friend) it doesn't make any sounds at all,,,, This PSU would be good.
