Is A Pure Sine Wave UPS Required for Corsair TX 750 or TX 850 Power Supply

[rootchand]

I intend to build a computer with among others, a power supply from Corsair such as TX 750 or TX 850. Would I require a pure sine wave UPS or would a normal one do?

My Likely System Specs:

1. Asus M4A79-T Deluxe Motherboard.

2. AMD Phenom II X4 955 CPU.

3. Sapphire HD 4890 Vapor-X 1 GB Video Card.

4. Corsair 64 GB SSD.

5. Western Digital 750 GB Sata Hard Drive Drive.

6. 8 GB (=4x2 GB) Corsair DDR3 1600 RAM.

7. Cooler Master HAF 932 Cabinet.
