Do I need more power

[Freefor]

Okay, I hope I have this in the correct thread. However, I just odered parts for a new machine build and now, I am. Worried that my PSU is not going to be enough. My build is,

GPU: SAPPHIRE 100354OC-2L Radeon HD 7870 GHz
PSU: CORSAIR HX Series HX750 750W
Mother board: ASUS SABERTOOTH 990FX R2.0 AM3+
HD: Seagate SV35 Series ST2000VX000 2TB 7200 RPM
CPU: AMD FX-8320 Vishera 3.5GHz (4.0GHz Turbo)
Memory: Crucial Ballistix Sport 16GB (2 x 8GB) 240-Pin DDR3
COOLER MASTER full tower: 1 140 rear fan, 3 230 fans
Optical drive: LITE-ON 12X BD-R 2X BD-RE 16X DVD+R 12X
SSD: sata 3 6gig

Again sorry if this is in wrong thread, and hope for feed back thank you.

No. You actually have much more power than your build will use. 500w Would have been plenty.

You definitely do not need more power.
750W should serve you just fine.
