Coolermaster GX 750W ok for this rig?

[dhicks19]

Hi all, I bought the HAF X case and it came bundled with the CM GX 750W psu.

My system specs:

I5 2500K @ 4.6ghz
asus p8p67-m pro
corsair vengance 8gb ddr3 1600 2 x 4gb
2 x amd 6950 xfire flashed to 6970 bios
antec kuhler 620
CM GX 750W psu
1 ssd
1 sata hd
1 disk drive
5 fans

I was wondering if the psu is ok to power the system, have not had any problems with it up to now, however when like loading a graphics benchmark with fans at 100% you can hear a dip in speed when load is applied and when exiting the benchmark they return to normal sound. Not sure if this is normal?

Cheers

Happen to know the exact model number of the GX 750 you have? The RS-750-ACAA-E3 failed pretty much every review for having out of spec ripple on the minor rails once above about half load. The RS-750-ACAA-D3 hasnt had a real review yet so its hopefully better but i would avoid loading up the RS-750-ACAA-E3 to heavily or its going to start killing things slowly.
