is cooler master gx 750w enough and ok for me?

[nix253]

hey guys i just got this power supply with full confidence that it's good enough for the 6870 crossfire upgrade that i'm gonna do in coming days on my i7-860 build with asus p7p55d deluxe...

now i'm seeing a bit of negative responses from few user's on net n just a couple of pro reviews like from johnnyguru n hardwaresecrets that gx750 doesn't live upto it's expectations which is making me a little nervous...... i'm not gonna be OCing any component most probably n even if i do it'd b my cpu but would do so only upto like 3.2-3.4 ghz.... so please tell me am i alright down the long road with this PSU?

Those two give it a good rating...but as you noted, JohnnyGuru's review is less than glowing.

"Summary

Coolermaster has a decent 600 watt unit here. The unit does pretty well for stability and efficiency, doesn't get very loud, and... what? It's a 750 watt unit?

Facepalm.

Past Coolermaster units have done pretty well here in the lab, and I'm puzzled that this one has done so poorly. I hope that next time, if there is a next time, we'll have something worth getting excited about.

The Good:

* appearance
* enough cabling to handle anything a 750W unit can power
* somewhat shallow depth

The Bad:

* cannot handle heat at 750 watts
* ripple issues on the 3.3V rail
* questionable capacitor quality

The Mediocre:

* voltage regulation


I always default to JohnnyGuru's PSU ratings. IMO, there are none better at putting a power supply through its paces and finding any weak spots.

Will that PSU be acceptable? Possibly...but a bit of googling shows it doesn't get many good reviews.

"Conclusions

Cooler Master GX 750 W looks like a good option for users looking for a mainstream 750 W power supply, however it has a major flaw that prevents us from recommending it: noise level at +3.3 V and +5VSB outputs were above the maximum allowed when we pulled 600 W and above from this unit. High noise levels overload and can even damage components on your computer.

If you are looking for a mainstream 750 W power supply our recommendation is still Seventeam ST-750P-AF, which is USD 20 cheaper than Cooler Master GX 750 W and provides better performance (namely higher efficiency and lower noise levels). Of course GX 750 W offers as advantages having four power cables for video cards and more SATA power connectors, but it is only safe to run this new Cooler Master unit up to 450 W."

but i'm gonna be ocing my cpu to just 3.2 ghz n just use the two 6870s in crossfire so will that demand too much power...power more than 600w? because after reading the reviews you just mentioned i guess it'll b safer to run it under 600w ....n when i saw the reviews of the cards' crossfire 2 6870s were running under 450w ..so does that include the power for mobo n other components too or not?
