I have not had any cucsessfull overclock on the cpu, and the temperature of the gpu's are high enough as it is tongue.gif

And how can i controll how much wattage the psu will allow to spit out?

Well it's not a matter of that really, it's how much load and stress is going to the PSU.
You might well be running around 650w now with all the components you have connected and with the age / usage / general wear and tear of the PSU might only be outputting 655w now.
Unlikely, but it can happen.

It's a Cooler Master GX 750 and OklahomaWolf said it's basically just a 600W unit:

An error occured while manipulating the DB!
But anyways, the calculator indicated my pc needs a 625W while i have a coolermaster GX750w but when i plug my fourth hdd in my pc, the motherboard activated a failsafe mode to not "overwork the psu" when the hdd is in use...
So either it's my motherboard which has the limit at 625w for my 750w or the calculator is incorrect.
So i dont know.

That protection on the motherboard that probably got trip off has to do with the voltages. While Asus mobo are notorious with this protection tripping off even on an over-adequate, high-end unit, the GX750 is a poor unit that has shown to have poor DC quality output and voltage regulation. You shouldn't be seeing loads higher than 500w in any situation with your sig build in a typical working condition, except for during synthetic loads of Prime95 and Furmark/Kombustor. So a 750w shouldn't have any difficulty as long as it's a quality unit (even a 650w unit would be plenty), but that GX750 is not a quality unit and would replace it.

Don't use the 80+ certification as an deciding factor of purchasing a PSU. It is an aspect in choosing a PSU, but it doesn't determine the unit overall quality. You could have a highly efficient power supply, while it is poor in everything else. There's are also some who lie/cheated the 80+ certification, when a unit that supposed to be a bronze unit was marked up as a gold unit.

Check this thread out for some PSUs that are recommended. http://www.overclock.net/t/183810/faq-recommended-power-supplies

The math has been tweaked a fair bit for the next release (along with math being processed server-side so no client changes are required when we make further tweaks).

This.

 

sonarctica, it's like I told you before:  the 80+ certification is mostly marketing hype.  There are 80+ Gold power supplies that are complete junk and should be avoided at all costs.  For example, the 1100W ABS Majesty:

 

http://www.hardocp.com/article/2010/01/22/abs_majesty_mj1100m_1100w_power_supply_review/9 (the "conclusion" page)

 

If you go by the 80+ certification, then you may as well go by other trivial things such as the PSU's color, or even the fancy name given to the PSU.  The only thing that matters is what's inside the outer casing of the power supply.  The rest is just fluff (except, maybe, for whether or not it's a modular PSU).

 

Now, please don't get me wrong:  I'm not saying that the efficiency of a PSU is absolutely unimportant because it can be very important, especially if you're the one paying your electricity bill and you need to do absolutely everything you can to lower it - even if it means lowering it by just a very tiny amount.  For a situation like that, you'd try to focus your shopping on the most efficient power supplies.  Here's why:

 

Let's pretend that your system pulls exactly 500W from a power supply while playing Crysis 2 (stay with me here, even if you don't play Crysis 2 - I'm just making an example).  Here is how much power would have to be pulled from the wall outlet at the varying efficiencies below in order to deliver 500W to your system:

 

  • 80% - Exactly 625W
  • 85% - 588 - 589W
  • 90% - 555-556W

 

(Note:  This has nothing to do with a PSU's capacity.  An 80+ efficient 550W power supply will pull 625W from a wall outlet in order to deliver 500W to your system)

 

So as you can see, the 80+ certification is not as important as the industry is making it seem (it's marketing hype).  Not only that, but a PSU's quality can not be determined by its 80+ efficiency certification (as seen from the quick example of the 1100W ABS Majesty).  Unfortunately, the only way to determine a PSU's quality is by asking around and by looking at professional review sites who know how to review and test a power supply.  So, you'd also have to ask around to learn which review sites are good and which aren't.
