for all you guys out there interested in facts about psu`s check out the
guru3d site (
www.guru3d.com) here is a qoute:
A PSU needs to manage the power demand in a very secure way otherwise it'll create instability throughout the system. That instability can result as crashes, freezes, underperforming software such as games that run poorly when the graphics card isn't fed enough power, and even resets or shuts down the system completely. Please do not underestimate the importance of the PSU.
(taken from a review on an OCZ ModXtream PRO 600 psu on guru3d.com)
I think that the guys at guru take the reviews very seriously and it is a trustworthy site to visit when planning on a new build or facing problems with your hardware.
here is yet another qoute taken from that review:
If you have a generic older power supply with an average 70% efficiency a 350 power draw (350/70x100) watt load would mean it is drawing 500 Watts of current from your wall socket while your PC only uses 350 watts, interesting eh? Yes, you loose 150 Watts yet are paying for that loss.
Let's do that math again, yet this time with a 80% power efficiency in mind: 350/80x100= 438 Watt. So that's saving 64 Watts over a 70% efficient product. If you have your PC powered on a lot , think about this theory and what it can save you in the long term.
Now if we estimate that today's tested PSU has a 85%-87% efficiency 350/85x100=412 Watt. We just saved 88 Watts by simply opting for a better power supply
any questions,anybody?
