I haven't decided yet but I'll likely go for one with the best price and performance ratio.

Thank you all guys for your nice comments, appreciated.

Mayalogy: Anyway, there are lots of decent PSUs in the recommended list that are pretty darn quiet/silent @ 250W AC. How much do you want to spend?

Around 50-60 bucks. A quiet and efficient psu will just do the job.

Some time ago, I posted my build list already but made couple of changes on it, so here it is: p8z68 asus mobo seagate 7200 (and possibly a second hdd with 100gb or so for data backup) hd6850 8gb ram i5 2500 dvd-wr 1-2 case fans I don't think this build will be a resource hog so a moderate psu would...

What actually I was trying to find out that why there is such a big gap between the combined powers ie 504 vs 576. The second psu (corsair) delivers almost what it says on the label whereas in the first one (high power), the power drops down almost one-sixth of the total power stated on the label. T...

Guys iam stuck between two psu specs. PSU 1: 600W, has two rails with 30A each, combined power 504W. This has a bronze certificate. PSU 2: 600W, has a single rail with 48A. Delivers a total of 576W. 80plus. So, when taking the specs into account the second one seems to be more preferable as it provi...

Thank you guys for taking your time to explain the things. Appreciated.

Nearly all power supplies achieve their highest efficiency during 50% loading condition. says http://silverstonetek.com/techtalk_cont.php?area=&tid=wh10_005 which clearly contradicts with the statement in corsair's psu guide pdf file (%80) :D . Much as I respect Corsair products (I use more than a ...

What is your budget in this? If money is no object then the Seasonic X-400 or Kingwin STR-500 are both amazing. As you say money is no object, want to build a good system that should last at least 6-7 years. As for the 80% efficiency level, I think this relates to two different things. Ok I know th...

I highly doubt that a Z68-mainboard will draw 75w.

Even if I use the integrated graphics? Also did you take 80% efficiency thing into consideration when making suggestion?

Thanks for the hand guys. What components are in your system? Maybe if you can list them here then a more accurate suggestion can be made. GIGABYTE GA-Z68AP-D3 = 75w (just about) Kingston Hyper X (2x4gb) = so small i5 2500 = 95w 2*SEAGATE 3.5" 1TB Barracuda Sata 3.0 32MB Cache 7200Rpm = 20w ZALMAN C...

Hi guys, I'm upgrading my system and i am a bit confused about the psu power. My question is let's say that the maximum power consumption of the components at the full load is 300w. If the psu is 500w then does that 200w end up as a waste which is added to my bill as something I didn't use OR the co...
