But i do agree paying top $$$ for a very quiet PSU and end up noisy its not worth the gamble.

If i were buying a sub 600W today, i would probably make the effort toward the Kingwin Striker 500 or Rosewill Night Silent 500, it can still deliever 600W just will not pass the Platinum but Gold certificaiton, its been reviewed by SPCR and both times came perfect scoring, even has comments like even quieter than the new passive X520 platinum. From the SPCR review,
Quote:
This sample produced virtually no audible electronic noise under ~200W, and at full power, its electronic noise was lower than all but the best of three 520W Seasonic Platinum samples I tested.

It was reviewed a lot of places, and came really out good.

I would just ensure that your case has positive pressure so you know some air will exit where the PSU is so it cools itself and doesn't become an intake for dust.

that looks like my choice right there thumb.gif

just wondering, would a 500w PSU such as this handle a 7970 (8970 etc..) & a decent quad core cpu @ 4.0 ghz ? with a few SSD's and a fan or two

Yes, definitely. It takes quite a lot of ivy bridge overclocking to even eat 150W

If you want a very silent PSU the Be Quiet Dark Power Pro P10 is pretty much one of the most silent units you can find

Well according to AMD webpage for the 7970
Quote:
500W (or greater) power supply with one 150W 8-pin PCI Express power connector and one 75W 6-pin PCI Express power connector recommended.
Personally i think they over budget it, due that the average PSU on the market isnt as stable as the high quality PSU from Sunflower/Seasonic/flextronics. But either way you are in line with their minimum requirement, still the PSU can deliever 600W just wont be platinum efficient, but still be as a gold rated psu, so it even has some headroom for what AMD asks.

Techpowerup 7970 Review has a maximum consumption of 270W,



So you still have at least 500-270 = 230W for the rest of the components, or 330W on gold rating. I doubt any quad from sandy/ivy/haswell (none E) will consume more than that OC @4ghz, fans are like 5W and ssd is between 1 and 5, specially the new samsung 840pro that has been tweaked in consumption, so i would assume you will be fine. Power consumption has been also dropping with new gens, so unless Nvidia/AMD go ballistic, i expect next gens to consume even less.

I was pointing out the 230W to stay with the range of paltinum, but the PSU can deliver 600W just as gold rated so 330W will be the difference. Or you were asking something different?

All gold PSUs will deliver gold if they are properly rated from 20% to 100% as specified in the 80PLUS specs. It's written there.
All specs have to meet a certain level when at any power level from 20% onwards

Take it as whatever you want, personally i see it more as marketing, they market it as 500W platinum PSU that can be overloaded to 600W and stil meet the gold rating.

Thanks for the info Abula. Also Shilka the be quiet is one i have been looking at for a while, i think having some air flow even the most minor of drafts is sensible near power electronics where natural convection can be blocked, in my case which it might? the build is for a silverstone FT03 and the psu placement is unusual and the top and right sides are covered.
