Re: A new inaudiable build for basic use

The samsung f4 is an amazing hdd. Why not the 2tb one; it was on sale recently for $85 for 2tb. I use the green 2tb for media storage and have a ssd for boot/os/apps. Even with your 5450 you're not going to use a lot of wattage. The 400W psu is more than enough (getting a deal on it is a challenge, ...

Re: A new inaudiable build for basic use

the issue with some of those psu (fanless) in a p183 case which has a relatively isolated lower bay where the psu resides may have inadequate ventilation as the vents for the psu are traditionally on the top of the psu and rear. However at energy sipping low loads the heat energy differential betwee...

Re: which psu for antec p183

So far we have 1 vote for seasonic x400 and 1 vote for antec cp850. BTW for cp850, the fan is PWM controlled. At light loads (<70 idle system where the system will be >90% of the time), the fan really has very little work to do and thus doesn't really move much air. OTOH, for x400, at such low loads...

Re: PicoPSU for a home server / NAS

stick a kill-a-watt at the wall outlet and see how much your current nas is running at idle and load and then decide the right size of psu to get.

In case someone is in the market for an intel x25m ssd 80gb. The egg is running a special (starting midnight tonight) @ $169 after rebate. I have this drive and is my fav ssd out of the three I have. The other two - 1 is a samsung slc, and a ocz vertex. intel ssd (for apps/boot) is far better.

As long as I stay under the total wattage is there a limit to the number of HDD I can use in a small nas powered by your psu? I imagine I'd need plenty of Y splitters for the molex/sata power?? How about multiple fans?

Very nicely done. I prefer spcr's reviews better than others commonly seen on other hardware sites. I just wish you'd do more. I like that you hit on two aspects that we're most concerned about - noise and power utilization. Looking forward to your 3 platter seagate caviar green 2tb review. A sugges...

There is also some speculation that intel will integrate usb3 so mb manufacturer's will not have to rely on nec chips for usb3.

The WD20EARS green drives actually come in two flavors with the newer ones modeled after the f4 with 3 platters of 667 each whereas the earlier model WD20EARS used more. Incidentally they are both called the same model. Perhaps this may partially explain the increase in vibration and noise. It is pl...

The mac mini can idle at 8-11w. DIY core i3 have achieved in the 15w range. I'd post the link but it won't let me

Clearly a picopsu is more than enough for these types of builds.

Yes. I have an old c2d with a discrete (radeon 5850) and 3 old (not power efficient) hdd + 1 green hdd + 1 ssd and peaks during boot / heavy cpu usuage at about 250 per killawatt.
