I see, so I should go for a high quality UPS then. I will try to fit it on my money budget, because it is already very adjusted.

Ooops, sorry, so common here to call them SAI = UPS (Uninterruptible Power Supply).

My apologies.

Hopefully, someone has something to say about this. I think it is another important point in this forum, because there are lot of people building low power home servers, and a SAI is always welcome to help them and no to lose information.

I am thinking in a similar project than you. I want a NAS-Home media server computer, mainly for streaming media and storing all data at home, because I have several computers and I sometimes become mad looking for something. I also started looking for a good atom mobo, but after a few research, I a...

SAI? Does it worth?

Hi. As far as I am planning an upgrade of my HTPC, I am also thinking in a SAI, because the quality of the energy provider where I live is more than poor. Every time it starts to rain, the electricity "goes off". Till now, I haven't had any problems, but I would like to make an extra protection to m...

Well, I think that 5w of difference is really noticeable when we are talking of 50w, because it is a 10% of the total. That's not an effective way of thinking about power/heat differences. Looking at only % differences, it's very easy to forget the reality: 5W is 5W -- never mind what the % differe...

However, I must be mistaken about the numbers if you are right, I will re-check that. However, I am planning in buying the PSU with other components next week. Do you know where can...

Forget picopsu and get the fanless seasonic that was just reviewed here. It has great efficiency at low loads and is a complete solution that will make your troubles disappear. That is a nice PSU, but my system is 50w idle, and that is less than 20% of this PSU, so the efficiency would be ver low. ...

You could start with one Winmate 130 watt supply and a 220 watt brick and add second Winmate once you add HDD's. That's how I am powering my HTPC. The 12v supply from the Winmate is higher quality than a pico psu in any case. See this link for a how-to: http://www.silentpcreview.com/forums/viewtopi...

I don't get it how you got from those charts that WD is the worst - it's exactly the opposite. 3.51W for RE2-GP 2TB vs 4.10 for F2 EG 2TB, and btw, at wdc site you have the specs for power consumption. That version of WD cost nearly double than the samsung. Are not in the same league. The other WD ...

Great, that means that WD are better HDD when computer is starting, but... What about the continuous use? Because the computer is going to be nearly 100% of the time ON, and WD are worst at idle and working consumption than the Samsung Ecogreen (all 2TB drives), at least, I read it at Tomshardware: ...

The main problem is not idle or load power usage, but the startup power usage. Each of your 3,5" hard drives will take ~2A on 12V rail to start up = 6A of 10A peak load (max 60 secs) spent just on hard drives. For WD20EADS it is 1.75A for example. So you are right at the edge of what is acceptable ...

Mediacenter + PicoPSU

Hi. I am thinking in upgrading my mediacenter with several new parts. My main concern is about the PSU, which I have read is the key to low the power consumption. I am not sure about the capabilities of these kind of psu to manage with several HDD, so I ask for some help about this problem. My compu...

Hi!! I appreciate your answers a lot. Maybe I was focusing too much in upgrading and the short solution would be some "modding" as you propose. After posting, I started to make some tweaks at Windows energy configuration, and I was able to low the "idle" power to 52-55 w (turned wifi and usb to maxi...

I am trying to build a home server basically for NAS, some FTP, and sharing media (music and videos). At this moment, I have a Zotac with Atom N330 and Nvidia 9400m onb...
