BUILD Noobs first built - Info I used and thinking process

[Rand]

Well then go 350, there are several available.I didnt go Atx, that doesnt fit my case.

Ah great idea thanks!
I selected the Seasonic G-360, its twice as expensive but hey I calculated it should pay off in about a year

Whoa.. what kind of electricity prices do you ahve?! Most people will save only a few dollars a year on a gold over a silver or bronze, but the price of a gold is typical far more than a silver or bronze of the same.

Ah i dont think thats right;)
BeQuiet - 29€, efficiency at 50 % -> 86%
Seasonig G360 - 54,66 - >e at 50% -> 91%

So *if* they both had the same wattage then we could say that we have 5% efficiency discrepancy @50% Load (which is higher than you are usually), @20% its BQ85%/SS89% so 4%; 20% Load is ~60Watts so you will be >20 <50% usually.

So assuming you need 90 Watt, then the BQ will need 104,65 W to produce that and the Seasonic 101,12W
So thats 3,5W difference.
With 0,25€/KW and an uptime of 24/7 its €2,50/W/year -> so ~9€/Year savings -> After 3 years you'll get to a break even point.

The problematic point is to know in advance which load you will have and to find a PSU which peaks at your average (or even better: most frequently used) load.

 

[Thorsten]

Yes exactly I calculated with higher Watts and a bit highers prices as I am using renewable energy which is a bit more expensive.

Hey Guys

I started putting together the NAS and I noticed this silver ting on the keyboard.

It has springs and the left and right which I can push down on the it moves from side ot side when I push on it.

Does anybody know what it is?

Its not on the pictre of the motherboard on the manufacturers website as far as I can tell?

Thanks a lot

That is a heat sink, don't move it around of you will destroy the thermal connection, if you haven't already.

 

[Thorsten]

Thanks!

Just weird that it moves at all?! And why is it not on the pciture on the manufaturers website?

Very weird

 

[joeschmuck]

That is normal. Those type of heatsinks are to provide just enough heat dissipation, it's not perfect but it does the job. It also allows easy replacement of the chips since nothing is flat out stuck to them. On the backside of the heatsink you will typically find a rubber like thermal pad. It's been my experience that over time the thermal pad will ad hear to the three voltage regulators [in your case] (or chip it's sitting on) and become less pliable. If you move the heatsink after that period of time it will never create another good thermal bond so you are left with replacing the thermal compound with thermal tape.

I suspect the reason it's not shown on the manufacturers site is because they pulled one that wasn't completely built up for photos or they added the heatsink at a later date because they didn't realize it was needed. I suspect the first scenario.

Like Joe said, they probably used a pre-production sample for the photographs. It's common for those to miss things like heat sinks. Also, push-pin connectors aren't perfect but they're perfectly sufficient for chipset/vrm heat sinks. Just don't try to pull it or you'll have to replace the thermal interface material.
