80 Plus @ 300w or 80 Plus Bronze @ 450W?

The SG05 case is available with two PSU options: - 300W at 80 Plus efficiency - 450W at 80 Plus Bronze efficiency My plan is to stay very far from those levels, most likely around 100W or so. Given that both are overkill, which PSU would for normal operation be preferred (less noisy)? - Does higher ...

Re: DH77EB + I5-3750k Combination Low Power

I'm thinking about the exact same tradeoff as RHN! - Undervolting a 3570K with a non-Intel Z77 board or running e.g. 3575S at stock settings with a suitable Intel board. I guess one bonus of the 3570K choice is that you can adjust and adapt it according to power requirements or cooling. Perhaps it t...

Re: Power draw during boot when undervolting?

Sounds great!

I know Intel motherboards are known for low power draw, too bad they don't have an alternative that support undervolting the CPU. My guess is that I can make up for the difference in motherboard efficiency by running the CPU at a lower voltage.

Re: DH77EB + I5-3750k Combination Low Power

@cbutters: Any chance you can measure the power draw during boot and BIOS POST? Is this influenced by the "low power savings" setting in BIOS? I am looking at running a similar setup with a very small PSU. Once undervolting kicks-in I have little concern, but the boot and BIOS step feels sort of out...

Power draw during boot when undervolting?

If a CPU is undervolted/underclocked, does this also influence peak power draw during boot, or is the BIOS setting applied a bit later on? A 3570K has a 77W TDP but can be undervolted/underclocked to reach similar thermals as a 65W 3575S. But would there still be a good difference during boot? My re...

Re: TJ08-E, SG05 or other options?

That would depend on the cooling performance reached. If there is room for OC without more noise - sure. But I could also consider undervolting and/or underclocking, if that is needed to get a reasonable quiet setup. Noise level would come before performance, to put it in another perspective. Do you...

Write endurance of flash-based SSD is the most common "myth" of that particular market segment. While they *do* have a limited number of writes the actual life span corresponding to those writes will most likely never be an issue.

Unfortunately performance is less than stellar on most non-SSD flash. You can get 266x speed compact flash, which is decent, but only up to 8GB. That particular one isn't the fastest around, it's cheap. The 266x stuff has quite similar performance claims that I've seen out of the more disk-like pac...

What I find really interesting is the enormous increase in write performance when going RAID0. Does anyone have a good reason for this?

But if some of that write performance slowly trickles down to consumer HW things would start to get REAL interesting. The mai...

In this case you are most absolutely right about 2 vs 1, since both are good 120mm ones.
For me it was a choice between (semi-noisy) 80mm chassi fan, 92 mm CPU fan and good 120mm PSU fan.
Just a side note.

Well, it depends on the kind of HW you plan to put in. If the components are cool enough you might get away with using only the PSU fan to move the warm air out of the case, and not using any case fans at all. My current HTPC config uses that approach without temp problems. I guess it is a question ...
