Zotac H55-ITX Review - The World's First mini-ITX H55 Motherboard

Board Layout
Expansion is inherently limited on a mini-ITX motherboard and ZOTAC decided to populate this lone spot with a PCIe x16 slot. Two DDR3 memory slots are available as well. It is worth noting that the CPU socket is actually located below the chipset on the H55-ITX.
Moving to the I/O portion of the motherboard you can see that Zotac did not hold back on the USB ports and by offering a total of 10. Two wireless antennae and a CMOS clear button are also available. For the first time on the Nehalem architecture we have a motherboard with integrated video outputs. On the Zotac, the available outputs consist of HDMI, DVI and VGA (via a DVI-to-VGA adapter).
An abundance of on-board SATA ports are provided by the P55 chipset. ZOTAC has also placed a hard drive activity light directly to the left of the SATA ports. The front panel connectors, fan headers and BIOS chip are located on the front of the motherboard. The mini-PCIe slot for the wireless module can be found between the RAM slots and chipset.

Actually, very not wrong.After a quick search, it looks like PCP&C 610W is only about 50% efficient at 30-40W (AC power) and about 70% at 70-60W.
This means the DC idle/load wattage numbers on the IGP are ~20W/50W. With a power supply rated at ~85% in that region, the measured power would be ~25W/60W, which is hugely different from the stated 35/76W - 30% "error" on the low end is pretty crappy.

really? tomshard was able to get idle power down to ~25wattshttp://www.tomshardware.com/reviews/25w-performanc...">http://www.tomshardware.com/reviews/25w-performanc...
now whos wrong?
have an address I have some crows pie to ship you.

I'd rather use a bigger power supply (possible a Zen 400W passive one) and have the system use 40W instead of using that 220W power supply tom's hardware uses, with a 40 mm NOISY fan, just to get 22W.The difference in watts is so small my cell phone charger eats it when I leave it plugged in over night to charge my phone.

So efficiency does or doesn't matter with you? Reality shows efficiency is all that matters as long as you have a stable and fairly priced PSU...michal1980 - Sunday, February 28, 2010 - link
efficeny matters. But I doubt that a 610w power supply is very efficent @ 30watts.have you ever heard of the right tool for the job?

Have you ever heard of gathering more evidence before jumping to conclusions?The purpose is a relative, not necessarily absolute power measurement. Think about it, they are not trying to match every possible system configuration a user could have.
For that, a 610W PSU is fine.
Further, you don't factually know what the right tool for the job is because neither Tom's, nor most reviewers, test long term with minimally sized PSU (that tend to fail prematurely when ran at a higher % of total load rating).
The right tool for the job is not really the most efficient without considering anything else. Think about it, if you really cared about efficiency you would turn off the computer you are using instead to post on the internet!

what false conclusion? Did you even look at this review?except for the 860 cpu, @ load the system used less then 110watts of power. Using a PSU thats rated 6x that is a waste, on both ends, idle, and peak.
PSU's certified for 80+, have tragets at 20, 50, and 80% of loads. The efficency of most, if not all falls significantly below a 20% load.
a quailty 200W psu would be a much better fit for most systems builds then any 600w psu.

Have you ever heard of admitting your original statement was wrong to just move on? Thanks for admitting efficiency does matter after your first blunder and then acting like a turd to defend it. No doubt you can find a better PSU, but at least now we know you're smart enough to realize efficiency does matter and you don't think it's pulling 610watts out of the socket or something. Have a nice day.michal1980 - Sunday, February 28, 2010 - link
wrong about what?a 610 watt psu is overkill for a system running ~30-150w.
If you cannot understand that, you are too stupid to even continue this disscussion
