The newer Kill-A-Watt's can accept your $/KWH and give you $ figure for a period of time. Older units (like the one I have) only report the instantaneous watts. I suspect both Newegg and Amazon have good users reviews to help you decide.

I am looking for the lowest max power usage and need advice. I have a Gigabyte H55 MB with a i3-530. Great MB and CPU but forget undervolting. Turns out the CPU dynamically undervolts as required using its 1-million transistor power manager unit. I got down to 1.0V with zero power difference. Below...

So how good is the 65W PSU?

I have no interest in the case, slim DVD. But I have a Foxconn mini-ITX/Atom 330 with a 5.25 and 3.5 bay with a dreadful ~200W PSU. $43 for a 65W PSU is a good deal.

What HDDs were you using?
My primary HDD is a Toshiba 500GB 2.5" and my storage HDD is a WD 1.5TB EARS, they are set to go off after 3-min in WinXP.

So unless you're building a server, the lack of the IGP at 8-10W makes this chip very limited. But of course servers are exactly the intended market. I know you can overclock the IGP, perhaps also underclock, maybe to the point of turning it off or at least to 1W. For me the IGP made Clarkdale, meet...

Methinks the chipset itself isn't the culprit but rather the implementation? I agree. H57 goes into higher end MBs which begets more VRM's which consume more power. Also, the default settings could very well be different. None the less a good find because it reminds us to dot the i's and cross the ...

The main plug is only 20 instead of 24 pins (I think). So the mobo will not even post. Not posting is almost always because you don't have the 4-pin CPU power plug connected. 20/24 pins is relatively unimportant. If your existing PSU does not have a 4-pin CPU connector then it's incredibly old and ...

I believe that the 530 does not have turbo. Is that correct? Correct. But TB is only one multiplier step. So if stock was 22X, then TB would be 23X. To me that was marketing hype with almost no benefit. With a good MB I should be able to get the 530 to the equivalent of ~35X by upping the FSB. I wo...

I have an i3 530 w/ a stock HSF. I've never heard it. It's in a mATX case on the bottom shelf of a coffee table. Since the whole rig idles at 34W, not much reason for any of the 3 fans to spin fast.

Curious, what feature does a i5 66x offer to warrant paying double over the 530?

For the life of me I can't figure out on what basis SPRC gave the Pico a better rating. Well the PicoPSU with the right brick is more efficient than the Winmate, precisely because of the 12V regulation you mention. It's questionable if modern MB's need that regulation since they have many stage VRM...

I'll bet that Zalman took at least 10W just to run itself. Quick test to find out (green to black). But 15W is impressive.
