So isnt it kind of pointless to buy this DC-DC if it will be used with a psu brick that's less than 85% efficient? Assuming the DC-DC is 93% efficient and you use a 85% efficient brick, then your overall efficiency is only roughly 79%. Even under low loads of 40W-ish, you would probably get roughly...

By overclocking you need more energy for unit of calculation so is not green.
For example at 100% load my Q8400S CPU will use 24W at 2Ghz compared with 86W at 3Ghz
So 12W/Ghz underclocked vs 28W/Ghz overclocked this is a big difference.

Has anyone tested whether the improvements of going DC-DC are actually that significant as opposed to maybe just getting an 80plus psu like an Antec EA380? Even if you were to pair it up with a 90% efficient AC-DC adapter, the combined efficiency of the DC-DC and the AC adapter will be only around ...

I need only the 130W PSU and ATX cable.

Shipping to Russia will be 21.95$ For PSU + cables

Maybe he was referring to electrodacus who has posted a system idle of 31W with a heavily undervolted quadcore (the cpu was using 24W of that). The CPU was using 4W out of total of 31W at idle and the system will use 35W if not undervolted with CPU using 8W at idle. So if the Atom board is using 26...

I also sell 130W and 120W fanless PSU they are not as small as the PicoPSU but they have a 12V DC-DC converter so the 12V will be much more stable also there are about 6x higher value capacitors compare to PicoPSU but if space is a limitation then PicoPSU is better. The price you are offering them ...

WOW Great setup 28W CPU and 12W northbridge this is actually a notebook. How expensive was the MB ? It will be difficult to answer to your question because this is a mobile setup and I have no idea if your board will use 12V for CPU or 5V. I do not see any P4 connector on the MB they can use one of ...

You can check the PSU I have for sale you can also read the review here on SPCR.

Gigabyte MA790XTA-UD4, 4Gb G.Skill 1.35v DDR3, Intel SSD, AMD 605e, Powercolor 5750 If I had to do it again I would get a faster processor and a slower/cooler video card. Maybe the 5750 Eco/Green edition or a GT220 or 240 fanless which I think use less power, and a 65w Intel Q9550s. Even if I had t...

Asus P5KPL-AM iG31 Any reason you are not using the integrated graphics? That should be some easy savings right there. i have 2 screens running from this machine 1 is a 32" tv and the other is a 15" photo frame. also i need to have direct rendering enabled to run moovida (htpc software) i have swap...

2.The AC adapter is heavy 820g plus the AC cord 160g total 980g and if I add the shipping box ATX cable adapter cable and PSU the total will be close to 1.4kg an this is bad because the shipping cost is higher. Should have skipped the power cord that with american plug is worthless for me (actuallt...

I was under the impression that the extra pin is only used to identify the power supply to the laptop. It connects to a Maxim 1-wire id chip. Yes you are right but do you know the ID even so it dose not worth the trouble. I have one 90W DELL bricks 20V 4.5A and it outputs 20V but no current and you...

Certainly true with Atom, the chipset consumes more than Atom. That's about to change with Clarkdale, only one generation behind. Early number are very encouraging. You mention MB power, have you measured and/or seen test. MB power tends to be lumped into some big power envelope and not broken out....

Anyone attempt to modify a notebook power supply for use with this DC-DC, such as the Dell 90W adapters which can go for <$20? The newer Dell AC-DC bricks appear to be very efficient, but there is also an extra "data" pin which I am not sure if it can be ignored. There isnt exactly that much data a...

Yes more than enough.

Hi MtnHermit welcome to SPCR. The best computational power vs power consumption (for the CPU) is at about 1.8Ghz but 2Ghz is much better number :) The problem is not the CPU it only uses less than 4W at idle the problem is the motherboard and chipsets. The chipsets are always two or more generation ...

With your setup (45W CPU) the 130W ATX PSU and 150W brick will work just fine see my products on eBay and the review on SPCR

Hi,
I'm from Canada and I can provide you with a 150W AC adapter and 130W fanless ATX PSU see in my signature you can find may products on eBay and the review on SPCR

Would this work for video cards? I just bought a gtx260 with 2 pin power connectors. :) are you serious ?!! gtx260 has a TDP of 182W you will need two of my power supply only for the video card and probably at least another one for the rest of the system. It will work with 3 PSU but it will be to c...

Just until the end of the year you can get 10% off from the regular price that is anyway 3x less than MSRP. see Link

Steve_Y - Thanks for all the comparison interesting to know. About the Athlon XP system I have no idea why it will not work this is first time I hear the system will not start and some even used with core i5 systems. swivelguy2 - It will be preferable to have an external brick so big part of the hea...

Hi Steve_Y, Can you provide the spec of your spare PC that dose not work with the Winmate PSU. I can only think on two possibilities one that you did not connect the P4 cable that is supplying the CPU and the second that the 5V line at start up is using more than 7 to 8A and the overcurrent protecti...

If you do not need 250W I can sell you a fanless 130W PSU see details in my signature.
I assumed is for the system in your signature and it will work (maybe you can give more details if you are interested).

I purchased the DC-DC converter with a Gateway brick from Electrodacus and just tried it out with a system I'm setting up. The system is pretty basic: MSI G45M Digital, E3200, 4GB RAM, Intel X25-M, SMC PCI-N and a DVD burner. For a PSU, I was using an old Seasonic 300W Super Toronado which is not v...

Am I stupid or can't one get one of these outside Canada, let alone Europe ? Ebay page has shipping in Canada only. I sell world wide if you look at the end of eBay listing you will see the shipping for some country. Most of my sales are in Europe the price is almost the same for all European count...

nirvanaguy19 And Intel D945GCLF2 has just 16W max wattage. Is more like double only the North bridge + south bridge + Atom 330 max TDP is 33.5W so I will not expect less than 28W from this board at idle with nothing connected but the board and RAM. See Link The 90W and 120W PicoPSU have the same sp...

For low power consumption I will not recommend core i7 or i5 the new architecture is not as power efficient as the old one. I will recommend and older Q8xxx or Q9xxx and a low power LGA 775 board The power consumption vs computational power is much better for Qxxxx an for an off-grid is very importa...

Mike, that's a good idea. I could take the existing AC-DC adapter, cut off the end and replace with a male barrel connector. I would then cut off the end of the Antec power cable (the connector that attached to the Antec DC-DC converter) and replace it with a male 4-pin connector from the Winmate. ...

I can not believe they can use a 58W TDP with passive cooling. It will probably need very good air circulation and then is no benefit (not silent).
I think you can really call a video card passive if is less than 20W TDP.

Thanks for the Link really useful to see power consumption at min and max brightness. The 30" are taking much more power at min that I will have expected.
