IMHO picoPSU has nothing to do with AC, it must be ACDC brick problem.... I meant the brick of the picoPSU, of course. take some car 12V bulb (20W,50W etc), connect it to your ACDC adapter and measure with kill-a-watt (to be more accurate, measure current and voltage on a bulb)...... Thanks, but I ...

What are you using to measure power? I know many of those things have problems measuring well at low loads, especially when the power drawn is highly reactive. Many power supplies, including many power bricks, have extremely poor power factors at no/low loads, which power readers don't read properl...

b3nbranch,

When you connect the 110W brick to the Kill-A-Watt device, without connecting the brick even to the picoPSU, how much wattage does it take ?

Btw, what is the voltage in your outlet, 120V or 230V ?, I'm starting to think that maybe this brick is less efficient with 230V outlets...

Can people with the 120W or 80W bricks, who bought them from Mini-Box, please report the power consumption of the brick ?

Heh.....you can run a PICO without a brick. You simply hook the PICO to a 12V car battery, attach a solar panel to your roof to charge the battery......works perfectly. I'm doing it with my PICO-powered P4-2.4.
Good idea, but I'm living in an apartment.

Got the picoPSU-120 today, expecting big changes, but received none. I bought it with the 110W ACDC brick. My computer consists of: - Athlon XP2400 @ 933mhz (1.15v) - 7VM400M-RZ Gigabyte motherboard. - Gigabit lan card. - 1 stick of 512mb memory. - 1 40GB desktop hard drive. - 2 fans with zalman fan...

frank2003, The explanation regarding 1080p is simple. Some 1080p material is encoded using the old MPEG2 algorithm. In order to decode it you don't need a powerfull CPU. AVC (which is also called MPEG4, and also called H.264) is a much more powerful encoder thatn MPEG2, which gives much better quali...

Thanks Felger.

ist.martin,
You are wasting money with the flash drive. For the same amount of money, you can get 10X the storage with a 2.5" laptop drive. Differences in power consumption will be negligible.

A few years back I cut some bridges on a Duron 1400 and ended upp with a Vcore that was a bit too low. I then upped the Vcore a bit with a pin mod, using U-shaped pieces of copper wire that I dropped into the CPU socket before installing the CPU. The AMD data sheets should tell you all you need to ...

No idea but it is more efficient than a Seasonic S12-380W power supply. If I recall correctly, power consumption went down ~10% when I switched over to the brick. Well, Kentc uses a pretty much identical setup to yours, apart from the PSU, and gets 22W at idle, so I think your PSU is not THAT effic...

Well, my experience definitely isn't the be all end all anyway. Possibly clearing CMOS, and then putting your new voltages back could help. Getting the voltages back to normal means to connect the cut bridge, not something easy, and in any case, I have no wish to use the mobo/cpu at the original se...

Ok, but the PSU that Amourek used on 690G was not one of them used on biostar 7025
This is incorrect.

Amourek used, for both the 7025 and 690G, the exact same PSU - Forton Sparkle 400W.

I couldn't find the full datasheet so I assumed the Seagate takes around 10W idle, in comparison to around 1W idle for the laptop. Anyway, even if the difference is 6W, it still means the Biostar TF7025-M2 should take 15.5W at idle (with voltage ~0.9v), which is simply amazing (especially taking int...

My own experience has taught me that if you get BSODs when installing/ reinstalling then it is almost always memory problems. I mean your RAM is set too fast in the BIOS. Make the timings slower and giving it more voltage will probably help. 1. I did not change anything regarding the memory, all I ...
