PicoPSU Question.

Hi guys. Hopefully some of you are knowledgable on these things!

Basically I want to try an run my atx pc off one. The specs arn't special (Gigabyte GA965PAS3 / 4gb / E2160 / 8600gt / 5400rpm 2.5" HD) and so I have a power monitor showing my system using aroun 90-100w on idle and 130w at load.

Because of this, o people think I would be ok running off a 150w Pico or would it be a little safer to look at 180/200w??

Thanks

It will not work.
The reason is the 8600gt with a max power at load of 67W
It will have worked with an integrated video card.
A good 200W ATX power supply will work.

Well, he said "good 200W ATX power supply". There is PW-200 series made by the same company as picoPSU (mini-box). But electrodacus doesn't want to recommend it. You can search the forums for various experiences people have had with it.

Another alternative is to use a separate power source for the CPU, provided via the P4 connector on your motherboard, and use picoPSU for the main power (20 or 24--pin ATX connector on your motherboard).

You can use two separate external power bricks for the two sources, or one big power brick such as Dell DA-2 but split the power into two strands. Search for DA-2 on the forums for more info.

A 200+W dc-dc board like the PV-200-V/M + a Dell DA-2 brick should run that system just fine.

I ran this system of a PV-200-V and a Dell DA-2 brick with no problems.

AuraAllan, Thanks for joining us. I have been meaning to ask a couple of questions about your system.

What is the type of the junction box that you used to splice the wires from your mating connector to the PW-200's leads? And, do I see some kind of a red connector/switch for the trigger/remote line of DA-2?

I am also curious about the green/red braided lead that seems to connect to the black connector at the back (2.5mm jack again)?

That was a real sexy system you built there! Pity that you dismantled it.

Uday

Sorry for hi-jacking this thread a bit.

It's a terminal strip

No. It's a (what is the English word for this? I don't think it's called a terminal strip) used for shielding of a spare wire.

The one hanging out the back in this picture? It's the power button.

Thanks. I've been thinking about doing a new build in the case. Also thinking about redoing the case again but i'm not sure.
Will start a thread about it if I decide to do another build in the NSK.

If you have anymore questions for this build (or suggestions for a new build) please use my NSK1300 thread.

It's called a BP Connector here in Australia. I don't recall ever using them as a sparky in the UK so maybe he can just use an insulated crimp connector instead.

Thanks very much AuraAllan. I was planning to put a switch for the 'remote' lead of DA-2. So I was curious if you were doing it too. But it looks like you have the remote lead permanently shorted to GND. The pin 1 line, I will probably leave disconnected in my connector.
