Thread Starter 
what PSU wattage do i need to power an A 3500, an itx mobo and 1 HDD?
i was thinking of using this , does anyone know if this will be enough and also can someone link me to a place where i can buy a power brick for it in AUS?

thanks in advance

EDIT: it needs to be able to fit in an Xbox 360 case, so size is a bit of an issue

does it also estimate extra watts from the CPU from overclocking?

EDIT: just used the calculator, suggest 189 W but minimum is 139 W; including a overclock to 3 Gigahertz and a 1.4 voltage. if i was using this as a casual browsing and emulating computer 150 w PSU should be fine? as it will not be using 100% load often.

350-450w is probably good but finding efficient psu while having a quiet fan is slim pickings

look for SeaSonic S12II 380W or antec earth 430w

scratch this as size is factor in xbox 360 casing

150W is kind of cutting it close, maybe 180W-250w if you're really trying to have a low power consumption plus for your build. smile.gif

What you need is a PICO PSU and a power brick... something in the 150-180W area would do fine.

I just bought the picoPSU 160 watt xt off eBay, but it didn't include a power pack, can anyone link me to an Australian store selling them for a decent price?

Assuming that you have a PSU with a 12v input, at those power levels your choices will be limited. You would be looking at something probably like this: , which I wouldn't be able to guarantee the rail stability of for use in a computer. However if you have a multi-input PSU, you could use something like this: , In which case you would need to modify the supply to suit your needs since the built-on plug probably wouldn't be very useful to you.

If it's not too late you could consider something like this: or . But once again without any solid reviews it's hard to give an idea of the power quality.

EDIT: There are also these: Which do appear to ship overseas but the calculator won't work and it's a fair bet that international shipping is extortionate.

Only if it outputs 12V, and as you say, if it's rated for enough amps (160W would be like 13A at 12V, if you actually need up to around 160W which you probably don't).

Most don't output 12V.
