LC Power 1320mi 75W psu enough for Celeron G530 and a H61 mobo?

post #1 of 7
Thread Starter 
Hey gang, my Asrock ION330 (see sig) went to Kingdom Come, trying to decide to build a low cosumtion, everyday pc for light apps (browosing, downloading, music playback, dvd and avi playback)...

So, i am going for the G530 cpu, an H61 mini ITX mobo (haven't decided yet, probably Asus or Gigabyte), a stick of 4Gb DDR3 Ram and the LC Power 1320mi.

(already have a OCZ Vertex 2 60Gb ssd and the slim dvd-rw of the ION 330)

I wonder if the 75W psu of the LC is enough for a system like this...

Thanks in advance guys...

I honestly don't think 75w is enough, I heard the single core sandy bridge celerons are low power giants.

I was reading this review: http://forums.overclockersclub.com/index.php?showtopic=190691 and checked the power consumption...

Funny thing is that the guy used a 400W psu which normally should be not very efficient at this kind of low wattage so some of the watts he measured are actually because of the psu...

You will be perfectly fine with 1 hard drive and OSD.

Thanks for the reply.

I've seen couple other guys with this kind of setup (same case/psu) with G530 and G620 cpus running with no probs...

I'll undervolt the G530 anyway so i guess i'll be fine.

Thanks again. wink.gif

Soooo, just in case somebody thinks to go the same route...

The system is up and running since last week.

LC POWER LC-1320mi (75W psu)
Gigabyte GA-H61N-USB3
Celeron G530
Kingston ValueRAM 4GB (2 x 2GB) DDR3 1333MHz
Slim optical drive
Sweex USB speakers
USB keyboard/mouse

With the default settings it idles at 22-23W, full load (Prime) peaked at 54W.

With a little fine tuning, it's 101% stable with -0.185V offset, that means that under the most hardcore load the absolute max peak Vcore is 1.056V, so full load (Prime) wattage droped down to 45W.

The psu seems just fine for this setup, browsing, office work etc consume less than 30W total.

Don't even thinkg to add a vga with this setup, it won't even start which makes sense since this specific psu seems to provide less than 6A (if i am not mistaken) on the +12V (tried it with my HD5450).

Anybody that has as a #1 priority the minimum consumption under load (and not caring about the performance) can also underclock it down to 1.6Ghz, max Vcore needed at this frequency is waaaay less than 1V (sorry i can't recall the exact value), the wattage can be reduced down to 32W under full load...
