What size power supply for my setup?

[ivwshane]

I currently have a 300w ps and it is only able to power:
1 hard drive
amd athlon 3200+
2 u360
1 electric ice trackball (no leds)
1 usb wireless device
2 nova matrix marquee lights
2 triple red leds

anything more and windows won't even boot

Besides the above I need to add:
3 led wiz's (~30 led connections in use x2)
an additional hard drive

and enough over head to add additional lights or something

A 450W + power supply should suit your needs.

How positive are you? The power supply is one of those things I don't want to have to buy again;)

If you want a really good power supply check out some of the pc power and cooling ones.  This one in particular is a 500 watt that should be plenty and it's on sale for 20 dollars off.  Remember that the watts aren't even thing in getting a good power supply:

I wonder if this is a better ps to get since it supports a higher amperage on the 3.3v and 5v rails.

Because I don't have a highend cpu or gpu I think the dual rails should be fine and I think having a higher max wattage on the combined 3.3v, 5v (152w vs 130 on the pc power and cooling) would be a bigger advantage.


What do you guys think?

This is what I have in my cab...

I would buy quality over wattage but that’s me.

Both of the ones you listed are 500 watts.  I've never heard of fsp, but that doesn't mean its not a good power supply.  As vistor q mentioned, a good power supply is really important, regardless if your running a how powered cpu etc.  This is the power supply I have in my main setup and it's been great.  Lots of posetive reviews too.  There is a 700 watt for 5 dollars more as well, althought I think that's overkill:

Thanks for the info guys. I decided that for the same price (after rebate) as the one I was going to originally get I could get this one instead:

FSP usually makes pretty good power supplies but does not match the quality of corsair, seasonic, pcp&c.

Very Nice! Good Choice!

The wattages on power supplies are ususally some fantasy figure made up by someone that wouldnt even know their amps from their arse.

You should be fine on that minimally specced out PC with a real 300 watt power supply - Hell, I have more crap on my desktop PC that only has a 225w psu in it, but it can actually deliver it.

I would guess that your power supply came with a case, and is worth exactly what you paid for it - nothing. Any actual power supply should be able to run a machine like that. If you had a 3d card, and multiple harddrives then you start to need to think about going 400+ watts, other then that its a small draw.

Above post is 100% correct. I would say stick to a known quality brand name and you will be ok.
