What size power supply for my setup?

Pages: (1/3) > >>

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 :o

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


M.Lanza:

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?
