time to change PSU?

[subzero813]

my system will have the following:

dfi lanparty nf4 sli-dr mobo
amd opteron s939 overclocked to at least 2.8ghz (hopefully staying under 1.5v)
gf 7800gtx (only one)
sb audigy2 zs gamer
1 dvd drive, 1 cd drive, 2 hard drives, and several fans.

is my old Antec 480W power supply still enough for this? or should i upgrade to a 550W?

i also think the Antec has a 20 pin motherboard connector, not 24 pin...so do i have to upgrade regardless? and can anyone recommend a good place to get a 550w psu (i will eventually move to SLI and overclocked athlonX2).

your 480 should be fine.....if your going to keep that system you might go ahead a get a new PSU when you switch to using the SLI....just my opinion!

your "old antec 480W"? minus the word "old", i'd say your PSU is set for just about anything...NO i wouldn't feel you need to go over 500W.

after all, your current PSU is made by a very reputable company that stands behind their products.

Yeah, I put my old 6800U in my bro's computer, which has a Antec True 480...the GTX consumes LESS power than the 6800 series, and that 480 works fine. Don't worry, it'll handle it.

Why SLI MOBO if your not SLI'ing up grading for the future

JW I'm not really sold on the SLI thing
