just ordered the following and want to check I dont need a new PSU I'm sure its ok but want to check

PSU is a seasonic 600w

new bits

fx8350 , GA-990FXA-UD3 and currently a 5850 but will get a 7950 or whatever new gen case comes out.

cheers

Should be fine mate, infact should be more than enough.

badcompany · 29 Jan 2013 at 08:40

should have added 3/4 harddrives

No single GPU setup will trouble a seasonic PSU

If its the G series PSU then the 600W should be enough to x-fire 2 7950's

I run an 8350 at 4.6GHz, HD6950 2Gb, 3 HDD, 8Gb ram at 2.0GHz, Asus mobo.
Prime on eight cores large FFT = 360w, prime + heaven 2.5 benchmark= 480w

Power draw taken at wall socket for the full system, the above are the maximum readings I can make happen and are not exceeded when benching AIDA at 5Ghz although I cannot prime on eight threads at this overclock. Normal idle, browsing etc. 130w.

I use a seasonic x650 gold.

People tend to overspec PSU's. That one is more than powerful enough.

If taken from the wall times the reading by 0.8. As most PSU's are 80% efficient so if a system pulls 100w from the wall, then components are only pulling 80w from the PSU.

The 80% is the conversion rate from AC to DC.

AC at the wall. DC PSU side.

Running a high wattage PSU on a lowish consuming system is bad for the electricity bill too, as they do not reach top efficiency.

My system pulls 410w at the wall, so 328w from PSU, so my 800w PSU is likely to only be at about 60% efficiency...

Truly very useful, I should have thought of that, thanks.
