My System Specs

Default

for not starting another thread I will post here :
PSU XFX core edition 650, 650W 80 Plus bronze (2x6 pin and 2x6+2 pin)
will it run this configuration ?

AMD Phenom II X4 955 or X6 1035T.
no ovc but 100% load from SMP folding or on 4 cores on the x6
GTX 460 1GB, one GTS 250, one 9800GTX+
1 SSD , 1 hdd@7200RPM 2 green drives @5400RPM, blu ray unit (occasional use)
5x120mm led fans plus 1x250mm fan

if it would run all this, do you think would be any room left for a video card that does not require an additional power connector, style GT240 or 430GT?

200-250 for pc

130 for 460

130 for 250

130 for 9800gtx+

its gonna be close. those are 12v rail wattage use. plus minus.

I wouldn't do it. Would say it will run the system with 2 of the graphics cards fine, but I wouldn't throw the third one in it. It may work fine with all 3, but your pushing it pretty hard (that's a quality PSU, just not powerful enough for 3 GPU IMO min would be a quality 850w to run that).

then you will shave off 30 or so watts. a little easier on the psu. if the cpu loads.

XFX Core Edition 650W & 750W Pro Review

Assuming hardware.fr's Furmark figures are your F@H figures, this won't do:

151W (GTX460) + 162W (GTS 250) + 169W (9800GTX+) ~= 482W
Then add your Athlon II CPU at 70W, and chipset+ HDD at 30W... ~= 582W

Your PSU can do 636W on the +12V rail so you wouldn't even have the headroom to run a low-end 3D GPU of any kind without being on the verge of overcurrent shutdown. The PSU is decently efficient but it will still heat up - don't expect it to last long...

You may be a little better off if you undervolt the CPU and make sure all the GPUs are at stock clocks, but I'd personally jump to something with 200 more watts on the +12V.

Furmark stresses a GPU way more than Folding ever will.

My daily driver with a Q9450@3.4, a 9800GTX and a GTS 250 on a HX520 PSU draws around 330w's at the UPS with all three OC'd and Folding.

A 9800GTX/9800GTX+/GTS250 class card draws 100w at most when Folding and the GTX 460 should draw about the same or less.

A quality 650w PSU should be able to handle those three videocards easily especially if there not overclocked and should be able to take the GT240/GT430 on top of that though it might run a little warm...

Yes, absolutely

Quote:
For maximum efficiency (and thus, less waste heat and such) it's best to run the PSU between 50 and 80%
No, efficiency is so variable that it is hard to tell which will be less efficient where... If you want maximum efficiency get a gold or platinum power supply. Many gold efficiency power supplies can outperform bronze efficiency power supplies even with lower wattage ratings

95% of power supplies fall under this curve, it doesn't matter what 80+ PSU you get, you're going to not be at the unit's maximum efficiency unless you're loading about 50 - 80%. it's obviously variable for every PSU, but it's not that variable, sorry ;)
