Did some research online regarding 3 way sli with GTX480s on a basic system and the card configuration peaks near 1000watts if not abit higher with only the cards, so if that's the case adding all the other stuff to the psu (cpu,mb,drives,pump,etc) I don't really think 250watts would be suffecient enough.
Another thing when I had my rig running on Aircooling, in another case, I didnt have that many things connected to it and my 3way worked 100% with no hiccup, and when I moved to watercooling and only added the basics (cpu,pump,ssd,and 3 cards) the rig showed 3 cards in tri-sli and then when I connected everything else (10fans,3opticaldrives,fancontroller/temp monitor, and 6 cathode lights, and also OC the cpu to 4.1ghz) that's when everything started acting funny.
And just to help troubleshoot this problem, again, see below
1) All three cards still work (tried them 1 by 1 and all ran fine)
2) All PCI-E gpu slot still work, checked bios and all three have a reading (plus ran 1 card in a different slot and card is powered and showing at the control panel)
3) Checked PSU with all its cables (with just 2/3) works, its just when I put 3 cards 1 card doesnt recieve power and *************sometimes 2/3 cards are not recieving power (new update just checked last night)*****
and only 1 shows on the control panel
Hope this helps further guys,
Thanks in advance!Edited by GeeK671 - 12/23/10 at 3:02pm
