My Enermax 1250W not enough? need help!

post #1 of 32
Thread Starter 
I am in this little complicated situation, was putting my first watercooling rig together (took it appart and add some wc parts) and at first I could turn on the pc with my tri-sli setup intact, so then I ended up putting/connecting all the other remaining parts together and when I turned on the pc again my rig only read 2 cards and not three, and my sli configuration got all messed up (see sig for my setup). The main question I have is, since I converted my aircooled rig into a watercooled rig was the juice not enough??? below is the specs on everything connected to the psu. Ran the rig again with 2 cards and everything ran 100%


intel i7 950 @ 4.13ghz @ 1.35v
Asus Rampage III Formula
12GB Corsair dominator DDR3 1600mhz
(3) GTX480s at stock
(1) intel X25-M 80GB SSD
(3) optical drives
NZXT fan controller/temp monitor
(9) Noise Blocker 1700rpm PK3 140mm fans
(1) Noise Blocker 1400rpm 120mm fan
EK-DCP 4.0 pump
(6) 8" inch cathode lights

with all this make the 1250w psu not run 100% causing 1 video card to not recieve power? (troubleshooted that 1 card was indeed not running on power since I touched the card (cold) while playing a game and the other 2 were super hot)

Should I just get a 1500watt psu??? or trouble shoot something else??

right now the rig is running fine with 2 cards in sli (already checked all three cards one by one and they all work, checked the pci-e sockets with different card configurations, all work and check all the 8 and 6 pin power connectors and they all work too, its only when I add the other card system wont see 3rd card and that card is cold as ice.

***note: ran rig in another case with everything except I only had 4 fans running, 1 optical drive, it was aircooled and had an additional harddrive, everything ran with no problems***

Your PSU should still be enough, did you try reinstalling the drivers? Or perhaps the 3rd PCI-E lane got disabled accidentally by those lane switches? My R3E has it so your Formula might too, go check.

or get a good 1200w...

you shouldn't be at the of that PSU limit yet.. something is out of wack or your psu is a POS...

I believe the Antec Quattro is the most recommended 1200w psu

well I do know that all three gpu lanes work coz I tried them out one at a time and in sli configurations ex: 1st/3rd 1st/2nd 2nd/3rd all work, its just when I try running in tri-sli with putting all the cards in different configurations it just shows that 2/3 cards are powered on and 1 is turned off, no matter where I place each card in a different slot with a different configuration there will always be one card that is off and if my rig has a lane switch, how could I turn it back on, do I go into bios or something???

Are you high?

Enermax makes some of the best high wattage power supplies.

You obviously don't know much about PSU's now do you.

Try plugging a 4-pin molex connector (next to the NB).

If that doesn't work, increase PCI-E frequency to 105MHz in the BIOS.

You tried making sure all your switches near the ram slots were in the ON position?

The lane switches are actual switches on the motherboard if you have them. Though I just looked at a pic of your mobo, doesn't look like you have it on yours. Sorry man, don't know what the problem is. >.<
