I have this power supply: Antec True Power Trio 650w. And I was wondering if I could power two of thesecards in SLI.

It doesn't have enough PCI-E connectors.

Is that not enough? Why the hell does the thing say nVidia SLI certified then?

you need 4 pci-e 6-pin power connectors. 2 for each card.

edit: it is nvidia SLI certified, just not for every nvidia card.

Damn... I am getting an Antec Quatro 1000W with my case, but I wanted to sell it to get my money back for my case.

The 9800gtx has two pci-e connectors on each card. It's certified for cards that only have one power connector.

I wouldn't trust that psu anyway, read.

Quote:
This time around, the PSU failed test 6 after having only run for 5 minutes. And the PSU didn't just shut down like the Thermaltake 750W did. There was a pop and a flash and the PSU was dead. I opened up the unit, probed around and found that the fuse had blown. Normally, I would have just replaced the fuse, but Antec had soldered the fuse to the fuse holder. I could have desoldered everything, but I decided that I'd give an RMA a try.

After I received the replacement PSU, I went through all of the testing for a second time. Once again, only 5 minutes into test 6, there was a loud pop, a flash of white light and the second PSU was dead.

Now in all fairness, the Antec Trio did maintain 647.5W during test 5. Test 6 is only 7.5W more output power, but the load is shifted from the 3.3V and 5V to the 12V. Perhaps the 12V rails on this thing are over rated?

Stupid question, but let's say I keep my Antec TruePower Quatro 1000w and I use it without SLI (I won't be getting my 2nd XFX GeForce 9800GTX for a while), will it always be using 1000 watts of energy when on?
