Anyone do SLI or Crossfire with a Seasonic 500w?

[coolpurplefan]

Since I read on Anandtech that the next generation of video cards is going to use 130 to 300 watts, I was wondering if anyone here is using SLI with a Seasonic 500 watt. I have one but currently I only have a Geforce 6600 (non-GT). I`m waiting for benchmarks on UT2007 before I upgrade. I just want to know out of sheer curiosity if anyone is able to use two 100 watt video cards at the same time with a Seasonic 500 watt.

BTW, I have to say I thought it would be more silent than an Enermax. I find that it`s not that much more silent. Even the Zalman 7000 is not much more quieter than the Gigabyte Neon Cooler 8 I used to have. (I move and got different hardware. But, I do like the Samsung Spinpoint 250 GB PATA drive and BenQ DW1655. They`re silent and perform well.)

It depends on what your SLI...but Seasonics have very good effeciency so should work with most set-ups

500w for crossfire is a close call. SLI fares a tiny bit better. I say go with the 600w version.

Reason I say so is your upgrade path may be hindered by a lack of umph.

For a while, I ran both a X1900XTX and a X800XL w/ my Seasonic S12 500. I was experimenting w/ running multiple monitors and I had no problems.

Problem is a 1900XTX uses MUCH more power than an X800XL AND unless you were gaming you weren't even pushing the X800XL to full load which again will use less power.
I would use more than a 500 watt Quality PSU for Crossfired XTX's...

yep

ran 7800GT SLI with that very PSU and overclocked A64 with a fully stocked up motherboard. no issues what so ever

X1900XT CF might be a challenge mind, but i would reckon it could easily power 7900GT's in SLI and very probably 7900GTX's
