Re: Dedicated video card power supply unit?

sorry id rather spend £60 on a new PSU than that, means more stuff in my case.

maybe just me being picky!

Re: Dedicated video card power supply unit?

yeah--i wouldn't even consider one for a brand new build. there have been a lot of folks on the boards lately that are upgrading (trying to upgrade) their factory boxes with underpowered psu's with high-end gpu's.

i'm considering doing a mini-build--migrating my current pc3200 and x800xt (agp) into a C2D mobo/processor system, and then later buying a better mobo and leaving agp and ddr behind for good in favor of pci-e and ddr2. grabbing one of these might open some options with the $100 I'd save on an acceptably quiet/powerful psu.

Plus (depending on the build quality) it will migrate just fine for the foreseeable future.

I would not recommend that set up. It would not be the best arrangement for power management and stability. Do yourself a favor and buy the right size PSU to run your system with your graphics card and all the peripherials especially if they are powered through your USB ports.

Re: Dedicated video card power supply unit?

it looks great for people like me who are just begginer builders.

As far as stability goes, I'm almost certain I would have woken up during physics 101 if the professor had suggested that the laws of the universe would allow a gpu to be able to discriminate between electrons flowing from the "outboard" (gpu) psu from electrons flowing from the "inboard" (main) one.

There are some potential heat issues I hadn't considered (yet), but offloading a gpu's power onto a dedicated box frees up those watts to push another 120mm cooling fan (if three wasn't enough :) ).

It isn't a perfect solution--for a total rebuild a modular >550W psu with one giant, quiet cooling fan would be the way I'd go. Outboarding the gpu does, however, offer a straightforward (and relatively inexpensive) way to add an x1950xt or a 7950gt to a factory box, or to upgrade an existing pc in smaller increments than a total redux.

a Hiper 580w psu is supposed to be enough to drive crossfire ati cards and the usual assortment of stuff in your pc for only £60
