PSU Recommendations
« on: December 14, 2007, 10:26:11 AM »
I purchased 2 XFX 8800 GT's last night. I read that it is required that you have at least a 400W PSU, however after talking to one of my friends he said that he personally wouldn't attempt to do SLI with under a 600W PSU, but he also said something to the effect of PSU's that are running closer to their full output run with greater efficiency as opposed to when they are not being used as much.

Do you guys think that my Kingwin 520W PSU will be able to take the load of those 2 cards running in SLI, as well as the 3 SATA drives I have? Or would I be better off making the additional investment in a more powerful PSU, such as an 800W Kingwin PSU?

I think the answer is "3".  Or, maybe "3" is the age of the person who typed those hyperlinks.  Or, perhaps "3" is the number of minutes I won't get back after contemplating your question and deciding that I have no clue.

In any case, "3" fits in there somewhere.

I'm sure someone here will be able to answer this.

I personally wouldn't run this on 400W PS. the PS is the component that is given less attention than it deserves. Cheap PS can actually damage components. I would go with somehting like this, or better: http://www.ncixus.com/products/18184/OCZ600GXSSLI/OCZ%20Technology/

I tried Newegg's wattage calculator and with the specs for my system it said I'd need at least 750W. So it'd probably be good to go with an 800W PS if not something a little more powerful. I really like Kingwin PS's though, so I'd like to stay with them unless someone knows a brand that is significantly better. I was surprised though to see how much of a price difference there is between an 800W PS and a 900W PS, 100$ price difference, while there is only a 20$ price difference between a 900W PS and a 1000W PS.  :?

I wouldn't try it with any less than an 800w supply. I recently rebuilt my computer at home and went SLI with two disk drives and two optical drives with an 800w supply. I just didn't want to take chances of overloading the PSU.

I ended up going with a 620W Corsair PS. Read some great reviews about it, hopefully it will work as well as people say it does.
