Since I need a new PSU along with a GX460, I'm on the hunt for the right PSU. I don't want to spend stupid money on one, but I'd like one with a minimum of 3 years warranty (the Corsair is 5yrs for example): Curent spec: Dell (foxconn I think) mobo Intel Q8200 on std cooling (though I'll likely add a Coolermaster V8 at xmas) 4 GB DDR2, 800mhz RAM Currently using a HIC 1GB HD 4670 GTX 460 (to be added with psu) Future plans: 2/3 SLI motherboard Most likely a i5 750 (though may go i7 route) 6-8 GB RAM 2/3 GTX460's OS: Windows 7 Pro 64bit / Linux 64bit Drive wise, I have one Crucial 256GB SSD, and one Hitachi 1GB drive. I'll also be adding another SSD later on for Linux solely to use. All SATA. Plus 2x SATA optical drives. I was looking at around 850w, (I was briefly advised in another post 750w wasn't enough). I like this: http://www.ebuyer.com/product/152604 Also these: http://www.ebuyer.com/product/124736 http://www.ebuyer.com/product/176413 Please note I may not purchase from ebuyer, its just easier looking on one site til I've made my mind up, then I'll hunt out the best price. So I've three questions really: 1. I've set around £120 max for a PSU. Are the above good choices? 2. I'd like a PSU that will last me the next 4-5 years - Is 850w enough to power 2 GTX460's? 3. How much power does 1 GTX460 really need? The next card I get I'll be adding another later on when gaming requires it - I'm looking long term here, I don't plan on adding a 2nd one until at least I've changed my CPU/motherboard which won't be for another 12 months. I don't want to be purchasing yet another PSU though, so it needs to handle my future plans, no matter how they turn out - I'd rather use that money towards a mobo and cpu next time! So what do all you experts think then?
