Hello, I would like some advice before buying a new PSU for my new build. In fact I'd like to know which 1000W (or so for a future dual 560 gtx ti) PSU looks the best (price/performance/quality. Also, I'll be using the Antec twelve hundred V3, which is a really big case, so just make sure I'll be able to reach all my components.

Thanks a lot for all your advice :)

First, you should list your entire build to evaluate your PSU requirements. A dual GTX 560 ti should run fine with 850 W PSU (actuallly about 800 W should do). With PSUs go for the gold: not only in efficiency but also in reliability. Corsair, Antec, PC Power and Cooling (although they have fallen off the reliability rep that they once had when the sourced with Seasonic), Seasonic, and even Cougar and Lepr have acceptible offerings. Read the reviews at johnyguru, kitguru and hardocp for guidance.

PSU brands you should trust the power ratings and reliability of: Antec, Seasonic, Corsair, PC P&C, XFX, OCZ.
PSU brands to avoid at all cost: Diablotec, Bestec, Sunbeam, Logisys, Radimax, coolmax, and anything else that is priced too good to be true.

As far as PSUs are concerned, be informed. Before you buy any PSU read accurate, objective PSU reviews at reputable sites such as www.jonnyguru.com or www.hardwaresecrets.com on the EXACT model PSU that you are interested in as some brands have both good and poor quality PSU models.

You can also get an accurate rating of how much PSU power is required for your current or future system at the PSU calculator link below. Once you know the total PSU watts required then you need to confirm that the 12v rail has enough amps. to support your Vid card(s) and the rest of the PC system.

There are several websites that show the Vid card power consumption in watts. Divide the watts by 12 to determine the amps. required on the 12v rail(s). Add 15 amps for the rest of the PC on the 12v rail and you now know the Minimum total 12v rail amps required under full load. It's best to have at least 5-10 amps. reserve on the 12v rail available under full load so the PSU is not loaded to 100%.
It's also worth noting that people often misunderstand the 80% power rating. This is a rating of the PSU's energy efficiency not it's output. 80% plus PSUs use less grid power to produce the same PC power. If it's 80% Bronze, Silver or Gold the cost savings on electricity is pretty small between Bronze, Silver and Gold unless you are paying very high rates for electricity so any 80% rated quality PSU is fine even if not Gold. For those who leave their PC on 24/7 a quality 80% PSU is a good investment.
