I need to replace my PSU and this looks like a good one, Corsair quality, hybrid, modular (and I NEED modular) etc...
I wanna know your opinion about this PSU (BTW, I don't need a digital one so basically this one fits to me pretty good IMO).
Thanks for the helpers smile.gif

Excellent choice. I have a very similar PSU myself, and it has treated me well.

Yup. It's good. Warning: Review Summary (Click to show)
The Corsair Professional Series AX760 and AX860 power supplies are both excellent units which exhibit no weaknesses. They are beautifully constructed and based around an exceptional Seasonic based 80 Plus Platinum internal design.
These units are ideal for the discerning enthusiast user who would like to save a little over the recently released Digital ‘i’ supplies which feature the Corsair LINK interface module and proprietary software. The AX760 and AX860 are around £20 less expensive than the equal wattage ‘i’ series units. All models feature exemplary build quality and deep paint work which proves resilient against fingerprints and ham fisted handling.
As our testing has highlighted, both units when pushed hard will deliver much more wattage than their rating suggests. The Corsair AX860 managed to hold a 1000W load for quite some time which highlights that the internal design is pleasingly over specified.
Noise suppression and load regulation are admirable, and both units sailed through the intensive cross loading test without even a minor hiccup. On a technical level there is little to fault from both supplies, in fact finding a closing argument against a purchase proves rather difficult.
There are certainly cheaper options on the market, but in this case you certainly get what you pay for.
The pure modular design will prove popular with a wide audience of case modders who want to fine tune their cabling for ultimate appearance. The high grade 120mm Sanyo Denki fan is very quiet, even when dealing with a very high, active load.
The ‘hybrid’ mode will be well suited for the best part of the intended audience, especially enthusiast users wishing to build a system with minimal noise. The fan in both AX760 and AX860 won’t spin until the supply is facing at least a 50% load, dependent on the ambient temperature of the system chassis and surrounding environment.
These are excellent power supplies, but to be perfectly honest we expect this now from Corsair, their overall standards in a wide cross section of sectors have been without reproach this year. Both AX760 and AX860 ship with a seven year warranty and they are clearly confident that these units are built to last.
You can pick up the Corsair AX760 and AX860 from Scan for £140 and £152 including vat, respectively.
Pros:
Rock solid.
great build quality.
7 year warranty.
low noise.
ripple suppression.
load regulation.
pure modular.
quiet.
Cons:
They aren’t cheap.

You can look at this list for recommened power supplies. However, I don't think it is updated super often.

Good however unless you're using 3+ high end graphics cards it will be overkill.

No sir, only two 6870s.
It's a bit of an overkill (a 700W PSU is plenty for me as well) but I would rather have a future proof PSU

But running a PSU @ about 50% load gives greatest efficiency.

What setup/budget do you have?

Not true with modern, quality PSUs.

Future proof for what? Components such as CPU's and GPU's are getting more efficient with each generation. In fact what you plan really only calls for a 550 watt PSU.

While that is true, the notion behind it is a myth. Unless the OP is Folding 24/7 with CPU and GPU's then having such an overkill PSU for that "50%" will not work. The reason is because the computer will be idling most of the time and will only reach that magic 50% mark briefly in certain games and applications, otherwise the system will be drawing under 10 or 20% of what the PSU is rated for which is where the curve for efficiency falls off. So really you would be spending slightly more in your electric bill with an overkill PSU versus one that is actually fit for the system it's powering.

Here is the efficiency chart for PC P&C Silencer Mk iii 750w.
And here is the same site with power efficiency of the Corsair AX 860.

It doesn't require a lot but why not?
