While I didn't buy this product from Amazon - it was £30 cheaper on another site - this is where I found it and I'm returning to mention just how good it is.

Firstly, the efficiency rating. Obivously this doesn't have any impact on the actual 'performance' of the supply, as such, but it's worth noting that a higher rating does draw less power from the socket, runs cooler, and shaves some money off the electricity bill. This is obviously rated platinum, which means it's rather efficient. So that's a plus. 80 Plus Platinum, in fact.

As you can see from the description, it's got a pretty hefty 12V rail so it's pretty much perfect for two high end cards, like GTX 680s in SLI, which is what I plan to use it for. It's obviously overkill on a single card system but I don't think anyone who's done any research would buy a >£150 PSU for that.

But by far the best feature is the hybrid cooling mode. It's not made entirely clear in the description how this works. Essentially the PSU operates without the fan running up to 30% of its maximum load, being cooled entirely passively and silently. But I've never heard the fan kick in, and yet it must have at some point because I've had zero heat problems with it. I guess the noise is just getting lost behind all the other fans. Whatever the case, it's great to have the low noise of a silent PSU combined with the raw power of an enthusiast-grade supply, especially since I'm coming from an older Corsair power supply with a noise level somewhere between desk fan and vacuum cleaner. There's even a 1000W version with the same cooling system for all you nutters out there.

One thing to note is that it's slightly longer than the standard form-factor for PSUs.

It took them absolutely ages to send off this item. It was the last one a received out of all the parts for my gaming computer. It took them about a week and a half to actually ship out to me.

VERY IMPORTANT- MUST READ:

When I had finally finished my build and came to plugging in the computer, I soon came to a massive problem. Due to this being shipped from a European country, it has a EU socket, so luckily they supply you with a UK adapter to fit on - BUT, the flipping thing was the wrong fit. So, unless you can't find an adapter like I couldn't, I had to get someone to chop the actual socket off of the cable, then wire a new UK socket onto it. That process only took a few minutes for the guy to do and only got me £1.50, but it's just the fact that I had to go through all of that trouble, just because they supplied the wrong adapter.

All in all, after all of that, I have had no troubles with the actual PSU so far. Just disappointing that they messed me around at the beginning.

It's a great power supply.
My first one arrived dead on arrival at my house (which is very unlike SeaSonic by the way) but I had a new one on my doorstep within 4 days. Brilliant service from Amazon once again. Nothing in my PC was killed by the dead PSU at all (a real testament to good design) and the new one is just fantastic.

Watch the wattage though, most people really don't need this sort of power, even if you are doing SLI or XFire.
You should aim to get a PSU that has double the wattage that you will be normally using, example: your PC normally uses 250W most of the time, so get a 500W PSU.
50% load on the PSU = optimum efficiency as a rule of thumb.
