The HX series from Corsair paved the path for others to follow and while many have caught up to this elusive model, Corsair have just released a power supply that has blown everything out of the water, and then some. The AX1200W power supply from Corsair isn't just their best unit, its easily the best power supply on the market right now and we think it will be some time before we see results like these again. We were so surprised with some of the results that we reran them multiple times over a period of several days – just in case our eyes, and testing equipment were playing tricks with us.
The efficiency ratings are off the charts, with results over 93% between 600 and 900W and over 90% even at full load. These really are staggering results which we never thought we would see, not for some years anyway.
Ripple is class leading, there is no doubt about it and most of the time the rails just hold a flat line, as if its just died on the test bench. Rail stability is another of the many strong points with miniscule movement even under heavy cross loading.
When you see a KitGuru lab technican with an incredulous smile on his face as he says “Hey, this is holding at 1545W!” you realise that this is something very special indeed. It is a modern day work of art. It would have scored 10/10 but we have to leave a little room for their next unit, because as incredible as it sounds, it might be even better.
The only downside is the asking price – Scan in the UK are taking preorders and it will set you back £245 inc vat when it is released next month … which to be perfectly honest is actually a very good price for a unit which has redefined just what is possible from a high end power supply.
KitGuru says: Redefines the high end market.
well thats pretty good then 🙂 I could buy a system for the price of that power supply, but you gets whats you pays for 🙂
Read a review of this last week and it does seem pretty much the class leading PSU on the market right now. Very good review and an even better product !
Looks basically like the perfectly power supply. I wonder will the power draw will ever stop, our electric bills will be scary in a few years if they keep growing exponentially
£250 for a PSU. dear lord ! but I guess if you want to run 3 way SLI or Crossfire X on 5970s, its the way to go. Just dont send me your electric bill :p
I think KitGuru needs to hold a competition for this ! what a product from corsair.
The efficiency ratings are ridiculous, I didnt even think a reading over 90% at full load was possible.
Way out of my price range, I thought the Thermaltake reviewed a while ago for £100 was expensive enough. Then again im not running Sli x3 or something insane like most of the people here.
I have a preorder in for one 🙂 wish me luck getting it, whenever
I agree, it pretty much is a modern day electronics work of art, nice conclusion text
Corsair I think have just kicked PCpower in the teeth with this one. Wonder if there is a response from any other company. I would find this hard to beat, or even equal.
This is a master showcase actually of how advanced flextronics are. I remember when this partnership was announced and people though Corsair were off their heads working with these relatively ‘ new guys’ on the scene. Oh how they have proved everyone wrong. amazing results, and I read the johhnyguru review last week, seems to be a no lose product, well apart from your wallter, being emptier
As I said on the forums, this is a showcase of just what is possible from a company so clued into the market that they can produce something to embarass everyone else. I doubt we need anything approaching this power for our systems, but for the 1% who need and want it, its awesome
I have been waiting for this to be released. come on corsair get it out the door !
I have had a 650W corsair PSU now for 2 years and its been flawless. I would highly recommend corsair as a company and their products are fantastic. Good to see product reviews on kitguru.
Most impressive indeed. I shall order one for my next killer high end gaming system which will put all of yours to shame.
Expensive but that’s a serious product
Corsair have certainly delivered with this beast
Excellent review thanks
I’d love a new power supply but I might aim a bit lower than this!

It’s not available yet 🙁
They make some great products, I would buy this when it comes out really because I have skimped on power supplies for years and I have to replace them yearly, it’s a false economy

Just to start, the standby efficiency was outstanding, being one of the best performers in this highest-end clas .
