850w in a media pc build? Sounds a tad overkill :smile:

The AX > HX. I'll take an EVGA Supernova P2 instead for this price. Not least because EVGA's customer support is second to none and the ripple suppression is unsurpassed, even better than this. Which is indeed a very good PSU. But you can't really go wrong.
As an aside, to require an 850w PSU you need a seriously hungry machine. You can easily easily run SLI GTX1080's on a 750w for example.

This seems like a really good price for the spec.
Theres not a lot that needs this sort of power these days though, I know I could comfortably run a 1080 off my 750w and SLI is on its way out.

I have one of these, flawless so far. Had to upgrade to solve a coil whine issue.
I don't think it's ever got warm enough for the fan to even run.

Good PSU but not top tier. As mentioned go for AX or EVGA if you can find one at a decent price. Can't comment on price of this as I've never researched the 850w bracket it's always been overkill on my builds.
I'd recommend the AX860 as I own one, but it's like £175.
Still can't believe I bought it for £127.99 in 2014.

I bought one (AX860) for £40 although it was from Gumtree second hand. Been using it problem free for a year now with 2 980's. I must have struck gold :smile:.

Lol yes it is... I should have checked. The HX was tier 2 previously so they must have updated the build!

still question so forgive me if my components are not using the full 800 it will not draw that much from the wall will it thanks in advance

No, it'll draw about 8% or so more due to efficiency.
As it's the i series you can monitor the input and output wattage from the Corsair link software.

No it wont draw that power. But do be aware that PSUs are efficient when drawing a decent percentage of the power they are supposed to. So if you are actually using 200W you would be better (more efficient) with a 430W power supply than an 850W power supply.

They must have changed supplier when they introduced the HXi series as the HX is Gold rated and the HXi is Platinum -
thanks bud just getting started in building a pc 850watt is over kill for me but am thing down the line it could come in handy

Heated, good price and a high-tier PSU, funny I found this thread though as I'm in the market for a new one as my 850i literally just blew a capacitor 30 mins ago and I've only had it a few months :disappointed: Worth mentioning after doing some research the capacitors on these are known to be of a lower quality than some of the competitors - I'm going to go EVGA this time round for the extra 25 quid

For anyone wondering, Corsair explain the difference between the AXi and HXi PSU's here - http://www.corsair.com/en-us/blog/2015/january/hxi_vs_axi
