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.

Just paid £94 each for three RM650i PSUs, wish i'd seen these yesterday.

Wasnt that 7 years warranty?

Perfect for my media pc, dont know weather to bite the bullet hmm

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

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.

I paid £126 for my HX100i

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.

Oos

At this price you really can't go wrong.

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.

It's in the same tier as the AX according to your link.

​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 :D.

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

They must have changed supplier when they introduced the HXi series as the HX is Gold rated and the HXi is Platinum -

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.

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

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.
