Corsair Releases the HXi Series Power Supplies

Announced at Computex in June, Corsair's HXi family of 80 PLUS Platinum-certified power supplies has now become available. The three HXi units (750 W, 850 W and 1000 W) feature a fully modular design, 100% Japanese electrolytic capacitors rated at 105°c, Corsair Link support, a 140 mm fluid dynamic bearing fan backed by the ZeroRPM mode (so the fan doesn't run at low loads), and over-voltage, under-voltage, over-power, over-temperature and short circuit protection.

The HX750i, HX850i and HX1000i PSUs are backed by a 7-year warranty and cost $169.99, $189.99 and $229.99, respectively.

I wish they've released 500-650w range PSUs for this series as well.
I'd love to have the solid performance of AX1500i without spending 400USD for the power I won't ever need for my single-gpu no-overclocking setup.

Really when you're looking at solid PSU's the performance difference between each is generally so small it's not really worth nitpicking.

Besides, there's the LZP-550 which fits all your needs. It lacks a DSP however that doesn't really matter to the end user.

Being extremely picky is quite standard thing for lots of PC enthusiasts these days, don't you think? :)

Speaking of LZP-550, I'd point out not the stablest voltage regulation (most of 80+ Platinum PSUs are better in this area, especially more modern ones), and unknown fan used in it. What type is it? Sleeve which'll start whine after a year or two of usage? Ball-bearing with its rattling? I could come up with more cons if I'd like to , but I won't :)

No, I just bought RM1000 for the price of RM850, but it is yellow and this one is blue. I want blue and Platinum.

No, I don't think so. Your not so stable in voltage regulation point isn't true in any way at all if you look at how it performs in the reviews. And the newer platinum units aren't "more modern" than it as they all feature the same LLC resonant topologies. Yeah, it doesn't have a DSP but then again, no PSU of that size has it.

Sleeve bearing doesn't mean the fan will start whining after a year or two of usage. I've had many cheap fans last for years without any issues. Sure, they can be problematic, but they're usually fine. And what's wrong with ball bearings? You do realize the San Ace 120's used in Seasonic Platinum units are ball bearing, right? And that they're regarded as some of the best PSU fans around?

Instead of buying gimmicks or a relabeled PSU, just buy a Seasonic and get the best quality PSU at the lowest price right from the source.

.. and almost certainly get the loudest cirquitry buzz/whine and loud work at medium to high workload. brilliant.

Its regualtion is -3%/+3%, which is fine, but is nowhere near <1% overall demonstrated by the best PSUs. Its fan may be good, and may be problematic, and I don't even want to find out actually. My bad about ball bearing fans. Some of them are great of course. Never had a sleeve fan with no issues though.

It's more than just "fine". You don't need near %1 regulation demonstrated by the best PSU's. And you not wanting to find out doesn't matter to most as time has shown how many people have been satisfied with the LZP units.

Ignore Jorge, he's an asshat. He does not understand the concept of OEM's. Or the concept of concepts.

Anyway, how about the Seasonic fanless models? Seems to be pretty good.

Where did you get that crap from? I have a Seasonic X750 that is silent until it is under a load and then the fan is barley audible.

I read that certain batches have problems with coil whine (meaning, there are also batches that are as silent as they should be), so you might want to get them from a good store that lets you get a replacement when yours turn out to be whiny.

If you happen to get a Seasonic with coil whine, Seasonic will warranty the unit. Very rare to be honest. I think that Corsair had more issues with coil whine in their power supplies than most.

for sure older Corsair PSU is not the best on the market, but were very good for the price (owner of TX850v1)

anyway fan's psu are often over-rated for the work that are meant for... psu vendor usually prefer put faster fan than made proper coling for hot/sensitive components, for a mid sized psu (750-850W) a 1200-1400 rpm 140mm fan is more than enough (at least in a 80+ or better psu) if it have 12v mosfet heatsink and 105°C capacitor.

btw voltage regulation is not so relevant if the psu haven't a good transient response ;-) or low UPS compatibility :-D

If I recall, HX is a very old line, it dates way before AX. However, this is HXi, with this "nothing-of-use" usb feature. :)
