Corsair HXi Series 1500 W

[crmaris]

The Corsair HX1500i has good performance and top-notch build quality. Designed with extended functionality through Corsair's iCUE software, you can monitor and control some of the PSU's vital functions. Lets see how the PSU fares through our comprehensive review!

Hi, thanks for the review.

In the 12v vs minor rails graphs for fan noise, it seems to show <6dba operation solidly <800w from 12v. Yet in the graph right under it, it shows the area doing 400-600 RPM on the fan. Does this mean the PSU is not 0RPM at <800w and the microphone couldn't really hear the sound?

I'd want a free 12VHPWR GPU cable with a newly released 400 dollar PSU, hopefully they do add it in sooner than later.

If on the off chance it didn't come with one. I would hit up their cs, facebook etc and you shouldn't have a problem getting one.

1.5kW HX maybe..

iClueless OTOH....

nope..
notta....
no way 'Jose !

This forum is as close as any of my rigs will eva get to that crash-test dummy p.o.s. crapolia

 

[Alan Smithee]

Agreed that paying $20 more for a 12VHPWR cable on a $400 PSU is adding insult to injury. Total BS, Corsair.

Noctua offers free upgrade kits for new CPU sockets, Corsair should take a clue from that.

 

[Godrilla]

Is there any advantage of waiting for ATX 3.0 Psus besides a cleaner cable management look?
Also anyone know of any good braided 12VHPWR adapters for color coordination or do we have to settle for black?

You don't have to use that crap you know that?

1500 watt PSU
"Good performance"


I haven't read the review yet, but that alone has bells ringing

The pair of bridge rectifiers can handle up to 50 Amperes.

Right, time to back that claim up - but how are you gunna fit 50 GPU's in the one motherboard?


I'm not sure if this is an industry standard design or something, but i cant make any sense of this. It looks like MS paint drawings of a house.

PSU definitely doesn't require iCUE, but no testing at all of how the software works?
No comparing it's readings vs external ones for how accurate they are?

You dont want adaptors, period. You want a native cable, which means it has to come from your PSU manufacturer specific to your PSU

The Corsair adapters are actually just that. JG explained how they worked more specifically in another thread but I cant remember off hand what it was. I'll try to find it.
Edit- I couldn't remember the the thread. Your right, aftermarket cables are generally trash. Cablemods are the only ones I trust implicitly with my gear. I've used several sets of their cables so far.

Of course I know that, but I was merely expounding on the fact that I would not

 

[Ferrum Master]

The soldering quality is mediocre at best...

A unit costing so much should have any issues. A hasted product...

 

[crmaris]

The fan speed at low speeds, 400-450 RPM, is close to our chamber's ambient from a one-meter distance.

Ahh thanks. I think what confused me is 2 pictures above, it shows RPM/Temp delta graph and it shows 0rpm until 780w.

If RTX4000-series no longer have the power-spike issues that Ampere did, and SLI is dead - is there really any need for 1500W PSU?

I get that it's a nice unit and all, perhaps 4090Ti and 13900KS LN2 people will be buying something like this but that's a miniscule, niche market of maybe a few hundred people, most of whom will be given PSUs for free for sponsorship/exposure deals as many of them are full-time streamers or compete at events and are provided the hardware for free by the event organisers.

Cablemod makes full 12VHPWR cables that go from the PSU right to the card. They have cables available for Asus, Seasonic, Evga and more coming too.

12VHPWR PCI-e Cable – CableMod Global Store

And no I do not work for them, I was simply looking if there is an option to get 12vhpwr native cable for my Evga supernova g6 and found them.

I swear I couldn't find any on their site the other day! Ah, the global site. The other site 404s out. Nicely done ZetZet!

Cablemod are the only aftermarket cables I trust. I've got a set for my px-850. They are the real deal. None of that cheap, chineseum junk amazon sells.
Too bad they don't have the color I need! Yeah right, as if I were buying a 4090 anyhow pfft.

They already have the 12vhpwr option in the custom configurator, more colours there and it's not that much more expensive.

Passive or inaudible fan speeds up to 800w for very noise sensitive people.

True, for the PSU in isolation.

The problem is that if you need "up to 800W" of power in your system, the PSU is NOT in isolation. The other components in your system are going to require some VERY active cooling. The case fans, pump, and radiator fans to handle 800W of heat dissipation are unlikely to be silent, so having a silent PSU is completely pointless. Even a dual-420mm radiator setup in a case big enough to handle that is going to make audible noise. It won't be obnoxiously loud, but the laws of physics can't be broken, so it's definitely going to be audible. There's no getting around the fact that removing 800W of heat whilst keeping components within 50C of ambient isn't trivial.

I use 3x560mm. I can scale it up if needed. Dual pumps or more, then rpms can go below what my ears can hear. With rads external to case, passive psu prevents a lot of dust accumulation in the case.

<500RPM I find it hard to hear fans even with 24 fans on my rads. It takes cooling that is significantly louder than PSU for PSU's noise contribution to be immaterial. A lot crazy things can be done, it's just a matter of interest and resources.

I dunno why people keep bringing up "laws of physics" like I'm trying to jump off a building and start flying (though airplanes exist). A lot crazy things can be done, it's just a matter of interest and resources.

Lol, you are the 0.001% that this PSU is aimed at.
24 fans.

My loop has four fans on it, and my entire system has "just" nine fans in total. I also hate fan noise but I make fan curves from 600 to 1100rpm for 120mm fans and 500-1000 for the 140mm ones.

For what it's worth, I'm using an RM850X and I've yet to make that fan spin. Presumably I wouldn't be able to hear that PSU over my case fans until about 600W, but don't know for sure because my 5800X and 3060Ti only pull 350W from it.

My 1000w EVGA P2 can come on sometimes, though depending on the game maybe not that often (3080ti). I was thinking Seasonix TX700 since it's passive so dust and fan noise is a none-issue. But especially a few months ago when everyone was saying how next gen GPUs are gonna use 600w standard and some were saying there's a top secret 800w GPU in the works, 700w for entire system all a sudden felt limited. With hx1500i there will never be any issues with amount of power it can supply including excursions. But ehhh.

The true endgame for me is moving beyond watercooling and moving back to air cooling for maintenance, but move computer to another, sound proofed room. That's fine and dandy but I'm not currently willing to remodel the house over it or buy a new house. It'll happen one day, but not today.

Also my 9yr? old PSU is perhaps showing some signs of age. New coil whine issue, where if GPU is at moderate but not full load, GPU/PSU exhibit coil whine. So it has me thinking it might be time for a new PSU.

But PSUs seem to have gotten more expensive than several years ago and I am a little underwhelmed with how far PSUs have come in last decade.

Solution for most people: Used closed back headphones.

40 series cards seem to have stupid high wattages, as do modern intel and AM5 CPU's


So yeah, it may be needed for certain builds.
