Corsair HXi Series 1500 W

[Chrispy_]

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

4090 uses less power than a 3090Ti, and Nvidia have designed 40-series to have less severe power spikes beyond the power limit:

A 3090Ti is a 450W card, but spikes into the 600W range.
A 4090FE is a 450W card, and it never spikes above 500W.

Essentially, by fixing that behaviour and using it as a marketing point in their Lovelace launch events, Nvidia have confimed that their power regulation was awful on Ampere, and it's their own fault that all the 1000W PSUs caused their 320 and 450W cards to bluescreen by not being strong enough for Ampere's power spikes.

AMD have a similar problem with the 6900XT so I'm not just bashing Nvidia here, but we're talking 40-series as per your comment.

No?
No.

And uh, no.
The 4090 is even or worse to the 3090Ti.

This one breaks even

FE might as well be identical

Better. But the problem is exactly the same with spikes from 350W to 500W.

Were the advanced transient response tests done at 115 V or 230 V? According to the images it's 115 V, but that would be unusual around here.

It doesnt change anything as the transients are within the PC after conversion

Are you sure? Then why do reviews of the same PSUs (identical S/N) done by the same reviewer on the same date on Tom's Hardware and here show different results for transient response tests?

ask the reviewer

I somehow doubt that reviewer was in two countries at once testing at 110v and 220v/240v simultaneously

I noticed a direct short on the discharge IC - is this a fault or normal?

From what I'm seeing all of the 4 legs are on the same trace, so it doesn't really matter.

Does anyone have experience with the 2023 model? Does it still make that 'clicking' noise at low loads?

I have a 2023 model, and there are no clicking sounds, whatsoever

I do have that model too and yes I can confirm these clicks are still present, but only at system startup so does not annoy me at all.

FYI: At least in Germany there are two different models of this PSU sold. The older one without and the newer one including the 12VHPWR connector. Both have the same name. The reviewer had the older one. Also the older coplies to the older ATX 2.52 Norm whilst the newer one comlies to the newer ATX 3.0 norming.

I asked Jonny and Corsair support and the two units are the same, only difference is that one has the cable and the other doesn't.

I've been using the HX1000i (2023) since october, idle load is 76W (PSU Power Out), with Firefox 82-88W and 320-340W when gaming.

I tested it outside of the case too and I can't hear any clicking sound, I think my ears are pretty good since I find the ultra silent Noctua fans noisy.

indeed correct. My HX1500i didn’t have the “dual pcie-e to 12VHPWR” cable included, so had to buy it separately.

Where are the temperature sensors located? Are they loose ntc temperature sensors?
