Show off your 5090s thread!

After having a 5080 for 2 weeks I had to get a 5090 :D

Mine arrived today...
I'm just testing it at the moment because my new PSU hasn't arrived yet so it's only on a 850w Loki

I'm using a CableMod 12VHPWR direct to the PSU because the one that came with the Loki is too short, but even this one I need it twisted at an awkward angle.
I'll move everything into my new case tomorrow... For now I've set a power limit of 80% which is limiting the power to 460w, similar to what my 4090 was using so I don't foresee any issues while waiting for my new PSU.

There is definitely more coil whine than my 4090FE, but I imagine that will fade a bit. I'm pretty sure my 4090 used to whine more than it does now!!

Is that a laminated Conker’s Bad Fur Day instruction manual?

Lovely setup and love the 5090 FE look. I’d be bit worried about using a third party cable, are you not worried about cable melt? Recent YTubers have put the fear of god in me…

@no_1_dave enjoy your set-up!

I’m mindful that depending on which specific Loki you have you might be combining:

1) a old H+ connector on the PSU - if you tell us the very specific model we can help you figure this out if you’re not sure… me and @Absolutely Clueless were looking at some PSUs in DMs yesterday and the short of it is that whether it has a H+ or H++ socket is sometimes not very obvious at all;

2) a third party cable;

3) ASUS and their warranty schenanigans.

I’m not sure what Nvidia are saying in their manual re: using third party adaptors but if they are specifically saying use their octopus or use whatever comes with your PSU, I’d be cautious.

If you do have a H+ socket on the Loki it might be a good idea to use the Nvidia octopus adaptor instead, as ugly as it is. But you can also just inform yourself of all of these things to look into and then take a view / accept the hopefully low risk… up to you! :)

Nah, I've seen videos and kept up to speed... I used this cable on my 4090 for the last year with no problems and I've limited my 5090 to roughly the same power draw until my new PSU arrives next week

I also scientifically tested for heat by putting my finger on the connector while running Furmark and it wasn't heating up much, just residual heat from being next to the hot fan shrouds :)

It's the 850w Asus Loki, White Edition
It's probably just an H+ on the PSU side because I've had it over a year

I'm using a full cable from CableMod, not an adaptor and it worked nicely with my 4090. But with my PSU being only 850w and the fact that 2 of the melted cables on reddit are from Loki's I've limited the power to 80% so it's in line with what it was drawing with the 4090... In fact, the only 2 games I'm currently playing are World of Tanks and Stalker 2. WoT was drawing only 198w and Stalker was only drawing 340w so I'll be fine until my new PSU arrives on Monday or Tuesday :)
 
@no_1_dave sounds a sensible mitigation. For the sake of being exhaustive, limiting the total power draw is resolving about 1/4 of the issues with this topic. The other problems are:

i) old cables from the H+ era having manufacturing defects unrelated to spec (see here for the ‘way to sort it’ - i.e. buying a new cable - and here for showing the sorts of problems I’m talking about)

ii) an increased chance of something going wrong because of defective pin lengths of H+ (see seasonic’s vid on the changes here - good visualisation).

iii) the H+ PSU socket not having the H++ safeguards to limit power draw (see here - this one is new to me but it’s pretty major IMO and it’s not obvious at all!!)

(Sorry - I’m very aware how much I’m doing this topic to death and it’s a bit overkill :o but these things simply aren’t obvious and I just want to make sure people are making informed choices! As I say at work - an informed choice taking into account the type / range / scope of risks is fine and OK with me :))

I know, you're just being helpful which is what is so great about this forum :)

You want me to alarm you even more?

The CableMod 12VHPWR cable I am using, bare in mind this was after the whole '40 series melting issue', does not have sense wires that run the full length of the cable. The pins are there so they're detected, but they terminate to nothing, or to themselves.
When I questioned this with CableMod at the time, here was their responce:

Hey Dave,

Our 12VHPWR cables do not have sense wires. The sense wires used to cause problems so we have revised our 16 Pin connectors. We have fixed the issues that occurred before. The new cables are safe to use. :)

If I can assist you with anything else, please let me know. Have a great day!

The cable has been fine, but I've always kept an eye on it
My 4090FE is one of the models with the revised 12v-6x2 (H++) connectors, not the original H+ connector which was more prone to melting
 
@no_1_dave hmm I can’t quite fully process what not having sense wires actually means… but it seems intentional!

Having the H++ at the GPU is good but it doesn’t help out if there is any issue at the other end. But you’ve clearly figured that out, thought it through and done your own investigations etc :)

Enjoy messing around with your card! I’m dead jelly :o
