Hi All,

Now that people have had the chance to assess actual performance v Nvidia BS pre sale data, is there any worthwhile upgrade path from a 7900XT for under £1k?

Not really, even the 5070Ti that's arriving next Thursday (starting from 750usd and going to get real close to 1k usd for "high end" versions) doesn't offer that much more performance over a 7900XT or 4070Ti Super.

OK, I got my 5090 FE delivered a few minutes ago. Ive got an NZXT C1200 PSU which comes with a 12vhpwr cable which says 600w on it - I can just plug that into the 5090 right and it should be OK is that right ? I've not been keeping up with any of this cable talk so forgive my apparent ignorance. I ntoice that the 5090 comes with some kind of adaptor - which to use? Any help gratefully received!

With my 4090 FE I used the 4x8pin to 16pin that came with it, from Nvidia. My line of thinking was that if I need to make a warranty claim then Nvidia couldn't bail on me by saying it's because I used a 3rd party cable instead.

That's not to say all card maker's bundled cable are safe, it's just one potential less hurdle in the event of a warranty claim.

You will be fine with the PSU provided cable (12vhpwr), noting that cable does not fit as perfectly as the updated 12v-2x6 cable. That is to say, the latter cable had some minor refinements to the pin lengths to ensure a superior fit. These are seriously fine margins..

Thanks for the info - so my PSU only has 3 spare PCIe sockets as one is being used for the CPU - what should I do now? Thanks again for ay help

you use 12V HPWR Cable direct from your PSU to Graphics card.

(The only other option you have would be to use the included adapter, and then use the 6+2 PCI-E cables, but you'd have to use both connectors of each branch, which would probably be a worse option)

OK cool - thanks a lot.

First GeForce RTX 5070 Ti cards at MSRP spotted at retailers, all two of them - VideoCardz.com

RTX 5070 TI at MSRP and not We have some updates on RTX 5070 Ti in Europe, thanks to the multiple tips we received. The RTX 5070 Ti is set to launch in just 6 days. NVIDIA confirmed the official launch date yesterday, playing on AMD’s nerves as they were waiting for the very last […]

A grand + for a xx60 class card. I really don't have the words..............

let us know how you get on, ive got the same 1200w psu. Is yours the 3.0 or 3.1?

if youve got the box still should say on the side. Also the gpu cable should have H++ for 3.1 and H+ for 3.0 i believe

There might not be much in it but IMO:

(I) using a octopus adaptor provided with your 50 series GPU (connecting into x4 6+2 PCIE cables); is probably better / safer than

(II) using a single native 12VHPWR cable that plugs into a 3.0 PSU that has a H+ (old) socket.

With (II), you are still introducing a ‘well known to be problematic’ socket into your set-up. If you use a single cable (no adaptor) and want to plug into a single socket on the PSU, that socket really ought to be H++ (new standard for 12VHPWR) if you want to do it safely.

Can anyone recommend a decent ATX 3.1, 1000w power supply for the 5090 that comes with enough PCIe cables to use the adapter that comes with the card?

I was looking to get another seasonic focus but it only comes with 3 PCIe cables, the Corsair comes with 5 I think but I’m not too sure about them now.

NZXT C1500 should be able to do it, natively with a single cable or with up to 6 pcie cables.

However, see the posts in this thread from me and @TheCarcassKing from yesterday evening and today on the quality of the single cables supplied by NZXT.

Alternatively I would be looking at what MSI is offering, as their yellow cable ends seem to be absolute tanks / well-made.

id aim for a bit higher than 1000w to be on the safe side. 1200w minimum. Ive currently got an NZXT c1200w, but was hoping to return for their 1500w psu which comes with 6 6+2 cables and 2 12v-2x62. Other than that, have a look at the psu tier list and choose your pick from there which suits your needs.

Worth noting what @Nitefly said above, our cables we have checked arent perfect, not terrible but not great. So take that in mind aswell. Its still early days for if this is a cause, as not much info has come out proving anything

100% agree, however if it he uses the Octopus, I think he said he only has 3x dedicated PCI-E cable branches - therefore he will have to use 2x 6+2pins from the same branch, potentially pulling 300W+ through that branch

Nitefly · 2025-02-14T12:59:14+0000

@Armageus ah I see in which case apologies for making it more convoluted, I haven’t been paying sharp enough attention today.

Tbh I would not personally be comfortable with using 5090 via a single cable solution into an H+ socket at this point. If I didn’t have enough PCIE sockets to use the adaptor supplied with the 5090, I would probably opt for a new PSU.

pretty sure the 1200w i have only has 3 6+2 non branched cables so wouldnt even be an option sadly, not that id recommend it if we could

Corsair (usual ODM CWT) make good PSUs. Although their 12v cables may or may not be dodgy. An HX-1000i-1500i fits your needs, and you're only going to be using the PCIe 8-pins, not the 12V-2x6 connector.

If you want to avoid Corsair, the ROG STRIX 1000w Platinum comes with six PCIe and CPU 8-pin ports, and four PCIe 8-pin cables, whilst the ROG Thor 1000P2 Gaming has eight PCIe and CPU 8-pin ports and eight (!) 8-pin PCIe cables.

He should have the 3.1 since he mentioned having 3x PCIe left after the cpu is connected (which needs two)...

Top = 3.0
Bottom = 3.1

If he has the 3.0 then he would only have 1x PCIe remaining.
