ive just upgraded my GPU and something doesnt feel right

[heatonpkmassive]

yeah i'm in a position where i don't think investing into a new mobo is worth it i think.

5800x
3070 FE (soon to be 5070 Ti)
32gb
MSI Tomahawk
2560x1440 165hz display

When I can afford it I will replace mobo and cpu at the same time. i'm just gonna have to deal with the cpu bottleneck until i win the lottery

There'll be a bottleneck, but you'll still get a decent uplift in performance.

And if that board is the B550 version, it's the same one as in my signature. It's an excellent mobo, rock solid.

I'd just go ahead with the GPU upgrade and enjoy it.

Edit: We're actually running very similar systems. I went from a 3080 FE and was satisfied.

I think a 5800x3d would keep up with a 5070Ti no? Although you need to be careful about over-investing in an old platform, no matter how good the best of that platform's CPUs get.

Pcie 4.0 will never be a bottleneck to a 5070Ti. TechpowerUp found that a 5090 at 1440p gives 99% performance on pcie 4.0 and 96% on 3.0, Hell even pcie 2.0 got you 90%.

yeah i dont want to upgrade to the 3d version, i may aswell try save money for a new mobo in future. just worried if i buy the 5070 ti this week my 5800x is just gonna be a problem.

Hey guys, just want to double check. I will be buying the 5070 ti this week and I opened up my PSU to check my old PSU and it has x2 6 pins connector. So if I buy this cable linked below everything is going to run ok? Nothing will blow up?

Corsair have a cable compatibility chart (including a legacy one, for older PSUs) on their website, if your PSU is that old it only has 6 pins, I would be very cautious.

I have a 5800x3D with a 4080 on this MB. Works pretty well.

Now I'm back to being confused. I'm too dumb to understand. Would you mind helping me?

RMx Series™ RM750x — 750 Watt 80 PLUS® Gold Certified Fully Modular PSU

I don't know if it's the 2021 or 2018 version. The cable I linked above is bad? Why be cautious?

I was cleaning my PC this morning and took PSU out, it has x2 6 pins i think

Picture is maybe hard to see https://imgur.com/a/EjQYtVz

Yeah but I simply can't afford to upgrade CPU and it's a lot of money just to replace the 5800x for specific games to run better, right?

The reason I said be cautious is because a PSU that has PCIE 6 pins instead of PCIE 8 pins is very old and while type 4 cables are compatible with the majority of Corsair PSUs, with a PSU that old, all bets are off!

However, you just clarified that the PSU is nowhere near that old, so a type 4 cable should be fine for the RMx.

So I have nothing to worry about yeah? Sorry I have anxiety, just PSU and cables scare me I've heard a lot of stories.

If you want to confirm things properly it would be really helpful to have the exact model number, but I'm fairly sure that all RMx PSUs are compatible with type 4 cables. You can check this yourself on Corsair's cable compatibility charts.

The 6 pin PCIE still concerns me, can you check this?

From what I can see in reviews, these PSUs should have PCIE 8-pin (6+2 on the device end) cables and you should have at least 3 independent cables that you could use with the card's box adapter, instead of buying an extra cable from Corsair.

This cable was mentioned to me because apparently it's better than using the adapter. I'm going to take out the PSU again and have another look and see what I got, I'll try find the box and see if I got extra cables.

Ok so it seems like I only have 2 GPU cable slots anyway, so using 3 cables is not possible?

It depends what you already have plugged in. On the PSU-end the PCIE and EPS12v connectors are usually the same.

If you only have 2x PCI-E cables (with 2x connectors) each, that should still be enough for the adapter that comes with the card.

RE: the Corsair cable, you can see that your cables are stamped Type-4, so looks like you're good there.

Ok so it comes down to using the 5070 ti adapter or using the cable which was linked above. is there any downsides to one of them so i can eliminate as many problems as i can? because as of now, i will just use the x2 gpu cables and the 5070 ti adapter?


and forgive me if i repeat myself i'm kind of dumb, i just don't want to blow my pc up i don't have the money to replace it.


edit: wait, i don't think i have a gpu cable slot available, it's taken up by the cpu connector. i currently have x1 gpu cable and x1 cpu cable, so i'm fked?

Can you start another thread please, like "How do I power my new 5070 Ti ?" and include the pictures and description of your PSU.

You have 4x EPS/PCI-e sockets not two. Those two empty 8 pin sockets to the left are also for them. Sata & Peripheral are the 6 pin sockets. You only have a pair of pci-e cables each with a pair of daisy chained 6+2 pin plugs so you have enough for a triple 8 pin card or adaptor.

One thing I would do is give that psu a good blow through in reverse direction to the usual airflow, so in through the grill and out through the fan opening. If there is that much dust stuck to the fan grill there will be a lot more stuck to internal components which will degrade the psu's cooling performance plus excess dust in psu's have been known to start fires.
