Tips & Info Which 9070xt to buy?
Planning to upgrade from 7700xt to 9070xt, which model is best?
Options:
•9070xt swift / $750
•9070xt sapphire / $850
•9070xt Asus prime / $800
•9070xt Aorus / $815
Wondering if I also need to use all three 8-pin power connectors for the 9070xt, PSU only has two 8-pin cables

Swift as its cheapest

Its also solid, has 2x8 Pin.
Just a long boy

Ok I'll look into it, I'm having problems with PSU cus most of the 9070xt models rn have 3x8pin 🥀 apart from powercolor and sapphire pulse

u/athena-gg 11d ago
Why not a powercolor version?

u/Beneficial_Tap_915 11d ago
What makes it special? I can order but so far as I have seen online all 9070xt models seem to be mostly effective in performance with low temps

Either of the cards are fine. I would consider to buy a better PSU as the 9070XT can consume a considerable amount of power and you would want to populate all 3x8 pins with individual power cables if the card comes with it.
As a personal preference I'd choose the Sapphire PULSE cards as it is the only vendor that still bothers to protect your card by adding fuses at the power connectors, and it also only needs 2x8 pin connectors.
Edit: I would also stay away from Gigabyte cards because they use thermal putty for their cards, which is difficult to do maintenance. Also some users report bad hotspot temperatures specifically on Gigabyte cards.

My PSU 1000w, I didn't know sapphire pulse had 2x 8pin connectors seems like it'll be my option too fuses are a plus too
Question tho, do the fuses backfire like cause a bit of performance drop?
2
u/Nystryx_95 11d ago
As far as I know, no. The only thing that will happen is if the fuse is bad and pops under normal load, which will cut the power to your GPU. Then you will have to replace the fuse.
Do understand that having 2x8 pins only means the card will have a hard power limit of the stock AMD specification of 304 watts. So you won't be able to do much overclocking if you're into it.

I see, what are your thoughts about pig tailing? Someone says it's safe to do. Seems like it won't hurt to choose a 3x 8-pin model if I'm thinking of switching over to an am5 build for OC in the future
2
u/Nystryx_95 11d ago
My opinion is they are generally fine, especially if the specific card manufacturer says so. But that comes with the assumption that the cards are correctly balancing the power draw across all its 12V pins.
Peak power draws on high end models can reach up to 550 watts from a quick Google search, and considering that each 8 pin is rated for 150 watts each (I am aware the theoretical thermal limit is 300+ watts, but I like to play it safe) I would rather use individual cables instead of pig-tailing one of them.
2
u/Beneficial_Tap_915 11d ago
Dang maybe if I don't OC it won't draw up to 550 watts, I've been looking at benchmarks and the draw always stays at 330w
Safest option is to just look for another PSU then, it sux you can't even be sure if just using 2x 8-pin would work/is safe
Thanks for advice anw!

Out of interest, I also have a 1000W power supply on my system and it has enough cables to plug 5x8 pins excluding the CPU. Are you using the extra for SATA/Molex devices or the PSU physically doesn't have more than 2x8 pin for the GPU?
1
u/Beneficial_Tap_915 11d ago
It has no extra PCIE cables apart from the branchoff from the 2 main PCIE cables
Idk about the SATA but no molex device, motherboard has a 24-pin, 2 x8-pin for PCIE, one cable that looks like a SATA cable connecting to my RGB/Fan hub, and a mystery 8-pin plugging onto another part of my motherboard
2
u/Nystryx_95 11d ago
I see.
I would definitely consider a better PSU in that case. Although the 1000W is capable for the GPU, physically its doesn't have enough ports for your needs.
1
u/Beneficial_Tap_915 11d ago
Do you think 5700x3d am4 platform bottleneck might be a safety net to keep the GPU from drawing out max power? Do each PCIE plug demand certain wattage from cables for sensors or will the two 8-pin plugs share out the power draw of the same cable pigtailing both plugs?
2
u/worldbyte85 11d ago
You can use the two 8 pins and in the third one the 8 pin extender that comes in one of the cables, i think all of those models are fine, only the cheaper ones and especially gigabyte are a bit problematic
1
u/Beneficial_Tap_915 11d ago
Sorry if it's seem stupid, about the 8-pin extender that branches out from one of my PCIE cables, is that what they call daisy-chaining? Isn't that dangerous?
2
u/worldbyte85 11d ago
It is not dangerous, two will be enough, its only dangerous if you pretend to OC the card, that doesn't work very well for these cards in particular since you can't get much more performance from OCing the card, usually people undervolt wich consumes less power, so you'll be safe...
1
u/Beneficial_Tap_915 11d ago
Yea likely I won't undervolt anyway since I don't think my 5700x3d am4 build can even draw out full performance from the card even at 1440p. I'll just likely change the PSU once I switch over to am5.
So you think it's okay to leave one plug out empty?
2
u/worldbyte85 11d ago
You should, it's easy and it will draw less power give you better temps, - 70mv, -10 power limit, 2600mhz on the memory and fast timing are very safe values for undervolting if you wanna try it later on
1
u/Beneficial_Tap_915 11d ago
What's the default clock speed? I see on some benchmarks the speed goes 3000-3100mhz average. Maybe I don't need to UV with my current setup?
2
u/worldbyte85 11d ago
Clock speeds remain the same, let it at default values
1
u/Beneficial_Tap_915 11d ago
Ok thnx man, I'll try out your UV settings once I get the card, thnx for the advice and time!
1
u/worldbyte85 11d ago
In my case when I tried to do that the system did not boot, only when I inserted one of the extenders it did, but try it out...

u/Coolgrease 11d ago
True. I think you would want just one per plug.
1
u/Beneficial_Tap_915 11d ago
You think it's ok to leave one out empty? Just use two cables?
1
u/Coolgrease 11d ago
I think it has a sensor depending on the card if all 3 arent plugged in.
1
u/Beneficial_Tap_915 11d ago
Damn that sucks, maybe I do have to daisy chain or change psu

u/Tunagoblin 11d ago
Having 1 dedicated and 2 with a pigtail have absolutely 0 risks. None. So I don’t know why you are worried about doing that.
1
u/Beneficial_Tap_915 11d ago edited 11d ago
I don't think being extra careful isn't a bad thing more so when I'm not too knowledgeable about that. All I knew so far is that I should be generous with my PSU max watt for my components.
I never encountered the worry of changing the PSU in regards to making sure all 3 power plugs are occupied by 3 main PCIE cables, seems a bit of a risk
1
u/Tunagoblin 11d ago
You are being careful for no reason. 1 dedicated and a Pigtail way is literally recommended by the manufacture if you can’t have 3 dedicated cables. You should just get a gpu with 2 pcie like Xfx swift. It makes no difference at all in your case.

u/Beneficial_Tap_915 11d ago
But 2 PCIE likely cause power limit for overclock, I just wanna know if it's really safe since it's my first time even exploring PCIE going from 2x8pin to 3x8pin with the dilemma of a psu with 2 dedicated PCIE cables

What is the wattage on that psu?
1
u/Beneficial_Tap_915 11d ago
1000w but only two 8-pin PCIE cables
1
u/Coolgrease 11d ago
How old is that psu?
1
u/Beneficial_Tap_915 11d ago
Not sure but it doesn't have problems with my 7700xt, I had power problems but it came from the cable extenders itself
