Question: Cabling between be quiet! Straight Power 11 Platinum 850W, completely modular, and an RTX 4070ti
Hi.
Please keep it simple! The PSU is a straight Power 11 Platinum 850W, fully modular.
Link: https://www.amazon.co.uk/gp/product/B083..._qh_dp_hza
I need it for an RTX 4070ti.
I asked on Amazon if the PSU comes with all the necessary cables to connect to the 4070ti.
The reply was clear: if you're looking for the 12VHPWR cable, it won't work. My 1000W model didn’t have it either. Searching 'BC072' on Amazon shows it's meant for 4080 and 4090 models, not the 4070ti.
With this PSU, would I need to purchase a different cable for the 4070ti? Which one should I choose?
Thanks in advance for your assistance.
Which particular version of the 4070 ti are you interested in buying? Mentioning the "xxxxx" graphics card family usually means you need "xxxxx" cables, but it's often not possible since within the same tier there can be variations—some need no extra power, others require an 8-pin, a few need just an 8-pin pair, and others might need three 8-pins. Knowing the exact model is essential to understand the specific requirements for a given card.
Hi
Darkbreeze
Apologies, I only saw the reply recently.
Thanks a lot for your assistance.
The GPU options available are:
MSI GeForce GeForce RTX 4070 Ti SUPRIM X 12G Gaming Graphics Card – 12GB GDDR6X, 2790 MHz, PCI Express Gen 4, 192-bit, 3x DP v 1.4a, HDMI 2.1a
or
MSI GeForce RTX 4070 Ti GAMING X TRIO 12G Gaming Graphics Card – 12GB GDDR6X, 2760 MHz, PCI Express Gen 4, 192-bit, 3x DP v 1.4a, HDMI 2.1a
Sorry for the lengthy details. I thought I could have just mentioned "Suprim, etc." or "Tri etc."
But more information would be useful.
My motherboard isn’t ideal. (MSI MAG B560M MORTAR WIFI Micro ATX LGA1200)
However, I’m planning to upgrade my i5 11400f to either Core i9-10900K or Core i9-11900K.
It’s unusual but the newer models have a higher review score and higher clock speeds.
Although they’re from an older generation, they seem better.
I checked Parts Picker and everything looks compatible.
The rest of the setup includes:
- 2 SSDs
- 1 HDD
- 4 case fans
- 64GB DDR4 RAM
No overclocking is planned.
It’s not an excellent system, but I’m hoping the upgrade will make a noticeable difference.
I’m just hoping the power supply can handle it – I didn’t want to go for 1000W.
But Parts Picker warns about cables, so any advice would be appreciated.
Thanks very much.
The graphics cards include an adapter that connects 2x PCIe 8-pin to a 12VHPWR power source.
Hi
Darkbreeze
Thanks for the response. I was a bit taken aback by the information you provided, especially after asking the questions in my post.
Honestly, I didn’t do any research—it was just my limited understanding and an opinion based on what the title suggested on Amazon UK.
So, I just took the title at face value, thinking the 10 was more powerful.
Mea culpa.
Here are the two pages linked below:
https://www.amazon.co.uk/dp/B0883NZ...ol...Z8UFM7FWU9&psc=1&ref_=lv_ov_lig_dp_it
The i9-10900K with a base frequency of 3.70GHz
And the
i9-11900K (3.5 GHz / 5.3 GHz)
https://www.amazon.co.uk/dp/B08TX48...ol...Z8UFM7FWU9&psc=1&ref_=lv_ov_lig_dp_it
It looks like the i9-11900K is actually running at a lower frequency.
I didn’t dig into it much.
Also, I checked the cable, the card connections, and the power supply unit.
The main focus should be on the 850 running the setup—it’s the real concern.
Still, knowing the i9-11900K (3.5 GHz / 5.3 GHz) is a significantly better CPU at a similar price is helpful. 💎
Hey guys.
I just wanted to ask one more thing, even though I've searched a lot and tried to get a clear answer.
Thanks a lot for your great help and the advice you gave in this thread.
After reviewing all the details, I found out that the card shown in the video (only three seconds) comes with a 3 x 8 pin and a 1 x 16 pin 12VHPWR cable.
You can see it here: https://youtu.be/4aJYcZbciAc?t=51
But regarding the PSU, it only has one port with eight slots; the others are either ten or twelve.
For reference:
https://www.amazon.co.uk/dp/B083T9S...id=2RAZ8UFM7FWU9&ref_=lv_ov_lig_dp_it_im&th=1
I checked their official site and a part picker, both say it should work without needing extra cables.
On Google, when I asked the question, they told me to be quiet—just use a 11W Platinum 850W fully modular power supply with 6+2 PCIe slots.
As for the cables and connectors, here’s what I found:
Modular cables
✓ PCI-e 6+2 pins (for GPU)
4
PCI-e 6 pins (for GPU)
- SATA
11
PATA
4
The main question is: Will the PCIe 8 pin connectors fit in a 12-pin socket?
I didn’t want to open another thread, but I really appreciate any help you can give me. I tried to figure this out without asking again.
Best regards.
Your PSU features three PCIE 8 (6+2) pin cables, including one with two connectors. The PSU's ends contain 12 pins. Be Quiet! Straight Power 11 850W Review | bit-tech.net
