Question HELP PSU

[N aofumi]

Hi, I am not that knowledgeable in PC components, this is my current build:

Intel 14th Gen i5-14600K
ASUS Nvidia Dual 4060 8GB GPU
32GB DDR5 6000Mhz RAM
1TB m.2 SSD
Coolermaster 850W MWE V2 80+ gold PSU.

I am planning to upgrade to an NVIDIA 4070 Super or 4070Ti Super GPU. Unfortunately, I only have an ATX 2.4 PSU which doesn't have a native 12vhpwr port.
Would I still be able to use my current PSU with the new cards? Will I run into any issues?

Thank you in advance.

Welcome to the forums, newcomer!

The graphics card should come with a 12VHPWR adapter, so long as you have a 2x8pin or 3x8pin PCIE connectors stemming off your PSU, you should be good to go. For the sake of relevance, which AIB partner card are you looking into for the purchase?

Thank you for the answer. I might go with Gigabyte since they tend to be cheaper compared to other brands.

With regards to the adapter, would that be safe, I mean it won't cause the connectors to melt?

If all the connectors are seated firmly, it'll probably be safe. When the new 12VHPWR power connector design appeared, there were horror stories with melted connectors on RTX 3090 and 4090 cards. However, the majority of users had no problems. You only get to hear of the failures.

At first the manufacturers blamed the users for not seating the connectors firmly enough. Then they redesigned the connector. Problems still occur, but less frequently.

People experienced melting connector problems on GPUs before the 12VHPWR design appeared, but they received less attention in the press, partly because the currents drawn were lower than those demanded by a 3090/4090, so overheating damage was less severe.

You are wise to be cautious, but you can reduce the likelihood of disaster by taking a few precautions. Read up on the subject. Check for reports on problems associated with the adapter (if supplied) for your card. Watch a few videos.

You've got to power the card somehow. Periodically check for signs of overheating.
