Question New PSU old PC

[Jay_Pee]

Hi all. My old psu's fan became noisy after 5 years. I took the safe, fast and hassle free route of just replacing it with a new one. My question is, do I need to have 2 seperate PCIE dongles to run a single GTX970? With my old psu I had no choice but to use 2 dongles because each only had 1 pcie+2 connectors. With my new one, a dongle has 1 pcie+2 and 1 pcie. My complete specs are below.

I5-4690K no overclock
Asus Z97
Corsair Vengeance 8gb (4x2)
One SSD 480gb
One HDD 2tb
One Optical Drive
EVGA GTX 970
Corsair CX 650M (New)

Thanks in advance!

JP

For a lower power card like a 970, a single dual connector cable is sufficient.

If you had a 980ti or titan (something with a 250w+ power limit) you might want to use two separate cables.

I had a bios modded 980ti Classified that I cranked up to 475W power limit, allowing it to draw 225W from each 8 pin, and I fed it with a single cable with dual connectors. The cable got warm to the touch but it still seemed alright (It was a heftier 16 gauge cable, not a thinner 18 gauge like some power supplies use).

In retrospect I probably should have swapped out for the two single cables in this use case.

You're fine.

Thank you for the peace of mind.
