Graphic Card Upgrade Question

[Rovylern]

Greetings programs. I’m trying to upgrade the 2060 RTX that came with my Omen 880-160 to a 4070 SUPER. My problem is that the 4070 is a beast of a card and blocks the 6-pin GFX_PWR1 connector on the motherboard.  The 4070 came with a 16-pin 12VHPWR to 8-pin PCIe power adapter cable (2x8-pins in to 16-pin out). Do I need to worry about the GFX_PWR1 pins, or will plugging two power tails (P9 and P10) into the adapter and leaving GFX_PWR1 open be sufficient?

Thank you in advance for any assistance.

@Rovylern,

Welcome to our HP Community forum!

Your OMEN by HP Desktop PC - 880-160se (2TB61AV) as fitted with the Tampa2 motherboard (SSID: 8437) has a 6-pin "GFX_PWR1" power connector which is designed to provide additional power for PCIe expansion cards, primarily graphics cards (GPUs). 

However, your 750-watt power supply's P9 and P10 graphics card 8-pin PCIe power cables are all that is needed to power your GTX 4070.

In other words, leaving the "GFX_PWR1" power connector unplugged is perfectly A-OK.
