I recently purchased an Asus RTX 5070 for a future build, but I'm wondering if I can also use it in my current system. Here are my specifications:
- Motherboard: Gigabyte Aorus Master Z390
- CPU: Intel i9-9900k
Since my Z390 is only PCIe 3.0, will the GPU still work? Also, I'm using an older Corsair RM850x power supply from 2018, and I've heard I might need a separate PCIe cable. I was recommended a 12VHPWR StealthSense 16-pin to dual 8-pin cable from Corsair. Is this the right choice?

Yes, you can use the RTX 5070 in your current setup without any issues!
Yes, you can absolutely use the RTX 5070 with your PCIe 3.0 motherboard, but just keep in mind that you might not get the full performance out of it compared to using it on a PCIe 5.0 setup. It’ll work, just at reduced capabilities.
For the cable, you'll want a Type 4 PCIe 6+2 connector from Corsair, just avoid the pigtail one. The RTX 5070 should come with a PCIe adapter in the box, so you can use two standard 8-pin PCIe cables with it. Just a heads up, combining your CPU with the new GPU might lead to some stuttering in demand-heavy games, so keep an eye on that.
The RTX 5070 will work with your setup. It typically includes an adapter for your power supply. If you want to get a cable for better aesthetics, you can look for a 12V-2X6 cable, but it’s not strictly necessary. That said, this might be a good time to consider selling your CPU and motherboard, as they have decent resale value. You could potentially upgrade to newer components at little to no cost!
Definitely! PCIe is backward compatible, so your new GPU will work just fine with your existing motherboard. The RTX 5070 should even come with an adapter for the power cables, so no worries there!
That’s right! You could sell your i9-9900K and Z390 for a good price and get something more powerful like an i5-12600KF. Might be worth it if you're looking for better performance overall.
