Intel Core i5-2400 (Clock speed at 100%) with AMD Radeon RX 470 (Clock speed at 100%) x1 will produce 14.1% of bottleneck. Everything over 10% is considered as bottleneck. - PC Builds
Graphic card and processor will work great together:
The 120w might not work with the 480w PSU in an Optiplex. After market PSU's often don't have enough power on certain rails. It's not just having enough power on the 12v rails, but also on the 3.3v/5v rails.
GTX 660 is also 10.2" long. In a normal Dell MT, like an Optiplex that's still a full size MT, like 390, 7010, 9010, etc., there's only 7" to work with without running into the RAM. 390/3010/3020 might be slightly less with slightly smaller MB.
GTX 660 is best suited for a gaming tower or in a Precision that's larger than a normal MT.
Dell 470 is either an oldie Precision (sff?) or a Vostro. Neither meets Win11 requirements.
140w GTX 660 needs at least a 450w PSU with 1x6-pin connector. Regular size PSU won't fit in an SFF. That doesn't mean there isn't the possibility of other options though. I also do not know that a GTX 660 would work in a Precision 470, notably too if it's SFF (small form factor) or DT (desktop) only.

Processor is too weak for this graphic card:
Intel Core i5-2400 (Clock speed at 100%) with AMD Radeon RX 470 (Clock speed at 100%) x1 will produce 14.1% of bottleneck. Everything over 10% is considered as bottleneck. - PC Builds
Graphic card and processor will work great together:
Intel Core i5-2400 (Clock speed at 90%) with NVIDIA GeForce GTX 1050 Ti (Clock speed at 90%) x1 will produce only 1.16% of bottleneck.
The GTX 1050 ti is a 75w card that will work with stock 265w PSU. Since the 265w PSU is nothing to brag about, your 480w PSU might be just fine.

What size is your 390? What exact CPU do you have? Knowing the CPU helps determine any potential bottleneck.

I have a dell optiplex 390 mini tower and I changed the power supply to a 480w and the gpu is

PC Builds recommends 8GB RAM to go with the GTX 1050 ti.

Thanks for answering. I meant "CPU," not GPU.
