Requirements for PSU with numerous RGB devices
Requirements for PSU with numerous RGB devices
Hey everyone, I'm setting up a new rig and need some advice. My screen is 3440x1440p at 144Hz, and I’m not focused on hitting over 60 FPS in AAA titles. Right now my setup looks like this: CPU: I3-12100F, cooler: water cooler 240mm NO-RGB (just about Static, I know it’s a bit much), motherboard: H610M NO-RGB, RAM: two 8GB sticks at 3200MHz/CL16, GPU: MSI 3060 Ti (8+6pin connector, 220W TDP), power supply: Gigabyte GP-550B 550W, fans: four 120mm ARGB plus two 120mm NO-RGB. My main concern is the PSU—am I sure it can handle everything without overspending? I’m not sure if it’s enough just for this hardware, but I want to avoid extra costs. Also, I have several RGB peripherals and I’m worried about their power draw. The mouse pad, mouse, keyboard, headset, speakers—everything seems fine, but I’m not confident. I’ve had issues with my Razer setup lately: random USB drops, lights restarting unexpectedly, etc. It’s frustrating because I put so much effort into this and can’t enjoy it anymore. I hope someone has faced similar problems or can help me figure out the PSU issue. Thanks in advance for your time—I really appreciate it!
The 550w spec might be a bit tight; running under heavy load could strain it. I’d prefer a model in the 650-700 range for extra margin. You mentioned using an external powered hub with USB, which should work well—just ensure the connection isn’t dropping. If it fails, it’s likely an issue with the laptop itself rather than the USB ports. You can look up USB drivers on Dell’s site first, just in case.
RGB power consumption falls within 5 to 12 watts per foot. I won’t cover the rest, but as solado mentioned, 550 is on the higher side and I suggest 650 to 750. The USB issue might be more complex. The simplest fix is to use an unused USB port—plug one device in there. If that doesn’t work, disconnect the hub and connect either the keyboard or mouse. If it functions, reinsert the hub, attach a working device, and test each one separately while keeping the good ones connected. Try swapping cables with a known working device; this helps identify whether the problem is with the cable or the device itself. Keep repeating until you find the cause.
