I upgraded my PC with a 700W 80 Plus Gold power supply and an RTX 2070 Super, but I'm not confident installing either component myself. Local computer shops quoted me around $120 for the work, which feels expensive since it seems like I'm only replacing part of the system. Is that a normal labor charge, or should I try doing it myself? My biggest concern is connecting everything correctly, especially the case fans and motherboard cables.

The main risks are using the wrong modular cables, forgetting a motherboard or graphics-card power connection, or leaving a cable loose. Work slowly and check the motherboard and PSU manuals before powering on. If you’re still uncomfortable after reviewing the steps, paying for installation is essentially paying for confidence and troubleshooting if something doesn’t work.
The graphics card is usually very straightforward: shut the computer down, unplug it, remove the old card, install the new one, and connect the required PCIe power cable. The power supply is the part that takes more care because every cable must be replaced with the cables that came with the new PSU. Never reuse modular cables from the old power supply.
The price is mostly for labor and cable management. Replacing a modular power supply means disconnecting every old power cable, removing the unit, installing the new one, and routing all the replacement cables. An hour of shop labor at that rate isn’t especially unusual, though it can still feel expensive for a simple upgrade.
You could reasonably do this yourself if you’re comfortable following a detailed PC-building guide. Take clear photos before disconnecting anything, label cables if needed, and make sure the computer is fully unplugged before working inside it. The fans may connect directly to the motherboard, a fan hub, or the power supply, so you might not need to touch them at all unless their cables are connected to the old PSU.
