I'm piecing together a new PC using parts I've scavenged from different computers and I need some advice. Here's what I have so far: an ASUS Prime B760-PLUS motherboard, an Intel Core i9-12900K 3.2 GHz 16-Core Processor, an Nvidia RTX A4000 graphics card, 2x SAMSUNG 32GB DDR5 RAM, and a random 1TB SSD (which I plan to upgrade later).
Now I need to finalize the rest of my build without spending too much. Here's what I'm looking at:
- Case: Phanteks XT Pro
- CPU Cooler: Thermalright Peerless Assassin 120 SE
- Power Supply: I have a Liteon PA 3751-1 from an old work computer, but I'm not sure if it will work. Should I stick with this one or go for the MSI MAG A750GL PCIE5 instead?
Sorry if this sounds like a silly question; it's been about 15 years since I built my first computer and I'm feeling a bit out of touch!

Honestly, don't skimp on the power supply. It's one of the most crucial components for system stability and safety. I'd say go with the MSI MAG A750GL PCIE5 as it should be reliable enough for your setup. Better to invest a bit more in a good PSU than risk your whole build!

Do you think the MSI MAG A750GL PCIE5 is solid, or should I aim for something even more powerful?
