I'm planning to upgrade my aging prebuilt PC, starting with a new power supply unit (PSU). Currently, I have a Corsair 650W CV, but I want to move up to a solid, reliable 1000W PSU for better performance. Key factors for me are build quality, efficiency (I've heard there's an optimal efficiency range), and low noise levels. I'm using my PC for video editing, rendering, and gaming. I live in the UK, and my budget is £150. Any recommendations would be greatly appreciated!

You can also visit website like PCPartPicker to filter and sort PSUs by wattage and efficiency ratings. Look for Gold or Platinum rated models to get the best performance. Just keep in mind that some models may have issues like coil whine, so do a bit of research before buying.
If you're overwhelmed searching for PSUs, check out the SPL tier list. It grades units, so picking an A grade PSU at your desired wattage will make things easier.
Great tip! I'll definitely look into that to narrow down my options.
I usually go with Seasonic. I've had great experiences with their PSUs, plus they offer a solid warranty. Very dependable.
I’d recommend checking into smaller form factor PSUs if you plan on more upgrades later. Corsair SF850 is good, but keep in mind that Seasonic’s SFX models might not be up-to-date with the latest PCI standards.
Good point! I’ll have to think about whether I really need 1000W or if something smaller could work.
For your needs, I'd suggest considering the Corsair RM1000x. It's well-regarded in terms of reliability and efficiency. Plus, it should have the power you need for future upgrades like your GPU.
Thanks for the recommendation! I appreciate it.

Thanks for all these resources! I'm trying to learn about things like ATX standards and power spikes, so any info is helpful.
