[SOLVED] PSU Recommendation


Mar 8, 2007
Hi Community!

I just wanted to pass along a build that I'm currently working on, and I wanted to make sure the PSU I selected is up to snuff. My build is below, but first a few details :
  • Parts are already in hand, so nothing is going to change in it outside of the PSU. I'm not asking for a critique of my entire build, you can if you want, but honestly it's the PSU that I want to be focused on
  • The actual memory is Kingston Fury Renegade 4x8 GB, but the only available 4x8 GB at 3600 speed on PCPartPicker was the HyperX Predator. Hopefully power needs are close enough
  • This rig will be used for gaming (1080-1440p) and productivity (a little coding, mostly Office applications) purposes; minimal video or music editing (once in a blue moon)
  • This computer will rarely be turned off, though it won't be used 24/7; regular use of 10 hours daily is expected
  • I don't expect to overclock anything; I like my machines to last forever (as the technology allows it)
That said, here's the build:

CPU: Intel Core i7-12700KF 3.6 GHz 12-Core Processor
CPU Cooler: Deepcool CASTLE 240EX 64.4 CFM Liquid CPU Cooler
Motherboard: Asus PRIME Z690-P D4 ATX LGA1700 Motherboard
Memory: Kingston HyperX Predator RGB 32 GB (4 x 8 GB) DDR4-3600 CL17 Memory
Storage: Samsung 980 Pro 500 GB M.2-2280 NVME Solid State Drive
Samsung 980 Pro 1 TB M.2-2280 NVME Solid State Drive
Western Digital BLACK SERIES 2 TB 3.5" 7200RPM Internal Hard Drive
Video Card: MSI GeForce RTX 3080 10GB LHR 10 GB VENTUS 3X PLUS OC Video Card
Case: Cooler Master Silencio S600 ATX Mid Tower Case
Power Supply: Corsair RMx (2021) 750 W 80+ Gold Certified Fully Modular ATX Power Supply

Based on PCPartPicker, my power needs are coming in at 664W, which concerns me a bit because that's already 88% of the PSU capacity (granted at full load). That's the part that makes me nervous, and just wondering if I'm worrying too much or not.

So: Should I opt for a larger PSU, or am I okay with the one I currently have on hand? Thanks in advance for any and all suggestions/recommendations/replies.
