    Default PSU recommendation 650w or 750w

    Hi all,
    First time writer, long time reader. I'm looking to upgrade/future proof my desktop and wanted to get the community's input on a Titanium or Platinum unit. Per the PSU Advise sticky, I've included the minimum requested necessary information (plus some):

    • CPU: i7 7700k (plan upgrade to AMD 3900X/3950X)
    • Memory: 2x 8GB DDR4 3200 sticks (CAS 16)
    • Motherboard: Asus Maximus Ranger VII (may change based on new CPU)
    • Graphics card: Current nVidia 1070 (plan upgrade to AMD 5700XT)
    • Drives: 1TB NVMe, 512GB SSD, 2x 7200rpm HDD, 1 Blu-ray, and 1 DVD/CD writer
    • Case: Corsair Carbide Air 540
    • Cooling: Corsair H100i Pro RGB and 3x Noctua NF-A14 fans
    • Overclocking: maybe...
    • Location: California, USA


    I plan to upgrade my GPU first (next two months), then the CPU around summer/early fall (waiting for prices to fall). Some of the PSU calculators place me at less than 650w, but recommend a 750w unit. Primary use is a workstation (video editing/GIS/modeling) about 32 hrs/week, with gaming ~ 10 hrs a week (Battlefield/COD). Due to the cost of electricity in my area, I'm looking to for a 80+ Platinum or Titanium unit. I currently have an EVGA 500 G2. Although I believe this should cover the system's requirements, I'd rather be safe, than sorry, especially with a bigger GPU. That being said, since there aren't any active reviews on the site any more, and I can't seem to find a "best of" titanium/plat/gold/etc. ranking list, and leave it to the hive mind for recommendations. Leaning towards Seasonic Prime/Focus or Corsair HXi units. Thoughts?

    Btw, big shout out to Jonny! Thanks for creating the site and getting all the great reviews out to the masses!

    A 550 G2?

    Anyway if it is what I think it is, then you will be fine. A 5700XT + 3950X build will consume around 400W or less, the PSU calculators are overestimating way too much in order to make money off the affiliate sales links.
