    Arrow Seasonic Prime Ultra Titanium 750W Review

    At last our journey to find out what the entire line of Seasonic's Prime Ultra Titanium line is about has come to the final unit in the series, the 750 watt model. We already know the rest of the line is outstanding, but let's make sure this one performs like its siblings.

    Hey. At 0.5 amps the unit was 87.1% efficient. I don't believe I've seen a SB efficiency that high before.
    CPU: Core i7 8700k, HT enabled, all 6 cores OC'd to 4.8GHz, Vcore = 1.24v
    Heatsink: Noctua NH-D15 with one NF-A15 1500 RPM PWM fan
    Motherboard: Gigabyte Z370X Aorus Gaming 7
    RAM: 4x16GB (64GB) Corsair Vengeance LPX DDR4 RAM 16-18-18-36@3200MHz, Vdimm = 1.35v
    GPU: MSI GeForce GTX 1080 DirectX 12 with 8GB 256-Bit GDDR5X
    SSD1: Samsung 840 EVO 500GB TLC; SSD2: SAMSUNG 860 EVO 1TB 3-bit MLC
    HD: WD 500GB (old); Case: LIAN LI PC-7H Aluminum ATX Mid Tower
    PSU: Seasonic Platinum 660W

    Just wait until the new Intel requirements roll in.

    OK. I'll bite. What are the new Intel standby efficiency requirements?

    They don't want to change the connectors or make a new standard that's +12V only. They want to maintain backwards compatibility (though they did change -12V to "optional", thank goodness).

    But they have modified a number of timings, efficiency requirements, etc. all to get ready for CEC compliance and modern standby mode.

    This is old, but the newest public document: https://www.intel.com/content/www/us...e-changes.html

    About that, GI_Joe said that a feature motherboard, around 2020, won't be compatible with the current ATX 2.4 power supplies. That's still the case?

    Just like when C6 sleep state came out. You would just disable modern standby mode in the BIOS.
