Fully Modular
Runs Relatively Cool (Compared to my 1200W 10 year old PSU)
Nealy Silent
All indication are that this is a high end efficient PSU made with quality components.
If you want to nit pick... braided/sleeved cables?
If you do a little research you will find there are 3 well known PSU manufacturers. This PSU is based off one of the best analog PSUs in production today and although there are likely some slight changes at the component level, per Antec specifications, there is no reason this PSU will not be just as good as the OEM platform that this PSU is based off of. I decided to go with this high end Antec since the prince, at the time of purchase, was reasonable and my prior Antec lasted 10+ years and it is still going. My power supply swap was or is a preventative measure.
This PSU provides more power than what I actually require but with some of the new GPU's on the horizon, that may need over 300 watts, I wanted to ensure I would not have any issue when it is time to upgrade.
High efficiency
Worked excellent for 5 months
Plenty of VGA cables
18AWG VGA cables
After 5 months the system started randomly shutting down when at full load. At most it used 1100w, which is well below the 1300w rating. The PSU was clearly at fault because the only way to get the machine to boot again was unplugging the power for 10 seconds then connecting it again.
I also know another person who used three of these units to power a 7x RTX 3090 rig, experienced the same random issues, replaced every single component, then replaced the power supplies and it was perfectly stable again.
Get a used EVGA 1600 for $160 or so instead of this piece of trouble.
