Seems like a good deal to me. Competing outlets are selling this unit at $225 to $250, with Amazon's price at $195. This is an A-Tier ranked ATX 3.0 PSU according to the PSU tier list https://cultists.network/140/psu-tier-list/
Surcharges: 1.2% Card & PayPal, 2% AmEx. Free shipping excludes WA, NT & remote areas.
I just ordered, hope this helps someone else building a PC.
Black version has been at $149 for weeks. White version has only just increased in price lately.
