CORSAIR RM850x ATX 3.1 PCIe 5.1 Ready Fully Modular 850W Power Supply
$139.99 is its usual price.
The middle price across the 20 days we have watched it, counting the days a limited-time deal was running, was $139.99. Today's price is also the lowest we have recorded, so our record has nothing lower to wait for — but a price this close to the usual one is not a discount, whatever former price is printed beside it.
The lowest since September 21, when it cost $139.99.
This describes the prices we recorded. It is not a forecast of where this one goes next.
