B580 with 450w
Hi everyone,
I’m planning to upgrade my old RX 570 8GB to a new Intel Arc B580. I’m a bit concerned about my current Power Supply and I would like your expert opinion.
My Specs:
CPU: Ryzen 5 5600 (Stock cooler)
GPU: Intel Arc B580 (planning to buy)
PSU: Enermax MAXPRO II 500W (EMP500AGT-C) - 80 PLUS 230V EU
Technical details of my PSU:
It’s a 500W unit with a single +12V rail rated at 38A, providing 456W on the main rail. It has two 6+2 pin PCIe connectors on a single cable.
My doubts:
Intel recommends a 600W PSU for the B580, but my total system draw should be around 350-370W. Is the 456W on the +12V rail enough to handle the spikes?
I’ve heard the B580 software readings show ~120W, but the actual TBP is closer to 190W.
Is it safe to run this card on a 500W "entry-level" PSU considering I also have 3 drives and 4 fans?
Thanks in advance for the help!
