FlyingTexan Posted February 16, 2023 Share Posted February 16, 2023 I have a NZXT 750w gold that's great. But I'm stepping up my system going with two drive bays which would give me a total capacity of 24 drives. I'm wondering how many drives I can really run off my PSU in this system. Config: intel 11600k arc a380 (when supported) 4x 16GB DDR4 LSI 9300-16i If the new arrivals cure my potential power cable issues where I'm not having to throw away two drives, I'll be at 19 total drives. Is 750w enought? Quote Link to comment
FlyingTexan Posted February 16, 2023 Author Share Posted February 16, 2023 well kept googling and found a post on reddit showing https://outervision.com/power-supply-calculator. Says 656watts for me. How reliable does that feel? Quote Link to comment

Says 656watts for me. How reliable does that feel? A hard drive will typically consume 7-10W during read/write so no issues there. This issue is spin up current which can be 30-35W per drive for a couple of seconds so 19 drives could peak at 665W + base system of 50-100W which is the max of the PSU. Most PSU can take a short burst of high current and the actual value would depend on the the specifics of the drives used. Perhaps less with 5400 drives than 7200. Quote Link to comment
