So you should have two separate cables from the power supply connecting to the two peripheral (molex) connectors on RM43-320-RS's backplane directly. Do not connect both connectors on the backplane with just one cable! **Q: Do you need to plug in both 4pin molex connectors per backplane?** A: Yes you do. **Q: What CPU cooler are you using for this? Does the NH-D12 fit?** A: The RM43-320-RS can fit CPU cooler up to 148mm in height. According to Noctua's product page, the NH-D12L is 145mm tall so yes, it will fit in the case. **Q: I see the that the chassis supports up to 148mm clearance for cpu cooler, can a 151mm cooler be made to fit in here?** A: Probably not, we set the 148mm limit because that's all the room available for it. ## Frequently Bought Together - SilverStone Technology RM43-320-RS 4U 20-Bay 2.5" / 3.5" HDD/SSD rackmount Storage Server Chassis with Mini-SAS HD SFF-8643 12 Gb/s Interface, SST-RM43-320-RS - LSI 9300-16i 16-Port 12Gb/s SAS Controller HBA Card with P16 IT Mode for ZFS TrueNAS unRAID - OIKWAN Internal Mini SAS to Mini SAS Cable, SFF-8643 to SFF-8643, Compatible with RAID or PCI Express Controller (1.6FT/0.5M) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.in/products/413622880-technology-rm43-320-rs-4u-20-bay-2-5-3](https://www.desertcart.in/products/413622880-technology-rm43-320-rs-4u-20-bay-2-5-3) --- *Product available on Desertcart India* *Store origin: IN* *Last updated: 2026-09-03*
