Review: This is a great PSU. It is a bit noisy if you are anal like me and others on this review page. If you'd like to void the warranty and put a quieter fan in this PSU my suggestion after trying the noctua route is to not use noctua (the fans people are recommending on this review page are not rated for this psu in terms of cooling efficiency and in my case the fan wouldn't even turn on unless I hooked it into my fan header on my motherboard even though its 12v in the psu and on the noctua fan. A more proper recommendation and expert advice would be to purchase Delta AFB0412HB 12V DC 0.16A Fan 40mm x 40mm x 15mm from ebay for 6 dollars. Be sure to check the polarity of the 2 pin/wire for this fan to ensure it matches the existing scheme/configuration. I believe its reversed but like I said, check for yourself. But Delta AFB0412HB 12V DC 0.16A Fan 40mm x 40mm x 15mm is a much better option than the Noctua. Don't waste your money on the noctua 40x10mm as not only is it too small and would require duct tape to cover the gap on the outside of the psu after its installed, its not even strong enough to push air in an efficient manner. Anyhow I wish you all good luck in your DIY this psu. For those not that are not ANAL like me, the noise is really not that bad. But I'll let you be the judge as I have tinnitus so I hear ringing in my ears anyway. Review: Solid PSU. Fits nicely into a Watchguard M470 firewall that runs OpnSense. Do note that the fan when it kicks in is a bit louder than desired, and there are several guides on how to change out the fan. Note: Those guides will void warranty, and heed the advice given - don't use a Noctua fan, it doesn't shift enough air. ## Features - Support Standard flex ATX Form Factor - High efficiency with 80 PLUS Gold certification - 350W Continuous power output at 40℃ operating temperature rated for 24/7 operation - Support PCIe 6pin connector.Active PFC.Small form Factor PSU - International products have separate terms, are sold from abroad and may differ from local products, including fit, age ratings, and language of product, labeling or instructions. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07QGMX5DW | | Are Batteries Included | No | | Brand | SilverStone | | Customer Reviews | 4.3 4.3 out of 5 stars (311) | | Date First Available | 23 April 2019 | | Form Factor | Flex ATX | | Guaranteed software updates until | unknown | | Item Weight | 960 g | | Item model number | SST-FX350-G-USA | | Manufacturer | SilverStone Technology | | Product Dimensions | 8.15 x 4.04 x 15.01 cm; 960 g | | Series | ATX Power Supply | | Wattage | 350 watts | ## Product Details - **Brand:** SilverStone - **Connector type:** atx,pcie - **Cooling method:** Air - **Form factor:** Flex ATX - **Item dimensions L x W x H:** 8.2 x 4 x 15 centimetres - **Item weight:** 0.96 Kilograms - **Model name:** ATX Power Supply - **Output wattage:** 350 - **Wattage:** 350 watts ## Images ![SilverStone Technology 350 Watt Flex ATX Power Supply with Fixed Cables and 80 Plus Gold with 6Pin PCIe Connector SST-FX350-G-USA - Image 1](https://m.media-amazon.com/images/I/7149U9NFN5L.jpg) ![SilverStone Technology 350 Watt Flex ATX Power Supply with Fixed Cables and 80 Plus Gold with 6Pin PCIe Connector SST-FX350-G-USA - Image 2](https://m.media-amazon.com/images/I/71ZW1GdFb2L.jpg) ![SilverStone Technology 350 Watt Flex ATX Power Supply with Fixed Cables and 80 Plus Gold with 6Pin PCIe Connector SST-FX350-G-USA - Image 3](https://m.media-amazon.com/images/I/71tIHAhvr9L.jpg) ![SilverStone Technology 350 Watt Flex ATX Power Supply with Fixed Cables and 80 Plus Gold with 6Pin PCIe Connector SST-FX350-G-USA - Image 4](https://m.media-amazon.com/images/I/71+-LlV9Q8L.jpg) ![SilverStone Technology 350 Watt Flex ATX Power Supply with Fixed Cables and 80 Plus Gold with 6Pin PCIe Connector SST-FX350-G-USA - Image 5](https://m.media-amazon.com/images/I/71offt4xL4L.jpg) ## Questions & Answers **Q: Does this have a 6 to 8 pin connector for a gpu included?** A: Here are all of the connectors for this power supply: 1 x 24 / 20-Pin motherboard connector（350mm） 1 x 2-Pin connector (300mm)* 1 x 8 / 4-Pin EPS / ATX 12V connector（450mm） 1 x 6-Pin PCIe connector（350mm） 3 x SATA connector（350mm / 150mm / 150mm） 2 x 4-Pin Peripheral connector（350mm / 150mm） 1 x 4-Pin Floppy adapter connector（350mm / 150mm / 150mm） Hope that answers your question. **Q: Is it compatible with msi nightblade mib090?** A: MSI does not share the size nor the form factor of PSU used on their product page so you may need to double check with MSI directly for dimensions of the PSU inside the Nightblade MIB 090 with that of FX350-G, which is a FlexATX power supply. All specifications of the FX350-G are available on its product page: https://www.silverstonetek.com/en/product/info/power-supplies/FX350-G/ **Q: What is the cable length of the 24pin connection to the motherboard?** A: The length of the included 24pin cable is 350mm (13.8 inches) long. For more detailed information on this power supply, please check out its product page on our website: https://www.silverstonetek.com/en/product/info/power-supplies/FX350-G/ **Q: Will this fit in a evga hadron mini itx case?** A: More than likely no, but check the specs of the EVGA chassis manual. I’m sure you’ll find it on the EVGA site. EVGA is a great company that makes a solid product ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by J***K on 3 January 2024* This is a great PSU.

Es mas para builds ultra compactas y en eso cumple su funcion muy bien. ## Frequently Bought Together - SilverStone Technology 350 Watt Flex ATX Power Supply with Fixed Cables and 80 Plus Gold with 6Pin PCIe Connector SST-FX350-G-USA, Black（Lead-Free Paint） - Gigabyte A520I AC (AMD Ryzen AM4/Mini-ITX/Direct 6 Phases Digital PWM with 55A DrMOS/Gaming GbE LAN/Intel WiFi+Bluetooth/NVMe PCIe 3.0 x4 M.2/3 Display Interfaces/Q-Flash Plus/Motherboard) --- ## 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.co.uk/products/227412250-silverstone-technology-350-watt-flex-atx-power-supply-with-fixed](https://www.desertcart.co.uk/products/227412250-silverstone-technology-350-watt-flex-atx-power-supply-with-fixed) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-06-08*
