And I did try several adapters as well to know avail. ### ⭐⭐ Internal cable too short *by J***A on September 6, 2025* The power supply is functioning properly, but the internal cable connecting it to the motherboard is too short to reach the motherboard connector ### ⭐⭐⭐ Great seller response, but 4+4 cable length too short *by A***R on February 14, 2025* The seller TFGJ deserves 5 stars ***** for being very responsive and personable. This TFX Power Supply 400W power supply might work fine for some builds, but sadly I have to return it unused because its 4+4 cable, at 11", is just too short to reach the outlet on a MicroATX board. The old power supply's 4+4 cable was 17", so major difference. If your system board is smaller than a MicroATX or the outlets are closer to the PS, this PS might be fine for you. The 3 stars for this review are a compromise between the 5 stars for the seller and 1 star for the short cables preventing use. Someone who has been able to use this PS may get great performance out of it and rate it higher. --- ## 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.ec/products/645339750-tfx-power-supply-400w-psu-fixed-cable-stand-full-voltage](https://www.desertcart.ec/products/645339750-tfx-power-supply-400w-psu-fixed-cable-stand-full-voltage) --- *Product available on Desertcart Ecuador* *Store origin: EC* *Last updated: 2026-04-22*
