He owns one of those Windows 7, 64-bit, Lenova computers that looks like a toaster oven. I took the old power supply out and put this new one in and he's back in business. It was all just that simple and he's tickled pink because he thought he was going to have to buy a new computer. ### ⭐ 1.0 out of 5 stars One of two units ordered was bad out of box *by N***S on Reviewed in the United States on June 2, 2018* One of two units ordered was bad out of box. Unfortunately, I had the unit for over two months before even opening the box. This is seriously unimpressive. I run a technology related company and always order extra hardware just to keep a part I will likely need on my shelf. Don't count on hardware from this company to actually work once you pull it off your shelf. ### ⭐⭐ 2.0 out of 5 stars Rattles and roars like bearings are worn out *by D***E on Reviewed in the United States on January 15, 2016* Have had for about 3 months and fan is already going out. Rattles and roars like bearings are worn out already --- ## 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.pt/products/20085191-slimline-power-supply-upgrade-for-sff-desktop-computer-fits-compaq](https://www.desertcart.pt/products/20085191-slimline-power-supply-upgrade-for-sff-desktop-computer-fits-compaq) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-04-24*
