I think the "not compatible with PCI-E" disclaimer has to do with the lack of an extra power cable for high-end PCIe video boards?Highly recommended for a budget build. ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Works well even if installed where it won't fit *by D***. on Reviewed in the United States on August 16, 2023* Used this "Coolmax I-500 500W ATX 12V V2.0 Power Supply (not compatible with PCI-E)" PSU to get an old Athlon II based PC quicly back up and running. Original PSU is SFX form factor and is one of those briefly manufacured around 2005 or so and having a very high current rating on the 3.3V and 5V rails. The now-failed original had ratings of 3.3V @ 22A and 5V @ 30A. A modern replacement SFX form factor PSU of suitable ratings seems to be unavailable - even the premium high power 800W or 1000W SFX PSU's don't supply anywhere near this much current on the 3.3V and 5V rails.This Coolmax PSU is ATX form factor (big) and should not and does not fit the subject PC's SFX form factor (small) case. It was therefore strapped to the side of the PC's case, and the case's cover left off. The Coolmax-provided cables were sufficiently long to reach the motherboard. This jury-rigged external PSU setup is working well. All output voltages are right on spec, and the Coolmax PSU runs cool, even though the Coolmax's 5V rail is rated at somewhat less current than that of the original PSU. The original PSU will be repaired and reinstalled as time permits, but until then, the old PC will chug on, powered by the externally-mounted Coolmax. ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Works great *by P***N on Reviewed in the United States on February 18, 2024* Works great as a replacement for my very old Orion HP585D, which is no longer available. Very happy with the price and compatibility. --- ## 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.pl/products/493467063-coolmax-500w-and-400w-atx-power-supply-bundle](https://www.desertcart.pl/products/493467063-coolmax-500w-and-400w-atx-power-supply-bundle) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-06-02*
