This article covers EVGA 500W 80PLUS Certified ATX12V.

Overview

The EVGA 100-W1-0500-KR is a 500W ATX power supply with 80PLUS Certified efficiency, designed for budget-conscious builders. It delivers reliable power for entry-level gaming PCs and office desktops, with a single +12V rail rated at 40A (480W). This unit features a 120mm sleeve-bearing fan for cooling, and supports both ATX12V and EPS12V standards, making it compatible with a wide range of motherboards. The non-modular cable design keeps costs low, but requires careful cable management in smaller cases. With a 3-year warranty (subject to the seller's policy for imported units), the EVGA 100-W1-0500-KR is a straightforward choice for anyone building a simple, budget-friendly PC without the need for high efficiency or modular cabling.

Compatibility Guide

Form Factor: Standard ATX (150×140×86mm) fits most ATX, MicroATX, and Mini-ITX cases with sufficient space. Connectors: ATX 20+4-pin main, EPS 4+4-pin CPU, two PCIe 6+2-pin (for GPU), four SATA, and three peripheral 4-pin connectors. Motherboard Compatibility: Works with any ATX, MicroATX, or Mini-ITX motherboard. However, high-end boards requiring dual EPS 8-pin connectors are not supported. GPU Support: Can power GPUs up to about 200W TDP (e.g., GeForce RTX 3060, Radeon RX 6600). Not recommended for GPUs exceeding 300W. * Total System Load: Keep the combined CPU+GPU load under 350W to avoid overloading the 500W capacity during peak draws.

Product Info

The EVGA 100-W1-0500-KR was first released in 2014 and has remained a popular budget option. It carries 80PLUS Certified efficiency (≥82% at 50% load, 115VAC) and a single +12V rail design. The unit uses a 120mm sleeve-bearing fan, which is cost-effective but not the quietest under load. Market positioning is firmly entry-level. It lacks modular cables, 80PLUS Gold or higher certification, and premium fan bearings. However, its low price makes it ideal for first-time builders and those on a tight budget. The warranty is 3 years, but note that imported units may not include manufacturer warranty in all regions.

Best Use Cases

Budget First-Time Builders — Pair with an entry-level CPU (Ryzen 5 / Core i5) and a GPU like the RTX 3050 or RX 6600. The 500W capacity is sufficient for 1080p gaming without breaking the bank. Secondary PC or File Server — For low-power CPUs with integrated graphics, the 500W unit provides more than enough headroom at a very low cost. Emergency Replacement — If your existing PSU fails, this unit is affordable and widely available, making it a quick temporary fix. Who should NOT buy: Users planning high-end gaming (RTX 4070 or above, Core i9/Ryzen 9). Enthusiasts who want modular cabling or high efficiency (80PLUS Gold or better). Builders who prioritize near-silent operation (the sleeve-bearing fan can be audible under load).

Things to Consider

This power supply is over a decade old in design. It does not support ATX 3.0 or the 12VHPWR connector, so it's not suitable for the latest high-end GPUs. The sleeve-bearing fan is prone to wear over time, and noise may increase after a few years of heavy use. Non-modular cables mean you'll have to manage unused connectors inside the case. This can be challenging in compact builds. The 80PLUS Certified tier is the lowest efficiency level, so electricity costs will be slightly higher than with a Bronze or Gold unit. If you are building a system that will run 24/7 under sustained load, consider investing in a more efficient and durable PSU. For occasional use or a secondary PC, the EVGA 100-W1-0500-KR is a perfectly adequate choice. ## FAQ
Q: Can this PSU power a GeForce RTX 4060? A: Yes, the RTX 4060 has a TDP of 115W and requires a 300W PSU. The EVGA 500W unit provides enough power, as long as the CPU load is moderate. Use one of the PCIe 6+2-pin cables. Q: Are the cables modular? A: No, this is a non-modular PSU. All cables are permanently attached. You will need to tuck unused cables inside the case. If you prefer a clean build, look for a semi-modular or fully modular unit. Q: Is this unit safe for a PC that stays on 24/7? A: It can run 24/7, but the sleeve-bearing fan has a shorter lifespan than a ball-bearing or fluid-dynamic bearing fan. If the PSU is under constant load, the fan may wear out faster. For always-on servers, a higher-quality PSU is recommended.
