- Includes OVP, UVP, OCP, OPP, and SCP protections
- Compact form factor measuring 5.91 x 3.35 x 5.51 inches
Who it fits
Good fit for
This unit suits users building budget desktops for office work or light gaming. The 500W output handles systems with mid-range CPUs and single mid-tier GPUs. The included protections safeguard your components from voltage spikes or short circuits. If you need a simple, no-frills power source for a standard case, this fits well. It is ideal for first-time builders who prioritize basic stability over high efficiency or modular cables. The size ensures compatibility with most common chassis designs available today.
Who should skip it
You should look elsewhere if you plan to use high-end graphics cards or overclock your CPU. The 500W limit may not provide enough headroom for power-hungry components. The 80 Plus White rating is less efficient than Gold or Platinum units, leading to more heat and higher electricity costs under heavy load. If you need modular cables for cleaner builds, this unit lacks that feature. Users requiring silent operation or high efficiency for 24/7 uptime will find better options in higher-rated series.
Verdict: The EVGA 500 W1 offers solid basic protection and sufficient wattage for entry-level builds. It is a sensible choice for budget systems that do not demand high efficiency.
Key specs explained for EVGA 500 W1
Wattage: 500W
This value indicates the maximum continuous power the unit can deliver to your components. You can use this supply for entry-level systems with a mid-range CPU and a single graphics card. Higher-end gaming rigs may require more power. Check your component power draws to ensure this limit is sufficient for your specific build configuration.
Efficiency Rating: 80 Plus White
This certification confirms the power supply converts at least 80% of AC input power into DC output under typical loads. Less energy is wasted as heat compared to uncertified units. This results in slightly lower electricity costs and reduced thermal output inside your case. It is the entry-level standard for efficiency in modern builds.
OVP, UVP, OCP, OPP, SCP
These acronyms represent built-in safety mechanisms. Over Voltage Protection stops dangerous voltage spikes. Under Voltage Protection ensures stable power delivery. Over Current and Over Power protections prevent damage from excessive draw. Short Circuit Protection cuts power if a fault occurs. These features help protect your expensive computer components from electrical failures.
Dimensions: 5.91 x 3.35 x 5.51 inches
These measurements define the physical size of the power supply unit. You must verify these dimensions fit inside your chosen computer case. Standard ATX cases usually accommodate this size without issue. Smaller form factor cases may require specialized compact power supplies. Accurate measurement ensures proper airflow and installation clearance within your chassis.

It is not excessively light or heavy for its class.
The power supply features heavy-duty protections. These include over-voltage, under-voltage, over-current, over-power, and short-circuit protection. These safeguards help protect your components from electrical faults. According to the listing, the 80 Plus White certification ensures at least 80% efficiency under typical loads. This efficiency level is practical for entry-level builds. It reduces wasted energy as heat.
This model is part of a larger series. The brand offers variations in wattage, including 400W, 550W, and 700W options. Heights also vary, with some models reaching 5.5 inches. The 500W version you are reviewing uses the 3.35-inch height. This compact profile makes it suitable for tighter builds. The design focuses on basic functionality and protection. It does not include extra features like modular cables or displays. The build is straightforward and utilitarian.
Setup and everyday use guide
Installing the EVGA 500 W1 requires standard ATX case mounting. Its dimensions of 5.91 inches wide, 3.35 inches high, and 5.51 inches long fit most mid-tower and small form factor chassis. The unit weighs four pounds, making it manageable during cable routing. You connect the main 24-pin motherboard cable and your CPU power connectors. Since this is a non-modular unit, all cables are fixed. You must manage these wires carefully to maintain airflow. The 80 Plus White certification indicates at least 80% efficiency under typical loads. This means less wasted energy as heat during daily operation. The power supply includes heavy-duty protections to safeguard your components. Over voltage protection stops the output from exceeding safe limits. Under voltage protection ensures stable power delivery when demand fluctuates. Over current protection prevents damage if a component draws too much current. Over power protection cuts off power if the total load exceeds the 500W limit. Short circuit protection immediately shuts down the unit if a short is detected. These features operate automatically without user intervention. You do not need to configure software or drivers. The unit works with any standard desktop PC that fits the ATX size. It suits entry-level builds with mid-range CPUs and single graphics cards. Higher-end gaming systems may exceed the 500W capacity. Check your component power requirements before installation. The black color helps the unit blend into most cases. This is a plug-and-play solution for basic computing tasks.
Before you buy this PSU
You should verify your system’s total power draw before purchasing. The EVGA 500 W1 provides 500W of continuous power. This capacity suits entry-level builds with mid-range CPUs and single graphics cards. High-end gaming rigs may exceed this limit. Check your motherboard’s ATX 12V connectors. This unit requires standard ATX mounting. Its dimensions fit most mid-tower cases. You may need additional SATA cables if your storage devices lack direct connections. Keep the area around the fan clear for airflow. Dust accumulation can reduce efficiency over time. Clean the intake grill periodically. This model sits at the base of the EVGA lineup. It lacks the higher efficiency of Gold or Platinum units. It also offers less headroom than the 550W or 700W variants in the same series. If you plan to upgrade components later, consider a higher wattage option now. The 80 Plus White certification ensures basic efficiency. It does not offer the power savings of higher tiers. Review your existing UPS needs if you require backup power. This supply does not include battery backup capabilities.
Check before you buy
- Verify total system wattage stays below 500W.
- Confirm case supports standard ATX form factor.
- Check for required SATA power connectors.
- Ensure adequate case airflow for cooling.
