The MSI MAG A500DN II is a 500W ATX12V power supply for budget and mainstream desktop PCs using moderate-power CPUs and graphics cards. It includes a 120 mm fan, active PFC, a single +12V rail, two 6+2-pin PCIe connectors, and built-in protections for everyday gaming and general-purpose builds.
Recommended For
- Budget ATX desktop builders using integrated graphics or a low-power graphics card, where total system power demand stays comfortably below the 500W rating.
- Entry-level 1080p gaming PC builders pairing a mainstream CPU with a modest graphics card and no plans for a high-power GPU upgrade.
- Cost-sensitive users replacing an older ATX power supply in a home, school, office, or refurbished desktop, provided standard non-modular cabling is acceptable.
- DIY builders who want a basic 500W ATX unit with flat cables, active PFC, a compact 140mm chassis, and standard protection features rather than premium PSU features.
Real-World Use Scenarios
- Building a budget home or office PC with integrated graphics or a low-power graphics card: the MAG A500DN II should provide enough capacity for everyday browsing, office software, streaming, and light creative work without requiring a higher-wattage PSU.
- Assembling an entry-level gaming PC with a modest single graphics card: the two PCIe power connectors and 500W capacity support common budget gaming builds, although users should verify the GPU maker’s recommended PSU rating before purchase.
- Replacing an older or failed power supply in a standard ATX desktop: the familiar 24-pin motherboard, 4+4-pin CPU, PCIe, SATA, and peripheral connections make it suitable for conventional non-modular PC upgrades, but cable routing requires planning because unused cables remain attached.
- Installing the PSU in a compact or space-constrained ATX case: the short 140 mm body and flat black cables can make physical installation and basic cable routing easier, while the non-modular design may still add cable clutter behind the motherboard tray.
- Running a typical desktop or light gaming workload for long sessions: the active-PFC design, 120 mm fan, and built-in protection features are intended to maintain normal operation and cooling, but this model is better matched to moderate systems than high-end GPUs, heavy overclocking, or major future upgrades.
Reference Q&A
Q: Should I buy the MSI MAG A500DN II or the MSI MAG A550BN?
A: Choose the MAG A550BN for a gaming PC or an upgrade-focused build. It provides 550W, 80 PLUS Bronze efficiency, DC-to-DC power conversion, and a 5-year warranty. Choose the MAG A500DN II when the lower purchase cost is the priority and the system uses a modest CPU and graphics card. The A500DN II provides 500W, 80 PLUS Standard efficiency, six SATA connectors, and a 3-year warranty.
Q: Is the MSI MAG A500DN II better than the Corsair CX550?
A: The Corsair CX550 is the stronger choice when efficiency, warranty coverage, and a little extra capacity matter. It offers 550W, 80 PLUS Bronze efficiency, a 5-year warranty, and a 528W 12V output. The MAG A500DN II is a practical alternative for a lower-cost build and provides six SATA connectors compared with the CX550’s three SATA connectors. Both models are non-modular ATX power supplies with dual 6+2-pin PCIe connections.
Q: Should I get the MSI MAG A500DN II or spend more on the MAG A650BN?
A: Choose the MAG A650BN for a higher-power gaming system or a build that may receive a stronger graphics card later. It provides 650W, 80 PLUS Bronze efficiency, DC-to-DC design, and 648W available on the 12V rail while keeping the same 140mm-long ATX form factor. Choose the MAG A500DN II for a basic system whose estimated power use comfortably fits within 500W and where minimizing cost is more important than upgrade capacity.
Q: What is different between the MSI MAG A500DN II and the original MAG A500DN?
A: The MAG A500DN II is the better fit when you need broader input-voltage support and more storage-device connections. MSI lists the A500DN II with 100–240V input, six SATA connectors, sleeve-bearing cooling, and additional protection specifications including OTP and UVP. The original A500DN is listed with 110–240V input, five SATA connectors, a hydro-bearing fan, and four primary protection functions. Both models are 500W, non-modular, 80 PLUS Standard ATX power supplies with two 6+2-pin PCIe connectors.
Q: Is the MSI MAG A500DN II suitable for a newer graphics card, or should I buy an ATX 3.1 PSU?
A: Choose an ATX 3.1 model such as the MSI MAG A650BN PCIE5 III for a newer graphics card or a planned GPU upgrade. The A650BN PCIE5 III provides 650W, a native 12V-2x6 connector rated for up to 300W, PCIe 5.1 support, and two EPS connectors. The MAG A500DN II is better suited to entry-level or midrange systems that use standard 6+2-pin PCIe power connections and have a confirmed power requirement below 500W.
Q: Is 500W enough for a gaming PC or graphics card?
A: It can be suitable for an entry-level or mid-range gaming PC when the complete system stays within the 500W capacity and the graphics card recommends 500W or less. The PSU includes two 6+2-pin PCIe connectors, but high-power GPUs, overclocked systems, and systems with substantial future upgrades may require a higher-wattage PSU.
Q: Is this power supply compatible with a standard ATX motherboard?
A: Yes. The MSI MAG A500DN II is an ATX12V power supply with a 20+4-pin motherboard connector and a 4+4-pin CPU connector, covering the common power connections used by standard ATX systems. Check the case clearance and confirm that the computer does not use proprietary motherboard or power connectors.
Q: Is the MSI MAG A500DN II modular, and are the cables included?
A: It is non-modular, so the power cables are permanently attached rather than detachable. The listed connections include one 24-pin ATX cable, one 4+4-pin CPU cable, two 6+2-pin PCIe cables, six SATA connectors, and two peripheral connectors. Non-modular cabling is functional but can create more cable clutter than a modular design.
Q: Is this PSU suitable for everyday gaming and general desktop use?
A: It is intended for standard desktop and moderate gaming systems that require up to 500W. Its 120 mm fan, active PFC, single 12V rail, and listed protection features support normal operation, while the 80 PLUS Standard rating indicates up to 80% efficiency. It is less suitable for high-end GPUs, heavily overclocked systems, or builds planned for major power-demand increases.
Q: Can it power a graphics card that needs an 8-pin PCIe connector?
A: Yes. Each 6+2-pin PCIe connector can serve a graphics card that uses a standard 8-pin PCIe power input. Confirm the graphics card's recommended PSU wattage and connector requirements before installation; having the connector available does not by itself guarantee that the 500W capacity is sufficient.
Q: Is the MSI MAG A500DN II enough for a budget gaming PC?
A: It can be suitable for a modest gaming system with a midrange CPU and GPU, such as Ryzen 5/RX 6600-class hardware, provided the system’s total power demand stays comfortably below 500 W. It is less suitable for high-power GPUs or systems planned for major upgrades.
Q: Is the MSI MAG A500DN II a good choice for an RTX 5060 build?
A: The 500 W capacity and two 6+2-pin PCIe connectors can support a low-to-midrange RTX 5060 system when paired with an efficient processor and other components. However, community discussion suggests choosing a higher-quality 550–650 W unit if buying new or planning future upgrades.
Q: What are the main trade-offs of buying the MSI MAG A500DN II?
A: Its advantages are the low-capacity 500 W format, active PFC, single 12 V rail, and basic protection features. The trade-offs are 80 PLUS Standard efficiency, a non-modular design, limited 500 W headroom, and community concerns about its entry-level quality and limited independent testing.
Q: Should I buy the MSI MAG A500DN II, or choose a better PSU?
A: Choose the A500DN II mainly when the system is budget-focused, uses moderate-power components, and the price difference is important. For a new gaming build, future upgrades, or higher-power graphics cards, a well-reviewed 550–650 W PSU with a stronger efficiency rating is the more conservative choice.
