What’s actually slowing this PC down?

AMD lists the RX 570 at 150 W typical desktop board power and recommends a 450 W minimum PSU. Treat 450 W as a starting point, not a guarantee that any 450 W unit will run every PC: check your exact graphics-card model, the power needs of the rest of the system, and whether the PSU has the correct native PCIe cable.
How many watts does an RX 570 need?
AMD’s current RX 570 specifications list 150 W typical desktop board power and a 450 W minimum PSU recommendation. The 150 W figure describes the graphics card; the PSU must also power the CPU, drives, fans, and other components. A system with a higher-power CPU, overclocking, or additional hardware may need more capacity.

Check the graphics-card maker’s recommendation for the exact model you own. For example, MSI recommends a 450 W PSU for both its RX 570 ARMOR 4G OC and RX 570 GAMING 4G. MSI lists power consumption of 150 W for the ARMOR and 120 W for the GAMING; these figures apply to those models, not every RX 570.
Do these 3 things before closing this tab:

The 450 W recommendation is a baseline from AMD and these MSI examples, not proof that an unknown, aged, or poorly designed 450 W unit is suitable for a particular complete PC.

Which power connector does your RX 570 use?
There is no single connector requirement that can safely be assumed for every RX 570. MSI specifies one 8-pin power connector for the ARMOR 4G OC and GAMING 4G, but another card variant may differ. Find the full model name on the card or its label, then check the manufacturer’s specification page and the socket on the card itself.
Make sure the PSU has a native PCIe cable that matches that socket. A PCIe 6+2-pin plug combines to make an 8-pin graphics-card connector. ASUS’s cable guidance identifies 6+2-pin/8-pin PCIe cables for graphics cards and warns not to force connectors. Do not mistake a CPU/EPS cable for a PCIe graphics-card cable; they serve different connections. If a plug does not fit easily, stop and verify that it is the correct cable and orientation.
Rank #2
- Fully Modular PSU: Reliable and efficient, low-noise power supply with fully modular cabling, so you only have to connect the cables your system build needs.
- Intel ATX 3.1 Certified: Compliant with the ATX 3.1 power standard, supporting PCIe 5.1 platform withstands 2x transient power excursions from the GPU.
- Keeps Quiet: A 120mm rifle bearing fan with a specially calculated fan curve keeps fan noise down, even when operating at full load.
- 105°C-Rated Capacitors: Delivers steady, reliable power and dependable electrical performance.
- Modern Standby Compatible: Extremely fast wake-from-sleep times and better low-load efficiency.
Do not treat SATA-to-PCIe or Molex-to-PCIe adapters as a default fix for a missing GPU cable. Without documentation establishing that an adapter is suitable for the specific PSU and card, the safer choice is a PSU with the required native PCIe connection.
How to assess PSU quality beyond the wattage label
An 80 PLUS badge concerns energy efficiency, not overall PSU quality. MSI describes the program as an efficiency certification. It does not, on its own, establish electrical performance, reliability, protections, warranty, or fit for your system. Compare efficiency separately from those other considerations.
Rank #3
- High Efficiency & Stability: Rated 80 Plus Bronze certified (≥85% efficiency) with rock-solid voltage regulation for reliable PC performance under load.
- Whisper-Quiet Cooling: Engineered with a silent, durable 120mm fan that delivers effective cooling while minimizing noise disruption during intense gaming sessions.
- Versatile Powerhouse: Semi-modular design and 750W capacity (ATX standard) offers flexible cable management and robust wattage headroom for demanding gaming rigs & upgrade paths.
- Comprehensive Safety Armor: Full suite of protections including OVP, UVP, OPP, and SCP guards your components against electrical faults and surges.
- Clean Aesthetics: Features sleek all-black cables - no garish red/yellow "ketchup & mustard" colors – ensuring a sophisticated build look inside your case.
Check the exact PSU model’s documentation for listed protections. MSI’s selection guide identifies common abbreviations:
- OVP: over-voltage protection.
- OCP: over-current protection.
- OPP: over-power protection.
- OTP: over-temperature protection.
- SCP: short-circuit protection.
Protection labels are useful items to verify, but their appearance in marketing material is not independent proof of a unit’s build quality or performance. Corsair explains how protections such as OVP and SCP operate in its PSU protection overview; claims about product coverage there apply to Corsair products, not every PSU.
Rank #4
- 80 Plus Bronze certified for high efficiency
- 120mm Low Noise Fan
- Industrial level protection with OVP,OCP,OPP,OTP, SCP
- DC-DC Circuit Design
- Active PFC design
Where credible independent testing or model-specific electrical-performance information is available, use it alongside the manufacturer’s specifications. Also consider the unit’s warranty, age and condition if reusing it, and whether its physical dimensions fit your case. An efficiency badge or a large wattage number should not substitute for these checks.

A practical checklist before you buy or reuse a PSU
- Identify the card. Record the full RX 570 model name and verify its power recommendation and connector on the card maker’s page.
- Check whole-system capacity. Use AMD’s 450 W minimum recommendation as a baseline, then account for the CPU and the rest of the PC rather than assuming the GPU figure covers the system.
- Confirm the cable. Verify that the PSU has a native PCIe cable and the correct plug configuration for the card. A PCIe 6+2 cable can form an 8-pin connector.
- Review the PSU itself. Check exact-model protections and technical information, independent testing where available, warranty, age and condition, and case fit. Treat 80 PLUS as an efficiency indicator only.
- Do not force a mismatch. If the plug or cable is unclear, consult the PSU and GPU documentation. Replace an unsuitable PSU rather than relying on an unverified adapter.
