ADATA XPG PYLON 550W 80 PLUS Bronze Non Modular Power Supply

A budget 550W unit with 80 PLUS Bronze certification and a DC to DC design that puts all 550W on a single +12V rail. A 120mm fluid dynamic bearing fan keeps noise down at low load, and the main capacitor is a Japanese 105 degree part. Full protection set including OCP, OVP, UVP, OPP, SCP and OTP.

Before you buy

There is no 12V-2x6 or 12VHPWR connector, and this is ATX12V 2.52 rather than ATX 3.x. If you are pairing this with an RTX 40 or 50 series card you must use the adapter supplied with the graphics card, and the unit carries no ATX 3.0 transient spike rating.

Non modular. Every cable is fixed. In a compact Micro ATX or Mini ITX case the unused SATA, Molex and floppy leads have to be stowed somewhere, and there is no way to remove them.

Only two PCIe 6+2 connectors. That caps you at graphics cards needing two 8 pin inputs regardless of the 550W headline figure.

Do not confuse this with the XPG PYLON II Bronze 550W. That is a different, newer unit that is ATX 3.1 compliant and does include a 12V-2x6 connector rated at 300W. Same family name, materially different product.
