SFX L POWER 500W
The be quiet! SFX L POWER 500W is a 500W SFX-L power supply rated 80+ Gold, fully modular. Independent lab testing puts it at A for noise, averaging 23.9 dB(A) across the load range, meaning quiet under load. It is out of stock at the retailers we track right now, but the specs below still apply whenever it returns.

Quality score
How we score →A power supply has no performance benchmark: every 500W unit delivers 500W. This scores how well built and how liveable the SFX L POWER 500W is, out of 100, from six published factors.
Better always scores higher, but the steps are uneven on purpose: Bronze to Gold is worth 11 of the 25 efficiency points, Gold to Titanium only 6. A factor we hold no value for scores zero rather than being skipped, so a unit we know little about never outranks a fully specified one. That does mean a zero can mean either poor or unknown, which is what the confidence figure above is for. Physical size scores nothing: SFX-L is a fit decision, not a quality one.
Measured in the lab
Everything else on this page is a specification the manufacturer published. These figures were measured from the SFX L POWER 500W itself by Cybenetics, an independent test lab.

Each figure is an average over more than 1,450 load combinations, which is not the same measurement as the 80+ Gold badge on the box. That badge certifies the unit at a handful of fixed load points; this covers the whole range, including the light loads a desktop spends most of its time at. Lab figures exist for roughly a fifth of the units we track, so their absence on another page means that unit has not been through this lab, not that it did badly.

Compare all GPUs →The graphics cards this 500W unit meets the system requirement for, ranked fastest first at 1080p, with the margin left over. The resolution follows the wattage, because a unit this size is bought for a card that will be run at 1080p. Headroom is measured against the card maker’s own whole-system recommendation, so 0 W means it meets that recommendation exactly rather than falling short.
