Manufacturer description
The SANSUN 12V 5A power supply is the workhorse adapter you reach for when a retro build, a strip-light run, or a shelf of surveillance gear needs clean 12-volt DC and the original brick is long gone. It takes AC 100-240V from a standard US plug and delivers up to 5A / 5000mA at 12V DC, giving you 60W of headroom for anything drawing less than 5 amps: 0.5A, 1A, 2A, 3A, or 4A devices all run comfortably from the same brick. The 5.5 x 2.1mm barrel jack is center-positive with a 9-foot cord, so you can place the adapter at the outlet and still reach a monitor, external HDD, router, ADSL modem…
SpecPicks Verdict
SpecPicks scored SANSUN 12V 5A Power Supply using a rating × review-volume × price-fit model applied to published specs and reviews across the power supplies & cables category. SANSUN's power supplies & cables lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here. Judge it on the specification table and the price rather than on sentiment: check the figures that decide your use case, then put it side-by-side with two or three close alternatives in the Compare tool before clicking through.
Common buyer scenarios for power supplies & cables of this kind: matching it to an existing build, replacing a failing part, or upgrading from a previous-generation equivalent. Check the spec table below against your current setup — particularly socket / form-factor / power-rating fields — and confirm compatibility on the retailer's listing before purchase. Prices and stock are set by the retailer and may have moved since this page was last updated.
Frequently Asked Questions
Will this power a 12V LED strip without soldering?
Yes. SANSUN includes a female DC barrel connector with screw terminals, so you clamp the strip's bare positive and negative leads directly. At 60W it supports roughly 12 feet of standard 5A-class strip; check your strip's stated wattage per foot.
What size is the plug and which polarity?
The DC barrel is 5.5mm outer diameter and 2.1mm inner diameter, wired center-positive with the outer sleeve negative. Measure your device's jack and confirm its polarity symbol before buying, since center-negative equipment can be damaged.
Can I use it on a device that only draws 1A or 2A?
Yes. The 5A rating is a maximum, not a forced output, so 0.5A, 1A, 2A, 3A, and 4A devices draw only what they need. Do not use it on anything requiring more than 5A at 12V.
How long is the power cord?
The output cord is 9 feet, which lets you keep the adapter at the outlet and still reach a wall-mounted surveillance camera, an LCD monitor on a desk, or an external HDD on a shelf across a small room.
Does it have any built-in protection?
SANSUN lists over-voltage, over-current, short-circuit, and over-temperature protection. Specific trip thresholds and warranty terms are not published in the listing, so check the current Amazon product page or contact the manufacturer for those details.
