Can You Have Too Much Wattage Power Supply
What to look for when swapping the power supply.
Replacing a power supply is a common solution to some issues. Make sure yous have the correct wattage ability supply. Bigger doesn't injure.
I want to upgrade my current case that has a 300W PSU to a nicer looking case, but information technology has a 520W PSU. Is information technology ok, and how does the "Due west" deviation influence PC operation?
Information technology'southward quite all correct, and if things were working well before, y'all probably won't even notice a difference.
Allow's expect at why, and just what that "Westward" means. I get questions on this topic often.
More than watts: is it safety?
It's quite safe to install a ability supply with a higher wattage rating than the ability supply it's replacing. The wattage rating just indicates what the ability supply is capable of. Bodily power apply is adamant by the computer's ability requirements.
W is for watts, which ways power
The "W" stands for watts, which is a measure of electrical power.
Power supplies are rated by the maximum corporeality of power they tin can evangelize. That means a power supply rated for 520 watts can supply more than electrical ability than one rated for 300 watts.
That'south more than electric power. Information technology won't brand your reckoner run faster or give you more "computational" power — this is merely most the electricity required to operate your computer.
The power you demand
If your computer has been running well on a 300-watt ability supply, so it doesn't demand a bigger ane.
Only at that place'due south nothing wrong with using a bigger one. It's possible that a new, larger power supply might be a piffling more efficient or perhaps a footling quieter.
Your estimator will continue to use any amount of power information technology was using before, which nosotros know is less than 300 watts. That your new power supply might be capable of providing more is beside the betoken.
Fourth dimension for upgrades
A new ability supply is typically called for in one of two situations:
- Your existing power supply has failed, or is in the process of failing, and is no longer able to produce the power your calculator requires. It might be rated at 300 watts, but due to whatever is failing, it'southward not capable of providing power anymore. As the ability supply fails, unexplained crashes commonly become more frequent.
- Y'all've added hardware in the form of add together-in boards, retentivity expansions, boosted hard drives, or other devices that depict more power from your computer, and y'all've exceeded your power supply'southward rated chapters. This, too, can behave like a failing power supply.
In either example, the solution is a replacement power supply.
In the showtime instance, a power supply with the aforementioned rating as your old i will do; in the 2nd case, y'all'll need ane with a higher wattage rating.
Future-proofing your power supply
If you're going to replace your ability supply, I recommend replacing information technology with 1 that has a college wattage rating. It hurts zippo to practice so (other than, perchance, your wallet, depending on how far you go).
More than to the point, it makes your machine more than capable of supporting additional hardware power requirements in the future.
What a power supply will not do
I've heard concern that a high-wattage power supply can somehow "force" power into the figurer, causing overheating and exhaustion.
This is wrong.
A power supply supplies power in response to demand; it doesn't push power anywhere. If your computer only needs 100 watts, then a 500-watt power supply merely supplies 100 watts. Why have a 500-watt ability supply? For "meridian" usage (sometimes hardware requires sudden "bursts" of ability, such as at startup or nether loftier load) and for futurity expansion.
It's meliorate to have too much power than also fiddling.
Ability supply requirements
There are ii more than of import aspects of power supplies, replacement or otherwise.
If you exercise supplant it, get the correct size. By this I hateful concrete size — in that location are several standard sizes out in that location, and they are non interchangeable. Similarly, the number and type of connections provided by the power supply must friction match your calculator'due south needs.
Make sure the machine is well ventilated. Using more than power means generating more heat, and that estrus has to get somewhere. That's what ventilation is for. Even for your existing working system, make sure things are well ventilated.
Brand certain the fans in your machine are working properly and that the airflow is unobstructed. Overheating due to blocked airflow may be the most common cause of figurer hardware failure — in particular, the power supply itself.
A discussion nearly laptops
If yous have a laptop, you're out of luck. Laptops come with the batteries and power supplies they come with. There's no real fashion to "upgrade" their power chapters.
