Is it bad to have too many watts on a PSU?

[Noah M]

Hello! I asked about what PSU I should get and someone said 550 watts and then a website says around 450 watts. Lets say I buy a PSU with 800 watts, would it be bad for the computer and all of its components since it has a lot more watts?

No, It won't do any damage to your computer, plus, it leaves some space in the future for better components, so you can upgrade your parts a bit if you want.

Hope this helps!

Nope. The PC will only use the amount of watts it needs to operate and nothing more. Wattage overhead is actually a good thing because it leaves a lot more room for future upgrades (if they will need more power) and overclocking. However it is better to spend on a high quality PSU with less wattage than a low quality PSU with high wattage because the quality of the components matter in the PSU's efficiency and reliability. Refer to this list if you're looking for PSUs to buy. Never go below tier 3. www.tomshardware.com/forum/id-2547993/psu-tier-list.html

No it is not bad. The components will draw as much power as they need and not more. Generally you should allow a headspace of 20% for your power supply (500W load, 600-650W power supply),More wattage, though, don't always equal a better psu. Meaning a 800W no name psu is not better than a EVGA g2 550w. First comes reliability.

No Problem

The only downside with a PSU that has such excessive capacity of wattage is your computer will be less efficient because it'll be such a small load of the maximum potential, which makes it lower on the efficiency curve.

Does anyone know if a "800 Watts - Standard 80 Plus Certified Power Supply - SLI/CrossFireX Ready" is good or bad?

It depends what one. 80 Plus certification means nothing except saving a few bucks on the power bill for some additional yearly beef jerky. And SLI/Crossfire support basically is a marketing gimmick.

Hey, not related to the topic, but, how do you get that "power supply informer" Picture?

Thanks in advance

I made it myself. It was actually a gif, with an actual animated power supply exploding, but I happened to lose the image source temporarily, but have a still image of it, so that's it right now. I upload it to Imgur, then in my Tomshardware personal info, under signature, put it in IMG tags.
