Can a good psu increase performance?

post #1 of 8
Thread Starter 
I bought a Antec True Power 650W a week ago and I was just wondering, can a good psu increase performance of videocards and other components? My Ultra XVS is powering all my components so far but I do not entirely trust it, I am running with 4 molex cables connected to the 2 6 pins on my 260gtx, a review I read on it was it may not be able to power better cards than the 8800gt and this was several years ago.

I havent got around to installing the antec yet as im going to put it in my new build.

no, but a good PSU can be pushed further and not break down, were cheaply made ones with die and probably take other components with it.

Good PSU can't increase performance, but a bad one can degrade performance.
So if you had a poor PSU and upgraded to a better one, you might see performance improvements, although such cases are very very rare.
Poor PSUs usually cause just instability/damage.

PSU can only increase perfomance if the parts in the PC were being starved of power to begin with and now they are getting sufficient power.

No, it can't. however the better the build on the PSU, the less of a chance you will have of something going wrong and the unit exploding.

No. The only possibility is that somehow if a GPU or CPU does not get enough power i will not function properly and may result in performance drop.

This.

Im sure there are more people PSU limited than we think. A piece of junk PSU supplying erratic voltage could cause instability long before you got to the clocks that would be the maximum for a given estimated voltage.

Well that's settled.... lol!
