PSU influence on overcloxking potetential

[Alim]

Does quality and addiyional featutes of PSU affect OC performance? Can cheaper PSU bottleneck overclocking? Both PSU have same or higher wattage

[Octavialicious]

As long as your psu gives the pc enough power and doesn't explode, it doesn't affect performance 

[AlRayes_BRN]

Never go cheap with the PSU

[WoodenMarker]

The psu doesn't affect performance, If a psu doesn't supply enough power, the system should simply not boot or shut down. 

[LogicalDrm]

Cheaper PSU will limit overclocking in that sense that it might not be able to keep enough power running to CPU when you up the volts.

If we put it differently, does the battery of your car affect how fast your car goes? Obviously not, however if you don't have enough power than that will be a problem. Anyway, don't cheap out on the PSU, buy something from a reputable brand with a bit of headroom to spare in case you decide to upgrade later. Also good PSUs last for years and can be used in many builds down the road. I have my Cooler Master PSU for 5 years already and it is still running like a champ and I have used it 3 builds already with a fourth coming soon.

Actually it does on high-performance (read: turbocharged) vehicles 

 

@OP a quality power supply can influence the stability of your overclock. For instance ripple voltage is a lot lower on high-end power supplies.

 

I personally recommand the EVGA G2 series.

A bit off topic, but explain to me how the battery makes a car go faster, I really want to know. This is like stating that cold air intakes give you more Bhp...  

[Alim]

I meant can cheaper PSU cause lower stability (like being unable to provide stable 1.3V to CPU) on overclocked system or it's just matter of power?

I have option of $40 700W and $150 750W PSUs

Cold air helps to deliver more oxygen to the engine

When your car is light up like a christmas tree with tons of gauges (boost, oil temp, a/f, blah blah blah) and an aftermarket ecu with run triple walbro fuel pumps for your 2000cc injectors on e85 ethanol it puts a huge load on your electrical systems; especially at WOT. Sometimes people put in really small batteries to save on a weight or fit massive 4" intercooler piping in the engine bay and they'll get electrical issues like voltage drops that reduce the fuel pumps's output.

You people need to get your facts right here, for a car enthusiast this extremly frustrating, not going to argue any more. 

 

PS: A cold air intake doesn't give more power, best case scenario 1-2Bhp more and that is with a twin-turbo charged car.

That is something completely different man. And it is not that the battery matters, but that its capacity matters, which is completely logical. It's like trying to run a 2x 295X set up on a 700W PSU.

On a 2jz-gte it's a 20hp gain at stock boost levels.

semantics, the battery affects the capacity (among other things) 

 

But anyways back on OP PSU have more characteristics then just output. Ripple voltage is a big deal for instance.

as long as you don't get a very cheap unit it should not affect your overclocking as long as you have enough headroom on the PSU to provide extra current to your overclocked parts (this can represent a good amount of extra current being used)

That being said the power supply is the heart of your machine and if it goes pooof it can take down several component with it (again if it's too cheap of a unit) so i highly suggest you cousult experienced PSU reviewers website's and check reviews

for the units you are looking at BEFORE making your purchase of a new PSU...some brands offer excellent AND poor quality units even corsair does that so check them reviews out. good luck!
