View Full Version : Would a High Watt PSU Increase System Performance?

Ok I just bought a 550watt Psu from Newegg. I am wondering if it increases anything at all? I used to have a 330watt intel PSU.

I'm not sure if that is even a really good Psu but I got it.
It won't make the sightest bit of difference to the performance.
Considering that most of your money is probably going towards the clear case and the UV sensitive sleeving, I doubt that the quality is up to much either.
If you wanted quality and really needed 550W, you should have spent about twice as much and ignored the bling.

I thought it looked cool. I'm going to be making a whole new gaming system soon. Anyways if anyone could explain what to look for in a PSU and what it does.
Thanks,
Eric

well if you are getting a gaming pc, make sure your psu has an available pcie connector(assuming your going pcie) looks like your's has one(four pin connector), mine came with 2. a higher end card takes alot more juice, make sure you can cover the cards need along with the rest of your system.

Ok ApacNTS I got that but what about Voltages. I don't know anything about that.

The voltages will always be the same.
There's the 12v, 3.3v and 5volts.
It's just the amps it can put out and what connectors it has that you need to worry about.

Ok the amps, do I want High amps or Low amps

The higher the better.
It's not just about how many amps it can put out though.
The original specifications called for relatively high amps on all the rails.
The updated specifications call for the available power to be skewed more towards the 12V rail. So much so that one 12V rail is no longer considered sufficient, most good PSUs now have 2 or even 3. Look for dual rail, sata power, pcie (2 if you are thinking about SLI).
The other thing to consider is quality. All the power for your expensive gaming system goes through the PSU. If you get a poor quality one the chances of it failing are that much higher. And if it does fail the overvoltage protection is likely to be absent or insufficient to protect your other components from damage.
Flashy cases and components are all very well but in reality how often do you actually look at them, particularly the internal components. If it's a gaming computer, are you going to be playing games or sitting there admiring your case?

Modern systems are skewed towards the +12v rail...ideally you would like to see a minimum of 35 amps there.
Furthermore, you would prefer that the amperage is delivered continuously...i.e. the voltage does not vary much from idle to load.
The problem for you, the consumer, is that there is no industry standard for measuring the output of a PSU- they can pretty much say anything they want.

At Lynx: I'd like to do both, but the next computer I build that will be all gaming won't be so pretty. Here is what I am going to get.

For now I'm just going to stay with one card untill I get more money for another.

For a good Gaming PSU, you want dual 12v rail at 30+A.

The retail CPU comes with a cooler. Try it first before you decide to buy a cooler.

The PCI-E connector is six pins :whistling
The 4 pin in-line connectors are run of the mill legacy ones,
and unless I'm mistaken, every PSU on the face of the planet has those.
You may have been referring to the mobo auxilliary power connector....

anyway i wouldn't get an el cheapo psu, if you want to then go ahead. But seeing how much money you're spending on the stuff like cpu, and vid card, i think you can afford something much better.

yup nice correction, complete mind fuck when i typed that. was staring at the aux cable after i closed the case thinking about how to wire it all together when i buy my pciE card. hence my stupidity. :oops:

Urgh, a nice plastic case to let radio interference in and out.
Keep your mobile phone away from it, you would not want it to loose regulation
and blow your other components to bits.
Laptop PSU's generally have a reasonable amount of metal screening inside the plastic case.

Huh?
When did laptops enter the picture?
