Bronze vs platinum

[Exonoz]

Just wonder something,
I run 2 770 cards in SLI and I use Corsair's TX750M 80 Plus Bronze power supply.
So thing I wonder about is that if i upgrade to a gold or platinum power supply, will I see some form of performance, or will the durability of the card go up?

[Morpheus]

neither,  you'll just save a little more on the electric bill. I don't think it helps the card's durability or anything like that

[Capitalist Jesus]

No and no. The only way to increase the "durability" of the card is with a low noise/ripple unit.

[Imaginaerum]

You wouldn't even see a noticeable savings per year on your energy bill unless they were in use 24/7, then you might see a drop but some people don't think it's worth the premium of a Platinum PSU.

No and no. The only way to increase the "durability" of the card is with a low noise/ripple unit.

You could also put carbon fiber armor on it!

 

@Exonoz Despite it being a power supply, it isn't a 'power up' that in anyway improves performance of your parts.

The only thing that would be more durable would be the PSU I believe, since to achieve greater efficiency it has to be made with higher quality components

The mere upgrade to bronze to gold/platinum PSUs doesn't affect performance of your system. What these certification tells you is the amount of energy during the AC-DC conversion are usable for your computer that isn't wasted as heat. If your system are drawing 500w AC from the wall, your PSU will be supplying 400w DC to your component if your PSU is 80% efficient, where the other 100w is wasted as heat.

 

To some extent (with diminishing returns), the PSU can set some limitation on your system, and that is overclocking. If you had made achieve the best overclock that your system allows without experiencing overheating and instability with that TX750M, "upgrading" to an EVGA NEX750G may yield you different results. Results that may be worse than good. This is because of voltage regulation, and the NEX750G, being a group-regulated design, will have looser regulation that the VRM of the CPU/GPUs needs to deal with than your TX that is DC-DC regulated. This would either require you to bump the voltage up (which also makes it hotter) or lower your OC.

On the other hand, getting a better performing unit such as the AX760/760i, Seasonic X 750 KM3, Cooler Master V700/850, Antec HCP 850w Platinum, Antec Signature 850w Bronze, or the EVGA SuperNova 750/850 G2 when it get release, you may be able to achieve the same overclock at lower voltages or better overclocks with the same voltages.

 

But like I had said, it will have some diminishing returns, that chances are, you likely won't appreciate the upgrade, unless you are hardcore overclocker that is planning to set near record overclocks with a fully custom water loop or LN2... Basically, you should only considered a new PSU if you are building a completely new rig and the better unit is in the same price range as another lesser unit. Otherwise, your TX750M is already a solid unit that you don't need to replace.

It does give off that impression considering how all of the best quality PSU that are sold today are typically either Gold or Platinum efficient. However, you can make a low quality unit with high efficiency. You may start to see more of them soon, as this is a transitional period where there are more Gold efficient units being introduced in the lower-end mainstream segment, in which there few cost cut components being used in them.
