Is 500w enough?

post #1 of 25
Thread Starter 
Right now I have an Antec Earthwatts 500w. According to the Newegg power supply calculator I have JUST enough to run it (Newegg says my rig needs 450-485w).

I'm planning on upgrading to a i5 2500k...when I put the changes in the calculator it tells me ~495w.

Do you guys think I'm safe keeping the 500w Antec? I was hoping I could hold out and get a new power supply once I buy a new video card a couple months later.

You want your power supply to be running at somewhere around 70-80% maximum capacity to receive the best efficiency. I would suggest upgrading to a 600W supply.

Only a 600w? If I'm going to get a new power supply I'd want one that'll last me a few years (and upgrade or two).

Keep in mind I only run single cards, never SLI/crossfire.

your fine. Dont spend any money if you dont have too. That 500w will be more than enough.

Only reason I would see to upgrade is if you plan on going sli down the road.

The point of owning a efficient power supply is to save money on your power bill. It kind of defeats the purpose if you end up spending more on a psu that you dont need to save money on your power bill. And the peak load will not make much of a difference for efficiency.

op: stick with your 500w unless you plan to sli in the near future.

Well then grab a 700 W, but remember, power efficiency is increasing, so if you reuse the 600 W device, it may work just fine in the future (unless they take those efficiencies and use them to clock higher, resulting in no net change).

I didn't notice in your first post, but this is something your going to be buying to replace a current supply. You should be alright with your current supply as is, if you want to save some money, but if you notice some glitching and such, then you might consider the larger supply.

Duuude, a 500W is more than plenty !
Those online calculators are not to be trusted at all.
Many at OCN tends to be overrating the wattage waaay too much.

If you want to upgrade to another GTX 460, I'd recommend the XFX 650W series due to their x4 6-pin Aux connectors. They have a modular one and a non-modular one. The non-modular performs a tad better than the modular.


You're only going to draw around 300W max with your setup. Calculate yourself instead.

This, unless you get sli you dont even need to consider upgrading it.

500w is enough, you're only going to be using 200-300watts on load

You're good. The 2500k will use less power than your c2d.

Woah, really? That'd be great if I could save the $50-100 it'd cost me for a new PSU.

I have a GTX460 right now, but I plan on upgrading in the fall. One would assume a new video card would be more powerful, but does that mean it requires MORE power? Or does it depend on the model?
