Will This Power Supply be Enough

[iineviidable]

I am about to order a GTX 680 and was wondering if this power supply would be enough.

I'm pretty sure it will but I want to be sure since the 680 in itself is 500+ usd, I don't want it to go to waste 😛

If you could spring $20 more there is a much better 650W supply:

Which is super flower based. And it will be more than enough

For a definitive answer you'd have to provide data for the rest of your system, but unless you are running a lot of surprising stuff, it should work fine.

Nvidia say 550W for a GTX680, though some versions will recommend higher as I've seen ones that use an 8pin PCIe connector.
In reality, a 500W is likely to be more than sufficient as a reference GTX680 shouldn't pull over 200W by itself. (195W tdp).

Coolermaster PSUs are pretty hit+miss, though that one looks ok. You might want to consider having a look at some of the alternatives in that price bracket though.
EDIT - one that redtailed suggested is nice but it's $40 more after rebates

I currently have a 500 watt, but if i'm understanding things correctly, its only 12v 25a and the 680 i think needs 38a or something

i5 2400 3.1 (3.3 turbo)
8 gb ddr3 ram
Gigabyte z77x-ud3h motherboard

^^ Those are the important specs btw 😀

Yeah it probably won't be sufficient, your "500W" PSU can only put out 300W on 12V, which is where the vast majority of the power is needed these days. A good 500W PSU will have a 12V amperage of maybe 35-40A which would be more like it.

Best value stuff I can see at a glance is
XFX 550W- $55 after rebates - http://us.ncix.com/products/?sku=59615&vpn=P1550SXXB9&manufacture=XFX

But also newegg have huge rebates on Corsair PSUs, making them very good value-

Yeah, that is only 300W on the 12V rail and pushing it depending on the PSU model.

That CPU will draw 95W, the 680 195W, and everything else probably 75W. That is 365W with everything maxed out.

So a *good* PSU with 450W+ on the +12V PSU should suffice.

This 550W would be one of the best 550W:

Thank you for the help, but i have one last question.

I want to use my 550 ti as a physx card too, but if i can't no big deal, won't hurt my feelings.
I went with this power supply: http://www.newegg.com/Product/Product.aspx?Item=N82E16817139028

Would it be enough to use the 680 and the 550 ti?

Thank you for your help too,
I have one more question i wrote as a reply to Rammy.
If you could give some input too it would be much appreciated 😀

Yes, it will be enough power wise unless you heavily overclock. But that supply won't have enough PCI-E power connectors - it only has 2 and you will need 4. You could use a Molex to PCI-E power adapter or, but that would not be ideal. In general, you only get 4 PCI-E connectors in 650W+ power supplies, so a 650W would be better.
