Hello internet. I am OC'ing my i5 2500k, as well as buying a GTX 670. What PSU would you recommend for this operation?

On second thought, this would be better suited in power supplies. Mods to the rescue?

no reason to spend $110 on a 650 watt psu for that simple build. there should be some some decent 550--650 watt psus on sale for half that price that are way more than capable of powering that system reliably. the Corsair TX650 I have is decent quality and was only 60 bucks. it does not even come close to having to work hard with a similar system as the OP. the most I ever saw it pull was right at 300 watts max at the wall with everything oced. that means only around 250-275 real watts max is all this system will pull and my psu fan never even has to go up from its idle speed.
 
No reason? I beg to differ...

If $110 is too much, then yes you can get somewhat decent PS for less.
But if you want a top notch PS, fork over the $110 and get the PS linked in post #2.
 
A corsair 750wtt will do. Unless you plan on SLIing in the future..
 
750 watt not enough for SLI?
That's nuts.

Pretty sure I could run SLI with my Seasonic 650. Currently with just one video card, the only time I could even get the Seasonic's fan to turn on was by overclocking the video card and running heaven for a bit. Even then the fan was off most of the time!

Then again, I guess if you are running a couple of those higher power cards (580, 6970, 7970), and pushing the clocks on both cards and the cpu quite hard, 750 maybe not enough...
 
How much power do you guys think a GTX 670 uses? Have you not noticed the dramatic power reduction in the Kepler series? The OP's entire system probably doesn't pull much more than 300W under full load.

A Corsair CX430 V2 for $35 from newegg after MIR should be fine for his system, though at the moment the CX500 V2 is just $5 more.
 
what ever wattage/price your looking for
just make sure its corsair

I already gave a good account of what the OP can expect to pull.

I would not get a CX series psu though. they are made with lower end parts and their power ratings are made at 30C instead of 40 or 50 for better quality psus. they also make very little power on the 12v line relative to their overall wattage rating. that CX430 only makes 336 watts max for the 12v line so that is not suitable for any decent gaming pc. the CX500 makes 408 which is much better but again those ratings are at 30C which is not realistic. I would spend 15-20 bucks more and get a more suitable psu.
 
Good deal on the Lazer

Platinum KingWin 550 right now at Newegg.

I think 550W may be enough for some nice over clocking but I think you would be better off getting more power so you are not always pushing your PSU at 80% of it's max rating when you are over clocking. Also I slightly larger PSU may better suit your needs later on if you think about getting another video card for SLI.


Looks like a good PSU just make sure these power requirements will meet your over clocking and future power needs.

Why pay more for a 550W PSU when he can spend $10 less and get a silverstone PSU with more wattage? I don't know about you guys, but the things I upgrade the least are my case, my monitor, and my PSU. With a unit like a silverstone, why not future proof with extra overhead on the wattage? It's not like to OP said that price is a huge concern. Buy less, buy better.

Based on my now 2 year old rig I'd have to agree, I've been running a Corsair TX750 for a little over 2 years without any issues and my hardware isn't very power efficient vs. current Video cards & CPUs. (GTX 480 / i7 920 oc'd 3.4ghz / 4 internal 7200rpm HDDs, Dual burners).
 
Always try to future proof and never get anything that is poor quality. I have to second the above with the Corsair TX750. I have this PSU in one computer, and the TX850 in another. They are the best rated ones in existence.
 
I pretty much only go for Corsair and Seasonic at this point. If you're looking to futureproof and this is your main gaming rig, I suggest between 650-850w. That Seasonic 650 (or the 750 if you can find it is excellent as well) on sale is the best you're going to find for that price - Gold certified and fully modular.

The KingWIn Lazer Platinum 550W was highly rated by [H]OCP and JohnnyGuru in their reviews.

KinWin can run at Gold standard ratings at over clocked 650W. Platinum level at 550W.


Seems like a good choice for a nice Platinum rated PSU for the money.


The key is making sure 550W is enough.

I have over clocked HD7950 and over clocked i5-3570k with high amperage fans and fan controller and water pump + 6 SATA powered drives. I went with Seasonic Platinum 860 because its high quality and will easily meet my most intensive over clocking with plenty of breathing room. Also my psu is more future proof in case I want to add another card or two or buy an entirely new higher power mb and cpu.


For the OP's requirements I do think the Kingwin Platinum Lazer 550 will meet his needs.

Seasonic is my favorite PSU builder right now. They make great power supplies and have good customer service. I like Corsair as well but I prefer Seasonic.


Seasonic should have some new lower powered PSUs that are platinum rated soon.

Right now Seasonic is only offering platinum rated PSUs in 860W and 1000W but soon higher power and lower power platinums will be available.
 
650 Watts from a reputable company is fine.

Heck, I use a hx650 for my gtx 590.
 
Go for a Seasonic, or an Antec rebrand of a seasonic (like the Antec Truepower new). You can get a Antec True Power new 750 for around $100. It is a Seasonic, and as good as it gets (just not as effecient as it gets, Bronze rating) .

I have also had very good experience with FSP. But I would still take the seasonic over the FSP.

Stay away from anything else

...you realize that lots of companies sell Seasonic rebrands? No need to stay away from "everything else"...when internally they are the same.
