Which PSU for an Intel i5-2500K with minor overclocking?

[itakey]

I've had good luck with Antec's.

How many watts do I need give or take? I'm guessing 500W+ will do it, but I've been out of the loop for quite a while.

I'm building a machine and so far I'm planning on an i5-2500K that I'll do some very minor overclocking. I'm going with a z68 chipset and plan on using built in video so I won't need a ton of extra juice in that respect.

I'll probably run 3 or 4 internal drives, and between 8GB and 16GB ram.

This 550W Antec has great reviews:
Antec BP550 Plus 550W at $74.99

Antec EarthWatts Green EA-380D Green 380W Continuous power at $44.95

Recommendations?

If you not going to have a discrete graphics card, then 500W is already way more than you'll need (even with some serious OCing).

If you don't mind a rebate:
XFX ProSeries 450W - $63 ($43 AR) shipped

Otherwise, it's either that Earthwatts 380D or this:
Antec NeoECO 400W - $47 shipped
http://www.newegg.com/Product/Product.aspx?Item=N82E16817371029

I like the XFX because it's a Seasonic-made PSU (they make high-quality PSUs) and it's 80 Plus bronze rated. The Antec NeoECO is also Seasonic-made, but the Earthwatts is made by Delta (maybe not as good as Seasonic, but not bad either).

Any would work and you'd still have headroom for a discrete low- to some high-end graphics card should you decide to add one.

Thanks for the recommendations.
The first one you posted has mediocre reviews so i'm sort of looking at the other, or the other antec's.

Thanks for the tips on Seasonic, didn't realize all of that stuff.

So would a 380W do it, or should I stick closer to the 500W range?

380W would MORE than do it.

a 2500k system without a discrete graphics card will pull like 60 watts at idle and maybe 120-150W at load TOPS. 350-400W range gives LOADS of headroom for you.

Perfect! How about if I have 4 Sata type drives running, maybe one is a green drive but the other is a caviar black and other similar drives.

Check the hard drive specs, they'll state current draw on 12v and 5v lines, calculate the wattage used. Most are 5-10w at tops. A little more than that at startup, when it's spinning up to speed, but at startup your CPU is essentially idle.

My 'typical' idle value I listed will include a drive or two. I think my machine idles at 63W on the IGP with 2 7200 RPM hard drives and an SSD. Hard drives don't use much power. 380W has plenty of margin for a machine without a discrete GPU.
