Corsair 650TX & new Haswell chips

Marketing. There is a slight power consumption savings for deep idle, but it would take over 10 years for the investment of buying a new power supply to pay for the power consumption savings.
 
As long as it is supplying consistent power & has enough juice for your video card/system, I wouldn't worry about the PS.
 
Connectors are identical -- it's the ATX standard. So yeah, marketing thing. You can read here: http://en.wikipedia.org/wiki/ATX

I just bought the Corsair HX750 which is also marketed as Haswell-ready. I would recommend stepping up to the HX-series. One nice feature that you'll get is that the power supply fan actually turns off when the load is light.

There's a $20 rebate AND a $20 coupon code that ends today.
 
I don't think it's entirely marketing. From what I've read so far haswell has some really low power idle modes that some older/cheaper power supplies don't support, but it's a setting you're suppose to be able to enable/disable if you want to. http://www.tomshardware.com/news/Intel-Haswell-PSU-Power-State,22320.html Manufacturers should have a list of which of their psu, old and new, that support haswell's low power states, but here's a list I found http://techreport.com/review/24897/the-big-haswell-psu-compatibility-list your tx650 should be compatible.

Sounds right. Haswell is all about power savings. Which doesn't matter too much on desktops IMO. Haswell is all about laptop battery life.

Good info, though I wouldn't run out and spend $100+ on a PSU just because of this C7 state.
 
Thanks, all, for the info! I'm glad I won't have to spend the extra $$ for this upgrade.

Why the PS question: I'm running an Athlon X2 64 5600+ and am planning to go to the 4770K. I haven't chosen a motherboard or memory yet, but am leaning towards Gigibyte or Asus. I've used Gskill before and they have a great reputation so I'll probably use them.
 
Nice. I am still chugging along on an i7-950 and have no reason to upgrade for a while. I'll probably wait until Skylake hits in 2015 (14nm).

Be sure to post some benchmarks once it's up and running.
 
dparm,
Any MB standouts you'd recommend for the new chip with Gigibyte or Asus? Its really hard to take customer reviews seriously on Newegg and the like. Looking to spend no more than $200 on one (a tad over is OK).
I'm not an overclocker/tweaker trying to get the most possible out of a build. I may dabble with stock overclocking features down the line, but that is about it.
Thanks.

Best advice I can give is to buy the one with the most/best reviews. The best-sellers are typically safe-bets.

ASUS has been more reliable than Gigabyte in my experience.
 
I think the warranty they offer is probably more important than the brand. eVGA has some very long warranties -- to me, that means they believe in their products.
 
No, it just seemed to have all the needed features (I'm guessing) and has had good reviews. I have a Coolermaster HAF 922 so space isn't a problem. If I needed a sound card I could get a PCIe one.

Any reason not to get an mATX like this? Before I saw this one I was looking at regualer ATXs and they are more expensive it seems.
 
No, not really other than the # of PCI/PCI-E slots, which, if you aren't going to use them, becomes a moot point.
 
It does have 2 PCIe 3.0 x 16 slots so I should be good. My video card is an XFX 6950 2gig. If I could find another one down the road and go XFire it would be cool, but right now it will do the job.

The desktop processor series generally have two memory channels, so two DIMMs are already optimal and four won't perform any better. For these, IMO the only reason to use four DIMMs is if the price works out better. Here are the specs on the i7-4770K:

Some server processors have three or four memory channels. For example, the E5-26nn series, like this E5-2660, have four channels so it would be optimal with four DIMMs:
