PSU Recommendation for Custom Build

[Appletax]

I'll be building a gaming PC for myself soon and need to figure out how many watts the PSU
needs to output. I've read that you should use 50-75% of the PSU's output for
efficiency.



Here's the parts:

EVGA GTX 770 - 304 Watts MAX w/ 30 amp +12

Intel Core-i7 4770K - 84 W
PSUs that can handle Haswell's C6/C7 states (0.05 A on 12V rail)

Asus Sabertooth Z77

Samsung 840 Pro 256GB SSD - <1 W

Corsair Vengeance 8GB RAM PC3-12800

Corsair Air Series 120mm Case Fans x2

LG Blu-Ray ROM

Noctua NH-C14

Read through that.


I'd consider quality first, then total wattage and then the bells and whistles.

You should be fine in the 500-600W range, no need to go higher then that. Just make sure the amperage is what you need it to be on the 12V rails.

For yourself? because if its for yourself get a good high watt one..psu for you is an investment that will stay with ur future upgrades for a long time. If its for a client id go with brandonkicks suggestion.

Seasonic power supplies are my favorite...outstanding quality...they're like tanks! They happen to make many of the power supplies (they're an ODM too) for many other "high end" brands.

A 650 will be fine...750 if you feel like tons of headroom.

The GTX 770 that I want maxes out at 304 watts... Should I stick get a 650/750?

Just read a review of this card w/ 6 core Intel i7 and total system load was less than 400 watts

EDIT: http://www.extreme.outervision.com/PSUEngine recommends a 424 PSU

Why you still asking, are you really trying to get cheap on the psu and go for the bare minimum. Buying a 400 dollar video card and trying to squeeze a few bucks out of life line that powers the entire system and all its components?

has a 20 dollar rebate it expires tmw. its modular, 850watts so its very future proof.

No interest in getting a cheap PSU. I just don't want too many watts because
I run the risk of under-utilizing it, which is inefficient.

Planning on getting a Corsair HX750. I had wanted an 850, but read that that's
overkill for a system like mine. Also read that a high-end system w/ GTX 680
only needs a 550 W PSU, 2 680s goes to 750, and 3 go to 950.

750 watts seems plenty. Thought about AX version, but the reviews say that
the AX is not significantly better than the HX. HX is quite a bit cheaper. Seems
like a better value. Read that it's CWT? brand and not SeaSonic.

NO NO NO V2 is seasonic! Do not get the V1 thats CWT and thats not as good as seasonic.

I think you are under the impression that the psu is going to use the amount of watts its rated at. That is not the case at all.

Doesn't matter if you get a 600 watt or a 1500 watt the system isn't going to use any more power than it needs...well...technically a higher quality psu is usually more energy effecient.

I always prefer single rail design. To the op, big thing you want to look at is not wattage. Biggest thing I look for is the number of amps on the 12v+ rail. The more the better. That and the efficiency rating, 80+ certified is always good. The bronze silver and good ratings are obviously great to have.
