What Power Supply would be good for this build?

[SgtSlinky]

Intel Core i5-6500 3.2GHz Quad-Core Processor

MSI Z170A PC MATE ATX LGA1151 Motherboard

Corsair Vengeance LPX 16GB (2 x 8GB) DDR4-2666 Memory

Crucial BX100 250GB 2.5" Solid State Drive

Western Digital Caviar Blue 1TB 3.5" 7200RPM Internal Hard Drive

Asus GeForce GTX 970 4GB STRIX Video Card

NZXT S340 (Black/Red) ATX Mid Tower Case

[Synawke]

id say a 500-600 watt EVGA G1 Supernova

[Guest]

EVGA G2 650/750 ect

[Castdeath97]

750W-650W for if you plan to SLI in the future, 500W for a single card.

[Oshino Shinobu]

id say a 500-600 watt EVGA G1 Supernova

Not the G1. GQ, GS and G2 are good units. 

[Castdeath97]

EVGA G2 650/750 ect

Overkill if he doesn't plan to anytime SLI though.

[glitchmaster0001]

EVGA 650 Antec 650 or seasonic 650w

A potato. 

Seriously though, anything with more then 600 watts and a good name brand on it is gonna be good. 

My recommendations are: 

http://pcpartpicker.com/part/evga-power-supply-120g10650xr

http://pcpartpicker.com/part/thermaltake-power-supply-sp650pcbus

Or anything by corsair. 

[Oshino Shinobu]

EVGA 650 Antec 650 or seasonic 650w 

EVGA and Antec both have bad/meh units in their line-up. Best to be specific with the models or people may still end up getting a bad PSU. Seasonic is always a safe choice.

Overkill if he doesn't plan to anytime SLI though.

who knows what the future predicts.

It gives a lot of upgradbility.

Don't say Overkill. 1,500w is overkill.

This is enough room to add another GPU, Overclock and overclock the GPU too

The NEX (G1) series from EVGA is not great. Neither is the TT SMART series. 

 

Corsair have some pretty bad PSUs, and the rest are overpriced. 

 

If you want a brand that can be recommended as a whole without stating models, then go for XFX (Seasonic OEM), Seasonic, Superflower, Delta and Cyonic.

A 970 will only pull 340-360W this leaves enough for overclocking. So, two way 970 SLI is the only time he will need more than 500W.

Well, considering the possibility of more HDDs, pumps, fans and so on + overclocking, 650W isn't really overkill.

Power supplies are hard to get wrong. CX series only seem to have higher failure rates because they are purchased more often, thus making bad reviews of them more common. Same deal with other power supplies. G2s and superflower are fine if you want to spend too much money, but I do agree with the SeaSonic or XFX PSUs, they seem to be reasonably priced. 

[ITS-PARTY-TIME]

550w seasonic, xfx, evga g2,gs,gq or superflower

The CX series is bad for high end builds. The reasons for the failure rates is the poor ambient temp tolerances, poor quality caps and general build quality. The G2s are very reasonably priced. They're around the same as a Corsair RM series, but they use all Japanese caps, unlike the RM series, which use lower quality secondary caps. Seasonic is probably the best PSU OEM on the market (bar Delta, maybe). XFX uses Seasonic exclusively as OEM, as do Cyonic. 

 

EDIT: It's also pretty easy to get a sub-par PSU. Just because they don't blow up doesn't mean they're good. It's the one component that you definitely want to get right, considering it holds the potential to kill all other PC components.

TDP isn't the max it will pull from the wall, just what its rated to do. A 120w card will pull more then 120w just by itself. Look at the amperage and wattage on the 12v rail for the PSU and use that number, not all PSUs are created equal. And give yourself 50w or so of headroom over the max your system could pull. 

(And a 970 can pull 450-500w in a system.)

my bad. i meant G2

CX does use lower quality secondary caps, but RM does not as far as I've read.

Source? Most reviews I have seen can't make the full system pull more than 400W.

I'll clarify that the RM series is not bad. It's just overpriced for what it is, when you can get better units for the price. The RMi and RMx units are better quality, but more expensive than units of the same quality.

 

The CX series isn't bad either, when it is used in the intended situations (office and basic builds, as stated by Corsair)

The EVGA GQ 650W has been on sale for 70 dollars on Amazon for awhile now so go for that.
