Hey guys, I was wondering if a 500W PSU would be powerful enough to run my new build.

Parts:
AsRock B150M-Pro4 Motherboard
Cryorig H7 CPU Cooler
Intel i-5 6600 CPU
ASUS GeForce GTX 970 Strix DirectCU II 4GB
Corsair Vengeance 16GB (2x8GB) DDR4

I was looking at the Corsair CX-500 V3 Power Supply.
Cheers guys!

I wouldn't buy it new, CX are not suited for a gaming rig like yours. but yes it will work. It's just that there are a lot of things besides "work" and "not work" when it comes to power supplies. There is voltage regulation, crossload performance, transient response, ripple suppression, quality protection circuitry, good build quality.

Instead, get the XFX TS 550: http://www.newegg.com/Product/Product.aspx?Item=N82E16817207013

Op is pushing a skylake cpu, and while still a very good psu, I'd not go with the older designed seasonic. The EVGA G2 550w would be a better choice. As Turkey said, the CX aren't really designed for a gaming build, even Corsair agrees to that, the CX is a budget line designed more for home-office use. For the xfx I'd go with the TS Gold, not the bronze, or even the XTR.

Exactly. The Seasonic is an older design and doesn't tolerate low power modes in C-States 6 or lower like sleep very well, even to the point of not being able to come out of sleep at all. This can be gotten around in bios/windows power settings by maintaining sleep settings at C-3 and no lower. It's an incompatibility that started with Haswell cpus and while not detrimental in the slightest way to normal waking performance or high power loads, it does take some by surprise when they continually have to reboot after the pc enters a sleep state. It's really more an annoyance than anything else considering the quality of the S/M 12-II as most pc owners are more used to plug-n-play not components that periodically might require maintenance.

I thought it was the Pro series that was group regulated and based off the S12ii. Is it also the TS?

The TS bronze is the same GB build as the S/M 12-II, XFX Core. The TS Gold is a G build same as the XTR, Seasonic G series and S12G. But that's only the 520/550/620w group, the 650/750/850w are AT/AM builds. Not sure about the newer EVO series from Seasonic and I've heard conflicting stories about whether the entire line or just some of the XFX are Haswell compliant. From what I've heard, it's only the 650w and up are, the 520/550/620w still being group regulated and not Haswell compliant.
