Default Should I keep using my current PSU?

I've made a lot of recent upgrades to my computer. Currently sitting with an i7 4790k, a GTX 970, an SSD and HDD storage setup, and 16GB of ram. Earlier in 2015, before I got the graphics card and the new CPU my old power supply blew and didn't have the patience to wait for an online order. I went to Best Buy and the best thing I could find was a CX850M so I got it retail.

Is this bronze unit, which actually got a decent review by jonnyguru, good enough to keep in my computer? Should I look into maybe a 850 G2 from EVGA? I'm only asking because with the new i7 and new SSD and new graphics card I want to feel safe with the power delivery I have. (For reference, the power supply is taking air from under the case)

Your PSU isn't even 50% loaded with that rig. Therefore it's fine for the application, even if nowhere near high-end.

If you haven't already owned it, i would certainly advise you to look for much better alternatives, but...
since you already bought it, i think that you can use it for about 2 years, and then change it with something better.

That's what I thought actually since jonnyguru's review actually mention's test 3 going into silver range and despite its 30c rating it beat the hotbox. Would anyone know if this PSU, the CX850M, would allow me to turn on EUP in the UEFI bios? Its the 1W while off/standby thing.

Yeah, as I said in my post it was the best purchase I could make considering I didn't want to wait for a replacement to get shipped. It's funny too how my old power supply is absolute crap even compared to the CX850M. I had a OCZ ModXStream 700W, it died twice. The second time wasn't under warranty so that's where I got the Corsair.

Isn't the CX850M a PUQ-B??
So something with DC-DC...

Yes. The CX750 and 850 use DC to DC and has a 140mm fan. The lower wattages are group regulated with a 120mm fan (for now).

Best Buy has a very limited supply of PSUs. The alternatives are worse (Rocketfish, Dynex, etc.)

But I will say that 850W is tremendous overkill. I can't imagine that an 850W was the *only* thing they had in stock.

At the time of purchase my computer's parts weren't quite low power. It was definitely still overkill but not by as much. I knew I wanted a corsair compared to anything else they had and they only had a couple different wattages of the CX series.

Also what's DC-DC? Is that good?

DC-DC in that context is the method of deriving minor rails (+3.3V and +5V) from +12V using dedicated VRMs similar to ones you have on your motherboard. It improves voltage stability and efficiency compared to other common regulation methods.
