How much watts and which PSU do i need

[GirvanaWantsBinnieBalls]

• r7 1700
• gtx 1070
• gaming mouse/keyboard
• led strips
• rgb fans 
• I will most likely overclock my 2400 mhz ram to 3200 ( if possible ) 

How much watts do i need? will a 550 w psu do the job ? What if i overclock the cpu as well , can the 550 do the job?

Also , i can buy a bronze certification for 70$ ( Corsair CX Series CX650M ) otherwise if i want gold certified ( Corsair TX-M Series TX650M ) ill have to pay 90$ . 

 

Other than the energy efficiency , is there any other significant difference ?

As you can see money is a bit of a problem not because i dont want to spend much , but the cheaper the psu is the sooner ill get it ( i got like 20$ now  )

 

I got everything but the PSU

550W is plenty. You would technically be able to squeeze down to 450W, but 550W is sensible and leaves more room for upgrades as well as possibly running a little quieter.

 

A CX550M would be a fair starting point. A gold-rated PSU will save you a bit of money over time and likely also be quieter, since there's less heat generated inside the PSU.

550 is enough. 650 for sure.

Yes, certification does not really mean much, as you can see from here:

The two PSUs you chose are good, as long as they are the 2017 version.

The TXM is a better unit overall so although you probably won't see a difference now, the TX will probably last longer, as reflected in the warranty.

A good 550 will be fine for that system. I personally suggest ~600-650 in case you want to upgrade to a more power hungry system down the line, since good PSUs can last through multiple rigs/upgrades

I got a 700W Bronze from EVGA for $60 a little while ago. But 550W is probably fine, but OC would be a little sketch without a bit more juice

450W is plenty when overclocked. It's a 1070 and a Ryzen, not a Vega and X299. Where do you get your information from?

Btw, $60 for that B1 is not a good price, unless you actually need the wattage for something like SLI Fermi.

TBH I know next to nothing about OC, so you're probably right. In regards to the PSU I mentioned:

Back when I bought it, I was in desperate need of a new PSU. The 6 pin PCI connector on the OEM PSU I had was broken and wouldn't supply power to my 960 properly. I looked on Amazon for good PSUs and was planning on getting a 500W, but it had fewer SATA power cables and was more expensive than the 700W. I said "F*** it" and got the 700W as future proofing. Since then I've added more drives, upgraded to a 1070, upgraded from an i3 to an i5, upgraded to an AIO, and added multiple case fans.
