550W or 650W psu?

[urg773]

Hi,

I've posted a few days ago about this build/parts, and I've almost decided, but.... what about the psu? In the list there's a 650W psu but a 550W one would be good to, no?

I want to build this:

PCPartPicker part list

CPU: Intel Core i5-4590 3.3GHz Quad-Core Processor (€199.00)
CPUcooler Do I need one??

Headphones: Kingston HyperX Cloud Headset (€94.00)
Total: €1310.00


I'm not thinking about sli or overclocking and maybe I'll just add a extra hdd or ssd and some more fans in the future.
So, should I choose a 650W or a 550W psu (or....)???? and why?

Thanks.

550 should be enough, even for your extra HDD/SDD and fans... 650 would leave you room for extra stuff if you ever need it.

go with a quality 550W psu that should give u room to OC your GTX970

go for something made by seasonic or XFX Corsair Avoid VS/CX they use cheap capacitors and transformers

super flower also makes quality PSU and i think CM Vangaurd PSU's are good

A 550W PSU should be able to run the build - even if just barely. But if I were you, I would go with the 650W PSU you have chosen because there is no doubt about it being efficient enough and it should last for a long time. Getting a PSU with bigger wattage also helps in the future in case capacitor aging becomes a problem in the long run. It is not like you would save a lot of money by taking a 550W PSU instead so paying perhaps 10€ more for a little peace of mind is not much if you ask me.

Power supplies will age and lose a little bit of output over time. Go with the bigger unit if you can and then you have extra headroom.

Minimum recommended wattage for NO OC GTX970 is 450Watts i think 100 more watts will give him room to OC the cards

so a 550Watt quality PSU will be more than enough for your system

Go with the XFX TS 650W Bronze. I'm going to buy it and it's always better to have more W.

I would personally go with the 650W one because it doesent cost much more and will futureprof your build more. You can even use it in future builds so you dont need to buy a new PSU then.
But otherwise, You should change the Cooler Master to the EVGA SuperNova G2 650W. It is regarded as the best 80+gold PSU in the market because of its phenomenal quality (100% Japanese capacitors). very nice sleeved cables and the double ball bearing quiet fans that don't even spin under 40C. Have one myself and I could never be any happier. Pricing-wise its not a huge difference. Definitely change the PSU.
