What PSU for my system?

[ntragas10]

Hello. I recently purchased an Asus Rx 580 O4G to pair it with my old machine for some 1080p gaming.

My PC specs are:
- i5 2500k oc%strippedEmail ghz cpu
- Gigabyte z68apd3 motherboard
- 2x4gb ram ddr3 1600mhz
- 1 SSD, 1 HDD
- 400 watt coolermaster PSU

I know that my old PSU cant handle that gpu load especially with an overclocked CPU.
Can someone suggest me a good budget PSU between 60-90 euro?
I was thinking of CoolerMaster MasterWatt 650 which is priced at 76 euro in my country or the Corsair CX Series CX650M at 71 euros. Any thoughts?

the CX650M would be a decent choice. However you could go lower on the wattage like a 550W PSU and higher on the quality like a Corsair TX550M

I used an online calculator and it recommended me the 600 watt Evga w1. This is why i was checking out the 600+ watts. If 550 is fine i could probably go for a better quality model.

You would be fine with a 550W

As for the 550 watt PSU, Seasonic Focus Plus 550 Gold and Corsair TX-M Series TX550M are in the same price range. Is Seasonic better?

I think both are wonderful PSUs and comes with 7-year warranty.
I think opinions are quite evenly divided - each brand has its own hardcore fans.
Seasonic is an OEM while Corsair is not - meaning Seasonic manufactured the PSU, Corsair gets their PSU from OEMs and rebrands them.
