[SOLVED] Do I need a new power supply?

[kacperzbyryt]

Hello, I'm going to upgrade my graphic card from a GTX 750ti to a Rx 580. My current power supply is a modular CX500M but the problem is that my PC was mounted in other country and they didn't send me all the cables that came with the power supply, so I have just the necessary ones. The card needs 1 x 8-pin + 1 x 6-pin so the question is: can I just buy the cables and use then normally because it's a modular power supply or do I need to get a new one?

You need to get the cables specific for that model of PSU. PSU modular cables are not interchangeable between brands and sometimes even models of the same brand.

Corsair or even Amazon should be able to source the exact cable you need.

You can buy cables to fit your power supply. But often those cables are more expensive or... Near price of a new PSU. If you are in North America, it's best to get yourself a new power supply. Although you should be able to run that rx580, depending on the rest of your system, it will likely be power starved. You should be running at least 550w with that card.

Seeing as the CX500 is a low quality unit that is not suited for gaming PC's now would be a good time to upgrade to something more suitable.

I agree that the CX500M is a lower quality unit, but it is sufficient for now:

What are the necessary cables that you already have?
While it might be possible to use adapters(not recommended), 550w is generally recommended for a rx580

I just have the cables for the drives and for the motherboard because my actual card doesn't need any cable, so I guess that won't work.

Oh god, that's big headache for me. I think I will opt for a new one then.

I live in Spain so that'll be a tad more expensive, but thanks for the suggestion.

Thanks for the reply. Any suggestion?

I think that there really isn't much of a magic answer.

New GPU at that tier would require you to upgrade your PSU, it's not enough long term (your 500w).

You'll spend time+money trying to figure out your cabling... Only to burn out your PSU once you set it up. It'll work, but it won't last. Upgrade is inevitable.


you've got done high prices for computer parts there [\b]

Yeah, that is definetly true. I'ts better to get a better PSU than going for the cheap things and destroying your entire system.

What are your other components? Which cpu are you using?

i5-4460 3.20 GHz
8GB RAM DDR3
Z87-G43 GAMING (MS-7816) motherboard
A HDD and a SDD wich name I don't know

That's a decent base for your new GPU. You've got a z board, it'll be a good pair for a 4th gen i7 upgrade if you feel
