Is a PSU upgrade required?

[ConfusedDolphin]

 A friend of mine wants to upgrade his computer by changing out his video card for a gtx 760. 

 

The rough specs of his computer are: 

 

CPU: AMD FX 4100 @3.6GHz 

Video Card: GT 620

HDD: single 500GB Hard Drive 

Memory: 4GB

PSU: 450w (no-name brand with no efficiency rating) 

 

He would like to be able to play Rome 2 Total war on High Setting at a decent fps (~50fps)

 

My primary question is if he upgrades his video card to a gtx 760 would he need to upgrade his power supply to something with a higher wattage and/or better efficiency rating from a trusted brand? 

 

I was thinking about suggesting a Corsair cx series 500w...

 

Any help/advice would be greatly appreciated  

 

P.s. I only suggested that he upgrades his video cards but Is there any aspect of his system that any of you would consider in dire need of an upgrade? I have floated out the idea that he upgrades to an SSD for general SSDs are awesome reasons.

No, but it is recommended

I'll honestly just upgrade the PSU. Might not even put out 450W and let alone inconsistent and unclean power. The power supply you suggested is more than enough.

 

I'd throw in the SSD after if you got the cash for it. Graphics card first

I would. Some no-name brands shouldn't be trusted to even 200w.

You should probably replace the psu.

It isn't "needed" but definitely highly highly highly recommended, also your friend isn't going to get 50ish fps in Rome 2 with those specs at high haha, that game is demanding as fuck.

I would never trust a no name/brand psu to output the wattage they claim it will, just get a new one to be on the safe side.

do you need upgrade your cheap 450w PSU for for a GTX 760 ?

 

yes!!!, of course, absolutely  :lol:

 

 

 

but, if you buy something... buy "something good", go for a 650w/80plus

eh, he could get away with a 550-600w psu

eh, he could get away with a 550-600w psu

so ?, i say buy "something good" (not a new cheap bigger PSU)

yeah, as in a better 550w-600w powersupply, like gold or platinum 80plus, sorry for the misconception
