Strongest GPU I can put on my current PSU?

sparrowFX · Feb 16, 2015

Hello! I am in need of help from experts here on tom's

I currently have this little "gaming" rig. Not actually gaming since I don't have dedicated GPU.

CPU: Pentium G3258
RAM: Kingston HyperX Fury white 4 GB
MBO: Asrock H81M-HDS
PSU: Energon EPS-650W

Currently I am using Intel HD graphics card but this week or next I'm gonna buy used GPU ( sadly can't afford a new one )

The question is, will my PSU Energon EPS 650W be sufficient for cards like HD 6950 or HD 7850?
This is the link for that PSU

I plan to upgrade my PSU in next 3 months to a CX 430 or 500.

I found really cheap XFX Double D 6950 and am considering buying it. What card would you recommend to me ( there are few options I have in mind, HD 7850, HD 6950 and HD 7770 although for extra 20-30$ I can buy the 6950/7850 instead of 7770? I plan to upgrade this Pentium to an i5 later this year so don't look at the possible bottleneck, because when I buy this GPU I will have it until it dies.

First of all, don't buy a CX 430 or 500. Don't buy a CX PSU at all. Upgrade to this when you can

The Antec I listed can handle pretty much any single card around.
For the GPU: I'd get a 6950. The powersupply you currently have can handle it, but a CX 430 or 500 can't

Why not wait for the upgrade of psu first then upgrade gpu. Now you are very limited because of the quality of the PSU. I would suggest this

it can handle most of the single card out in the market now.

^What he said.
Both the PSUs linked (gwapito's and mine) will handle most single GPUs and the 750W Antec will support a few cards in SLI (probably not CFX, though)

gwapito :

The thing is I need a dedicated gpu since Intel HD graphics are pretty bad for games I play. Like I said I would upgrade my PSU asap, just wanted to ask you guys will this psu I have currently supply enough power for this card I'm going to buy and the rest of my PC.

sparrowFX :

I completely understand you but instead of getting a low end card why not upgrade the psu and get a mid card. Among the cards that you mention 7850 will give you better gaming experience that will work good with your cpu.

Base on the packaging of your psu, it can handle 7850. But i don't recommend it. look at this link and read the comment:
