Holy ancient system Batman! That is a junk PSU. get a better one. I wouldn't trust it to run your system, as it is, much less with a GPU.

Thanks logainofhades. My other option is a Radeon Hd 5450 1gb, is my PSU enough to power this card.

logainofhades - he's pretty much summed up running a "junk" of a pc, so it kind of fits :\

Mdven - it will run it wihtout a sweat, but if You want to keep that PC alive for a little more, try to get some cheap but good xfx psu.

 

[LLCamara]

Not enough, really. Go with a minimum 350w PSU with at least 80% efficiency (i.e. bronze certification)

EDIT: same goes for the HD 5450. The difference in consumption between both is small

 

[logainofhades]

Not calling the PC junk, while it is quite the dinosaur. It is that PSU that is junk. Even a cheap 80+ Evga 500w would be vastly superior to that Bestec, with regards to quality. I have seen plenty of those stock HP, Bestec PSU's fail.

 

[Mdven]

So all of you think it's too risky if i buy the radeon r7 240? Or could be handle it by the psu. At least until i can buy a new pc (not in a short time).

 

[logainofhades]

I think it is too risky, to be honest.

 

[Mdven]

I only want to keep alive a little more my very old pc with a card that i can use later in another (not so new hehe) system.

R7 240 ain't the sharpest tool in the shed for "new rig". And since You can get her from 46 euro, I think it's worth the risk.

Thanks, so one vote for "too risky", another for "worth the risk". Anyone else want to vote? hehe.

And the other option, radeon hd 5450 i think has the same power consumption than r7 240, right?

 

[mdocod]

The Risk of PSU failure is going to be about the same with or without the GPU: High and getting higher with every passing day.

 

[uplink-svk]

mdocod - that's a "double vote", now he's gonna be even more confused 😀

 

[Mdven]

And what about a Gt 520/610?

HD 4350 is another option.

My doubt is that all video cards i mentioned above have almost the same power requirements than r7 240 and hd 5450, no?

 

[mdocod]

Just throw a GPU in there and hope for the best. If the PSU wipes out the system it won't be a significant loss. I bet the whole thing is worth less than $50 at this point.

 

[uplink-svk]

They're powerfull in this order:

1. R7 240 [100% raw power - reference]
2. GT 520 [this one is crap] [37% raw power]
3. GT 610 [this one is total crap] [36% raw power]
4. Radeon HD 4350 [this is ultimate crap ultra] [18% raw power]

Go for the R7 240, try it out.
