As the title states, Here's the link to the machine http://www.newegg.com/Product/Product.aspx?Item=N82E168...

Thanks in advance for any help given. My budget is around 100-150.

How much does that thing cost? Because it seems like a very weak build. Also, I couldn't see the psu, what psu does it have?

220 watt. I bought it from a friend for 200 a while back ago, I play a wide variety of games and not all of them run smoothly on low settings.

There is not much you can do with a 220 watt psu (and it is likely not even going to supply the listed amount). If I were you I would look into getting a solid 550 watt psu and gtx 650 ti boost, and definitely upgrade that ram and cpu. To be perfectly honest, that system is very dated and not much can really be done to upgrade it and if I were you I would save up some money and just build a brand new one.

Sorry, you most likely need a new system or atleast a new psu before you change gpu. It sucks I know.

I would suggest a HIS 7750 1GB ddr5@$99 + shipping($3)
Good for gaming at 720p medium settings.
It has low profile bracket for you case.

Your system is currently being CRIPPLED in games by the 210 which is only really a video adaptor.
The 640 was actually designed to play games specifically in this situation. The difference between the two cards is night and day. At medium settings and resolutions the V2 KEPLER will play anything the cpu can.
Be very careful to get the V2 KEPLER , not one of the other two versions because they are weaker in games and use more power.You must get the small form factor bracket too, so its not an easy find.

Freakout, its a small form factor rig, I dont think he is up to a complete system rebuild into an atx case, and if he was it wouldnt be worth the effort with a phenom quad.

Will the 300 watt psu requirement be fine in my 220?

the old card uses 21 watts, you are increasing max load by 28 watts.

The card I mentioned is a low profile card(with normal size bracket attached, but a low profile bracket comes along the accessories).
pls check the link.

The 7750 is beyond his psu, or I would have auto picked it.

I also owned a slimline like you and wanted to add a better graphic card, but considering all the constaraints like the small form factors and low wattage psu, I decide to get a new case + gpu + psu.

Although it cost more but I thing that would be the best thing to do.(or you can get a hp slimline psu with more wattage if it is still available on the internet)
I mean you can go with a better graphic card but It would be risky(if things dont work out properly, all you investment could be wasted).
I think that case PSU has around 12A ratting on the 12v rail.

What you can also do is get a 300W psu for you slimline. It may cost you around $30 and if you would do so, pls check the 24pin cpu connector of the psu, The slimline model that I had, was having a mini 24pin cpu connector(the motherboard also had a mini 24pin socket).

Max actual system consumption tested for the ddr3 gk107 version here is 208 watts.
Kepler is 15 watts lower.Max actual system draw SHOULD drop in under 200 watts.
...more...


208 -15 = 193watts
and he has a 220watt psu that is not certified.
Even if it was certified for 80+ bronze and suppose was giving 83% of the total wattage on max load, even then the total wattage delivered would be 182W.
Still 193>182 and I just dont think the OP would be happy if he runs into some issues due to low wattage after buying parts.

ps: I know the thread is answered very nicely by chrisso, but just wanted the op to make a well thought decision.

I know the maths , I'm a qualified sparky.My speciality is fault finding and trouble shooting cowboy installs.
I had already worked out everything you said as soon as I looked at the machine. I also worked out from him saying he bought it from a mate for 200$ what sort of 'customer' he was;
'no Enthusiast' is the answer.
I concluded the psu being HP o.e.m. (probs out last the board with stock equipment) will likely handle being pushed to the edge occasionally.(The figures quoted are playing METRO , remember,it wont be playing that 24 /7)
And the psu will likely fade slowly, by which time having pulled it apart once to put the gpu in, when it starts to crash at max power the poster will realise he cant get out of buying a psu and putting it in, and he can now do it himself.
Some people learn the hard way. Praps he only looking short term. When he uses the new card he will realise the machine isnt crap and worth extra $30.
You cant teach em everything in one go, you just do the best you can.
You did well to try tho, but in my xp you are shouting without an audience.

There is one other thing I forgot to mention.The card I picked is pci-e 2, not 3, and 64 bit interface, not 128.
This is more likely to be compatible than the 7750,but there are no guarantees. .

I think this forum is about helping people and I intend to do so, not to make them learn things the hard way. I just don't want the OP to have issues even after consulting the forum (the forum loses credibiltiy this way).
I want to tell him as much as I know and try to explain things as much as I can.

I know my first post was not clear enough, sorry I was at work.
I dont doubt you knowledge or experience but I just dont want the OP to have troubles and want him to be clear about all the things and issues that he might run into.

ps: I am guessing this discussion is leading nowhere as there have been no posts from the OP afterwards, so I guess I wont be repling anymore on this post.

Many years ago, I learnt the hard way. I bought a cheap power supply, not being a member of this forum.
I HAD BEEN TOLD tho ! It was an EZCOOL 650. It looked the biz, blue led on the fan and everything.
I only needed 450 watts, so thought I was covered. 12 months later I had to buy another at £27. 8 months later, that one expired and took out my northbridge chip, and one of a matched pair of xms2 2 gig sticks.
That is £120 spent and grief instead of a £50 psu in the first place. You cant make em drink.
Good luck.
