Looking to upgrade my Graphics card, but need help

Last response: in Graphics & Displays
Share

Hi everyone,

I'm looking to upgrade my 6670 to a Sapphire HD 7850. However, My PSU is only a 500W and not entirely sure that my PSU can handle it (or even has two cords for PCI-E). If you guys could give me some advice on what I could do, I'd really appreciate it.

I don't really want to spend alot on a PSU, maybe something in the £30 (or less) range, if possible.

Thanks for any help guys,
I appreciate it.

Stomp can you do me a favor please! Can you please list your system specifications
CPU:
MOTHERBOARD:
RAM:
PSU: (You said 500W but can I get the company and model number for example corsair tx650,750,850,950)

There is a good chance you will not have to upgrade your PSU but knowing your other components as well as the strength of your current PSU will help me help you sir/and or miss.

Okay :) 

I used CPU-Z to get this info, cos I wasn't sure :) .

CPU: AMD FX-4170 4.4GHZ
Motherboard: MSI 760GM-P23(FX) (MS-7641)
RAM: 8GB
PSU: 500W, but not sure what make... The sticker didn't show any company logo, but i couldn't see it to well.

Thanks for the fast reply mate :)

I was going to reply to the other thread but I see you made a new one. Yeah I would defiantly not trust my components with that PSU. And again you can't cheap out on the PSU just like the GPU you will have to stretch out your budget more to accommodate a quality PSU, I can't stress enough it's the most overlooked part of a system.

It may just be the PSU that came with his case its okay to notice that a power supply is insufficient for your current needs. What I would do if I were you is get a newer power supply with a better 12 rail and better internal components I'll list one below its a bargain at the price its at. I normally would suggest a corsair power supply but this xfx power supply is also seasonic based as well (the oem or parts inside). It has 4 pci-e power connections which is something rare very rare at the wattage of this unit. If you can't afford the graphics card after getting this power supply I'd wait till the next series comes out and you may be able to get the the 7850 on the cheap :)

Awesome :)  Thanks for the suggestions..

Would I have to change anything because my CPU is overclocked?, or do I just plug and play?.



No nothing else need's to be changed, just unplug the power cord and swap out with the new power supply making sure to take your time and ensuring that all the connectors are properly installed.

Thanks guys. Just a few more questions.

What do I do with unused PSU cords?

How much of a boost in performance would I see if i replaced my 6670 with a HD 6870.

and how much difference in performance does the 7850 have compared to the HD 6870.

Thanks a bunch guys. You've really been a help :) .

You can hide the cables you dont use and secure them, it will make the interior of the case neat and tidy and also improve airflow resulting in lower temps. As far as the comparison between those cards I provided that in the other thread you have open.
Graphics card Master

Yea, what you can do is hide them yes. Get a bunch of cable ties and try and have it so there aren't cables around that you can really see in front. And in the back have it tidy so that around the CPU cooler cutout if there is one is clear.
NOTE: not all the time is this possible some cases have a easier time then others but you should be able to clean it up a bit.
I'll provide a direct comparison between the 6870 and the 7850. What to take away is this is that the 7850 does fairly well against the older card and also has a much easier time with DX11 games then the 6XXXX series had.

I haven't bothered with Anandtech benchmarks for years, ever since they showed a GTX470 outperforming a GTX480 due to old numbers (from an old driver version) being recycled on the latter. Anandtech are terrible for recycling old numbers rather than re-running tests. I've seen SSD benchmarks where they're reused numbers from a different test rig! See if you can find a driver version number on that page :-P

Check out those Tech Report links though, really interesting stuff!
Graphics card Master

Yea that kind of bugs me as a whole with most benchmarks but to be honest unless they recycle the results like you said I don't see an issue. The important thing to me is how powerful they are on release sure drivers can fix things but normally power on release will say something about a card. Its much too hard for these sites to constantly re bench graphic cards once a driver comes out people would be making A TON to do so.
Graphics card Authority

Agreed - 90%+ of the performance will be there at launch (with one or two exceptions - anyone remember Detonator 3/XP?). If you take a look back through Anandtech's articles, you'll see the exact same numbers (to the decimal place) in separate reviews. That's how I realised SSD results from different test setups (with different CPUs/RAM) were being combined.

I have to give credit to Anandtech for awesome explanations of new technology though. I learnt most of what I know about SSDs from Anandtech. I'd just never use them for benchmarks. Until THG brings in frame latency benchmarking (it's on the way) I'll stick with Tech Report for benchmarks. Problem is that it's a lot more time consuming that traditional frames/second benchmarking, and it's always a race between tech media sites to get benches out fastest.
Graphics card Expert

Yes those will work together Stomp. And yes the gtx660 is an option to consider but its another 30+ euros since the OP already had to stretch his budget higher to accomodate the 7850 over the original 6870 he was looking at and the PSU he also didnt originally plan on having to spend money on.
Graphics card Authority

Yeah XFX in particular are a safe bet - far as I know they're all Seasonic-manufactured units, so top quality. I have a Corsair and it's been rock solid for years (though given the choice now I'd take an XFX for the knowledge it's Seasonic).

I can't thank you all enouth for the help you've given me :) . The XFX psu and 7850 are on their way to me now :) . But just one more another question if its not to much to ask... I kind of overlooked this, but will the new psu and gfx fit in my Case?.
