Hi
I am looking at a Sapphire HD5770 1GB PCI-E graphics card. I have been watching videos about this card and apparently it only comsumes 108w of power. I currently have a 120w psu, but am going to upgrade to a 230/240w psu. I have pci-e slot on mb, so this card should fit in. I have a slim case at the moment but am going to upgrade to a full size case. Will this card fit into this mb even though it is a micro ATX mb? And also, will there be enough power to run this card? Will i be able to run this card properly?
Thanks
 
Are you running a custom built computer or a branded one? (if you are running a branded one, name and model number please!)

120w is nowhere near enough for the card and that system.
 
If you look at the system requirements for any 5770 it will say you must have a PSU of 450W or greater.

As long as you have a PCI-ex16 slot on your motherboard the card will fit, regardless if it is mATX, ATX, BTX etc...

Could you also post your system specs? This will make it easier for us to see if you'll be able to run this card with your current setup.
 
Dell studio slim 540s(soon going to change to full size case)
-Intel core 2 duo(2.93GHz)
-4GB DDR2 RAM
-ATI Radeon HD 4350 512MB(Hopefully changing it to a 1gb card)
-120W PSU.

Also, if i get say a 500w psu, would it do any damage to my motherboard or harddrives etc, from the current 120w?

Thanks for you reply :)
 
if its a non slim case, a 450-500 watt psu should be pretty affordable...honestly wouldnt recommend trying to stuff a 5770 into a small case anyway...

and as long as it has a full length pci-e slot, you should be good to go on the card
 
Would it damage my motherboard going from 120w to 500w? And also i think the video card i have now (ATI Radeon HD 4350 512mb pci-e) i think its ddr2, and the 5770 that im looking at is ddr5. Will this card still work even though its not ddr2?

Won't damage anything as the parts only draw what they need from the powersupply. the problem is when you have hungry parts and a tiny low wattage powersupply ;)

450W is overkill for a 5770 and any single chip card (apart from the fermi cards, but that is because of their huuuuuuuge power draw), you could run one on a 350W quality unit easily, however I would recomend getting a higher wattage unit. Not because you need all of the watts, but because you will then have further room to upgrade, and because at around 60% usage, is where most power supplies are most efficient

No, you will not to any damage, the system will only draw what power it needs. If you had a system that pulled 100W of power and you stuck a 1500W unit in there, the power supply would only be putting out 100W, being terribly inneficient and a waste, but not doing any damage.

Video memory is not like memory modules where your motherboard can only handle DDR or DDR2 or DDR3. So long as your motherboard has the right slot (in this case PCIe), it will work regardless of what type of memory is on the card

Dude, check again on that psu wattage, i highly HIGHLY doubt dell would ship any computer now with such a weak psu, 120watts?... especially one with a video card.
 
This could be a disaster waiting to happen.

You need a minimum of 450W as per manufacturers specs and you should really get something in the order of 500W however wattage means little and I would be suggesting something with at least 26A on the 12V rail.

Also worth noting that a standard ATX PSU probably will not fit in that case. Also be careful of any proprietrary dell motherboard connections.

PSU suggested (if it fits): Corsair 550W

However based on your obviously limited knowledge, i wouldn't attempt this upgrade.

You would be surprised what they ship these out with. My mum's HP has a massive, huge whopping...140W PSU in there :rolleyes:

I some what agree with the atleast 26A on 12V rail, however some of the lower brands will have high amps on their 12V rails but the rails are massively over volted, have high fluctuations and deteriorate so fast, so I would stick with a good branded unit of a decent wattage, is easier for OP to understand, as you say, he has limited knowledge ;) The 550W you suggested would be a good choice.

As to it fitting, he said in one of his many other threads :rolleyes: that he is getting a new case too. Should be pointed out to OP though about the new case, Dell sometimes like to use custom or non-ATX form factors, so the motherboard may not fit into the case without you drilling some holes to fit your standoffs in, which complicates matters further
 
that core 2 duo processor might just prove to be a bottleneck while playing the latest games with that video card,that is,you might not be able to utilize your graphics card to its full potential...could you plz post the exact model number of the CPU...?

450W+ is what the manufacturer recommends.

You're right though that it'd be a good idea to get a higher wattage unit to make it more future-proof if he decides to upgrade again later on.

And like everyone else has been saying and anyone who is knowledgeable about computer parts will tell you, get a decent brand of PSU, in the 500W range would be perfect for what you are looking to do with it.

Alot of people that build computers don't know computers. Look at the desktop section of the forum, we help to build systems for people, and they dknow how to put them together, but not what is good or needed. An "ok" 450W unit would probably power it, but you get a good, solid brand and 350W would do it. It is a recomendation to try and hit the middle ground of quality. Just because food says best before doesn't mean it will go off at midnight on that day, it will still be good a few days, or maybe even a few months after
