Hey me again =D, I was just asking if I could upgrade this onboard card to a Radeon 5770 without buying anything else. Here is the computer that I has.

I'm not sure how to check the PSU, any help would be much appreciated. Thanks,

[DeadJediJamie]

I'm going to say that the power supply you have is probably insufficient to suit your needs, as most branded machines like Dell and HP only put the wattage that will supply the components they installed.



While I'm not sure what it is like inside the case, you will also need to make sure you have sufficient room, as most cards nowadays are quite long and branded cases tend to be notoriously lacking in room.



This is by the by in any event since I'm pretty sure your power supply won't be sufficient so you won't be able to buy just the 5770.

[Gorath Alpha]

The power supplies that are included in most of the HP desktop PCs are barely adequate to handle a business class video card such as an HD 5450, but might manage to support an HD 5570.  I haven't used an HD 5770, nor have I read the card manual for it, so at present, I am only guessing, but I would imagine that an upgrade to a 430/450 watt aftermarket power supply such as this one would be in order:

That's a Fortron for $45, a decent brand.  The majority of power supply brands are poor choices, no matter what claimed wattage is involved.

Motherboard and such are good?, problems only exist in size and power supply?

Thanks guys.

You can check your PSU by open your casing and read specifikations on the label that is atached to your psu.
Follow the advice from DeadJedJamie, and check that you have sufficient room for your new card.
My guess however, is that your power supply will be sufficient, they are not labled with high watts but they deliver what they promise.

According to HP, there's only a 250w PSU in there



http://h10025.www1.h...product=4299992



and according to this Tom's Hardware article, the 5770 is rated for 18W idle and 108W at full load

[Chim3ra]

So blood, according to your sources it's acceptable? Sorry, I'm kinda dull in this area. haha

[DeadJediJamie]

You could risk it with the power supply you have, as BloodDragon83 says, but I would seriously consider not running that card with that power supply. While it will probably run, there's no telling what will happen under full load. Either nothing, or blue screen.



Please tell us what it says on the sticker for your PSU. Look for the number listed under the heading "12v" that's usually a sound basis of figuring out whether it will supply enough clean power for that card.

[blooddragon83]

I did a quick check on the Antec PSU calculator and with the main components (CPU, GPU, RAM, HDD, DVD-RW) at 90% load, it would recommend 279W. Now you won't be running that full of a load most of the time, but when you're full-screen gaming you could be pushing that PSU to the limit. I'd look at a good 350W-450W supply; the one recommended by Gorath would work great.

Guess I have to upgrade then, well time to find out how to change a psu, easy?

That depends on how they've wired the PSU you have, if they've routed wires into difficult to reach places then things can become troublesome, however, in most cases it's real easy to do.

[blooddragon83]

It's pretty simple, just make a note of everything that was connected to your old supply and make sure it's connected to the new one

I am going to expand upon that reply.  The author of this question arrived here a couple of days ago asking about "high settings" in another thread, which I would now assume is why the HD 5770 is what he is asking about.  However, I always prefer to offer assistance in another way, and that's to start from two things, being the screen resolution at which the game will be played, and the available budget to cover the upgrade, from which to see what compromise is possible.  If the existing display is only a medium resolution device, the HD 5770 is going to be quite adequate, but there is a range of possibilities, and I didn't get as far as the specs for that part when I visited the linked Best Buy page. 

If it happened to be a 19" 1280 by 1024 or the wide screen equivalent, even the HD 5670 would run with high settings. 

OK, I revisited the Best Buy page, and that was a bad deal at that price for a stand-alone PC tower with no keyboard, mouse, speakers, or display.  Another instance of Best Buy pricing being a BAD Buy.  I suppose a wide screen would be about 1400 by 800 or some such and have the same number of pixels.

I'm playing at 1600x 900, it's a 20'' screen. As for budget, I have around $170.

[Gorath Alpha]

I did forget to confirm that you were stateside, but I suppose that your link to Best Buy was tip-off enough about that.  Here are a pair of HD 5750s, and a GTS250, all priced right at $130, and basically equivilant to one another, which added to that Fortron PSU, totals $175 without the shipping cost.

[PerLindstrom]

Sorry; missed that your PSU may by only 250 W, that´s probably not sufficent.

Please check your sticker, on your PSU

[Chim3ra]

alright thanks guys, for now lol.

I'm running on a 5770, and the game defaults to "Very High" on the graphics detail.  AA is turned off, and I've played fine at 2x, though I haven't tried 4x yet since it looks good enough.  My monitor is a 22" running at 1680x1050, and I run the game at the same resolution.  Other components on mine are a Core i7 920, 6gb (3x2gb) ddr3, wd black edition 1tb 7200rpm 3gb/s hdd, win7 ultimate.  My psu is a corsair 650w.

Will these work? I tried to find some a little cheaper, Thanks again for all the help guys. =D

[Gorath Alpha]

That power supply won't hold up.  It will fail sooner or later, and the odds are not in your favor that it will not be a spectacular show of flashing sparks and billowing, acrid black smoke, as it fries itself and takes assorted components into toast-city along with it!  There are a hundred bad brands, and that is one of them.  There are only about a dozen good brands, and Fortron is among the more budget-price ranged ones from the list.  Sparkle is also frequently priced moderately low. 

HIS is a good brand for video cards, and generally have superior cooling hardware, if you live in a climate that gets very warm, without benefit of air conditioning, that can be very handy to know. 

If you are so worried about a few dollars, don't gamble on crap like that generic one at Tiger Direct ("Diablotek" is a "house brand" at Tiger Direct, like "Rosewill" at Newegg).  Get the best power supply, but go for a lower priced (year older, and faster but cheaper) HD 4850 instead. 

Ditrectron seems to have a lot of sales on Power Supplies, and while I don't consider Cooler Master to be on top of the quality lists, they sell good PSUs made for them by someone like Fortron, and here is one on sale for $38 there:

www.directron.com/rs460pmsra3.html

WOW!  Edited here.  Instead of an HD 4850 for $103, look at an XFX branded HD 4870 for $100, after rebate: 

www.newegg.com/Product/Product.aspx

Here that one is next to the HD 5770:

www.gpureview.com/show_cards.php

They are essentially equal to one another, with the advantage for large screens and higher resolutions going to the older card, with the broader memory bandwidth.

This is the HD 4850, also an HIS branded item, better for games, actually, than an HD 5750, and basically equal to it in every other regard, and only $103:

I had one of those DiabloTek PSUs in a pc and it was bad (lasted a week and i honestly dont believe its 400w rating). I dunno if it was a lemon or just my luck. First thing you will recognize when you get that thing out of the box is how light it is and how flimsy the construction is. To its credit the fan noise was not that bad and its super cheap.

I would find a better one.. but that's just me.

Hi! Do you want to upgrade to 5770 because of DAO? I did that and i regret it a lot because it seems that 5770 isin't  enough to play DAO on max settings and maintain above 40 fps. I have played these games on max settings on 1440x900:  ME 2, resident evil 5, borderlands, batman AA and they ran beautifully but DAO doesn't.

It's ok card but just wanted to share my experience with you before you buy it. It can also be just my computer  because i've seen on youtube when people play it high res. without any problems.

[Gorath Alpha]

I found an HD 4870 at Newegg for $100, after rebate, and it's got double the memory bandwidth, with essentially the same performance otherwise.  I edited it into in my previous warning to the OP to look out for bad behavior from the so-cheap power supply. 

For game playing purposes, it will be 2-3 years before we get beyond Dx10, and a minimum of another year before Dx10 amounts to much of a factor.

Oh okay, so basically don't be cheap with power supplies, and I'll get the one you recommended, as well as the card. Thanks man, but about the direct x11 not being there, when will that be a problem?

Oh yes, I forgot to ask. Is the motherboard good? or will I need to replace that sometime aswell.
