Depending on the power supply quality/brand you should have 400w+. The best PSU manufacturers are Corsair, Antec, OCZ, and Seasonic. Try to get one with higher efficiency and more voltage on the +12v rail.

it will work, that PSU has 28a on its 12v rail. A pc with the ATI 5770 uses 20-22a on the 12v.

FYI, seasonic is a PSU manufacturer & brand. Corsair, Antec and OCZ are just brands.

Thanks to you all. My son and I wanted to build a computer from the ground up but my husband had a fit and insisted on Dell. We opted for a refurb 8100xps i7-860 with a 512mb card figuring we'd upgrade. It has 6mb ram. When I found the power supply was only 350 I was concerned since the manufacturer (Sapphire) says you need 500w. The main thing we wanted was a gaming computer and had decided on the 5770 before hand. Thanks again.

Yes, this dell PSU will run it because of its high amperage -- but you would still be well advised to upgrade the PSU sooner or later. Personally, I would want more of a safety margin than that on what is arguably the most vulnerable part of my computer (and as PSU's age they become less effective)

Second, for the 5770 -- some good deals this week dropping them into the high $120s.

Other thoughts: The 5770 is a good deal--I have one and it performs admirably for the price. If you let us know what model card you have now we can give you an estimate of the performance boost you would see.

Yep the price is coming down since the release of the 6xxx series cards -- Newegg has this Powercolor model on sale through the 10th for $129.99 and a $20 MIR making it $109.99 after Rebate !!

...you run your ATI 5770 on a corsair cx400?? it has 30a on the 12v. the DELL is a Delta design with 28a on the 12v. antec uses it with some better caps for their earthwatts 380w unit. so 2a is your idea of a safety margin?

watts = amber * volts, 28 amber in 12 V trail means it can deliver up 336 watts in the 12 Volts trail only an HD5770 working at 99% 3D (furmark 1.8 test) needs 22a * 12 Volts = 264 watts leaving less than 72 watts to the rest of your devices in your system, a hard disk for example needs 8.5 watts clearly the answer you need “yes it will work” is not that simple. If you planning to overclock the HD5770 the watts consumption will raised.

This is why they recommend bigger watts PSU. The PSU’s are ratted: 80 silver, 80 bronze and 80 gold (energy efficiency above 90%) this is why 80 gold is move expensive. Finally you may need to upgrade your PSU, I recommend for you to find an 80 Bronze Psu.

I will simply be running one card. No overclocking. If I want to get that into it I will definitely be building one which is something my son and I want to do.

This is an exaple how easy it is a system with 4 Gbyte memory to create a load 369 watts (i have 8 ussed only 2.8Gbytes):

http://www.freeuploadimages.org/viewer.php?file=tu4bmvu...

The op spoke about a gaming pc and many frames without a 3 Ghz CPU, 4 Gbytes ram even the best card doesn’t perform right. The truth is a 3.30 Ghz Quad Cpu with the same card can create more FPS than my 3 Ghz Quad, it is our duty to inform him about the possibility of a power failure reboot , system files corrupt, and many problems after that. Some CPUs Q6600 2.4Ghz have 105 watts and a Q6600 3 Ghz 130 watts load if they work at full the risk to give the answer "yes it will work" is really big cause it depends on system configurations. The CPU extra power cable is also in the 12 trail path, some cpus they need 2 4 pins means 24 volts connections on board can you explain how 336 watts will cover the 369 watts needed to duplicate what i did ? or never mind and that..... The HD5770 didn't run in 99% also was overclocked in 950Mhz GPU, 1350 Mhz GDDR5. That was also a lesson some things you read in Toms hardware and the performance they get from the overclock can't be done without a strong PSU the no overclock in you case is a must not an option.

This is why the corporations do recommend high psu for their cards, they don’t gamble with a possible crash in some games, Neither do i.

that is completely incorrect and why you constantly fail to ever post any relevant information. the ati 5770 does not need anywhere near 22a at stress. as proved below, your failure at understand simple PSU makes your posts completely unacceptable and worthless.

ATI 5770 fully stressed in an OC i7 system will not break 300w (or 25a)



this also proved by here as total power conception for the card it self at stress is only 10a

before I even got to the bottom i was already with you bro....
i was thinking that ct1615 was about to go the 'f' off.!!!
then you went ahead a broke out the damn charts..!
calm down bro... lol

i was just going to let him stick his foot in his mouth more and more before I finally shut him up..
he has no clue.


i :love:  charts! how can you argue with 3rd party results. here's one more chart! cause all good things come in threes

from good old Tom's and they use an i7-920 which at stock is 2.66ghz but they over clocked it to 3.8 ghz! it would consume more watts then an OC Q6600.
Test Setup
CPU
Intel Core i7-920 @ 3.8 GHz (20x190), BIOS 1.2625 Volt, 45 nm, Socket 1366 LGA
Motherboard
Asus P6T, PCIe 2.0, ICH10R, 3-Way SLI
Chipset
Intel X58
Memory
Corsair, 3 x 2GB DDR3, TR3X6G1600C8D, 2x570 MHz 8-8-8-20

All power consumption measurements are taken at the wall socket and apply to the entire system, not just the individual card. The 2D value represents an idling system displaying the Windows Vista desktop with Aero deactivated. 3D power consumption is measured with both the graphics card and the CPU under full load. Our power supply is rated at an average efficiency of 82.4 percent by the manufacturer.

the test system above with a factory OC ATI 5770 plus the OC i7-920 CPU comes in at the whopping number of....231w total system power under full load



ATI Radeon HD 5770 OC (1,024MB) 137w-idle / 231w-load / 1 x 6 Pin PCIe

link, card is 16th from the top in the list

I just posted a 369 watts load different configuration, different results do you want to gamble and claim there is no problem and the pc won't even start? Cause ct1615 wrote to one with 300 watts psu and his pc didn't even start with a 420 to send his motherboard to looked out, to other one with 580 watts psu and was having problems with HD5770 (Not enough solid capacitors on board the problem solved with a 2 molex to pci-e) that he has a crappy psu and now what is doing again only he knows. The results you keep on posting is from 1 configuration only in toms hardware charts you will see different results and i did stress my system to show the possibility something like this can happen to any case scenario at 3 Ghz Quad, 4 Gbytes ram.

You know they recommend 600-650 watts to HD5770 and they have good reasons so am i. Also I simplified the selection of a psu to Bronze 80 this time because it can be easily Identified if a psu has it in the web sites. I never gamble stability for me is no1 I do stress the system to extreme before I say go this how I’m I never change.

Another extremely entertaining thread.

@ siren23234, you're system was sold by Dell with the option to upgrade to a 5770, no psu upgrade involved, yes you can run a 5770 in it.

@ mal and ct, the 350w in the newer machines is rated at 25a on the 12v.

Giatrakis you are nothing but a troll. I exposed you as a failure for lacking any PC knowledge and now Ill expose you for the troll you are.

here is the thread about the 580w PSU I was wrong about according to you. "to other one with 580 watts psu and was having problems with HD5770"

http://www.tomshardware.com/forum/forum2.php?config=tom...

there is only one little problem...I never once posting anything in the entire thread!! that makes you a liar!! the guy has a crap 580w PSU with 30a on his 12v rail and had issues, big surprise. the only people in the entire thread are you and him!


the other thread you keep bring up is an OP asking if he can run a GT230 on his HP 300w PSU. The fact is that PSU can and the OP agreed with me (gave me best answer) and not you. you failed to answer his question correctly and he saw it just like everyone else sees. you can keep on trolling but leave me out your inaccurate posts!

I can post over a 400 watts by simply putting my 2 dvd to copy on the fly while is doing what i did before and POSTED for you to see it. I do test the systems to extreme before I give final go and if you get a pc from me it means you can do all the things it meant at the same time without a problem you got that?

i understand English is not a native language for you but you posted

"officially they recommend 600-650 watts they choose to play it safe" followed by "Toms Hardware and if you don’t respect me respect the site. " So I can assume you understand what the lines mean in English. So I will ask for a second time, please post a link to where Tom's recommend 600-650w for an ATI 5770 set up?

here is that question in spanish according to babel fish
fije por favor un acoplamiento a donde dice eso

i'm not gonna search over the net for this one do you understund the part not all the systems have the same configurations and if you want to make a system doing everything at the same time yes there is a possiblity to brake the 400 watts ?

I wrote i did post a 369 watts and you can see it on screen i have the Power consumption under the TASK manager do you have any idea 2 dvds to write on the fly what power consumption do they have?

Whats the point of all these? i tired.
