HD5770 power consumption

[yonyz]

The following are my PC specs:

Corsair VX450W
Intel Q6600
2GB 667Mhz
GIGABYTE GA-P35C-DS3R

If I add an HD5770 card, will the PSU hold it?

you dont say what your CPU is but i would guess you will be okay.

the test system here has a overclocked core i7 and it never broke 300w under full load.

enjoy.

Sorry, I absolutely forgot about it. Please see my updated original post.

BTW, I should probably note that I was told that my PSU will hold an HD4850, and the TechSpot review shows no big difference in power consumption of the HD4850 and HD5770 cards. It will be OK, then?

All of Corsairs PSU below 700 watts are made by Seasonic so that PSU will be fully stable under or near full load and a Radeon HD5770 won't be pushing that PC anywhere near to full load anyway.

The PSU can delivery just under 400 watts under full load in the 12v rail (33amps X 12V) and the maximum draw of a Q6600/HD5770 will be around about 250 watts so you still have 80 odd watts left to play with.

The actual power consumption of that card is less than 100w so I think you are ok unless the voltage on the 12v rail is already low (less than 11.35) then a new psu is recommended. However if the volts are lets say 11.8 then you are ok so what is your current card?

My current card is HD2400XT with 256MB. By Sapphire.

No. Not true.

For example, the Corsair 550VX is manufactured by CWT

A non-OC'ed HD 5770 consumes just over 61w for typical gaming:

Using FurMark to completely stress the HD 5770 brings up power consumption to 81w:

Hi yonyz,

You have no worries at all with that PSU my friend it will easilly power a HD5770.
Never mind a 4850 it will power a 4870 without breaking sweat.

I had one of those my self so I would go ahead and get the new card then see how the rig runs.
