CroosFire Power Consumption?

[machjaghjolu]

Hi all,

I am about to receive a new config with an AMD phenom X4 955, a Sapphire HD5770 Vapor-X, 2x2GB Corsair DDR3, 1 HDD and 1 DVD burner, all that with an Advance Triolux 8909 480W, and my question is..........

Will I be able to improve my system by Crossfiring with a second 5770 in the fuure without getting a more powerful Power supply? Or will I need a 650W?

Thanks.

E saluti a tutti.

Doubtful, that sounds like a pretty crappy power supply. Maybe if it was an antec or corsair, but probably not that. But of course get a second opinion cause I could be wrong.

With 480W,no you can't CF dual HD5770 on that PSU, better get higher PSU (650W or more) if you want to CF dual HD5770.

I never heard Advance Triolux 8909 before, so get trusted brands like Corsair, Antec, Seasonic, OCZ, PCP&C, SilverStone.

Thanks to all,

I'll get a 650W then...

Actually a quality 450W from name brands can do crossfire fine, no need for 650W really.

Dual HD5770 on 450W (Quality) PSU?
Are you sure?

Well, 650W is good for long term, in case the OP want to get higher cards...

 

[Timop]

The 5770s uses 80W each, while the 955 uses 125W, add in another 50W for the board, fans and HDDs, his load power comsumption would be less than 335W.

Yes, you're quite right.
But Higher PSU should be good for safety and longer term. 450W PSU is just too low to run dual card.
Well, that's just me.

Here's an ocz 600w psu + HD 5770 vapor-X you might be interested in.

although you could br right, i wouldn't risk it..... the PSU would definitely be strained running 2 cards and I bet it would lead to frequent BSOD's

 

[machjaghjolu]

Well, except the BSOD's, do you think there is any hardware hazard?

 

[Glacier]

I agree with the 650w PSU. The power supply is the most important part of the PC, don't risk using a cheap one.

 

[Timop]

Less wattage does not equal cheapness, a Corsair/Seasonic 450W is still high-quality.

Getting a 650W is just wasting money, he will have 100W of overhead even with a 450W, anymore becomes pretty redundant.

 

[borisof007]

I don't think it's a waste of money at all. Buying new parts should never be about the now, it should always be about what you might do in the future. Yeah he might overbuy for the now, but if he gets more in the future then he's set right?

 

[Timop]

Yes and no. I mean if he strains his budget for a 650W when he could get away fine with a 450W isn't very smart. But if he wants a 650W anyways then get it, its not bad having too much power.

However, eventhough PSUs is the part of the build that lasts a while, technology do get better with time for less.
Just think about 3 years ago how crazy it would be getting a 650W 80+ Gold modular PSU for $130.
