Hello one of my friends wants to upgrade from a 8800GT, done some searching and i really like the performance with the 5750 crossfire, and for the price. Im not sure if he could handle it.

His computer.

8800GT
Phenom 4x 9600 @ 2.3 ghz
4GB DDR2 800
790x motherboard.


Im running with the same powersupply as he is running with an ATI 4870, and Phenom 8400 x3 @ 2,52 ghz and 3GB ddr 800 runs great.


Im not really sure if it will handle it. Guess not?

If it is a quality unit it should not be a problem.

We would need to know the brand and model of the PSU to tell you for sure.

I cannot find any "good" information, every thing is in german. and there are not alot of sites with it. anyways the PSU is called "TITAN LC6560T"


This is the best information i found about the power supply. this is just translated on "translate.google.com" from german to english lol..


PC power supply / Series: LC Power Pro-Line Series / Power: 560 Watt / currents: +3.3 V (35A), +12 V1 (18A), +12 V2 (18A), +5 V (40 A) / Form Factor ATX12V 2.2 / Cooling: active / Number of fans: 1 / Automatic Fan Control / Power Factor Correction: active / motherboard power connectors: ATX12V 2.x (24-pin) ATX12V (20 Pin), ATX12V (4 pin) / S-ATA Connections: 2 / 3.5 inch drive connector: 2 / 5.25 drive connector: 7 / PCI-Express connectors (6-pin): 2 / Features: ATI CrossFire Ready, nVidia SLi Ready

I've never heard of the brand but if those numbers for the +12v rails are anything close to reality then you should be fine to crossfire HD5750s. FYI his processor at 2.3 is going to bottleneck 2 HD5750 so upgrading that should be the next thing to do. If it is a 790 chipset then likely it can handle AM3 chips.

Yeah. its an AM2+ is cable of the new AMD x6 cores too. But for gaming.. the old phenom II 965 would be great.

Its cable of ocing abit i guess he allready has a new cpu cooler.

The 955 is actually usually the better buy. They are the same processor just with different stock speeds. If you are going to OC anyway(you should) there's no reason to spend more for the 965. Try to get one with the newer C3 stepping.

I know.. I dont think he is going to buy a new CPU, he might but the GPUs and see how the cpu will run it. oc it abit maybe.... (:

At $260 going rate for twin 5750's, it doesn't appear to be the best choice in this price category:

use this to see if PSU is big enuff

Given the ATI published specs, you may have a warranty issue if ya blow somethin up

http://www.amd.com/us/products/desktop/graphics/ati-rad...

ATI Radeon™ HD 5750 System Requirements
450 Watt or greater power supply with one 75W 6-pin PCI Express® power connectors recommended (600 Watt and two 6-pin connectors for ATI CrossFireX™ technology in dual mode)

The published specs are entirely useless as usual. The HD5750 doesn't even use its power connector(stays under 75w during normal usage.) It only tends to go above that during stress testing and then it tops out at around 80w.

YackNaylorPE.

Im from Faroe island, and the pricese are not near anything like newegg, or any other american website. and the Publihed specs doesnt really count, it depends more on if its a "Quality" or "Not Quality".... as far as i know. (:

My problem is. I never even head the name "TITAN" on a PSU and i dont know if its quality or not, and im not really sure how to see if its a good PSU or not 0.o
