Connect3d HD5670 power supply requirements

Hello all!

I have a question regarding the power requirements of the above mentioned card. The manufacturer's website (link below) recommends a 450W psu with pci-e connector, while others (sapphire, gigabyte) recommend a 400W psu without pci-e connector. Does anyone know how many Amps does it need on the 12V rail?

My psu is Silverpower sp-ss400 (400W) and has 17A+17A in two 12V rails. Maximum combined 360W for the 12V rails. Would that be ok? It also has two pci-e connectors. In my system I have an amd 5050e cpu (45W tdp), a sata2 hdd (7200rpm) and a sata dvdrw which i almost never use.

The connect3d website has nothing more to say, not even a manual to download! Does anyone have experience with the specific card or with the company whatsoever?

The reason I am thinking of buying this card is because I found it on a store for 50euro (it is on the shop's window, no box etc but with 2year guarantee) which I consider a good price.

Thnx in advance!

my advice to you is that the graphics card immediately purchase: attach a try how it works. if it runs out of power simply buy more power. 500W and that's it

nenix, thnx for your reply

I hyad already purchased the card a few days after my post. Before that, I emailed connect3d and amd and asked about the requirements of the card, but conect3d gave no reply, and amd said that the info I am requesting is not available to end users!

Anyway I bought the card and it works ok in the system specified above.

thnx for taking a look
