I have Gembird psu-6 PSUhttp://www.gembird.cn/default.aspx?op=products&op2=item&id=2596
And dont know if the hd 7770 will work on it.
(as idk what that 6 pin rail is?)
Will my psu run it?
Please help me & sorry for my english!
For a system
using a single Radeon HD 7770
graphics card AMD specifies a minimum of a 500 Watt or greater power supply. The power supply should also have a combined +12 Volt continuous current rating of 23 Amps or greater
and have at least one 6-pin PCI Express supplementary power connector
Total Power Supply Wattage is NOT the crucial factor in power supply selection!!! Total Combined Continuous Power/Current Available on the +12V Rail(s) is the most important factor.
The Gembird CCC-PSU6 500W Power supply
, with its +12 Volt continuous current rating of 17 Amps
and with NO 6-pin PCI Express supplementary power connector
, is insufficient
to power your system configuration with a single Radeon HD 7770
. Judging by that PSU's specifications it is based on an old design that emphasizes power on the +5V and +3.3V rails (i.e. 56% of that PSU's total capacity). Its single +12V rail only supplies up to 41% of that PSU's total power capacity.
If you would have purchased the more modern Gembird CCC-PSU6X
instead, it would have worked, because it has a PCI Express power connector and a combined +12 Volt continuous current rating of more than 28 Amps.
