Antec HCP1200w with GTX580 4way SLI OC'ed, Monster 2200w input !
Nvidia GTX580 already launched 3weeks . Lots people care about the power consumption of it .Nvidia also did some OCP tweak inside of the card . So u will not get the real power consumption of it unless u release the OCP function.
So i tried the real power consumption of GTX580 4way SLI on Antec HCP1200w. And i have also recorded videos , it easily shows the " input "watts from wall .
Testing hardware :
PSU : Antec HCP1200W (Retail Version)
CPU : 980x
VGA : MSI GTX580 4way SLI
MB : Gigabyte X58 UD9
HDD : Adata S599 100GB
RAM : Adata XPG + 2200 CL8 2GBx3
Cooler : Antec Kuhler Flow + Formula 7 Paste

Before we do 4way SLI on Gigabyte X58 UD9 , u have to plug-in the molex 4pin input of the VGA extra power .
Or u will burn ur 24pin connector on mobo .
It is big problem of 4way SLI . Bcz 4 cards pull a lots from 24pin 12V input .
And it only has one 12v+ wired on mobo 24pin connector . When u are benching the 3Dmark program or Gaming .
The current which goes through 24pin connector will reach 20~25A . Actually the safe value of it is around 7~10A .
That is why lots people burn their rigs with 4way SLI even 3way SLI recently.

Using Prime95 and Furmark for GPU & CPU Full loading test .
Let's see video of the real input power consumption of GTX580 4way SLI of whole system.
It is around 1500~1600w from wall . Before unlocking OCP , it is around 1200~1300w .
The efficiency of HCP1200 is around 89% with such loading .
So output watt is around1350~1400w
Input Voltage 110V ,upper right value (KW) is power consumption ,

i like to push hardwares to extremity. So i add the VGA voltage to 1.1 vcore
Core speed to 820 Mhz . Totally 2200w continue input loading done .
The efficiency of HCP1200 is around 81% with such loading .
So output watt is around1700~1800w .
Video22200watts input
This HCP1200 is mass production version (retail one) . 1200 watts output is recommanded value .
Seems that it can endure higher output watts .
So , Maybe we can fry something with the heat from 4 pcs GTX580 again , ROLF ! 不會燒PSU嗎.....
1200W輸出2200W，該說好還是不好.......?
過功率保護的點不知道在哪裡 這樣還能測得過嗎 = = 只看4張[金卡]..
MB 已經快看不到了...! 不會燒PSU嗎.....

OPP Peak 瞬間保護到2700w ,會斷掉重開機
超過額定負載太久 ,零件溫度會過溫 , OTP會直接觸動了
我測了 ,變壓器不會炸 ,OTP會先保護:)... 多測幾次試試看
說不一定還是會照爆不誤XD ANTEC SIGNATURE系列的轉生 而且還更強 也是猛將一名了 回復 5# nickshih
1200W可以當2200W用真的好
恐怖==
超恐怖
大大可以考慮七盟有一顆2000W的 @@太兇悍了4張...
