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 around  1350~1400w




Input Voltage 110V ,  upper right value (KW) is power consumption ,


Video1 Vga Default





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 around  1700~1800w .



Video2  2200watts 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...!

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

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
