780W HiperPower HPU-4M780

post #1 of 13
Thread Starter 
Is this card up to the following job.
780W HiperPower HPU-4M780

I have used the PSU calcuator page thing online...

It said i need 697W to run the following...
Opteron 180 @ 2911 Mhz @ 1.4v
ASrock Dual Sata (1x 20 Pin + 1x 4pin)
2GB RAM
3x Sata Har Drives
2x DVD RW Drives
FANS - 2x 120mm - 1x PCI - 2x 80mm - CPU Fan
2x ATI 3870 X2


I know my board is not SLi or Crossfire enabled...
JUst wanting to get a PSU that i can grow into IF i get a new MB in the future...

I know the PSU comes with a 1x 24 Pin, 1x 4pin P4 and 1x 8pin P8...
i have been told they will fit my current board as they just overhang the connections on my board...

its just wither the PSU is physically capable of powering everything well as reading rails and voltages is not my fortay.....lol

I would recommend the Corsair 750TX. 60A on a single rail. Plenty of power for dual 3870x2. The best part about the PSU is that it comes with 4 6+2 pin PCIE power connectors, perfect for teh 3870x2.

Also, If you think to crossfire 3870x2 with that CPU....don't do it.
The CPU will be bottlenecking the hell out of the 3870x2s.

Exactly what I was going to say, I would stick with one 3870x2 and get a quad than get another.

Yes, a 750w(in your case 780w) should handle two 3870x2 fine. Don't go lower than 750w w/ two 3870x2's.

The hiper is good!...
and i can get it today!...lol

last question...
Bear in mind i am only using a 19" wide screen monitor @ 1440x900...
what bennifts in performance would i get in running 2x 3870 X2's?
or...
for a screen that size V the cost...stick with one 3870 X2?

(i would not be running 2x 3870 X2's on current setup - i would be getting a new MB and CPU - thats well in future though...)

i had a hiper, i just replaced it with the 750tx.

hiper is a good psu, however, they use sub par capacitors. the 750tx uses high quality japanese capacitors.
