Will a hd 7850 run on a 450 w psu?

psu - corsair vs 450
fx6100@3.6ghz
8gb kingston 1333mhz
Gigabyte ga78lmtusb3 motherboard
3x 120 mm led fans

Yes, easily. A 7850 pulls hardly any power.

 

[amuffin]

Yes.

Especially considering you have a pretty decent/reliable PSU like the VS450!

 

[sidsatmis]

also will the fx 6100 bottleneck the 7850 ??

 

[sidsatmis]

the amd website says that the 7850 requires a minimum 500 w psu ????

Check +12v a ratings of psu. Remember your psu is not 80+ certified.

Usually vs450 comes from some asian countries.if it has +12 good rating then it is fine.

You haven't got the strongest CPU on the planet but it wont bottleneck a 7850. AMD reccomends a 500w because people usually see that it requires that and then go out and buy a 10$ 500w PSU that will explode if you get it anywhere near that, so at its actual requirement its safe. On your system its unlikely you'll pull more than 250w or so.

The Corsair VS 450 is made by CWT like most Corsair units. Although not 80 Plus certified it produces 34 amps on the 12v rail for 408 watts on the 12v rail. The new 80 Plus Bronze version of the 430CX makes 32a/382w on the 12v rail. That makes the VS 450 more powerful even though it's less efficient. It is plenty of power for an HD 7850.

so all in all im fine with a 7850 on my rig right ??

 

[Deleted member 217926]

Yep.

 

[ASHISH65]

Better open the case and tell +12v ratings dude

Then doubt the RealhardtechX database. The older dual rail version has been discontinued for quite some time. He almost certainly has the newer version with an AMD FX processor.

Even then the older version had 30a/360w on the12v rail. Still plenty for an HD 7850.

Had it a few months.

Not that it will matter soon except as a "legacy" badge. You heard a date on the switchover Muffin? I thought it was supposed to be at the end of January. Looks like they missed.

 

[sidsatmis]

it says 34 a on +12v rail and below that it says 408w :*
