Title: Which PSU [XFX 650/XFX 850] should go in which build AMD 1055T/Intel 2500k]?
Post by: soarwitheagles on February 13, 2011, 09:11:10 am

Hi everyone!

I recently received a great deal on a couple of XFX's PSU's.  I am trying to understand which PSU would best suit build.

Here's the PSU's I just purchased:

XFX 650 Modular
XFX 850 Modular

Here's my two latest builds:

Intel 2500K/Gigabyte P67A-UD3
AMD 1055T/Gigabyte 890XA-UD3

Both systems will have the exact same peripherals/hardware:

8 GB or RAM
1 Agility 2 SSD
1 Galaxy GTX 460 GC
2 Western Digital 2TB HD's
CM Storm Sniper with all fan slots filled
Corsair's H70's
ASUS DVD drive

Ok, now the million dollar question:

What would be the best placement of the PSU's and why?
Maybe a better of way of saying it would be: Which system will need the extra power and why?

Thanks,

Soar

To be honest Soar there isn't much difference between the two systems and I would suggest putting the larger PSU into which ever system you intend to overclock more. Either PSU should be enough to run either system so unless you are planning any future upgrades it wouldn't really matter.

Theoretically, the 2500k has lower power consumption than the 1055t. The difference seems to be quite noticeable, too. I think I'd place the 650W with the Intel CPU.

In the end, just like DM said, both of these PSUs are more than enough. The 850W is actually bordering on overkill if you don't plan to add anything in the future.

Here's a link to power consumption tests by guru3d:

P.S. Please tell me that you're going to overclock that 2500k ;). It just seems like such a waste to have it running stock when it should do 4,5 Ghz easily. Maybe even 5 Ghz but that'd require some effort to reach.  In the end, you can get at least 1 Ghz over stock values.
