Calculating power requirements

Delarado · 3 Nov 2013 at 12:16

Guys,

How do I work out what PSU I'll need in my system?

Or more accurately, how do I work out if my current PSU is up to the job?

I have an Antec 850w high current pro modular PSU running:

Intel i7 3770
HD7770 x 2
5x 3.5 inch 7200 SATA HDD
1x 2.5 inch SDD 256gb
48gb RAM
TV Card
2x5.25 inch CD rom

Will that be enough?

Thats plenty.

A good 650W PSU would run that spec.

Yep, Your PSU will be ample!

Can I ask why do you have 48GB of RAM ?

sorry its nto 48gb, its 32gb... I didn't actually build this machine, but my home machine has similar levels.

I get lots of RAM because I do a LOT of stuff with VMware, I ALWAYS have at least two winodws 7 VM's running, and am often running 5-6 virtual machines at the same time! It really helps

Ah I see. I thought 48 was a funny number.
