Can a 450w PSU handle this?

Charlise · May 30, 2015

Specs:

INTEL PENTIUM G3220
ASUS B85M-G
KINGSTON 2×4GB DDR3 1333MHz
SAPPHIRE DUAL-X R9 270 2GB DDR5 256BIT
WESTERN 1TB BLUE

the PSU is this:

ANTEC VP450

I've heard that it's quite a decent PSU for the price. Other choices are:

CORSAIR VS450
HEC COUGAR SL-500

So, can this PSU handle.the system just fine? I've read on the Sapphire site that the recommended PSU is 500w, so am I in danger with the ANTEC VP450?

It will probably work but your cutting it a bit close. The 270 draws 254watts at full load. so that leaves about 200 watts for the rest of the system so that should be enough but your cutting it quite close. Dont overclock or anything.

Dunlop - that 254w your stating is wrong.
The 270 is a 150w card absolute max - its all it can draw - 75w through the card slot & 75w from the 6 pin cable.

A 450w will run it fine - I would honestly take the vs450 over that antec though .

Seasonic 520w S12ii will be a great choice

madmatt30 :

Oh yes i apologize i read it wrong the whole system consumed 254watts at load i though it had a 6pin and 8pin.

Here is a good article on the power consumption of the 270: http://www.guru3d.com/articles-pages/amd-radeon-r9-270-review,8.html

@ madmatt30- So you are saying CWT over FSP? Not disagreeing, just asking.

madmatt30 · May 30, 2015

Archaic - no mate fsp & cwt are generally on a par.
Just out of those 2 models the corsair vs is the better unit.
The antec has no opc circuitry & a crappy 360w 12v rail - that's a jumped up 400w max IMO.
I'm surprised antec put their name to it in all honesty
