I'm planning to build a new low-end ish computer . (Under $1000 budget)

I am not sure how much Wattage Power Supply I need for my build.

Here are the components. All in New Zealand Dollars.


CPU - Intel Core i3 2120 3.3GHz Socket 1155 Box - $163.79

MOBO - ASRock B75 Pro3 - $102.59

GPU - Gigabyte Radeon HD7850 OC HDMI Dual-DisplayPort 2GB - $351

RAM - G.Skill Ripjaws X DDR3 PC12800/1600MHz, CL9 8GB 2X4GB - $91

CASE - Antec Three Hundred Two (Black) - $91

HDD - Western Digital Caviar Blue 7200RPM 16MB 500GB - $90

CD/DVD Drive - LG GH24NS90 - $30

So preferably something around $100NZD

All from www.pricespy.co.nz

Okay, I think it is a build that doesn't require much Power, but I heard that the GPU I am planning to use (The HD7850), has quite a high power usage(?)

So which brand/ how much wattage PSU should I be using?

Please give me some options !!

(And comment on the overall build too if possible :d)

Yes I do think that the Antec High Current Gamer would be an excellent choice.

So far without the psu your right at $1000 NZD , and that doesn't leave very much for the psu.

http://pricespy.co.nz/product.php?p=790268 For $112 NZD this might be the best that you can get for price and watts , the Silverstone brand is very good and for what you have you may need between 500w and 600w so it may be best to go with a 600w. You may be able to get a lower watts psu and wth it a lower price but if it ends up too much below $100 I would question the quality.

Thanks for the reply. I've been doing some reworking with the numbers + rethinking the budget a little, and decided that i should spent around $100~$150 for a decent PSU.

Do you think that Antec High Current Gamer HCG-620M 620W for $118.71 is decent?

I think I'm going with either this one or the one you suggested.
The Antec one seems to be quite popular? what do you think

Indeed.. If that one is avaliable, I should go with it... assuming that 550W is enough for my particular build? that is actually the main question I had in mind.

Of course I want to be able to spend as least as possible (Not have too much Wattage left over for no reason I guess?) with the best quality brand which won't fail on me easily.

The 430w reccomended by JK would be enough, the TPN550 provides plenty of room for upgrades

Nothing wrong with that
Having an idea about power consumption usually allows for less expensive reccomendations
I3-2120 maxed out with Prime
http://www.legitreviews.com/article/1650/2/
Under 70 watts

7850 maxed out with Furmark
http://www.techpowerup.com/reviews/AMD/HD_7850_HD_7870/24.html
101 watts

OP's system wouldn't put a 50% load on a 430 watt psu when maxed out with power viruses
