Is a 430 Watt Power Supply Enough for This Job?

Hey guys, I'm new to the website and I got a quick question to ask you all.

I recently bought these products:

PNY VCGGTS2501XPB GeForce GTS 250 1GB

COOLER
MASTER Hyper 212

G.SKILL 4GB (2 x 2GB) 240-Pin DDR3 SDRAM DDR3 1333 (PC3 10666)

ASUS M4A78T-E AM3

AMD Phenom II X4 955 Black Edition 3.2GHz Socket AM3 125W Quad-Core Processor

I... was wondering if a 430 watt power supply is good enough to run these items. I calculated the amount of power that all my items might consume ( at http://extreme.outervision.com/PSUEngine ) and it totaled up to be around 405 watts. Now my question is, IF i should stick with this power supply or get a new one in the near future?

Also, the total amount of watts consumed includes fans, hard drives, dvd drives, usb connections, etc.

depends who's 430W unit it is, if the outvision calculator told you that it will pull about 405 then you are going to want to go for atleast a 500W unit as most of your power gets pulled from the 12V rail and most units under 450 or 500 wont be able to provide up to 400 on the 12V rail, my EA500 only provides 408 so i doubt you will have a 430 that is strong enough to handle it without a problem.

Thanks for the advice, do you have a suggestion of a power supply that is around 500Watts or more and is under $50?

$50 after MIR, but you really dont want to skimp on your PSU or you can run into issues with low quality components which can kill a system.


I will most likely get this PSU that you have recommended, hopefully it will run all my parts :) 

I have also found this one http://www.newegg.com/Product/Product.aspx?Item=N82E168... , cheaper...I'm not sure, I'll keep looking.

Thanks for the advice!

the little red switch on the back means it doesnt have Active PFC which all newer designs have, it will also only provide up to 29A(348W) on the 12V rails and isnt 80+ certified so it isnt very efficient and isnt guaranteed not to explode at 100% load.

Two very important things to look for in a PSU, atleast 80+ standard certificiation, and active PFC, it restricts you to newer designs that have been tested and passed at full load.

Understood ;)  , so basically the power supply that you have recommended will perform all my desired needs?
