Help a newbie out on a cheap PSU.

[andyli625]

Hi,

This is my first legitimate build; my others were prebuilts that are modified .

Proposed specs:

CPU: AMD Phenom II X4 965 BE with stock cooler and Heatsink. (I will try to overclock as high as possible with stock until I can afford to get aftermarket parts)

Motherboard:GIGABYTE GA-970A-UD3 (http://www.newegg.com/Product/Product.aspx?Item=N82E16813128519)

GPU: Gigabyte 7750 (I will, in the future get either a 7750 or a 7770 to be crossfired with)(http://www.amazon.com/gp/product/B0079XWPEK/ref=oh_details_o06_s00_i00)

Ram:G.SKILL Ripjaws X Series 8GB (http://www.newegg.com/Product/Product.aspx?Item=N82E16820231428)

HDD: 500gb Seagate Momentous XT (boot drive) / 1TB Seagate Barracuda/ and 160gb Hitachi.*

Case: Raidmax Viper (http://www.newegg.com/Product/Product.aspx?Item=N82E16811156274)

*Salvaged parts

I would like to pay as little as possible for my PSU without blowing my pc up lol. Currently budget is around 50 bucks.

Thanks guys!

Cx 430 it's a great PSU. It will suffice you.

Cx 430 can deliver a bit mre than 430 W .

A little calc

965 Be = 125 +15W (OC) =140
Hd 7750 = 49 W on peak
Ram = 16 W
Hdd = 15w
Dvd = 15-25W

Total=245W So u will be set

the Cx 430 isnt design to go even near 430w if the majority of the consumption is from the gpu and cpu. 12v wise, it goes up to 256w. You dont get into units that have 12v rails = the label wattage until at least the 65$ish mark

28a x 12v =336w albeit i made a mathmetical error on my last post(i knew something felt off) lower end units dont output the labeled wattage. lets use one of corsairs mid range models as an example

430-336=94 watt difference

corsair tx 650w

+3.3V@30A, +5V@30A, +12V@54A, -12V@0.8A, +5VSB@3.0A

54a x 12v = 648w

650-648=2 watt differennce

If u can read all the pages of that review sir !

It delivered 369W on 12V rail GPU + PSU.

Thats why i recomended it. It a great PSU for its price .One of the greatest budget build PSU and on newegg can be get for 35$.

The OP consumes 245W and the CX 430 has 369. So 369-245=124W more ? That is ENOUGH .

Cheers

the problem is that load testing allows for the tester to load the rails appropriately, and is not indicative to real life performance. ALSO I never said the Cx 430 wasnt enough, I was just refuting that its not designed to run past its labeled wattage as a computer system has no way of spiting all of the loads on the different rails evenly

Go to the overlock page testing -.-. It passed its blabeled power. 336 with 369 . Thats a lot for the CX

refer to your original statement

Cx 430 can deliver a bit mre than 430 W .

thats what im fixing. I have nothing against agreeing with the 3xx statement. but saying more than 430w is not indicative of real life usage.

Go for the cheapest good quality PSU (Corsair CX430 suggested above is more than enough) and spend the extra cash for a 7770, 650 Ti, or a 7850.

 

[iam2thecrowe]

antec have the best quality/value lower end psu's imo, especially for a gaming pc that has a lot of strain on the 12v, they deliver. and with good efficiency,

 

[prototype18]

I would say both Vp 450 and Cx 430 are good unit's.

I just recommended the CX 430 cuz iv been building PC lately and Corsair never failed me.

If u can check review's they have the same power wattage @12V. So whatever u choose will be ok for your configuration .

Thank all of you guys! You guys are awesome! I ended up going with a Corsair CX600. It was only $30 after MIR! thanks again guys!
