Thinking of going modular...

[haas1mj]

My current setup is below and i'm wondering if the current power supply I have is going to be enough if I start overclocking my video card. I am also adding two front intake fans and would like to focus on my cable management to get better airflow. Thanks.

Intel Core i5-2500K running at 4.5Ghz
Cooler Master Hyper 212 Plus
ASRock Z77 PRO3
16Gb G.SKILL Ripjaws Series DDR3 1600
MSI TwinFrozr 2Gb GTX 670 PE
Antec NEO ECO 520C 520W Continuous Power ATX12V
Antec 300 Case
ASUS VH242H Black 23.6" 5ms HDMI Full 1080P Widescreen LCD

Your system as is consumes only around 250W during gaming so there is absolutely nothing to worry about. 520C is rated for 480W on the +12V.

Improving cable management will have no noticeable effect on airflow unless your cables are literally blocking the intake fans. If you still want to improve cable management, going modular with only a 520W unit won't really help, you're already using most of the cables. Buying a better case would help.

From what i've been reading on here I was thinking that I should be okay but just wanted to make sure. The sales people at Micro Center kept saying I needed a bigger one to power my 670. Which to me didnt make much sense because this generation of cards is more power efficient than the last. Thanks for the solid advice as usual!

Micro Center has a bunch of Diabloteks and Inlands in stock and they need to move that inventory. Those PSUs can't deliver their stated wattage and they need to avoid having people complaining and returning the goods since their supposed 750 W PSU system crashing and doing weird stuff because the PSU is actually incapable of delivering that much power to their rigs. Every time you return something, the credit card company takes a chunk out of the company's money

Yes, current PSU more than sufficient. No, going modular won't help airflow.

This one.

ZAP im so upset hahaha. That deal is discontinued they have no more in stock that was a crazy deal thanks for the heads up. I was thinking of grabbing a corsair 600w 80plus bronze cert. Thanks once again for the response.

Well, the CX500 is an option for $50AR. Less of a crazy deal, but still a solid unit at a fair price.

Yea i have a CX430 but im not even going to do first boot with that. I just feel that it wont be enough. The plan is to go CX500 or CX600. Ive had a couple people tell me that the 430w will be fine i just dont trust it

At stock, the CX430 is mostly certainly enough, even with Bulldozer's poor power consumption control. Only thing is, you need a molex to 6 pin adapter to make it work with a 7870

Total system power consumption was 226 watts with the FX-4100 and a 6950(6xxx means older, which means more power hungry. x9xx means higher level), and this is "at the wall". After multiplying "at the wall" readings by the efficiency percentage, that nets you what is actually delivered to the motherboard/CPU, and that value is what determines how close to the PSU's max wattage you are.

Using the 226 watt value in the review, you multiply it with 87% (HX850 is 80 Plus Gold certified, so it is safe to assume that percentage), and you get 196 watts of power consumed by the components.

Maybe i will go first boot with it then and test it under full load. Thanks for the reply. i kind of hijacked the OP thread sorry

I agree, spend the money on something you will notice, like a new video card, SSD, or maybe a CPU.
