430W Corasir or 600W Cooler Master for i5-2500k build?

post #1 of 22
Thread Starter 
Components:
CPU: i5-2500K
Mobo: Gigabyte GA-Z68A-D3H-B3
RAM: Gskill Ripjaws X Series 4x4GB DDR3 1600
SSD: OCZ Vertex 3
CPU Fan: Mugen 3 or similar, any suggestions for small OC
Case: Lian Li PC-K57W
Video: Onboard for now, add ATI 6870 later

I am choosing between two power supplies.

I am leaning towards the 430 W because it is much cheaper and corsair quality. I don't know if 430W will be enough if I end up adding the video card. I plan to OC to 4.5 max (limited by gigabyte board). The 600W seems like a good option for a cheap modular psu. I fear that 600W will be overkill and I will be using unnecessary power/running very inefficient.

OCZ has a modular 500W but it is ATX12V V2.2, not v2.3 (is that a big deal?):

Thank you!

I would really not go below 1000 Watts in todays market, I reccomend something from Cougar, mine has 6 12V+ rails, and damn is it powerful. You have to think about future upgrades when building a computer.

430W is enough for a single card and for $25 after MIR, it's a pretty good deal.

EDIT:

Lol at the 1000w for SLI 460. Anyways OP if you plan on running crossfire you might wana invest in a higher wattage PSU, a quality 650w should power CF 6870 with headroom.

Someone sig this.

OT: Get the 600W one.

1000W is definitely overkill. You don't need anything near that much. Between the two, the Corsair is a superior power supply. However, if you can spend a bit more, you might want to go for a bit more juice. Consult the OCN Reccomended Power Supply list. Just search it.

The way I see it, it's better to have wattage to spare than to not have enough...I'd get the 600w

I would not pick a Cooler Master PSU, they're mostly failures. Check this thread for more info.

That 430w is able to handle that PC just fine, as according to this calculator.

I'd check the recommended PSU thread to decide what PSU to get for your machine. Any quality 400-500w PSU can handle that machine without problems.

1kw PSU is way too overkill, unless you go trifire.

great thanks for all the input. I guess I will get the quality 430W as opposed to the less quality 600W which gives me more room for upgrades.

Any suggestions on a CPU fan that will allow for a light overclock. Want to bundle the two in an order so I can use $10 off $50. I was looking at Mugen 3 or Hyper 212+.

OT: Alternatively I could just order an extra case fan to exceed 50. The Lian Li PC-K57W is on the way. I can't find anywhere on what size extra case fan to put in it! Any ideas??? I looks as though it takes an additional 140mm in the front. How many pin connector do I need? Sorry I've never added fans before
