Hey, I'm trying to order all my parts and the PSU I was going to get sold out. I need to pick a replacement really quick. Any opinions GREATLY welcome. Here's my setup, according to the Antec PSU calculator, I need 438w, but I'm planning on overclocking in the future.

Antec Nine Hundred Two Ver3.0 Black Gaming Case
Samsung 1TB Spinpoint F3 SATA II 7200RPM 32M
LG H22NS50 SATA 22X+- Super Multi DVDR Black with Software
G Skill 8G(2x4G) DDR3 1600Mhz PC12800 RL 9-9-9-24(CL9D-8GBRL)
Gigabyte GTX560Ti OC 1G GDDR5 PCIE DualLink DVI
Intel Core i7 2600K Processor LGA1155 3.4GHz CPU
ASRock Z68 Extreme4 Z68 4xDDR3 3*PCIex16 GBL RAID DVI HDMI DS
Intel X25-M 80GB 2.5" MLC G2 Solid State Hard Drive

Here's a couple options in my price range.

or
CoolerMaster 650W GX 80+

You have to consider a Corsair 650TX in that price range. That Coolermaster you listed is a good one too.

both are good ill through in corsair tx 650 v2 and the OCZ ModXStream Pro 700W because its Modular
trade the i7 for the i5 2500k
get a sata III hdd
and spend the extra on a gtx 570 or a 6970

Okay, PSUs are wayyy over my head. First off, I'm sorry to say I don't even know what modular is. Each of these is right around my price range, though. So what are the main advantages to the modular? Or the others?


Antec ATX TruePower 650W

OCZ ModXstream Pro 700W modular PSU

Corsair TX-650 650W ATX Power

CoolerMaster 600W Silent Pro Modular (most expensive, but also best reviewed)

Okay, I had time to read up on modular PSUs. So basically it just lets you pick the cables you need and take out the ones you don't to reduce clutter, right? That sounds good, and I see the benefits from it. I don't think its worth spending another $50+ on, but any of the PSUs mentioned above would work. I'm just wondering, though, if the CoolerMaster 600W would be enough if I ever decide to overclock a bit. It seems to be a much more reliable PSU than the OCZ.

Modular or not is mostly a non issue.
You will be using most of the leads from a properly sized psu.
If you have a small case,perhaps.
On a quality psu, there should be no issue with leads coming loose.

As to sizing, your GTX560ti is the predominate power consumer. It requires two 6 pin pci-e 75w power connectors.
Most good 500w units will have that. A 650w unit will be able to power a GTX580.
If you contemplate future sli of the GTX560, then most 750w units will have 4 power leads which should be sufficient.

I would probably consider Antec and Corsair to be the best brands mentioned.

Other good ones would be Seasonic, PC P&C, and XFX if they are available.

Don't skimp on psu quality. A cheap unit that fails can cause your other parts to go too.

Foe what it is worth, the extra $100 spent on a 2600K over a 2500K is not worth it for a gamer.
Both will OC to about the same levels, and the extra hyperthreads are not used in hardly any games.
You will do better to use that $100 elsewhere. A GTX570? or a larger ssd?

The X25-M is an older generation ssd. If you are getting a good price on it, then you will be happy with it.
But the 320 series is a newer generation, has a better warranty, and is a bit faster. It usually sells at the same price.
