I am in the market for a 600 Watt Power supply and from what i hear corsair is top dog second only to Seasoniq. With that said i have found this dirt cheap 600 watt power supply but i know very little about power supplies accept i know what my system requires for a minimum.

This is the power supply i got my eye on http://www.newegg.com/Product/Product.aspx?Item=N82E16817139028 It has plenty of amperage and wattage for my power Hungary 285 and the price hits the spot as well.

Here is my system
AMD Phenom II X3 710 OC to 3.12GHz 1.42V
6GB Corsair XMS2 800MHz 4-4-4-18 1.85V
EVGA GTX 285 reference
3 SATA II Hard drives 1 IDE Hard drive
OCZ ModXSTReam PRo 600 Watt (12V rail now out of ATX Spec)
about 12 USB Devices

So will that corsair be enough for my rig?

No idea, since the link sends me to an error page.
Here is how you should calculate: Dont look at the W in total, look at how much W is there on the 12V rail (this is the juice to 90% of your pc).
You want as much W on the 12V rail as possible.
Ofc you wont find this info in a store online, but you can google the model of the PSU and then read all about it.

So, lets say you have the GTX 285... you google that first to see how much power it will need (i recommend 3dguru here).

I go there and select the page where they talk about power consumption:


http://www.guru3d.com/articles_pages/bfg_geforce_gtx_285_ocx_review,4.html

So about 400 Wats minimum. You add some extra stuff like a few USBs, etc and it would be about 500W to be safe, more if you plan to add extra hardware later on.

Thats how i do it. After this i add 100W myself to that so that my PSU wont be running at a constant 80-90% when under load, but rather at a 60-70%, reducing heat and noise (important factors for me).

[strike]Link still doesn't post. Can you list the PSU model and the price?[/strike] Now it's working. That has
been a very popular model. It's cheap but not too cheap. Corsair isn't top tier but still good quality.

Seasonic is a step up, and this 620W is only a coupe bucks more.

I cannot afford the FSP one plus i never heard of them so i know nothing about them and I'll be honest that's not acceptable.
Also that silverstone only has 1 year warranty so what does that say about the quality? I mean if they will only honor 1 year then they must think its crap.


And that link does work but i will list the PSU it is a CORSAIR Builder Series CX600 600 watt and the price is 64.99

For a system using a single GeForce GTX 285 graphics card NVIDIA specifies a minimum of a 550 Watt or greater system power supply that has a maximum combined +12 Volt continuous current rating of 40 Amps or greater and that has at least two 6-pin PCI Express supplementary power connectors. I would say that a maximum combined +12 Volt continuous current rating of 33 Amps or greater is more realistic since an NVIDIA reference design GeForce GTX 285 only draws ~18 Amps from the +12V rail(s) when running FurMark stability testing.

Total Power Supply Wattage is NOT the crucial factor in power supply selection!!! Sufficient Total Combined Continuous Power/Current Available on the +12V Rail(s) rated at 45°C - 50°C ambient temperature, is the most critical factor.

Overclocking of the CPU and/or GPU(s) will require an additional increase to the maximum combined +12 Volt continuous current ratings, recommended above, to meet the increase in power required for the overclock. The additional amount required will depend on the magnitude of the overclock being attempted.

The Corsair Builder Series CX600 (SKU# 75-001668 / CP-9020048), with its maximum combined +12 Volt continuous current rating of 46 Amps and with two (6+2)-pin PCI Express supplementary power connectors, is way more than sufficient to power your system configuration with a single GeForce GTX 285 graphics card.

FSP is a great and reputable brand that is a supplier of multiple manufacturer oem's.

That being said the seasonic 620 that was linked would be a step up from the CWT built cx630 for a couple bucks more.
