Cooler master GX-450W good?

That will run $60- at newegg. Newegg.com - COOLER MASTER GX 450W RS450-ACAAD3-US 450W ATX12V v2.31 80 PLUS BRONZE Certified Active PFC Power Supply

Ironically for the same price I just picked up a pair of Corsair CX600 model 600w supplies onsale until last wednesday one now in use on the old Antec 900 Vista case running Vista there and the second for a new 7 Pro mini tower case about to be fired up later today. Still waiting the last two items to finish that one up.

As for a 450w model it will mainly depend on how much hardware and what hardwares it will be used for. For a minimum stock case it will meet the minimum requirements. But for any ocing or placing heavy demands on it you may want to consider a larger model supply with more then one rail as well as more connections.

Besides the higher wattage I was also looking at the 40a on the main rail. Plus you have more then one. If you decide to add to the system later or upgrade into a new build where you find you need the larger supply you will already have it for about the same price range.

Cooler Master is another good brand. But each brand also has their different model series at times. The specifications and effeciency are the things to look at mostly however.

Here I simply go above the actual need to some extent so I never reach the 50% mark to start with. The supply itself will typically run cooler along with everything else since it is never pulled on heavily.

Another thing about the CX600 is they seem to run much more quietly then other larger or smaller supplies wattage wise. As fior the other two supplies you want a comparison newegg didn't have the Cooler Master GXX450 instock or simply not found to look the specs over on that one.

The Corsair 430w however is the Builder series and still sees only one main rail but an 80% efficiency rating. The TX series however is the high end line with Corsair however.

The question I would have to add here is where can you buy from? Taking a look at just what the vendor carries will provide the best options for picking one out rather then simply looking at the manufacturer's page only.

There's enough makes and models of supplies to pick from. Some idea of the hardwares you will running on the system will also be a help too since the minimum is 350w for a single HD case with a low end card for the basics.

As far as Channel Well they were also making Antec supplies as well. Zalman, ThermalTake, FSP, Enermax, CoolMax, RaidMax, etc. all see supplies in the 400-500w range to start with.

I used the gx-450 on system i just sold.
My old i7 2600k, Asus P8P67Pro, 8gb, AMD 6770, 1tb 7200 rpm drive, 60gb Ocz SSD.
System runs fine at 4.4ghz, but I clocked it down to stock speeds since I used the stock cooler.

Seems a lot of people over buy a psu, buying waaaaay more psu than they will ever use.
I'm still rocking an Antec 650 with my setup, and I had more things in my pc's than the average person.
Q6600 @ 3Ghz, 8gb ddr2, gtx285, 9600gt, bluray/hd-DVD/DVD-rw, 9 7200rpm drives, 3 90mm fans, 1 120mm fan
With my 3 monitors, 2 large powered speakers, 2 network switches, and some other items, I would pull 390watts from the wall with the CPU and gpu at 100% load. That means the psu is using only 310watts on the dc side, so I've got 340watts of headroom.

My current setup only has 6 hard drives and 2 SSD's, a bluray/hd-DVD/DVD-rw, i7 3770k @ 4.4ghz, corsair h60 with 2 120mm fans, 3 240mm case fans, hd5850 video card. I have a 3.5" hot swap bay so I'll sometimes have 7 hard drives in the machine.

It should work out for you. If you start adding drives and other things in or build a larger case then you may be looking at a larger supply.

The idea of going with a larger supply isn't necessarily having all the extra wattage but the additional power connector for things like twin front intake fans on each drive bay that holds 3 drives as well as the rear, side, and top fans as well as the 3 optical drives now seen lately as well as four sata drives. No Crossfire setup however despite running a dual monitor setup.
