Windows 7: Cooler master GX-450W good?

I plan to buy new PSU for my build I5-2400+GTS450
Is this cooler master good?
anyone has it and can tell is it reliable? Is one 12v rail good or bad.. i was reading some reviews and still am confused

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.

as newegg dont ship to my location, price on newegg is irrelevant.
i dont need 600w im fine with good 400W. power usage is only around 50% load.
is corsair builder series v2 better than coolermaster GX?
for example corsair cx430v2 vs cooler master GX450
witch one has better quality, reliability... because they both have enough power.

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.

Do you have access to XFX, Corsair, Antec, or Seasonic brands in the 400 to 500 watt range?

I would not get overly concerned about the one 12 volt rail issue.

I think that particular Coolermaster GX series is made by Seventeam and would probably not be my first choice.

I think the Corsair builder series V2 is manufactured by Channel Well--and would not be my first choice either.

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 think cooler master Model RS-450-ACAA-D3 is made by Enhance Electronics
I have access to Corsair, Antec, Seasonic
most Seasonic is too expensive for me S12II 430W seasonic price is around 2 times more than that of GX450w cooler master.
From corsair in my price range is only builder series like CX430 V2
antec is a bit expesive.
YES i want to buy budget PSU that is reliable.. i dont do extreme gaming and my W requirement is relatively low.. max draw should never exceed 350W

another thing there is some active PFC PSU models that have bad compatibility with UPS, because i need to use ups, i want PSU that has no issues with ups.

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.

I dont do overcloking i dont see the need for it.. my cpu has enough power its better to add ssd to increase speed, because HDD is the slowest part.
after reading this review Cooler Master GX 450 W Power Supply Review | Hardware Secrets
bought Cooler master Gx-450w.. will report if it works good

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.
