is coolmax a good psu brand

Im looking at psu's and way thinking of this model. Wanted to know if it was a good brand.

COOLMAX CUG-950B 950W ATX12V V.2.2 Power Supply

 

this is $150 with a $20 MIR. If anyone has a recommendation on a psu for like $150 with 900 plus watts plz post it.

 

HELL NO.
Avoid.

You don't need 900W, nobody does.
Post your PC specs and I'll recommend you a good PSU.

Note: Even quad core PCs with two graphics cards can run on a good 500W PSU, but a cheap 800W PSU will fall apart with something half as powerful - there's far more to PSUs than the wattage.

 

Go with Sam on this one. I bought a good Corsair 650W PSU for $90 because I knew it was overkill. I'm powering an 8800GT video card, an OC'd quad core CPU (both 4 wire 12V straight to the mobo), 4 hard drives and 2 ODD and the thing doesnt even break a sweat.

 

Indeed, there's very little a 650W TX can't power, with the exception of triple SLI or Quad crossfire.

 

at amazon.com the 650TX is only $95 and the 550HX is $86. wouldnt it be worth it to spend the extra 7 dollars to get the 650?

uncanny, i agree with the rest, 550HX should be enough, let alone a 650TX or the 950W one you originally posted.

 

There's no 550HX, only a 550VX (single rail) or 520HX (modular)

 

hey srry im back,

I figured id check with you guys didnt want a psu falling apart .
My second choice was this

A million times better than the Coolmax, an excellent PSU. Still overkill for most PCs though, that PSU can run two HD4870 graphics cards and an overclocked quad core processor with acres of room to spare. What are you running?

 

im going to be using crossfire or sli as im still deciding then the x48 mobo or 780i, Q6600 quad cpu, 8gb or RAM, 750gb hd and a dvd/cd writer and rom.

 

Crossfire. Do not use SLI, the motherboards for it are, to quote Abuzar "a $300 kick in the balls".

I recommend a Gigabyte X48-DS4 and two Radeon HD4870 graphics cards.

 

how long before im not a newbie lol i hate posting every 3 mins.

also what do you think of modular psu's?

 

I have no objection to them. Assuming you don't need to use every cable, they are useful for helping reduce clutter. They are, however, overpriced for what they are, and Corsair have yet to offer a modular power supply that's compatible with the HD4870 combination. For help in that department, look to Zalman (ZM-850-HP) or the Enermax Modu82 units. They are a LOT more expensive than the 750TX though.

 

dont know if i can afford 2 4870 unless the price goes down a bit but i was thinking of 2 4850's.

 

two 4850s is fine enough, you can use the Corsair HX520 or 620 PSU with those, or the VX550 or TX650.

 

TY everyone, once again sam thx alot your always very helpful.

 

sorry if im thread jacking but i also plan on getting the corsair power supply, the 550VX, and is the 650TX better? its only a few dollars more. what are the differenced between single rail and modular (advantages?)?

 

Not the same thing. You either mean single rail vs multi rail, or non-modular vs modular.

The 'rails' on a power supply usually imply the 12V rails, so a multi-rail power supply mean the PSU has multiple different segments that produce the 12V output, so a very high load on one will not impare the other. However, a well built PSU will not suffer these disadvantage, so it has no real purpose.

Modular power supplies on the other hand are very handy - they have power connectors you can remove so you only need to have the cables you will actually use in your case. Non-modular units, especially the powerful ones, have piles of cable that a lot of people won't use.


The 650TX may only be a few dollars more dragnandy, but will you ever use that much power? A PC with two HD4850 graphics cards in crossfire, an overclocked quad core processor and four hard disk drives at peak full load will only use 400-450W. For this system, I would get the TX 650 for extra 'headroom', but if you won't ever run anything as power-hungry as this, then the VX550 is perfectly fine.

 

since its just a 'few' dollars more, it seems like i might get it. and i understand your point sammorris. so is there a way to like tone down the power that the psu uses? so it will like give out the same ammount of power as a 550VX, but when i upgrade i can change it. you know, to be more energy efficient and such.

 

Power supplies will only ever put out as much power as you're using. Just because you have a 550W PSU doesn't mean it will use that much power, it just means that's the most it can produce.
