Will this PSU fit in my computer?

Specs: Windows 7 home premium
I have a hp pavilion a4327c with a 250 watt power supply which is an ATX-250-12z and I was wondering if this (link below) PSU is compatible and will work well?

It should physically fit in the space but I am not sure cooler master is a great psu.

I am not sure what you need in the way of connections and what have you. You may want to research that a bit.

Not only that Newegg has the PSU your looking at $10 cheaper.

I agree with likelystory but why do u need another psu?

I am looking to upgrade my graphics card to a nvidia geforce gtx 460 and it is recommended to have a 450 watt psu

And what am I supposed to look for in terms of the connections? Is it the 24 or 20 pin connectors or something because this site shows the cables that my original psu has.


Or this one:


I don't know which is right because I'm not very computer savvy.

Most modern day psu's have a 24 pin connector. if you only need 20, you just unhook the 4 extras.

Your model appears to be a standard width mini tower.

A standard sized power supply should fit in your case fine.

Standard (PS/2) power supply size - 86mm high, 150mm wide, 140mm deep, or 3 3/8" h x 5 7/8" w x 5 1/2" d , or very close to that, though the depth can be more or less for some PSs.

Measure your present power supply.

Don't buy an el-cheapo PS.
See response 3 in this:

Your power supply must have at least the minimum capacity required to support a system with the graphics card you are using installed, or the max graphics card you might install in the future.
(Onboard video - video built into the mboard - IS NOT A CARD ! )
If that info is not in the ad for the video card, you can go to the video card maker's web site and look up the specs for the model - often under system requirements - the minimum PS wattage, and, more important, the minimum amperage the PS must supply at 12v is stated. If you don't find that, any card with the same video chipset including any letters after the model number has very similar minimum PS requirements. Some power supplies have two or more +12v ratings - in that case, add those ratings to determine the total +12v current capacity.

E.g. for the geforce gtx 460 - 450 watts minimum,
with +12 Volt current rating of 24 Amps minimum
- Two available 6-pin PCI-E power dongles

If you're a gamer...
In most if not all cases, the max capacity rating of the PS is an intermittent rating. It's recommended that you do not load your PS to any more that 80% of that rating if you are going to be using something that puts a constant load on it, such as playing a recent game for hours on end. In that case, you multiply the min capacity stated for the system with the particular video chipset on the card by 1.25 to find the min. capacity of the PS you should get.

E.g. for the geforce gtx 460 - 450 x 1.25 = 562.5 watts minimum, with +12 Volt current rating of 30 Amps minimum

The PS should have:

"Two available 6-pin PCI-E power dongles" (connectors on the PS wiring)
for the two 6 pin power sockets on the card.

Although, some graphics cards come with (a) wiring adapter(s) you can connect to any PS for that purpose.
