http://goo.gl/D1xSYS

I need a new PSU so that i can get a new GPU. My current PSU is too small.

I'd have to see the interior of the case

The HP specs page states ATX form factor on the power supply.
You should not have problems changing it to the new power supply.
Both are ATX spec.

The new psu you're considering is the same physical size as your current one, so it will fit. (the dimensions listed on that Amazon page must be for the box it comes in, since the manufacturer site lists smaller dimensions: http://www.corsair.com/us/power-supply-units/cx-series-psu/cx-series-cx500m-modular-atx-power-supply-500-watt-80-plus-bronze-certified-modular-psu.html)

Unolocogringo :

How can i tell if it is ATX spec?

babachicken · Nov 9, 2013

MauveCloud :

the corsair one says it is 150mm x 86mm x 140mm
but my computer's psu says 150mm x 140mm x 86mm

i'm sorry if this is a stupid question but i am a bit new to the topic

The specs for your computer don't clearly indicate which is height, which is width, and which is length, but any ATX psu will have height of 86mm (3.4 inches) and a width of 150mm (5.9 inches). The length is what can vary - 140mm is the minimum afaik, and good psus of that size go up to 700W; at 160mm you could get up to 1200W if you needed it (you shouldn't, since iirc, even sli titans can run on a good 850W psu) - ref http://www.overclock.net/t/1256282/short-psu-list-atx-psus-that-are-160mm-or-shorter-small-case-friendly
Support for 160mm-length psus is fairly common as well. If you start looking at psus 180mm or longer, then it becomes worthwhile to double-check whether your case can support it. Sometime recently I was curious about the longest atx psu ever made, and came across this one: http://www.legitreviews.com/sneak-peak-ultra-products-2000w-atx-power-supply_436 - 10.25 inches long (probably 260mm), so I don't think there are many cases that would fit it.

Thanks for the information, what could be the best CHEAP 500w PSU.

Are you willing to use a mail-in rebate? If so, there's a good deal on the Antec Neo Eco 520W here at the moment:

If not, here's a Silverstone Strider ST50F-ES for a little cheaper than the CX500M but still good:

I don't think there are any cheaper choices I'd trust.

MauveCloud :

i can only but from amazon because i got 50$ for it. i saw a cooler master one for about 45 dollars. i think cooler master has a good rep.

babachicken :

Only a few CM power supply's are good. Mostly their new high wattage models.

This is a list from best to worst. If a model is not on the list consult with the forum before purchasing.
http://www.eggxpert.com/forums/thread/323050.aspx
A lot of cheap power supply manufactures rate the product at max output. Which is only for a few milliseconds.
Better brands rate theirs at continuous output.
For example the CM 525watt extreme on Amazon is one of these "Cheap" models.
It will put out about 400-410 watts before shutting down.

Can you send me a picture of the interior of your case?

Unolocogringo · Nov 9, 2013

What GPU are you considering? You may not need a 500watt power supply for it.
A good quality 430watt power supply is better than a cheap 500watt model.

babachicken · Nov 9, 2013

Unolocogringo :

so you think my computer along with some usb things connected and a new GPU. 430w will be enough?

Unolocogringo · Nov 10, 2013

Depends on the GPU.
I have a 650TI running on a 430w for folding just fine.
And a 7800gt running on a 350 watt power supply.
It is not so much the wattage rating. But the AMPS or WATTS available on the 12v line. AND if it is rated at max output or continuous output.
A lot of cheap power supplys have a lot of their wattage on the 3.3 and 5 volt rails. With very little on the 12v rail.
Modern computers pull all of their power for the GPU and CPU from the 12v rail. Very little is used from the 3.3 and 5v unless you have a ton of hard drives and USB devices.

I want to get this http://goo.gl/zvoxTM

Unolocogringo · Nov 10, 2013

http://www.amazon.com/Corsair-Builder-Watt-EPS%C2%A0-CX430/dp/B0092ML1SC/ref=sr_1_1?s=pc&ie=UTF8&qid=1384107215&sr=1-1 For that video card the Corsair CX430 watt will be overkill. And leave room for minor upgrades.

babachicken · Nov 10, 2013

Unolocogringo :

wait so the 430 cx is too much wattage?

Unolocogringo · Nov 10, 2013

Your computer will only draw the power it needs.
It is best to run a power supply around 75-80% of its maximum output for best efficiency. It also keeps power supply temps lower and extends its life.
you could get by with a quality 350 watt unit . Quality being the important factor. A cheap 350watt unit would fail in a short amount of time or a really cheapo unit would switch off every time you were playing a game from overheating.
The Corsair 430 watt would allow you to upgrade to a 7790 or GTX 650 video card without problems.
The 5 to 8 dollars you would save buying a cheaper power supply is not worth the chance of it frying and killing other parts when it does.

Unolocogringo :

is the 7790 oc ->http://goo.gl/GOwqVJ any good when paired up with my system?

babachicken · Nov 10, 2013

could i run dual graphics?

Unolocogringo · Nov 10, 2013

The 7790 is a good bit faster than the 7770. It is GCN based chip. And would be a good entry level card for your system.
Dual Graphics and Crossfire of low end cards is not a wise choice. Too many problems with micro stutter and game support. If a game does not have good Crossfire support ,it can be slower with dual/crossfire systems. It is always better to get a single more powerful card than two low end cards.
The only real exception to this is mating two high end cards for triple monitor, or high resolution gaming where one high end card would not be sufficient.

A few games do have good dual card support ,but not many. In those particular games you would see a good benefit. but most games would not benefit from it.
This article explains it fairly well.

so would the MSI one be a good choice?

I just got a corsair cx 430, will that be enough to power this card along with my pc? http://goo.gl/nZOjEg <- this is the card

Unolocogringo · Nov 12, 2013

You should be good to go.
the cx430 has32amps or 384 watts available on the 12v rail. Your computer will be in the 260-330 watt range while gaming.
Good choices hope you enjoy your games now.
