balltillifall · Jun 29, 2010

My question is when i hook up my pow supp willl i only have to attach one of it's cords to the graphics card and thats it? and is it easy to install a pow supp? dont know too much about comps fyi, i've watched some videos though and it doesnt seem too complicated.

They have a tendency to edit the cables out of those pictures, probably think it makes it look prettier or something. And yes you will have to connect one of the 6 pin PCI-E connectors to the 5770.

As for changing the power supply this should help,

won't matter whether it is mounted in the top or the bottom of the case, there will still only be the four screws as shown in the tutorial holding it in. Just make sure to disconnect all the cables from the motherboard, hard drives, etc before removing the screws.

I just wanted to add take your time, put a little effort into routing your cables. It will help with air flow and keeping your system cooler in the long run. Fabe

Yes and can be. Installing a psu can be tricky depending on the case. An HP case is a modified matx case, which means you won't have a lot of room in the case to maneuver. Be ginger when switching out the psu. However, I am worried about the graphics card not fitting. The 5770 is a large card and space is at a premium. Also, study how the current psu is connected to the motherboard. The new one will have to have the same connections.

I rebuilt an HP and encountered these space issues.

FYI: Fill out your system specs on your profile once you're done.

Lot of room? Somewhat of an understatement. I managed to find this,

balltillifall if you haven't added a second optical drive you can stuff the extra cables in the empty drive bay under the one that is there.

When I changed my last PSU, I first made sure that I tagged all the cables on the new PSU according to the connections from the old PSU. Just find the matching plug on the new PSU and attach a self sticky label with a description of where it belongs. That helps you to put some order into all those cables because there are probably a lot more on your new PSU than on your old one.
Switching the PSU itself is not a big deal, but getting some order into all the cables (including the ones that are not being used) is another matter. Make sure you use enough cable ties and keep them away of any moving parts (e.g. the cooling fans).

Here is how my place looked like:

I like understatements. The HP I rebuilt was worse and that was because I had to supply parts for it - pratically half of the computer.

Cable ties are great to use.

im more worried about the box part of the pow supp fitting in not the cords, anyone know if it will fit for sure or?

kodi · Jul 1, 2010

I would not recommend that power supply it has a total of 400 amps on the two +12volt rails which means it is not an efficient power supply.
If it fails it could take other parts with it (Motherboard,Ram)save your self some money and buy a good brand power supply, on the page you linked to there is a seasonic 600w that is a very good brand.

out of 41 reviews it got a 4 out of 5, id be using this graphics card

u sure i shouldnt get it?

I have to agree with Kodi. The PSU you selected may not be the best option. I used an Antec PSU for my HP Pavilion and it fit perfectly. The one I used is currently not available but it was similar to this one: Newegg.com - Antec EarthWatts Green EA-430D Green 430W Continuous power ATX12V v2.3 / EPS 12V 80 PLUS BRONZE Certified Active PFC Power Supply
For a few bucks more you can also get a 550 Watt box.

No good. Efficiency is only 65% - but it should be at least 80%. Why do you insist on those rinky dink units where there are a lot of excellent units on the market. The PSU can give you a lot of trouble if you settle for a cheap deal.

The power supply is the most overlooked but the most vital of ALL the components in your PC, without a Decent power supply the you beaut vid card/cpu etc will not function at its peak.
I have posted a link to information that was compiled by a Team of Experts its long but gives all the information you need to make the right choice.
LINK HERE

CarlTR6 · Jul 1, 2010

Good link, Kodi; thank you. I am looking, too

Wishmaster · Jul 1, 2010

Believe it or, a Corsair 450W is a better power supply than the 600W one linked.

There have been some other good Power Supplys suggested, but I would highly recommend Corsairs PSUS. Either the 450W or a 550W would be more than enough.

The 400W (32A) Corsair would likely be enough for your system & that card as well.

I have 1 PC here that runs a E8400, 4GB RAM & a 512MB HD 3870 GPu on the 400W Corsair without issues.
Not all 400W PSUs can do that however. And thats the point everyone is making here.

Wattage in itself doesnt mean that much. Its all about the 12V rail amperage, and effeciency.

Whichever recommendation you decide to choose, bottom line, get a quality PSU.

Good link Kodi!

im just a major comp noob who really appreciates your guys help

Wishmaster · Jul 1, 2010

So long as its a quality PSU, you really do not need 700+ watts.

In most cases 550-650 of a quality supply will power mid-higher end setups.

Mind you, highend multiple GPUs may need more juice, but for a single card this is really all you need.
