Help with graphics card/psu settup

[NexRedshirt]

Hi, i currently have a stock hp m8430f pc
Product informationHP Pavilion Media Center m8430f Desktop PC

and i would like to get a new graphics card for it. I have decided to get the nvidea gtx 260 core 216.
Newegg.com - EVGA 896-P3-1255-AR GeForce GTX 260 Core 216 896MB 448-bit GDDR3 PCI Express 2.0 x16 HDCP Ready SLI Supported Video Card - Desktop Graphics / Video Cards

Then i found out that i needed at least 500 watts for it and my current psu only has 300 watts. So im planning on buying this psu-
Newegg.com - Rosewill RP600V2-S-SL-S 600W ATX12V v2.01 SLI Certified CrossFire Ready Power Supply - Power Supplies

First of all will that psu and graphics card work together/with my pc?

And also would it be better for me to buy the gtx 260 core 216 65nm-
Newegg.com - EVGA 896-P3-1265-AR GeForce GTX 260 Core 216 896MB 448-bit GDDR3 PCI Express 2.0 x16 HDCP Ready SLI Supported Video Card - Desktop Graphics / Video Cards

or 55nm
Newegg.com - EVGA 896-P3-1255-AR GeForce GTX 260 Core 216 896MB 448-bit GDDR3 PCI Express 2.0 x16 HDCP Ready SLI Supported Video Card - Desktop Graphics / Video Cards

I read the comparison on this site and since the 55nm is cheeper and comes with a free copy of call of duty world at war i was leaning towards buying that one.

Any help would be greatly appreciated. Thank you.

Hi there, I am not familiar with the Rosewill PSUs so if I were you I would do a quick Google search for PSU reviews but also make sure the PSU has the same dimensions as the PSU you are replacing as I beleive the HPs are kinda small.

The smaller die size on the motherboards should mean a cooler running chip, and the added bonus of CoD:W@W means a pretty good deal. Did you check NCIX on prices too?

A 500W is minimum so you will be happy, a small amount of head room is nice to have.

Ok thanks for that. yeah i checked there site and they are a little more expensive and no free game. so i think ill stick with newegg.

But in terms of compatability, the gtx 260 core 216 should be able to work with that psu? granted i have enough space?

Does anyone else have any more insight on this?

The only thing you need to make sure is that the PSU has the PCI-E power cables you would need to run the card.

Supplementary Power Connectors 6-pin x2

Looks like the PSU is SLI certified so it probably has 4 of the 6 pin connectors.

It says PCI-E Connectors 2 x 6Pin.
So it should work then, right?

EDIT: sorry for double post...

Hmm, are you set on the Rosewill because of the price or because it will fit your case? You may be better off with a better quality PSU... from some of the reviews I have looked at the Rosewills are not that great. I'm not going to say that are bad, I don't have one nor have I looked really far into it, but some of the things I have seen indicate that there are better choices out there, but at a cost, of course.

Newegg.ca - CORSAIR CMPSU-550VX 550W ATX12V V2.2 SLI Ready CrossFire Ready 80 PLUS Certified Active PFC Compatible with Core i7 Power Supply - Power Supplies

and a $20 USD rebate... consider it perhaps?

Like I said, do a good search for reviews on the PSUs before you make a final choice.

O.o imho sell the hp and build ur own

Price is my main factor atm. I know the less expensive the lower the quality but that rosewill seemed decent for the price considering it costs 112$ off of their site and only 60 off of newegg.
Also now i am very confused...
what is the difference between
Newegg.com - EVGA 896-P3-1255-AR GeForce GTX 260 Core 216 896MB 448-bit GDDR3 PCI Express 2.0 x16 HDCP Ready SLI Supported Video Card - Desktop Graphics / Video Cards
and
Newegg.com - XFX GX260NADFF GeForce GTX 260 Core 216 896MB 448-bit GDDR3 PCI Express 2.0 x16 HDCP Ready SLI Supported Video Card - Desktop Graphics / Video Cards

if the only difference is manufacturer, then which do you suggest i buy?
Which is the better company to buy a graphics card from?
Considering that the xfx one comes with 2 games and its only 10$ more.

And why is the xfx gtx 260 not listed on there site?
