HP Pavilion 400Y elite compatibility?

[Sapphire88]

I was looking to upgrade my HP's motherboard,graphics card and PSU for better gaming performance but am wondering if it will work? I was looking to get:

Corsair Builder Series CX600 600W ATX12V v2.3 80 Plus Bronze Certified Active PFC Power Supply

ASRock Z77 Extreme4 LGA 1155 Intel Z77 HDMI SATA 6Gb/s USB 3.0 ATX Intel Motherboard

SAPPHIRE Radeon HD 6870 1GB 256-bit GDDR5 PCI Express 2.1 x16 HDCP Ready CrossFireX Support Video Card (100314-3L )


Here are my specs on my computer now:

HP PAVILION ELITE HPE 400Y Desktop

N-Alvorix-RS880-uATX

AMD Phenom II X4 945

8 GB of Memory

ATI Radeon 5450

Intergrated ALC888S-VD Audio

1 TB Hard Drive

15 in 1 Memory Card Reader

Mid Size ATX Computer Case

300W Power Supply

Is my computer going to support the upgrade's I want, and if not what are some other components I should look at for good gaming performance?

From the looks of it, you should just upgrade your PSU and GPU

The Phenom II X4 945 is still very capable today and you shouldn't need to upgrade it at all! I would recommend swapping out the HD5450 for a Radeon HD7870 or GTX660; with that said, your entire system will only need a 500w PSU (Corsair CX500V2 is the optimal choice for price/wattage/quality)

That should save you a bit of cash while giving you significantly more performance to put into an entire system upgrade sometime next year (if you desire to do so). With Haswell coming out in a few months, I would highly advise holding off until then

Ive noticed that the corsair is a atx12v. Will that work in something that is just atx?

The Corsair PSU I have recommended is a standard ATX format PSU, this will work with ANY other component that is also in this ATX format
