Cpu: Intel Core i5 650 @ 3.20 ghz and upto 3.33 ghz with turbo boost

Ram: 4GB 1333MHZ (upgrade ram later)

Psu: 320 watts for my cpu and an (((((external FSP Booster X5 450watts independent/supplementary power supply)))))) for the "AMD Radeon R9 280X" Only.

will this be enough power?

320 WATTS FOR THE REST OF THE COMPUTER AND A SEPERATE 450W FOR THE GRAPHICS CARD ONLY WHICH IS ((Sapphire AMD Radeon R9 280X Vapor-X OC 3GB))

I did this because my pc is an oem pc HP WHICH MEANS I CANT upgrade my power supply.

After reading reviews I saw that a single Sapphire Radeon R9 280X Vapor-X CAN CONSUME 466.2 WATTS.

More about : psu 320w 450w

You are good to go your power supply is more than enough for your rig, your whole system wont use more than 500-550w and 450w dedicated only to the gpu is more than enough for any card on earth, but make sure that your PSUs are certified ones

Wait your trying to run TWO PSUs just because the computer is OEM? That is rubbish, high risk, and NO you can't just dedicate a second power to the card to 'add' power to the computer, that isn't how it works. If you read the description the add on power is to assist with TWO CARD rigs (SLI / Crossfire) not a cheap work around because your not wanting to change out your OEM powersupply like everyone does. This product listed would be helpful to add to the power the two cards are already getting (at least 750W already - see below) from the MOBO, but there isn't enough power for the add on connections DIRECT from the PSU. That is how the device would 'fill the gap'.

The card sits and is FIRST powered by the slot, which requires a level of power output equal the the minumum requirements of the INSTALLED PSU to the MOBO. Secondary power inputted to the card is a direct draw feed to energize and power the multiple cores of multiple card we see now on the higher end videocards. That said per http://www.sapphiretech.com/presentation/product/produc... states "750 Watt Power Supply is required.
1000WattPower Supply is recommended for CrossFireX™ System." so you need to replace IN YOUR COMPUTER the powersupply with a 750W like everyone else, if not a KILOWATT (1000w) if you plan to Overclock or add a second card later.

If your case is small and you want to upgrade the system to include a high end video card, then you need to upgrade the case as well (plenty of us do that too) with the PSU, then move all the hardware into the new case. IF your PSU just sucks in the computer, then just replace it with a new one instead of trying to 'short cut' . REMEMBER: ONE SMALL FOOT DRAG across the floor then touching the CPU/GPU will FRY the card, what do you think monkeying with the powersupply instead of 'doing it right the first time' would do?

IT IS NOT ANOTHER PSU IT IS JUST A DEDEICATED PSU FOR THE GPU AND DOESNOT CONNECT TO THE MOBO IT IS JUST CONNECTED TO ANOTHER POWER PLUG.
JUST SEE THE CUSTOMER REVIEWS AND IMAGES IN AMAZON.

You will be fine mate...That's more than enough, even if you overclock that gpu to the point no one has, your card won't use more than 300w, and 350w for the rest of the system, that's more than enough, and yes dedicated psus are different, it is not like running two psus

Yes I DID, and you did not read my answer, so let me try it another way.

THERE IS NO " DEDEICATED PSU FOR THE GPU"*****

If you open any NON-GAMER computer, you will NOT see a DIRECT PSU->GPU connection, because BY DESIGN all powering of ADD-ON cards to the motherboard are powered through the slots of the motherboard. These NEW DUAL slot cards (which are really two video cards with MULTIPLE CPU/Memory through a single slot connection) require ADDITIONAL (not dedicated power) power, and thus the added PSU>GPU connection, which required THE CHANGE OUT of your OEM PSU like everyone else.

This product your citing, in the product description "SLI AND CROSSFIRE UPGRADE, HASSLE-FREE! The BoosterX 5 is an easy add-on 5.25" supplementary power supply module designed solely to boost power support for your latest demanding SLI and CrossFire platforms."
NOTICE: "add-on, supplementaty, boost" NOT DEDICATED SOLE POWER.

Because if you install the 750W power supply REQUIRED (see system requirements http://www.sapphiretech.com/presentation/product/produc...) and wanted to ADD a second card (SLI/Crossfire), you couldn't you need 1000W to run both. THEN you would go and BUY the FSP Group 450 WATT Power Supply SLI Certified, Crossfire upgrade with QUAD PCI-Express output and Active PFC (Booster X5) to support the SECOND CARD power needs. It does NOT WORK AS A SOLE POWER SUPPLY for the GPU.

It is a sole power supply because it is connected to the main power supply with a molex so when the main psu wakes up the Dedicated PSU wakes up too.In the pictures if you see the computer used is a HP ELITE 8200 which has 320-watt power supply and then he added a booster to power his GTX 660ti using one 8-pin and one 6-pin which are power connectors while the motherboard only dilevers 75-WATTS to the gpu which is not enough to power it. Beside it says the BOOSTER X5 is a supplementary/ Independant so it does not need the main PSU.

Plz read the reviews and see the pics.

Okay let's back up a step please to clarify. Yes I understand what your saying, let us narrow this discussion down since your bent on the review there as the total accuracy for YOUR intention (if A+B Works then A+Z should also work).
As you noted " HP ELITE 8200 which has 320-watt power supply and then he added a booster to power his GTX 660ti using one 8-pin and one 6-pin which are power connectors while the motherboard only dilevers 75-WATTS to the gpu which is not enough to power it" and "Plz read the reviews"

The reviews encompass the 660 your mentioning which requires 450W (http://www.geforce.com/hardware/desktop-gpus/geforce-gt...), there is a Quadro FX 5800 which needs only 189W (http://www.nvidia.com/object/product_quadro_fx_5800_us....) then there is the HD 7950 which needs 500W (http://www.amd.com/US/PRODUCTS/DESKTOP/GRAPHICS/7000/79...).

Taking your math 450W 660 - 320W needs 120W more
189W FX5800 - 320W needs 0 More
500W 7950 - 320W needs 180W more.

Your Sapphire AMD Radeon R9 280X Vapor-X OC 3GB needs 750W to 1000W - 320W needs 430W to 68W more (depending how much you overclock and such which INCREASES power consumption).

Do you see the significant difference here? I understand you want to get this killer card and have 'very little left over' to get a proper PSU, but ANY Gamer will tell you NEVER cheap on the power, and your significantly not powering the card here (this isn't just a little more power needed). The NORMAL solution is to REPLACE the PSU outright, you have NOT identified how your OEM HP can't have the PSU replaced? Have you just written down ALL the connections needed and just looked for PSUs with that MANY connections INSTEAD OF looking for THAT model HP computer 'replacement PSU' ? I personally found that solution works alot better.

Secondly the problem with a 'non-OEM rated HP PSU' is it may not 'fit' that specific size case, normally someone getting a new PSU gets a combo PSU/Case then just moves the hardware into the new rig (simpliest easiest solutions). Why is this also not a solution?

Buy a $20 case and a Corsair CX430, job done.
