Upgrading my PSU

[KieraDK]

I recently bought a new graphics card that is a significant upgrade to my current, only to find out that my current PSU doesn't have any power cables to provide the card with what it needs.

Old Graphics Card - http://www.nvidia.com/object/product...ce_210_us.html
PC - http://h40059.www4.hp.com/uk/homedes...erience=direct

Because my PC is store bought I can't find my PSU anywhere on the internet. I do know that it's HP and only outputs about 300w whereas the new card needs a minimum of 400w.
I'm just wondering whether different PSU's have different connectors and whether I need to adjust my purchase to match what connections I have on my motherboard?

This may sound like a stupid question but bear in mind that I'm not completely literate with computers. I do know how to put it together and stuff though...

Also, any recommendations for a new PSU? I live in Europe, if that makes any difference

The GTS 450 only requires a single 6-pin PCIe power connector. If you have two free Molex 4-pin power connectors, you can buy a simple y-adapter cable. You can also get by on a 300W PSU if it's actually rated honestly.

Maybe, but this is a premade HP. That 300W PSU very likely doesn't have the amperage required for any kind of modern video card.

Anything with 20A+ on 12v lanes , FSP 500W/Chieftec 500W should do it and they are quite cheap.

Antec quality, 80+ bronze, 430w

$45 on newegg, limited time

can't beat that with a stick

there's also a 500w version

They're green colored, and not modular

From the outside it LOOKS like a standard atx case so any atx PSU should work. A good brand 400 or 500 watt unit will provide plenty of juice.

Can you take a picture of the PSU and post it here so that we can see if it is a standard atx unit?

No cables anywhere, they're all being used

Don't know whether mine is ATX or not

I took a picture of the insides, but I didn't know what to specifically take one of. If it's wrong, I'll post another!

Looks like a standard ATX PSU to me.
And god damn, these HP's have bad cable management..

It is a standard ATX PSU and a cheap ass one at that. Any atx psu should work wonderfully.

This will be plenty for your build: http://www.newegg.com/Product/Produc...82E16817371029

Remember, the 400 watt recommendation is only there to compensate for super cheap units that can't even pull near their rated wattage. A well built unit will have huge safety margins and can operate at maximum power throughout their designated lifetime. Not that your system will pull anywhere near 400 watts, the GTS 450 is a pretty efficient card (106 watt TDP according to Nvidia site).

Thanks for the advice, but I can't actually order them. Doesn't ship to England.

Any others?
