PSU Help

[Mikey9980]

Ive been looking around for new a new PSU annd ive been wondering would the 450W Corsair VX Series PSU beable to cope with my system.

EVGA GTX 260
1 x DVD/RW
2 x Samsung F1 Hard Drives
AMD Phenom 720 OC'd to 3.5GHz

Thats about it really, including Motherboard, RAM, Couple of fans and sound card.

Please help.

It should in theory, however the VX450 to my knowledge only has a single 6pin PCI-E power cable for the GFX card, the GTX260 needs two, you could use an adaptor cable though.

I would opt for the VX550 just for the extra head room

See I would but it's well out my budget.

If you could recommend any other PSUs under £60 that would be great, thanks.

Oh and also the GTX 260 needs an amp rating of 36amperes and the 450W VX only has an amp rating of 33amperes.

Plug your system into our PSU Finder:

I have and it comes up with the VX 450W, but it doesn't make any sense...why would it come up with that PSU because it only has 33amps on the 12v and the GTX 260 needs a minimum of 36amps.

[LuckyNV]

Is that from the Nvidia site?

That includes the entire system

GTX alone uses only 136W peak (about 11A on the +12V rail)

The recommendation you see for 36amps is for an entire system. Think about it, 36amps at 12v is 432w. There is no way a single GPU, not even a dual core 295 will ever come anywhere close to consuming 432w. The current PCI-e spec is capped at 300w for a single card, whether dual core or single core.

[Mikey9980]

Ok thanks, I think I understand now.

All depends on the rest of your system spec aswell.

I wouldnt use a dual rail 450W PSU (is the corsair dual or single?) PSU with a 260.

[Mikey9980]

Lol thats what I thought.

Cheers

It's a single rail PSU. If you can sneak it into the budget or find a good sale, the VX-550 is still a better idea to give you a bit more headroom.

Its OK I ended up buying a http://www.novatech.co.uk/novatech/s....html?OCZ-M500 for £54.

Its modular and it was a low price so I bought it.
