Upgrading to 460GTX do you think my mothboard and PSU cope!

[naz]

My new specs:

E6750 @ 2.66Ghz
Asus P5B motherboard 965P with 1x PCIEX16 slot
2gb DDR2 800 Ram
ASUS 8800Gt 512mb
PSI 550 WATT PSU

+12V - 24A MAX :is this enough power or should I consider getting a GTX 450
+5V - 40A MAX

Will be playing Shogun Total War 2 and playing Blu-Ray ISO's

The PSI 550 PSU might be a problem. Look for a card with similar power use to your 8800GT.

you should be fine I reckon. my system was very similar and i went from 8800GT to the GTX 460 without any problems.

 

[SeeknDestroy]

you should be fine with your psu, the 460 is quite energy firendly

That sounds like a cheap and nasty PSU.

A quick calculation suggests 262W minimum with 312W recommended (assuming a 768MB 460).

For a 1GB 460 it's 281W minimum with 331W recommended.

With your 8800GT it's 226W minimum with 276W recommended.

As most of this is on the 12V rail, and you only have 288W on that rail, I think you're going to struggle.

A 460 also needs two 6 pin power connectors from the PSU.

You may get away with it but you're cetainly going to be pushing that PSU to its limits.

I was hoping to get the 1GB GTX460, I have 1 spare molex connector, can that be used to connect a 6pin power connector using an adapter. Obviously I'm already using the other on my 8800gt. I'll have to disconnect my internal DVD drive and use my spare external DVD-RW drive. I hope that does'nt sound too stupid, but I also have 3 samung 1.5tb drives in here too drawing power.

Excluding the DVD-RW and adding 3 1.5TB drives (assumed 5900RPM) you're looking at 287W minimum with 337W recommended.

For a molex to 6 pin adapter you need 2 molex plugs.

Overall I'd say you're going to struggle.

The power supply you have provides no more 12V power than a decent 300W unit.

Nvidia recommend a minimum 450W PSU for the 460.

That would be a decent 450W PSU which will provide around 33A on the 12V rail.
