Firstly hello everyone and thanks for any help which may be given.

Quite a simple question im guessing i have recently purchased a PNY GTX295 which is great but when it comes to powering it its a little confusing.....
I went to the pc shop and they sugested this
http://www.microdirect.co.uk/Home/Pr...l-850W-80--PSU

I baught it on there sayso but looking now it does actuall give the 680w minimum power needed, But the card demands a current rating of 46amp. Which i dont think this card gives, i think from what i can tell with my very very limited knolage it gives a current amp of 36.
Could anyone confirm weather this is right or not. I know it is giving enouph power because i am using the card now with this PSU but i am sure there is somthing not right.
If it is only giving 36amp will this affect the performance of the card to a point were it woulod be noticable if i baught a PSU with the propper 46mp.

Any answers would be very much appreciated thanks.

Actually, it looks like you'll squeek by, barely, if the PSU isn't a total POS. Why didn't you ask the question BEFORE buying PSU? I don't recommend anything other than Power & Cooling, Corsair, seasonic, and enermax.

I did ask thats the thing, the guy who advised this said yeh yeh its fine and went on to say i use this and i have recommended to alot of other buyer's......... Ups because i am sure he is wrong i kinda hoped he would have been wright.
But will it affect performace ?

I'm not going to lie, that power supply isn't that great. It looks like a piece of OEM garbage. You should pickup a Corsair TX650 in the near future.

I think that the PowerCool PSU will power the GTX 295, but it won't be too good for it. Don't expect the PSU to last long.

I am going to take your advice but get the crossair 750 worth the extra £40.

If the card isn't getting enough amperage, it will either have decreased performance, or just not work right. I'm thinking its as if you undervolted a CPU; you're safe to a certain point, and then it wont work (correct me if this analogy is complete crap )

Yeh well going a little of subject here but the main thing which made me wonder about power is a realy crappy 3dmark06 score or 19k i have intel i7 940 gtx295 6gb ram and gigabyte x58extreme board which seems a little low.
