PSU advice please

[FishPolice]

Been running the spec in my sig for about 4 years now at a nice stable overclock of 3.4ghz.
I jumped on the hd 6950 band wagon a couple of days ago and am looking to shoehorn it into my system later this week.

I think I really ought to consider a new psu for this new card -especially since i will probably upgrade to Sandybridge later in the year. Taking a chance otherwise yeah?

What I want is a very quiet, modular, reliable psu with plenty of oomph for gaming to last me another 3 to 4 years. What i don't want to do though is pay silly money for power i will not ever need.

Will need to also run 3 or 4 ide + sata hdd drives, perhaps an ssd drive also, dvd drive, sound card as well. System will be overclocked and will be mainly for games.

**Psu needs to fit into my Antec p150 case (is this a midi case?). Psu needs to be practically silent.**

Budget about £50 -60 inc vat <-- is this realistic?

Any suggestions please?

Nothing you get for £50-60 will be a significant improvement over a Corsair HX 620, in terms of power or quietness, perhaps in efficiency terms tho, aslong as the unit you pick up is Bronze level efficient. I suppose if you could find a deal on either the Antec Truepower New TPN-650 or XFX 650W XXX Edition then those might be worth it, but their fans run all the time. The SPCR review showed the 750W version was very quiet up until about 400W load, and imo you are unlikely to be pushing your system anywhere near that hard, so maybe it would be good enough for you.
I think you will be looking at £100 or more for something really high quality and high powered with either a really quiet fan or semi-fanless.

You shouldn't be too worried about running a Sandy Bridge system of a 500-600W unit, because the SB CPUs are very power efficient, the maximum TDP for the range is 95W, and they actually use even less than Lynnfield processors.

You do not need a new psu. Your Corsair is a quality unit and your rig will come no-where near it's 620w. The rig in my siggy only pulls a max of 384w at the wall and even then only by running Prime and Furmark stability test both at the same time. Normal gaming usage is 234-275w depending on the game.

Agreed it is a quality psu & incredibly quiet. But after this length of time will it still be ok & is it likely to last another 4 years? Also, *if* it were to go pop, would it take anything out with it?

I wouldn't worry to much.

Even if it does go pop in 3 or 4 years time there is a good chance it won't take out anything with it.

I had a hiper 580 that went bang with a nice ball of black dust and that didn't take anything out on its way. Replaced it with a much better Bequiet PSU
