PSU need a new psu

i need a new psu and was looking at these ones,

450W Corsair CMPSU-450HXUK, not sure about using a single rail?

480W Be Quiet Straight Power CM E7

525W Enermax MODU82+

any one have experience with these?
any help would be great!

 

What's your current hardware spec, and what do you anticipate your hardware being in the near future?

What was your old PSU?

 

i have been using x-power psu's for a few years, overclocking, gaming, etc , no probs
i want a modular psu for reduced cabling, better cosmetics, but custom pc have got me paranoid
id be gutted if it did fail taking my hardware with it, ive measured maximum load on a wattage meter at around 270 watts give or take a bit, so i dont need really high wattage and cost is also an issue, i probably wont be using crossfire any time soon,
so if was just looking for anyone who may have used any of these, im leang toward the be quiet
straight power.
thanks!

 

I have a corsair hx850w and i have had no troubles with it so far it runs super quiet

 

i have corsair tx 650 ive compared reviews and stuff their solid reliable psu's

 

The Corsair HX450 looks to be good value. A single 12V rail is not a problem. The only reason rails are split is compliance with the ATX12V standard.

 

I was gonna say, I've got a TX850W and it's very nice but a little bit GROSSLY OVERPOWERED for your needs (and mine). That said, they make great PSUs and the HX450W is a great bit of kit for a very nice price, I'd recommend it. Alternatively, and for more power, Bit recommends the OCZ ModStream Pro 550W, though again it's quite powerful and I'm not sure about the cabling situation (semi-modular, I think).

Either is a good bet.

 

thanks for all the reply's ! i have read good thing's about corsair psu's, i just wasnt sure about pulling all the power from a single rail.
thanks again!

 

Actually It's now just to adhere to tradition and to reduce the severity of a PSU dying, a while back intel quietly edited the standard so it was only a recommendation rather then requirement for ATX12V standard.

And from personal experience with corsair, I have 1 with another on order, my friend has one and I know a few other people who have them, and one thing that we have in common is stable computers, you can't go wrong with corsair when it comes to stability.
