Which power supply should I buy ? + list [700 watt+)

Hey,

I currently have a CoolerMaster M700 Silent , which has a 135mm fan. But the fan or the fans motor started to make a weird noise. I requested RMA and I can choose from the following power supplies:

Antec New TruePower SLi 750W (ATX, SLi)
Be Quiet Dark Power 750W PRO (ATX, v2,2 , Modulair, BQT P7-PRO 750W)
Zalman 750 watt (ZM750-HP)
Zalman ZM850-HP, 850W
Antec TruePower Quattro

Which power supply is the most silent?
I'd say the Zalman ZM850-HP is the quiest but I don't know for sure

My setup:

Core i7 920 (with overclocking)
Gigabyte UD5
3GB OCZ DDR3
XFX GTX 280 1GB (with overclocking)
1 x Samsung Spinpoint F1 1TB

Hello & welcome to SPCR!

I can't imagine that your system needs more than HALF that power? I think a 500watt PSU would be more than enough power, and would probably be much quieter, too.

I'm planning to go for quad sli in the future

I'd probably pick one of the zalmans assuming they're similar to the ZM1000, which is amazing at staying at low fan speed far longer than most other psus.

You want to run Crysis in 2560x1600 with very high detail or what?

We expected Quad SLI to blow us away in games and prove why we needed to spend $1000 on it. What we were left with though was a feeling that it didnâ€™t provide us with anything, nothing that would make us want to install it in our own system as a gaming platform right now. Even at 2560x1600 it seems most games are content with a single GTX 295 or equivalent.

The only game where we saw a distinct advantage at 2560x1600 was Crysis: Warhead.

Ever heard of benching?

Also in the review they use ''old'' hardware.
Which means the CPU limits the GPU's power

The Zalman doesn't have a on/off switch on the back. ouch... also it's 21cm long maby it doesn't fit in my case

thing is you can get a decent power supply with plenty of power now.

put at least 100$ for a good-quality and quiet power supply such as the Enermax Modu82+, Seasonic or Corsair (also made by Seasonic), if you're going to buy a TX-series Corsair, buy the 650W one, since the 750W have a 140mm non-standard fan, harder to replace it if you're going to change the fan inside, and i think the maker is different also, and maybe a little longer.

I can't believe they make huge power supplies because they have more power, it seem like they could make a 1000W PSU with the same size as that Corsair TX650W.
