I've been using ST56F since last year October till 2008 July till it boomed. RMA-ed it and got back a new 1, working fine and feels powerful

If you've got money, get Silverstone pure power series, they feature single rail >.<

Power efficiency low? Low ampere rating or low voltage rating?

Is it a pure power series PSU?

I don't think so, with so many fans, rams, hdd & expansion card, better get something above 500W with 80plus.

What kind of buzzing sound?

Is the Huntkey x7 single rail? Most people would go for single/dual rail for high-powered PSU.

During minimal load or moderate we wouldn't use up to 500W. And 5 rails? Hmm..

Have you seen Huntkey X7 900W's review? It's certified 80+ Silver, which is quite impressive. But look at the 12V rails, only 18A each..

VX550W single rail? But then again, 550W seems a bit low for GTX260 SLI. If you're using quadcore, CPU alone already take up more or less 100W depending whether or not you overclock it. I tried HD3870 CF with ST56F and it was no good, insufficient power and made my benchmarks' scores go even lower than it already was.

I also noticed CF/SLI can run without crashing eventhough power supplied to them is not sufficient, but the drop in performance gain is noticeable.

The fan's loud? Have you checked their temperatures?

Why not get CM Silent Pro M850? Its 850W single rail its modular and cheaper compared to many others. The OEM is Fotron for the M850.

Once, I used Xigmatek's NRP-MC751 for 9800GTX+ SLI with C2D overclocked to 3.4ghz, the voltage on 12V1 rail wasn't satisfying, it dropped after SLI. As far as I know, 9800GTX+ single card system consumes about 240W peak load with an overclocked C2D; whereas GTX260 single card system is about 300W peak load with an overclocked C2D.

Usually they'd recommend 700~800W 80+/true-power PSU for SLI users.

RM545 by Lalaman http://forum.lowyat.net/index.php?showtopic=546378&hl=

or Silent Pro M1000 RM685 by Lalaman also.

850W? I doubt. Go for 1000W

Cooler Master Silent Pro M600 XD

Robyncom @ Imbi Plaza. I bought it at RM335 only

What's your specs?

How can solid cable pawn modular cable? You mean the very slight resistance encountered when connecting modular cables? The resistance is negligible. But between GX series and Silent Pro series I will go for Silent Pro M700 if you're aiming at GX 650W. The GX series has higher amps compared to Silent Pro but without modular cables.
