Techguy1 :
Yeah I have heard really good things about that seasonic x650w, to bad the sale isn't in Canada.... Do you think that it is worth the $160 +$14 shipping? And are there any other sites that sell it? I have looked but it looks like newegg only sells it. :/
Hi - try amazon.com, they ship internationally. I don't know if it'll be worth
it or not, but no harm in checking it out. The Seasonic X-650 is an
outstanding PSU, here's a couple of snippets from jonnyguru:
"Well, I guess I'm the only one screaming in here, and it's due to excitement. In test two, the X650 is actually more efficient than it was cold, and even test five barely sees any drop. This platform is really outstanding when it comes to pure efficiency.
Know what else is outstanding? The fact that the unit was still fanless in my hot box. Sure, it only stayed off for test one, but let me be honest here - I've never had a fanless unit stay fanless in the hot box. It just gets too hot for most fanless units to stay that way.
And look - I did get the unit up to high ambient temps. Forty eight degrees, to be specific. Forty eight marshmallow roasting, butter melting, finger burning degrees, to be prolific. For-ty eig-ht de-gree-s to be sporadic. But look - the X650 didn't mind one bit. Why, it barely added any of its own heat to things, only hitting fifty nine by the time test five was over. For a while there, I thought the thermometer was faulty. Even better, the fan was barely spinning at all through the whole session."
• "Seasonic Patented DC Connector Module with Integrated VRM * [Voltage Regulator Module]
This patented full modular design minimizes voltage drop and impedance, maximizes efficiency and enhances the overall performance for cooling and reliability. *Patent Pending: US, CN, JP, TW & DE
-Impedance? I think the word you want there is "resistance," Seasonic. Impedance is a function of AC power, not DC.
o Benefits:
Minimizes resistance and voltage drop to maximize efficiency.
Consolidates and minimizes component useage to create space to improve airflow for better heat dissipation & cooling.
Extensive use of Al & SMD automation reduces human error and improves reliability.
Simple & ingenious design for a clean layout achieves unsurpassed quality and performance.
• 80 Plus® Gold Certified
At least 87%, 90%, 87% efficient at 20%, 50% and 100% operating loads, respectively.
-We'll have to see in the load testing part of the review how well this unit does in meeting these targets.
• Seasonic Patented "Hybrid Silent Fan Control" *
An industry first, advanced 3 phased (Fanless, Silent, and Cooling Mode.) thermal control balances between silence and cooling. *Patent Pending: US, CN, JP, TW & DE
-I'm not sure about this one. We've seen fanless before, and we've seen operation that ramps up the fan according to temperature before too. What's new and different here, exactly, that needs patenting?
• Sanyo Denki - San Ace PWM Silent Fan
The superb high-grade San Ace Pulse Width Modulation fan pairs perfectly with the Hybrid Silent Fan control circuit for super low noise & cooling performance.
-Interesting... I'm not sure fanless operation has been done with a PWM fan before. Maybe that's what they're patenting."
o Benefits:
Reduces noise without increase in temperature.
Extends fan life by eliminating unnecessary rotation.
Optimizes heat dissipation at all times.
Fanless mode (0 dBA) provides unsurpassed silent performance.
• Active Power Factor Correction [99% PF Typical]
Reduces line loss and power distortion.
• Highly Reliable 105°C Japanese Brand Capacitors
Exceptionally reliable components extend product life.
• Conductive Polymer Aluminum Solid Capacitors
Enhanced stability at severe operating conditions.
• Tight Voltage Regulation [±3%]
• High +12V Output
• Dual Sided PCB Layout
• 5 Years Warranty
• Full Modular Cabling
• Universal AC Input [Full Range]
• Multi-GPU Technologies Supported
• Patented Easy Swap Connector
• All-in-One DC Cabling Design
However, the Seasonic built XFX pro 650 or 750 seem to be very good deals,
and may be your best bet on a quality PSU for your system.
