OverviewCustomer ReviewSpecificationsProduct Tour
Okay, it's a power supply. Not much excitement there unless it starts smoking, right? But if you can't work up excitement, how about some respect? Like the 41 Ampere +12V rail (and there's just the one +12V rail, so you don't have to balance your power needs by hand.). How about the ability to auto-sense your input voltage from 90Vac to 264Vac, 50/60Hz? No more damaging your supply because the voltage selector was in the wrong setting.

Run cooler, too, because it can be up to 85% efficient, meaning less waste heat from the supply. Compatible with both ATX 2.0 and ATX 2.2 systems, it includes long cables for even full-sized tower installations. Nvidia SLI support It includes power connections for six SATA drives. A 120mm variable speed fan with double bearings gives good airflow with minimal noise. Active power factor correction helps deal with inductive loads (drive and fan motors, mostly).

A modern power supply for modern computers, just for you.

Worth Every Cent

white Reviewed By: Baseem on 11/19/2007
Rating + 5
Tech Level Tech Level: high - Ownership: 1 month to 1 year
This user purchased this item from Newegg
Pros: Every connector you could ever need. VERY quiet fan. I'm running 2 HDD's, a dual core processor, PCI video card, a few case fans, and 2 DVD-R drives without any issue (as would be expected). One of my buddies referred me to Johnny Guru who gives a top-notch appraisal of this unit:
Cons: I didn't suck it up and buy a good power supply years ago.
Other Thoughts: I must have bought no less than 7 or 8 cheap power supplies in the last decade. Every time one went out, I rushed down to <insert generic computer parts store compatible with newegg's review policy> to buy the budget $30 everyday low price, everyday low quality power supply. This time when the original power supply that came with the case died on me, I thought I'd see what the expensive power supplies were all about. My conclusion: "they're worth it."

This user purchased this item from Newegg
Pros: Excellent build quality. Components, case, cables, and even the resail packaging are all top notch.
Cons: I wish there was a connection to monitor fan speed, but this is minor. Also would like modular cables, but also not a big deal.
Other Thoughts: No problems running with an Intel Q6600, 8800 GT graphics, 2 hard drives in a striped RAID, and a CD/DVD drive.

Very Nice

Tech Level Tech Level: somewhat high - Ownership: 1 day to 1 week
This user purchased this item from Newegg
Pros: Quiet; quality build; plenty of power. The demands of my system are a modest 320 Watts (no video cards). I thought it better to have a 550W psu operating at 60% capacity than a 400W psu operating at 80%. More expensive than others but quality and a 5 year warranty make it worth it to me.
Cons: None
Other Thoughts: Use the power supply calculator that Newegg has to help you calculate your system's demands. As per usual "Newegg Rocks" - I ordered Monday PM and it arrived Wednesday PM.

Tech Level Tech Level: average - Ownership: more than 1 year
This user purchased this item from Newegg
Pros: Easy to install, had no problems and got it setup in about 20 minutes. Cable's are nicely wrapped together and it comes with zip ties. Cables are very long. Love the black finish on the power supply itself. Comes with a Corsair badge/sticker.
Cons: Almost too many cables, but you can't really argue that. The more the merrier.
Other Thoughts: Great PS for the money.
