SilverStone OP650 650W ATX 12V 2.2 & EPS12V SLI Ready CrossFire Ready Active PFC Power Supply

Pros: I'm an an@l person and did a LOT of research before I put my last build together (plus 6+ other builds for friends and family). This PSU puts out stable voltage and powers my mid to high-level gaming rig perfectly. Easy to install (but all PSU's are), and so far reliable after 6.5 months. I am very satisfied.

Cons: More than a tad more expensive than some other PSU's I considered (like Tharmalt@ke), but the stablity and high marks around the web (not just newegg, but other PSU-centric sites) made this a good decision.

Overall Review: FYI... This powers 3 SATA-300 HDD's(320gb, 250 gb, and 160 gb), an EVGA 8800 GTX, AMD X2 6000+, ASUS M2N-E Mobo, 3 Gigs of Crucial DDR2 800, 2 SATA DVD burners, several 120 mm LED fans, and I feel like I could add anything else and it wouldn't miss a beat... aka I am very happy with my purchase. I used this for 3 other high-end C2Duo customer builds and I haven't received a single power-related tech call yet after 6.5 months (Can't say the same for the last round of @ntec 550W's I bought...2 of 3 crapped out within a year) Awesome!

Pros: Voltages are dead-on or just above rated running a Pentium-D @ 3.9ghz, an x1950pro, and 4 hard drives. One 54a 12V rail so no load-balancing issues. Runs cool and quiet. Active PFC. Completely stable so far.

Cons: All of the cables could have been sleeved, but I can hide them so it's not a huge deal. It's a bit too large to use with the PSU support bar in my Armor case, but it shouldn't be an issue as I don't move it around much (it's extremely heavy).

Overall Review: I haven't had the fan issue that some mentioned (guess Silverstone fixed it), and it's run very quiet thus far. I purchased this power supply as I wanted one with a single 12V rail that wasn't modular. So far I have not been disappointed, and will definitely look at this company in the future.

Pros: Really impressive. Long plentiful wrapped wiring. Comes with a power cord the thickness of a sharpie not a pencil sized cord supporting the PS. Packaged well.

Cons: None found.

Overall Review: I do not like 98% of the PS's I use. I keep trying to find the one. Well the hunts over. I would not use this in a typical desktop it would be overkill. But when I have mission critical hardware this one will be used. I do not doubt it will be reliable.

Pros: I owe Silverstone an apology. It turns out a capacitor fried on the motherboard. Because the PS has a fan it sucked up the burnt electronic smell and it stayed in the PS so I thought that was the cause. Turns out I was wrong. I am still using this PS and has worked great. Quiet and powerful. Sorry Silverstone and thank you for a solid product.

Cons: none

Pros: EXTREMELY stable power output. Powers my over-clocked machine without any problems whatsoever, while being totally silent at the same time. Excellent reviews online, even if they were a bit old. Worth every cent I paid for it.

Cons: It made my case heavier?

Overall Review: I make a point of not reviewing power supplies for at least a year after I've installed them. To see how well they hold up.

Pros: Runs great! Lots of power!

Cons: after 20-30 boot-ups of the computer, i was just sitting in windows vista, and the computer froze. So i turned it off and back on, then got a bios beep code that matched a power error code in the Gigabite motherboard manual. After trying to get it to come back online, i made it to the boot up screen to get into the bios and it died again giving me the same bios beep error for a power failure.

Pros: This provides a relatively large amount of power for a pretty good price and is VERY QUIET. Compared to my last power supply this thing is almost silent. The first time I got it properly running I thought I blew it (again) because it was so quiet. Even a month after purchasing this, I still get a kick when I turn it on and my cpu fan makes more noise than the powersupply, and my cpu fan is quiet too.

Cons: not all the wires are wrapped in the black mesh, but this is nothing big.

Overall Review: I went through around 6 of these powersupplies before I was able to figure out what was going on. Turns out one of my xeons got fried on my old powersupply and eventually fried my NCCH-DL motherboard, but once I got all the parts replaced with new stuff, there was no problem at all with this powersupply

Pros: Absolutely awesome PSU. I mean, just by looking at the box, you can tell it's quality (seriously.. how many other PSU boxes have a CARRYING HANDLE?!). But seriously, if you want a power supply that can handle the newest hardware while still maintaining a low profile, this is it.

Cons: None

Overall Review: Rebate makes it sweeter.
