5 out of 5 eggs

Pros: Great PSU. Comes in the box in a carrying bag, wow power and cooling, just wow. Very solidly built and comes with a 7 year warranty.

Cons: The excess of cables made management a little difficult, but that's all part of the fun of building a PC.

5 out of 5 eggs

Pros: Doesn't ever get very hot, and it pretty quiet most the time. Comes with plenty of cables, and can be organized to keep cables out of the way.

Cons: Although the cables can be organized, it does to take some doing to get there. I recently upgraded to an EVGA GTX 550Ti, which is slightly big, but after some reorganizing, the cables are out of the way.

I suppose this isn't even really a con, but it's something to consider

Other Thoughts: Can get noisy at higher fan speeds after prolonged use. After about 4-5 hours of WoW, it doesn't really get TOO loud, but the sound does go up eventually.

5 out of 5 eggsCool and Quiet!

Pros: All possible connectors available. Plenty of cable length. Quiet and plenty of power! Good price for 500W (I got it on special)

Cons: None so far!

Other Thoughts: Had to replace a dead 350W PS. Didn't really need 500W, but with the deal on price and the 80 PLUS BRONZE Certified this was a good buy.

5 out of 5 eggsGreat value in a 500W PSU

Pros: Great warranty, quiet, single +12V rail, power ratings are at 45°C, 600W actual peak output, spiffy packaging, value w/rebate

Cons: None as of yet

Other Thoughts: I’ve only purchased a couple of PSU’s in my time building PC’s and this is my first from PC Power & Cooling (now apparently under OCZ). I was drawn to the unit mainly due to pricing/value and warranty, and the fact that a larger unit was overkill for my older core 2 quad system. The 500W Mk II Silencer seems very impressive for the money: I got it for under $50 with the rebate, which I received in about 4 weeks and was fairly painless. The unit has all the cabling you should need and a great warranty for the price. The warranty is actually 5 years however, not 7 as noted by Newegg above the pricing information as of this writing; still 2 years better than most all other PSU’s in this price range. No issues with install/function aside from finding a place to stash all the unused cables which is relatively easy in a mid-tower case.

5 out of 5 eggsAmazing First Purchase!

Pros: I was very worried when I finally decided to purchase this one over others. I always read the reviews just to make sure. Price is never an issue with me. However, I was on a budget and this was perfect.

The material that it is made out of is just top grade. I honestly liked the mesh coverings over the wires. It really makes the inside look and feel better.

Setting it up wasn't as easy as I hoped, but (not being technical) it was a lot easier than expect. What I mean by this is that it was as easy as plug...plug...plug...screw...screw...screw...done! However, it doesn't come with twist ties or anything to tie up the excess wires.

I am also relieved to find out that this wasn't a DOA (Damage On Arrival), because I heard that many boxes come as DOA. I would assume the problem is the handling (FedEx or UPS) but people seem to blame the manufacture instead. Puzzles me.

Cons: This ad says 7 year warranty, but it is really just 5. I'm cool with 5 (which is plenty), but I just wanted to let others know.

Too many extra wires.

Other Thoughts: Overall:
Simple install
No issues
High Quality
5 Year Warranty

I would recommend it to a friend.

5 out of 5 eggsVery happy with this supply

Pros: Reasonably priced, very quiet, single rail, high current output on the 12V rail, tons of connectors. The cables are long, but that can also be a con since it makes them harder to stow. Quality seems to be back up on top. It got lackluster for a time after the ownership change.

Cons: Not modular, but that can also be a pro since the additional connectors modular supplies utilize can reduce connection integrity. For a mid-range system (which is usually what you buy a 500W supply for), it can be hard to find room to stow that many unused connectors and cables.

Other Thoughts: I've been using PC Power and Cooling supplies exclusively as long as I can remember. I replaced an old Silencer 470W with this unit. That old power supply had a lot of hard mileage and was getting noisy. It didn't have a real high output on the 12V rail either, only 26A. There are a lot of surplus cables and connectors on this new supply. I'll never have any forseeable need for 8 SATA and 8 four-pin Molex. I only need half that. Fortunately, my case is pretty big and I found room to stow them. Going from a supply with a 80mm fan to one with a 135mm fan made a huge difference. My PC is so quiet now, I can only hear the hard drives spinning. It seems strange, so used to that fan noise I always had before, so glad to be fully rid of those noisy 80mm fans now.

5 out of 5 eggsGreat PS

Pros: Higher than advertised wattage is always a plus. Very solidly built power supply with meshed cables. Quiet fan. Five year warranty is nice.

Cons: There are many cables that will be unused and will have to find a large area to store them in your case.

5 out of 5 eggsSpend less get more with PCPower&C.

Pros: -Smells really good out of the box.
-Nice and neatly packed with one of those draw-string bags.
-Materials look and feel high quality.
-Right amount of cables, not too much and not too little.
-Longer warranty than others.

Cons: None.

Other Thoughts: Bought this for the core 2 duo machine that I'm passing on to my parents and it is well worth it.

I was expecting an overload of cables but it was just the right amount compared to my corsair gs-800 which feels like it has double the amount.

Regretted not getting the PCPower&C 950W instead of the corsair for my own machine but will keep in mind for future upgrades.

Rule of thumb - Only get power supplies from newegg for the best deals.

5 out of 5 eggsNICE!

Pros: My gosh is this a quality PSU. It's quiet, it feeds a very power-hungry machine, and by installing this PSU and replacing the cheap 430W that was in the PC before, I was able to get some real performance out of my buddy's rig by:

- unlocking the 4th core on his Athlon II X3 (with the 430W thermaltake we had in there, the power draw became too much and caused crashes -- been running flawlessly on this!)

- powering and overclocking a GTX 280. This card has a TDP of 236W and is used 6-7 hours a day at full usage -- and this PSU lets me OVERCLOCK this sucker without a problem.

- It looks amazing. You can tell that PC Power&C actually took pride in their presentation and seemingly in the quality of the components.

Worth every cent of its asking price. DON'T EVER GO CHEAP ON A PSU!

Cons: None.

Other Thoughts: Don't be fooled by power rating on cheap PSUs. If you buy a $50 700W PSU, it is most likely nowhere near as good as this unit is. Make sure PSUs are rated for *continuous* output, and make sure that the wattage is actually legit -- a lot of PSU manfuacturers put most of their wattage out on the 3.3V and 5V rails, which don't need all that much power. The 12V rails' amperage is what matters, and quality PSUs like this deliver.
