OCZ recently bought PC Power & Cooling which was well known for high quality power supplies. This unit is a PCP&C workhorse delivering 750 watts of clean steady power. There is one 12 volt rail that carries 60 amps. The fan is very quiet (but not silent) and the power cables are long enough to cover a full tower computer case. One thing to watch for is that the unit is slightly larger than most ATX power supplies and might pose a problem for small cases. This unit would be great for overclocking and dual video card configurations but is probably overkill for most home systems.

Having written PC hardware reviews for over 4 years now, I can honestly say that PC P&C is the Creme de la creme when it comes to Power Supplies that are built with two goals in mind... Performance and Reliability. These PSUs offer that in spades.

A little interesting fact that you should be aware of is that a PC P&C PSUs wattage rating is its lowest, max sustained power rating... In other other words... on a 750W PC P&C, 750W is the minimum power you will have access to under less than optimal conditions. EVERY OTHER PSU MANUFACTURER handles their wattage rating a much different way: Their 750W rating is the PEAK power output under optimal conditions (with the regular power actually delivered under less than optimal conditions being significantly lower. ie. a 750W rated PSU is its max rating and will most likely provide around 650W - 675W normally. Bottom line... PC P&C Wattage rating is a MINIMUM rating and all other PSU Wattage ratings are a MAXIMUM rating. 'nuff said!

During my trips out to E3 and CES to provide coverage at those events, I had many opportunities to speak with marketing reps and engineers from other competing PSU manufacturers and each one, when the topic of PC P&C products were brought up, they all said that PC P&C offers THE superior product in their field which all other companies strive to live up to. PC P&C PSUs are the industry standard for top of the line, PSUs.

Like was mentioned before, the only thing missing from their PSUs that some people cannot live without (if they are not experienced in dealing with hiding wires in a PC for good airflow and presentation) are the modular cables that nearly all other PSU manufacturers offer. PC P&C ignores this borderline-gimmicky feature since introducing modular connectors to the cables increases electrical current resistance, which degrades the overall performance and efficiency of the PSU. Remember... PC P&C focuses on delivery performance and reliability above all else; and that is why, for the past 5+ years, all of the PCs I have built for myself, friends, sponsors, etc. have all had a PC P&C PSU powering it.

The current price of ~$85 for this Silencer 750W PSU is a STEAL! I have had a modified Silencer 750PSU running my main design/gaming machine 24/7 for the past 3 years or so and it has been rock solid! Intel Q6600 running at 2.85GHz, EVGA 680i SLi Motherboard, 4GB PC1000 RAM, EVGA 8800 GTX, x7 hard drives, optical drive, x2 12v water pumps, x6 120mm cooling fans, SoundBlaster X-Fi Extreme Gamer, and more.

PC P&C should ALWAYS be your first choice among PSUs when given the option to choose.

This is an excellent PSU. With all the connectors i need and more.
Doesn't make noise. Just a little spinning sound but nothing to worry about.

Great power for a strong machine. (750 W)
I use it for a Core 2 QUAD with 4 GB of memory and 500 GB HD and 256 MB VIdeo Card.

100% Recommended.

I purchased this power supply 4 months ago and ever since then its been running my pc 24/7 with stable voltage.Also great shipping and fast!!

I originally had a ~300W PSU (which came with my Dell PC) and it did the job for all of the stock hardware, but when I upgraded my video card I started to have problems with my PC. It would randomly freeze and turn off, probably due to the PSU not being able to handle the wattage. Once I saw this on Amazon, I decided to try it out and it's well worth the money. The only NEGATIVE thing I'd have to say about this is that it's a mess! There's many cables, they're pretty thick, and if you have a smaller tower (like me), it's a bit frustrating to install... but overall, after you've pulled your hair out trying to connect everything, it's well worth it. It's pretty quiet, not silent, but it's nothing to worry about.

I'd definitely recommend this to any buyer.

This is a great Power Supply, was PC Power and Cooling Company. Now OCZ bought them out. One of the BEST power Supply Company's around.
Amazon had this at the lowest price I could find on the net.

Very high-end components are used in this fantastic power supply. It is so quiet that you may attempt to hit the PC start button twice thinking the compter did not start. The wiring is as good as it gets in power supplies. Worth every cent it costs. .

I build many computers and have not found a better power supply for gaming machines. It is rock solid after two years of heavy use.

I have done a lot of research on power supplies and out of all of them PC power and cooling is my favorite. I first bought a dell silencer 500 for my dell inspiron 530 and it worked great. I never had a problem and always had clean stable power. I am building my first pc mostly for gaming and the silencer 750 is awsome. Its bigger in size than the 500 but again clean stable power. Powerful 12v rail and lots of sata and molex connecters. it also has a 4 pin and 8pin cpu power connecters for the motherboard and 6pin and 8pin PCIE connecters for the graphics cards. I am very pleased. There is a review video on this PSU on [...] Hope this helps!

I've been using this for about two months now in a new computer build.

Pros:
- It is very quiet. Not "silent," but it is quieter than the 600W power supply I used to have (a Xion).

- No, it isn't modular. Yes, I'm putting this under 'Pros'. PC P&C's literature explains why they do not make any modular power supplies. The upshot is that adding modular connections increases electrical resistance, reducing the effective output of a PSU below its rating.

- 80 PLUS Certified, meaning that it is greater than 80% efficient = lower power bills

- This has plenty of connections. 24-pin, 8-pin and 4-pin MoBo connectors; four video card connectors (two 6-pin and two 6+2-pin); 6 SATA connectors; 8 peripheral connectors; a floppy connector.... I think that's it

- The single 12V rail is also nice. There's no need to try to 'balance' the load on multiple rails

Cons:
- The only one I can think of is that this PSU is a little 'deeper' than most. That's to give it a little buffer between the fan and the internal components, which is what makes this a quiet PSU. But with the large bundle of cable coming out of it (again, it has _plenty_ of connectors) it can be a bit tight in a mid tower. I have 5 5.25" bays on my tower (a Cooler Master Centurion 534) and only have optical drives in the top two bays. Those empty bays gave me plenty of room to store the extra cables.

Conclusion:
- This is a great power supply for a beginner or for an advanced builder.
