Pros: Much quieter than the stock Dell psu. I barely hear it. Pretty easy to install in my Dell Dimension 4700. Gives me enough power to upgrade my video card. Finally!! Feels well built. Cabling is good quality. Lots of connectors 35 amps on the 12v rail a plus. More than enough Got it for 20% off original price

Cons: For me just a few more cables than I needed. Took a little extra time to route them in a proper manner. No biggie. Still giving it 5 out of 5

Overall Review: Dell Dimension 4700. Fits good. All screw holes lined up. No gaps at all. Had to take the rear fan out of the way to put this psu in. That was easy. My first psu install. Took me around 25 minutes. But most of that was just cleaning dust out of the PC . Actual psu install probably 10 minutes. Powered on and no problems so far. This psu and the new video card will keep my dell 4700 going for another 2 years. If you have a 4700 and want to upgrade your card get this psu. You wont regret it.

Pros: Powers my E520 Inspiron, Great for upgrading your video card to the latest. I run my computer for hours gaming and it's really quiet.

Cons: When I first powered on it made a clicking sound, found out that the fan was hitting something...So i opened it up and fixed it, now it runs like a charm.

Overall Review: Problem is most likely due to poor handling, soon to upgrade to a 4890.

Pros: Works great right out of the box. Quiet. 5 yr. wrnty.

Cons: Case had to be cut for it to fit. No biggie.

Overall Review: This unit is a good buy with rebate. Be prepaired to dremel cut a small amount of metal from the case so the power plug has room to let the PSU seat properly. Protect the inside of case from metal fragments when and if you have to do this. Buy the way, the images of this unit don't show well enough the end connctors so I was worried about the 90 degree SATA plugs that my Dell needed. Well don't worry because they are included.

Pros: An exact fit for the Dell Dimension 4600, although it looks like it's upside down due to the mounting holes. Extremely quiet. More than enough connectors for the 4600 and plenty for other models that use sata and PCI-e.

Cons: None that I know of.

Overall Review: I purchased this supply to provide enough power for a video card upgrade. Just trying to get another year or so out of this old Dell. I've never changed a power supply in a computer so I was hesitant to try this. From the time I started removing the old supply until the new one was in and running was less than 45 minutes. If I can install one of these, just about anyone can. Got a great deal from Newegg, as usual, and they shipped really fast. Now I have to get up the nerve to install the new video card.

Pros: It fits a Dell

Cons: The first power supply lasted a month. I returned it to new egg they sent me another and it also lasted about a month and stopped working. This power supply is not worth the money I spent on it. It is not quiet, way too many cables.

Overall Review: Will never buy another from this company

Pros: Extremely quiet. Snaps in to the clip the stock Dell E520 PSU H305N-00 uses, takes all of 1 minute to install. Lots of extra cables - way more than required for the stock Dell Dimension E520, but they all tucked neatly into an empty drive bay and are there for future use if needed. Couldn't be easier. Very pleased with this.

Cons: None.

Pros: Excellent quality manufacturing throughout. Easy install. Mounted like an OEM supply in my old Dell 4600 case. Quiet. Fairly good documentation.

Cons: A lot of cable to deal with. Had to creatively tie-wrap and stuff away all the excess cable, PCI-E cables, etc. Will impact airflow in case, but I'm not running a hot-rod machine, and only 2nd & 3rd generation games, so it will probably be OK.

Overall Review: Very pleased with this product.

Pros: This PSU is the exact same size as the original. Plenty of power and cables. Quiet under normal operation.

Cons: Although it might be due to the limited air intake on my case, the PSU fan speed seems to ramp up under gaming load quicker than needed.

Overall Review: The trick I used to deal with all the extra unused cables coming out of the PSU was NOT to tie them out of the way! Instead I tied the unused cables to the cables I am using. That way the unused cables are spread throughout the case, they don't restrict air-flow, and everything fits nicely. It would be helpful if PC Power & Cooling's documentation mentioned that the 24-pin Motherboard connector can be snapped apart so part of it swings away via a plastic hinge to convert it to a 20 pin Mobo connector. It wasn't immediately obvious to me. System: Dell Dimension 4550, 533 FSB, 2Gb RAM, Sapphire HD 3850 512Mb AGP, Creative X-Fi XtremeGamer.
