5 out of 5 eggsGreat

Pros: Really, REALLY SHINY!
Works great, no problems. Good brand.
Feels expensive and solid!

Cons: The cables are too darn thick, in my opinion. If you have a light build, you'll be fine, but don't expect to be hooking up 6 hard drives and two GTX 480's. They were so hard to bend that I wound up chipping one of the sata power plugs. Give em' a good twistin' before you use em'.

Other Thoughts: Other than the cables, great, recommended buy.

5 out of 5 eggsmushkin hasn't let me down yet

Pros: Modular cables, awesome capacity at low wattage (4x12v rails @ 20A!!!) w/ railfusion for a max of ~44A. This supply can deliver better stats than some 800w supplies. Wasn't clear for me from the pic, but it's sort of a polished gunmetal look, very slick!

Cons: newegg shipping took unusally long to get this to me. Never been a fan of the green LED that Mushkin so loves in their PSU's.

Other Thoughts: This is my 3rd mushkin PSU. No failures or DOA's experienced. Buyers -- you may be tempted to shop by wattage but the only reason graphics cards and other hardware shows wattage is it's a general rule of thumb that more wattage = more amps, and AMPs is what you really want. Shop smart, and read the white label on the side of the supply before you buy. Mushkin delivers the stats for a decent price.

4 out of 5 eggsargh...GREEN!

Pros: beautiful power supply. plenty of power, sli ready, quiet, modular.

Cons: i was looking for decent power supplies for a budget sli build using some video cards from some friends. i saw this guy, said to myself, "mushkin? sli ready? modular? yeah!!" but when i plugged it in and turned it on, a glaring green light hit me from the rear fan. there is no mention of the existence of an LED in the specs! i wanted this because there was no light! what's worse is that the rest of my case lights are blue...

Other Thoughts: all in all this is a great power supply, i just really, really wish there had been mention of the LED

5 out of 5 eggsReplacement

Pros: This is a very nice modular powersupply I have no complaints with Mushkin powersupply equipment at all. I was a little concerned with the size of the fans over my original 580 watt Mushkin (which has been discontinued now). But the unit stays nice and cool so far even under load.

Cons: None at all, rock solid PSU.

Other Thoughts: I received this as a replacement for my burnt out 580 watt Mushkin (purchased from Newegg 2 years ago). I don't believe the old powersupply was faulty I think it was a series of cascade problems that resulted in the 580's death. With that said, I phoned Mushkin and they whisked me through the RMA process and I had this replacement in my hands in 2 days. I have nothing but good things to say about their RMA and replacement policy. Great company, I highly recommend them if for no other reason then they stand behind their product 100% and the staff are friendly.

5 out of 5 eggsVery good P/S

Pros: Very solidly build P/S. One of, if not *the* best packaged P/S I've ever bought; and I've owned Antec, Enermax, CoolerMaster, PC Power & Cooling, Sparkle, Enlight, and generic garbage that comes with some cases. Dusky-chrome finish is superb! Dual fan placement of front to rear keeps the air flow going the correct direction. The ATX spec is designed to vent hot case air through the power supply and out the back. Very quiet in operation. BIOS reports power is less than 1% off target voltages with motherboard temp at 85 degrees F. Sports a separate grounding line which I attached directly to the case rather than a motherboard retention screw as per the directions. After all, common ground is common ground.

Cons: The main 20+4 pin power cable, and the two P4 power cables are a little short in my experience. For me, the P4 cable *barely* reaches. Forget about hiding the cables, they simply are not long enough. Didn't deduct an egg for this since your mileage may vary given the huge variances in case and motherboard layouts. On the other hand, the SATA and Molex power plugs are WAY long. 4 SATA plugs on a single cable seems excessive.

Other Thoughts: The fan is lit with green LEDs. I'm rather bummed that a $40 rebate became available 3 days after I purchased mine. :( Normally I'd avoid a modular P/S but this was for a HTPC and I wanted to avoid added clutter in the already tight for space HTPC case. Note that the two BLUE modular sockets are for PCIe use only.

Pros: None

Cons: Everything! This Power Supply didn't work AT ALL, out of the box. I have been an electronics professional all of my life. I have "tinkered" with this faulty Power Supply every day, in order to try to get it work. Nothing has worked so far; and, I doubt that anything ever will. Now that I've been working on it for over 30 days, won't even talk to me about it, simply because it's been over 30 days. To anybody that happens to read this, DO NOT BUY THIS POWER SUPPLY! You will be sorry! Also, you may be sure that I will never again buy anything from THE END!!! Oh, by the way, they wouldn't even let me submit this evaluation unless I clicked on at least one of the five eggs in the overall rating field. So I did. But you may be sure, that if any product deserves a 0 (zero) egg rating, this one does; and, so does for their completely deficient customer and product support.

Manufacturer Response:


Thanks for Choosing Mushkin Enhanced. For assistance with an RMA for this unit please contact We apologize for the inconvenience this has caused you.

5 out of 5 eggsExcellent psu

Pros: Modular design is flawless, I'm able to pick the cables I need and just plug them in. Power is always constant and I never had any power issues in over a year. Love the glossy finish

Cons: The cables are somewhat hard to bend, but it's not that bad of an issue.

Other Thoughts: Running an evga 8800gt oc, intel e6750 oc, 2gb ram, abit ip30 pro mobo, sony cd/dvd drive, seagate sata-II hard drive, creative labs xtremegamer sound card, 5 case fans

4 out of 5 eggsWell built, perhaps too well.

Pros: High build quality (it also weighs a ton), sexy cabling job. Seems to power my computer well. Got a good deal.

Cons: Would have been nice if it had a 6+2 PCIe connector. Also, the beautiful cables are very stiff which makes routing them somewhat difficult, especially in a case with side mounted hard drives.

Other Thoughts: Satisfied, but if I'd know how big a pain it would be to route the SATA power connectors around the side of my CoolerMaster Scout case, I would have probably considered a different power supply.
