SeaSonic SSR-360GP 360W ATX12V v2.31 80 PLUS GOLD Certified Active PFC Power Supply

Pros: Got this to replace the Corsair CX430 supply in my NAS (the older model that was only 80plus rated). Load power usage dropped ~25% - from ~125w to ~92w, which is only 10w higher than the idle power use with the old supply. Definite pro, since this was the only real reason for switching supplies.

Quiet, no fan noise or coil whine over the drives or other fans in the system.

Peak wattage a fair amount higher than 360w. Combined with all that load could be on the 12v rail, and this could be a handy supply for HDD based file servers.

Cons: A bit on the pricier side, but I was willing to pay it for a gold rated supply as well as Seasonics reported reputation.

Cables are a bit stiff.

Other Thoughts: Guess I should note I don't have the proper equipment to test power supplies the right way, but it hasn't fried yet.

Used in the following system:
AMD Sempron 140
4GB RAM DDR2
5x2TB Hitachi 7200RPM drives, 1x40gb WD 5400RPM drive
6 120MM fans, 1 140mm fan (all low RPM)
Intel gigabit PCI NIC

Wattage reading took from UPS during sustained file transfer plus file search.

Pros: Works fine. No problems hooking up.

Cons: It is a noisy son-of-a-gun! I can hear it two rooms away!

Other Thoughts: I would never purchase another SeaSonic Power Supply if they're all this loud.

Pros: Good, reliable power.

Cons: Needs more SATA, fewer Molex.

Other Thoughts: Who still needs a power supply with anywhere near the equal number of Molex adapters as SATA power?

I use this for a media server with 6 mechanical drives (4 WD Reds & 2 standard 7200rpm drives), an i3-3220, a few sticks of RAM, and an optical drive--- at first I was concerned that it would not supply enough power, but I'm pretty sure it will be fine. It's a bargain for a reliable media server with important data and lots of drives.

I ended up buying a second power supply (same one) for my backup server which is much less demanding, but I want the reliability that I had with my media server. If this can handle the media server, then I feel very safe with this in my backup server.

Pros: This is replacing a 5-7 year old Antec 380w power supply from the original Antec Sonata case (before PSUs were rated "80 plus"; etc). It used around 83w when basically idle and 100w-110w when in use (not including the monitor of course).
The Seasonic PSU is drawing only 60w at idle (probably 10w is heat since it's under 80% efficient at such low draws according to reviews). It hit 85w when doing a "quick scan" using Microsoft's free security software. I can't recall what I did to load the old PSU - might have been during boot up. 99% of the time I'm just reading stuff online so the idle power is key, as it is for 99% of us.

One other thing - the old PSU drew 5w even after selecting "shut down" in Windows. I did not select "sleep". I can't recall what it drew in sleep mode for sure but I want to say it was between 5-10 and settled to 5w after 5-10 seconds. Anyhow, it seems the standby power draws 5w. Power usage went to zero as expected when I flipped the PSU's switch (on the back of the computer) to "0".

The PSU's fan is quieter than the Antec but it blows less air. Might be iffy if this will be the only fan exhausting air out of the case.

Cons: 1. There is no PSU fan monitoring cable. Not a huge deal since I can't control it, but the old Antec PSU had one. I did not see this complaint in reviews. Last time I bought a PSU a few years ago, this was a feature people looked for.

2. Antec had 1 or 2 lower voltage "fan only" Molex connectors (for powering case fans) which were fantastic. They were controlled by the PSU - as the PSU sped up its fan, it also sped up the case fans. Even my Panaflow fan roars at 12V, so it seems I'll have to go back to using a fan controller or the 5V or 7V Molex modification/trick. Yea, I knew it didn’t have this feature, and I’m not 100% sure if anyone does. Antec probably does. Perhaps they have a patent is why it’s not standard across the industry?
One big problem is if a knucklehead tries to power something else with these special low voltage connectors, which could explain their absence.

3. As someone pointed out somewhere or another, there are 4 SATA connectors (2 connectors on each of 2 cables = 4). But it seems that all PSUs since the start of time put the two connectors (including Molex) too closely together. My DVD drive uses SATA and is 3/4ths of the way to the top (in the bottom 5.25” slot) of my fairly small tower (Antec Sonata) case. I can’t get the SATA connectors to reach the DVD drive as well as the top hard drive. They should have made one cable with this very common situation in mid or included an extension cable. Luckily I had a Molex to SATA convertor cable as I need all 4 SATAs until I transfer files to a new HD.
One SATA cable is longer (I think the distance to the first connector is longer, but the distance between the two connectors is the same on both cables). The cables are “buried” now so I can’t double check but you can find that info online. I saw the lengths in a review along with this same (minor but ridiculous) complaint.

Other Thoughts: My Antec was a bit heavier, but the cases are the same size - perhaps exactly the same. Antec was much less efficient (as were all PSUs back then) so it needed big heat sincs (can see them through the cooling holes). I have no idea how heavy/beafy this is compared to other modern PSUs, but since reviewers are impressed, it seems OK.

Old PSU won't start reliably - I assume it's related to standby power. The computer case has a date of Feb 2004 stamped on it, so the old PSU is around the same age. Got 8-9 years out of it at ~4 hours per day.

Been building PCs since 1989 - before the web (browsers) existed!

Pros: Great price, quiet, efficient, looks great, cables are well organized, came with lots of zip ties and velcro straps for cable management, everything about it is extremely high quality. Even the packaging was surprisingly good.

Cons: None

Other Thoughts: I never thought I'd be impressed by a PC power supply. If you need 360W or less, get this PSU.

Pros: This is a top quality PSU and it shows. It is the third Seasonic PSU I have used and where the budget allows it is the only one I recommend. I have two in my own units and one in a build for a friend. Seasonic PSU's are worth the extra few dollars on a component that many people try to cut corners on to save money.
This PSU is still really a good value for an 80 Plus Gold power supply. It isn't modular but I would rather give that up for the overall quality of the product.
This unit is whisper quiet and cool. I have this one in an HTPC and it cannot be heard from my TV cabinet in a Silverstone Gandia HTPC case.

Cons: Not one. It is good stuff.

Other Thoughts: Thank heavens I happen to have a couple of spare black screws on hand. I can imagine how terrible it would be to have chrome screws sticking out of the back of my case where I can't see anyway...I think it effects the voltage when you overclock the HDD Led.

Pros: 80 Plus Gold
Black Sleeved Cables
Black outer shell
Low Wattage
5 Year Warranty

Comes with a bunch of cable ties and zip ties.

Cons: Emanates a small amount of coil whine.
Does not come with black screws.

Other Thoughts: Reduced the idle of my home server from 45 watts to 39 watts and full load from 87 to 73 watts.

Cables were a little on the long side for my small ITX enclosure and have heavy duty cables which made them a little hard to maneuver but the quality compensates for that.

Pros: Great powersupply; quiet, efficient, and components are of good quality. I trust it with my mission critical new computer

Cons: None whatsoever! A slight reduction in price would be nice but this is a high quality power supply!

Other Thoughts: AMD FX-8350 Eight-Core CPU, 16GB RAM, Geforce GTX 550 Ti AND a Radeon HD 4350, WD VelociRatpor 10K 300GB hard drive, many fans and stuff!

Pros: Looks nice
Sleeved cable are clean

Cons: The unit emits a high pitch whine when plugged in and turned on (before PC is turned on). It's really really annoying and is driving everyone in my house insane (especially my dog who I imagine it is torture for). I read reviews and seasonic is supposed to be good but I've had better luck with my corsair AX series units. Thankful for newegg's RMA being quick and easy. This one is going back and I'm not ordering another. Will go with another corsair unit or this one (http://www.newegg.ca/Product/Product.aspx?Item=N82E16817703034) that gets even better reviews and is a bit modular too.

Pros: Can actually power up to 450w nuff said.

Cons: none
