5 out of 5 eggs660 titanium

This review is from: Seasonic SS-660XP2 ATX 12V/EPS 12V, 660W, 80 PLUS PLATINUM Full Modular certified Active PFC Power Supply New 4th Gen CPU Certified Haswell Ready

Pros: Can't hear it and its on the standard fan setting in a case that is not meant to be quiet. Seasonic rocks in case you guys haven't done your research.

Cons: Pretty tight connectors. Felt like I was going to break my motherboard plugging it in...

5 out of 5 eggsPlatinum Beauty

This review is from: Seasonic SS-660XP2 ATX 12V/EPS 12V, 660W, 80 PLUS PLATINUM Full Modular certified Active PFC Power Supply New 4th Gen CPU Certified Haswell Ready

Pros: Beautifully simple design
Fully modular
Platinum 80+ and heavy
Flat cable management...small caveat
I like the choice of modular cables. My last modular power supply didn't have more plain cables. So I ended up having to plug to 6 + 8 pin connectors to use two 6 pin connectors.

Cons: A lot, and I mean a whole lot, of flex in the modular base. Trying to plug in the motherboard cable took a few minutes and there was a lot of give. It barely clicked in and I thought I was going to break it.
The flat cables were a nice touch but the 24 pin connector was still wrapped like traditional wires. Just doesn't match.
I wish I had a choice of plain 6 pin connectors for my GTX 680 and not 6 + 2. But it's just a nit pick. I probably could get some aftermarket ones, I just don't like the look of hiding the extra +2 connector.

Other Thoughts: The flex when I plugged the motherboard cable in worried me. I wouldn't have been as worried if it just plugged in but the pins wouldn't budge in until I gave it a lot of force and then POP...in they went. It's only once I'll have to deal with it, but I would have liked if the cable just plugged in.
Other than that one experience. It's been masterful so far. Coming from a 750W bronze to 660W platinum and I love the idea of being so much closer to 100% efficiency. Got this on a huge sale dropping the price from $160 to $70 with the rebate. It was a great deal, but I didn't see myself spending the full price for a 3 year old design. As I have no performance issues under full load, there is no coil whine or any audible noise, and a seven year warranty, I'm leaving this at full 5 eggs. It's an awesome power supply. If it's on sale, or you have the means, get it. Highly recommended. Especially because it's one of the few brands that can design and manufacture their own power supplies.

5 out of 5 eggsSo far so good

This review is from: Seasonic SS-660XP2 ATX 12V/EPS 12V, 660W, 80 PLUS PLATINUM Full Modular certified Active PFC Power Supply New 4th Gen CPU Certified Haswell Ready

Pros: Totally silent, no coil whine for me as of yet (just over a month of ownership). Plenty of modular connectors to choose from and it seems well built.

Cons: None thus far.

5 out of 5 eggsPhenomenal

This review is from: Seasonic SS-660XP2 ATX 12V/EPS 12V, 660W, 80 PLUS PLATINUM Full Modular certified Active PFC Power Supply New 4th Gen CPU Certified Haswell Ready

Pros: This is absolutely the quietest and most efficient power supply I've ever owned. I don't think I've ever actually heard the fan spin up at all, even at 60-70% load.

Cons: Absolutely none. Seasonic always makes quality units.

5 out of 5 eggsExcellent PSU

This review is from: Seasonic SS-660XP2 ATX 12V/EPS 12V, 660W, 80 PLUS PLATINUM Full Modular certified Active PFC Power Supply New 4th Gen CPU Certified Haswell Ready

Pros: -Exceptionally efficient (90%+)
-Fully modular with plenty of cables means that you have a lot of flexibility for your build, even in a smaller case.
-Completely quiet. Can't hear it all.
-Fan doesn't spin unless I'm really putting load on my system (I checked)
-Comes with a nice case for the cables and a bag for the PSU.
-Clear documentation.
-Build quality is solid.
-Sleek design and dark colour.
-Trusted brand

Cons: Absolutely none. It's been reliable so far.

Other Thoughts: The one I bought was 660W which is more than enough for most builds (including SLI with GTX 970s and 980s). It's been amazing so far and I'm glad I went Seasonic.

1 out of 5 eggsVery Disappointed

This review is from: Seasonic SS-660XP2 ATX 12V/EPS 12V, 660W, 80 PLUS PLATINUM Full Modular certified Active PFC Power Supply New 4th Gen CPU Certified Haswell Ready

Pros: Great specs, great price (when on sale), fully modular, hybrid fan, etc.

Cons: Noisy circuitry!!! This might be a platinum certified PS, but it sounds like it is struggling to fight off brown-out conditions all the time. It makes more noisy as the electrical feed becomes less perfect. Not a good design...inside that is.

Other Thoughts: I should have listened to the reviews! Mine is no exception and the coil buzzing is very annoying. I have tried three cheaper PSs in the same machine and they are far less noisy. I am going back to a Corsair CS450M until this is resolved.

I will try a different UPS as others have mentioned, but it still makes noise bypassing the UPS. Oddly enough the platinum PSs make more noise than the gold and bronze models I have on hand.

Manufacturer Response:

Hi John,
Sorry for the noise issue but please enable all energy saving modes in your BIOS and this should resolve your issue. Often times it is the combination of the DC-DC PSU platform and the ErP settings of the MB that can cause the PSU to make coil whine noises. If the issue persists, please contact us at newegg@seasonicus.com and we will try to resolve the issue for you. Thank you.

This review is from: Seasonic SS-660XP2 ATX 12V/EPS 12V, 660W, 80 PLUS PLATINUM Full Modular certified Active PFC Power Supply New 4th Gen CPU Certified Haswell Ready

Pros: One of the best PSU in the market.
Fully modular.
Got a great deal when they had it on sale.

Cons: Connectors fit in the PSU kind of tight, doesn't go in all the way unless you play with it a little.
