psu to power 2 evga 680 hydro classifieds when they come out

[The Goose]

Hi guys,as the title suggests im looking for a new psu that can power 2 evga 680 hydro classified`s due for release which ive read will be 8+8 pin,at the moment im leaning towards an Enermax ERV1250EGT 1250W Revolution 85+ PSU,i`ll also be running either an i7 3930 or the 3970 ,2 water pumps, 6-8 fans,2 hdrives and dvd drive,fans will be controlled through 2 4 channel fan contollers and maybe some led strip lights
what do you guys think,i know 1250 watts will be more than enough but its the brand,reliabillty and reputation im more concerned about

My experience with Enermax is "dated" -- I've not used them for 8+ years. I stopped using them because the products were worse than bad. I used them in alot of customers pcs that I built because a local shop had them cheap, and was that ever a bad mistake. If I recall correctly, three of them popped within a month of purchase.

Things could have changed alot since then, but I'll never ever ever try the brand again.

The hydrocopper waterblocks aren't the best and have had a number of issues with vrm cooling in particular. According to evga they are working on a fix but I'm not sure if one's been implemented for these. You might be better off buying the block separately or if you want it all pre-fitted then I'd look at the one's from OCUK that come with EK waterblocks.

For the psu I would look at the seasonic 1kw, the toughpower 1000w or the corsair hx1050. The hx1050w is probably the better price/performance psu of the lot. Having said that the Enermax ERV1250EGT Revolution is an excellent psu but components are getting more power efficient so 1250w is probably not needed but could be a safer alternative in the long run. Though at £230 it's a little overpriced tbh, for £200 you can get a corsair ax1200w which is probably a better unit overall.

Thanks, the corsairs appear to only have 1 single rail whereas the enermax has 6 12v rails and is only 10-15 pounds more in the uk not sure how correct that is what ive read about the corsairs

ive been running a Tagan BX1300 for over a year now and its been faultless but only has2 x 6 + 8 pci-e and 1 6+6 pci-e

I think one of those will be enough. (basically the same internals like corsair hx, probably less prone to coil noise if the coils are made by seasonic)

1000watts is overkill for a 680. this is all you would need

seasonic X850. TDP of the evga hydro copper 2 is 180~ watts, you could run quad sli if you wanted on a quality 1000watt

or if you want to spend the extra 20$ for the seasonic 860watt platinum

Yes it's 6x 12v rails, which generally wouldn't be a good thing as normally it would limit the amount of power that can be supplied to components based on the rail in use however it seems the enermax unit lived up to it's name.

They moved the entire DC to DC circuit up on the daughter PCB

found at the front side of the unit. The asymmetric hybrid DC to DC topology and the synchronized transformer design Enermax are using allows this PSU to distribute its power to any voltage lines and in any way necessary, unlike many other units which require to be loaded according to the ATX specifications or the Intel design guide in order to operate properly.

Unfortunately real world systems rarely ever follow the rules, but potential buyers of the Revolution85+ will be happy to know that this PSU ignores those rules completely and it can place any load necessary on any of its lines. This allows it to operate smoothly even if half of the product's lines are operating at maximum capacity while the rest are down to 0A.

above taken from a hardware heaven review.

The corsair unit however provides all it's power on a single 100.4 amp rail and this seems to be the preferred design recently, especially when using multiple graphics cards. Having said that the enermax unit seems to be one of the first units to provide almost all of it's power on the 12v rail so comes in at 103 amps also.

Overall though the corsair unit seems to be very well regraded according to jonnyGuru's review. It averaged 90% efficiency at load states above 200w and he considered it the best unit he ever tested.

Overall though they are both excellent and the extra £30 or so gives you an extra 3 amps 12v/ 50 watts.
