Evga Release Classified SR-2 Power Supply

"Evga have brought out a strong power supply to pair with their workstation-class motherboard."

Search News

Evga have announced the release of a new power supply, the Classified SR-2.  Intended to be paired with (though certainly not restricted to) their workstation-class motherboard of the same name, the SR-2 power supply is capable of putting out a top-notch 1200 watts of continuous power.

Though Evga touts the unit as being specifically designed around SR-2 motherboard, you can quite clearly see the name "Truepower Quattro" on the packaging.  Thus we can tell it is simply a rebranded Antec Truepower Quattro OC edition with a few tweaks.  The most obvious tweak is in the connectors, with a whopping 15 PCI-E connectors (12x 6+2-pin and 3x 6-pin).  These additions were required the sacrifice of two SATA, three molex, and one floppy connector though.

Key features include an adjustable 12v rail voltage pot and fan controller, as well as Antec's PowerCache technology.  PowerCache involves the use of a 2200µf capacitor wired inline with the CPU and video card connectors to ensure sufficient power is available when needed.  The unit provides six 12v rails capable of putting out 38A each and pretty much all of the connectors you could ever need.

The Evga Classified SR-2 Power Supply is priced at $359.99 from their online store, though one would imagine we'll see a lower price at actual retailers.  The unit comes with a standard 5-year warranty.

So I just realized that for the past couple of years I have been running at x8 on my PCIe.... So I switched it over to x16. I haven't done any tests or anything but am I likely to see a performance increase from my video card, will it be significant?

Thanks. :)

Depends on the GPU frag tbh, if its a monster designed for PCIE2 then yes, otherwise it will be minimal if at all.

I don't know a great amount on the situ Frag tbh but I did do a lot of reading before I decided on a Crossfire board about this stuff.

Apparently when shared into two 8x lanes you lose at most 10-15% of the overall raw power that you would if you were using twin 16x. At the end of the day I could not justify spending £130+ on a motherboard with twin 16s when I could get one that shares into 2 x 8 for £30.

For some boring figures? Well, a Crossfired 5770 test bed in a review here scored about 17500. That was with an I7 and all sorts. My machine (940 3gb ram) 5770 Crossfire scored 15500.

considering you have a 4870 - you will see little difference. pcie 2.0 x8 is the same as pcie 1.0 x16. there is plenty of bandwidth for it. but run it at x16 just cuz u can :D
