My old 600 Watt enermax need replaced. I want a good psu with at least 750 watts. I need enough connections on it to plug into my AMD Phenom II x4 955 3.2ghz and also 1 hard drive, 1 DVD drive and also 2 6pin connectors for a 460 gtx video card oh and 2 case fans 1 liquid cooling system. Im clueless as to what to buy.

750 watts is kinda a "in between size as 650's wind up in most single card systems and 850's in most twin gfx card systems. As the 750's are so close in price to the 850's, I generally go with the 850's. However, with the power requirements of the 460, you could get away with adding a 2nd 460 in the future using the "Antec TP-650 New" or the "Corsair TX750" ... The TX650 is not certified to run twin 460's. With the water cooling, I'd bump it up 100 watts.

For comparison purposes , the list below contains performance ratings (10 scale) at jonnyguru.com / prices as per newegg on 12/31/2010 and ones w/ double asterisks (**) made it onto silentpcreview.com's Editor's Choice List meaning they excelled at both electronic and acoustic performance:

850 watters

Antec SG-850 - 10.0 ($250) **
Antec CP-850 - 10.0 ($120) **
XFX 850W Black Edition 10.0 ($130)
Corsair HX850 850W - 10.0 ($170)

Antec TruePower Quattro (TPQ-850) - 9.5 ($150)
Corsair TX850 - 9.5 ($130)
Seasonic M12D 850W - 9.5 (NLA) **
NorthQ Giant Connector 850W - 9.5 (NFS)
Etasis ET850 - 9.5 (NLA)
Silverstone Zeus ST85ZF - 9.5 (NLA)

Enermax Revolution 85+ 850W - 9.0 (OOS)

Thrmaltake Toughpower XT 850W - 8.5 (NLA)
OCZ Z Series 850W - 8.5 ($165)

NorthQ Black Magic Flex 850W - 8.0 (NFS)
Coolmax CTG-850 - 8.0 (NFS)

SilverStone Decathlon DA850 - 7.5 (NLA)
Enermax Galaxy DXX 850W EGX850EWL - 7.5 (NFS)

SilverStone Strider ST85F - 7.0

Silverstone Element ST85EF 850W - 6.0

650 watt power supplies.

Note: Just because you see a brand name on this list, never make the assumption that their other lines are of matching quality. Silverstone for example has other models w/ 6.0 and 7.0 ratings.

Antec Signature 650W (10.0) OOS **
Seasonic X-650 650W (10.0) $135 **
Silverstone Olympia OP650 (10.0) NFS

Thermaltake Toughpower QFan 650W (9.5) NLA

Antec Earthwatts EA650 650W (9.0) $50

Antec True Power Trio 650W (7.5) NLA

XFX XPS 650W XXX Edition Power Supply (7.0) NFS

Antec NeoPower Blue 650W (6.5) NLA

BFG BFGR650PSU 650W (6.0) NLA

NorthQ Black Magic Flex 650W PSU (5.0) NFS

OOS - Out of Stock / NFS - Not For Sale / NLA = No Longer Available


So, in conclusion, if ya just going to use 1 GFX card, the Antec EA-650 would be my choice...... f ya wanna set aside some power for a future addition of a 2nd GFX card, assuming mobo has the capability, I'd get a XFX Black Edition 850 as it's only $20 more than the TP-650 and $10 more than the TX-750

Is this the antec ea you are talking about? http://www.newegg.com/Product/Product.aspx?Item=N82E168... would that be able to support my Phenom XII, my 460 gtx card(which requires 2 6 pin plugs) my dvd drive, hard drive and liquid cooling system?

Or is this the one? http://www.newegg.com/Product/Product.aspx?Item=N82E168...

well my computer is killing any video card within minutes of putting one in, its killed 5 so far. I had the motherboard tested by the manufacturer and it was fine, the enermax however tested fine too but it had something wrong with the 5v dropping off. I was told that the power supply was fine with this happening but someone on these forums pointed out that if that was happening then more than likely the power supply is overcharging and causing the cards to fry so I need a new power supply.


And to the guy who suggested the Antec Earthwatts ea650 there are 3 types, this one http://www.newegg.com/Product/Product.aspx?Item=N82E168... and this one http://www.newegg.com/Product/Product.aspx?Item=N82E168... and this one http://www.newegg.com/Product/Product.aspx?Item=N82E168...

no, Seasonic is a good brand. They also make a lot of the PSUs that have the Corsair brand, as well as others. :D

Alright I purchased that TP-650. With the 40 dollars instant coupon it was only 89 which I personally find a steal seeing some of the great reviews its gotten. Everyone pray for me that it actually solves the issue with my computer killing my video cards :(
