alternative 750W PSU to XFX p1-750x-xxb9
HI All

I ordered an XFX xxx edition 750w PSU (p1-750x-xxb9) semi modular 80 plus Bronze from amazon for £78.50. The company who supply the PSU to amazon said they had a stock problem with this particular PSU.
They offered a Corsair CS750M PSU saying it is better as it is 80 plus gold not bronze, however after reading this forum it appears the CS series PSU's use bad caps whereas XFX are made by Seasonic so I don't believe it is better (tell me if you think otherwise).

If I can't get the XFX I was thinking of getting one of the following PSU's:

Evga SuperNOVA 750W fully modular 80 plus Gold (220-G2-0750-XR)- for £80.76

or for a bit more

XFX ProSeries (Black Edition) 750W fully modular 80 plus Gold (P1-750B-BEFX) - for £94.99 - (updated)
Antec HCG-750M 750W semi modular 80 plus Bronze (HCG-750M GB) - for £96.85
Corsair AX760 fully modular 80 plus Platinum (CP-9020045-UK) - for £114.99

Please advise me on which PSU I should get, feel free to advise other PSU's. As long as it is 80 plus (don't mind whether it is bronze, silver, gold, platinum as this is to do with efficiency not reliability) and is around £80 - £110

Good choice and at least you still have the option for sli.

Decided - Ordered the Evga G2 750W as I probably won't bother with sli anyway.

Also thanks everyone for all your help

This one is a good choice as said and will be enough imo to support sli of gtx 770 when you use a cpu from the 1150 socket.With an amd FX or 2011 would i get the 850watts version too,these just use more power.

Just pick one. They are both very good units. Please stop bumping the thread Lol... Get a 650 w or bigger for one GTX 770, 850w for two GTX 770.

Just looked on NewEgg and it sais the Evga is intel 4th gen compatible and has 4 molex connectors

also would 750w be enough if I ever wanted to sli the gtx 770 with an i5-4690k?


I would recommend the 850w EVGA G2 for sli 770s.

Just do a little research for the PSU you want to buy... Vendors like Newegg clearly show if a PSU is "haswell compatible".

The XFX ProSeries (Black Edition) can be rulled out as it would actually be the newer XFX XTR series unit because it has the same product code which I don't think is as good.

Between the XFX xxx edition and the Evga I will probably get the Evga, Also I want to know does the Evga come with a Molex power cable and is it Haswell Ready?
