Actually i think im gonna stay above 620W... Been told the quality units are around that wattage usually.

That is actually false. Power supply output wattage or efficiency mean very little to nothing as far as quality of the unit. The PSU you propose would indeed work, but a quality 550 or 500watt should be just fine for any single card or pair of Nvidia 6xx series cards. For some future proofing or for a possible move to a dual-card AMD 79xx series card, the 750 you propose is a better idea.

Ok. Last question : XFX XXX 750W Silver efficiency semi modular vs XFX Pro 650W bronze efficiency semi modular?

Only £4 in it and 9A difference.

These are both Seasonic designs, like everything XFX currently sells.

The 750W model happens to be better and higher-end, so get that. It's not like two power supplies of the same series where the higher-wattage part just gets an upgraded component here or there. The 750W silver is M12D, which a few years back was arguably the best out there.

Yeah, I know they're the same model underneath... But for example, I heard that the TX650 was much louder compared to the XFX equivalent... That's what confused me a little bit, unless they just use a different fan.

Both the XFX's have the same 5 year warranty with a 2 year RTB to Scan (for free!) The corsair TX650 had a 5 year RTB.

ugh, I knew I should've reworded that. Maybe you take some blame too?

I said the opposite. They're different designs.

The Corsair TX650 V2 (the current TX650 is another different unit) uses a different fan and possibly fan speed control scheme, as compared to the equivalent XFX Core 650W and XXX.


XFX XXX (discontinued) 650W 80+ bronze semi-modular is some kind of custom, mostly similar to old S12E.

XFX Core Edition 650W 80+ bronze non-modular is SS-__AT, same as Corsair TX V2 and NZXT Hale82 (modular, original, not the N), Seasonic M12II (new, 650W+, not the 620W and below). XFX XXX Edition (newer models) 650W 80+ bronze semi-modular is also SS-__AT.

XFX Pro XXX Edition (also the discontinued Black Edition) 750W 80+ silver semi-modular is M12D, better than all these others.


Actually, all this renaming and rebranding, on top of the EasyRail crap (and times when "single rail" units aren't actually so) makes me want to smack XFX marketing...

Alright, thanks! I'll take some of the blame :-P

So is the XFX 750W XXX silver semi modular the best Psu for me?

I bought the XFX XXX 750W. However, I've just found out that after Scan's 2 year RTB, I would have to deal with XFX (EU) directly if i had a problem....

Does that sound ok or is their customer service still really bad? I mean, I reckon I'd be able to buy another from somewhere for temporary use if i had to send my current one off for a bit (I heard that xfx is pretty slow)

I could get a different power supply from somewhere like OCUK if that's a good idea? The same one is £90 there...

Decided to stick with the one from scan. Installed it today and everything is so much quieter. Now I'm gonna have to think about changing the case fans and quietning the hard drive somehow.

I have noticed that the psu fan doesn't tick :-D bit after a bit of use sort of whirs? I guess this is just the fan which I heard can be lubricated poorly - so I might try pushing the fan in a bit... Which apparently helps. Although I'm not sure if im being overly picky now :-P
