New PSU

post #1 of 9
Thread Starter 
Okay so my PSU sucks, I don't feel like its going to blow up or catch on fire anytime soon. However it does occasionally squeal, doesn't support X-fire which some day I would like to do when my 280x isn't good enough, I would also like something that is quiet and ideally has a fanless mode. Now I looked on the 'approved PSU list' essentially I just got confused as it was a long list, so I decided to post here and ask the experts!

Ideally my new PSU will be able to:

- Support crossfire, so have enough wattage and PCI connectors
- Be at least semi modular, however I enjoy cable routing and so fully modular would be better
- I would like it to be as efficient as possible
- And finally be very quiet, preferably fanless during idle

Buying from the UK, and don't really have a budget, but I would like to keep it under £200 as otherwise the money could be better spent elsewhere.

EDIT: Also a good warranty would be good.

There's no such thing as a PSU not supporting Crossfire or not supporting SLI. What matters is, having enough power (and enough connectors, but you can use Molex to PCI-E adapters).

 

Having said that though, the CX600M does not have enough power to power your system with two 280Xs in it. For that, you would want a good quality-made 950W PSU or higher. However, if/when the day comes when a single 280X isn't enough, you will be able to find another single video card to upgrade to that will be as good as or better than two 280Xs in Crossfire while consuming a lot less power than that. Plus, when that time comes, the 280X cards will be kind of hard to find.

Good then my understanding was correct. Crossfire is just an option I would like to keep open, but it is unlikely I will be able to upgrade anything big in the next 3 years, due to studies.

Essentially I want something like this Antec high current pro platinum 850w, but didn't know if there was any other alternatives, with a fanless mode? And was wondering what you guys think of it.

That's a great PSU, but would you ever need all that power? 3 years from now, you'll be able to upgrade to another single video card and get a huge boost in performance.

Its overpriced a bit and its multi 12v rail system can give you problems if you are overvolting your video cards, Cooler Master V or the EVGA SuperNova G2 are pretty much the best single 12v rail options out there

No but at 50% (Probably what my system uses on full load) and 25% usage its 92+% efficient, and the support is there if I want to crossfire. However ideally the PSU would have some features such as be quiet! Power Zone 850W Modular PSU which powers 3 fans for 3 minutes after the system is switched off, thus components are properly cooled or like the Seasonic Platinum 760W Full Modular PSU has a silent mode, or something else which is just cheaper, I don't know lots about PSUs so appreciate the input!

That 50% load thing is for your average load, not your peak. If your absolute peak is at 50% and you only reach that peak for a few hours per day, then your average is WAY below 50% and that's not good for efficiency. Not good at all. :/

 

If you won't be upgrading for at least another 3 years, then you definitely won't be adding another 280X. You'll just upgrade to the whatever equates to today's 280X or 290 or whatever you can afford at that time. The 280X by that time will be too hard to find and the single-card options in your price range will be superior to two 280Xs in Crossfire.

I couldn't find the G2 on amazon or scan but the V700 at £130 inc P+P is ideal thanks a lot, +rep to you both.

Overclockers have the Super Flower Leadex which the G2 and P2 are based on
