    Question about power supplies and reviews

    Hi Guys,

    Long story short my PC is about to change spec wise for a number of reasons and the one thing I feel I should have done last time around but didn't was put a more powerful PSU in there (especially as I am now running SLI 780's and I'm now moving to a 4790K that I plan to overclock), anyhow...

    Looking for a 1000+ Platinum supply and there's obviously loads out there so I started looking in to reviews, but I am finding so many disparities between the review sites it's hard to tell what the truth about a particular supply is...

    My question is which site is the more reliable for PSU reviews? Just when I think I've found the supply for me I read another review on another site and find myself questioning my decision

    Help?

    R.

    Because even with todays efficient PSU's, they're still best at about 50-60% loading, so that 600w draw you measured is about perfect for a 1000w capable unit. I do see what you mean about expense, but if you're into your mods you can pick a dell 1000w server-rated unit up from ebay for about 40 quid, tenners worth of rewiring work and you've a decent 1000w unit for the same price as most 400-500w units...

    Forgot to post back, in the end I've used an HX1000i purely because the 1200 P2 wouldn't fit in the case, I'd already ordered the HX before I saw the 1200 P2 so was about to send it back (glad I didn't now), it's working lovely. I've dropped a couple of hundred watts but I doubt I'll be hitting 1 Kw any time soon

    The idea that more is always better, especially after a PSU failure. That and then there's the longevity of an overpowered unit that barely has to do any work

    I got mine after melting an 800W unit twice despite the fact that the rig at the time shouldn't have ever pulled more than about 650W. First time it lasted a month and just stopped working, the replacement lasted nearly a year then decided to leak goo all over itself (I made the mistake of thinking a 90 PSU with at least 100W headroom would be sufficient but now I know: never buy Xilence PSUs).

    That was about 7 or 8 years ago, and I'm still using the Antec Quattro modular 1kw that I bought to replace it. The thing's like new, never skipped a beat, always cold (managed to get it to feel slightly warmer than room temperature by running SLI). Don't have to worry about whether I'll have enough juice for any upgrades or overclocking either. Yes it was 150 at the time, but considering how often I've had to replace supposedly decent and powerful PSUs in other people's computers; I'd say it's 150 well spent (roughly 20 a year so far). I'm hoping it lasts another few years yet too...

    Do I need 1000W? No (500W would probably do at the moment). Will I ever go for a lower powered unit after using this behemoth? Not in my rig... Do I want a rock solid PSU that lasts for ages and keeps my system running without skipping a beat?

    Damn thing weighs more than the rest of my PC combined like, but it's not like I'm lugging it around all the time

    My Ax860i never struggled with 2 780s and a 3930k, most I ever saw it pull from the wall (totally unrealistic forced stress test of p95 while folding) was around 600w.

    Not sure why 1000w+ PSUs are so popular tbh, crazy expensive and 99% of the time totally unnecessary

    Thanks Lee, I did just that, and on the back of its amazing results and reviews I've ordered one (actually ordered the 1200W as the deal was good).. Somewhat more power than I actually need right now, but It'll last me a good while and with that warranty I'm good to go Thanks for the recommendation!

    Have a look at the EVGA Supernova P2 1000W if you already haven't. I would say that this platform is one of the best around for the price/performance. It is built by Superflower and based on the Leadex platform. You also get a very generous 10 year warranty. This unit also features eco fan mode similar to that on the HX1000i.

    IMO of course.
    agreed, guru3d too and techpowerup

    as others have said, a sample of reviews is good rather than relying on one, however, having a comparison where tests are performed in the same environment and with the same testing methodology should not be discarded lightly

    HX1000i, was originally thinking of going to the AX1200i but from what I've read it'd be hard to justify nearly 100 more for it.

    Which psu are you considering?

    Johnnyguru usually does the best breakdown of the actual guts of the PSUs, telling you who the OEM is, what caps they used, all that sort of thing. I do trust him the most for PSUs, but then he specialises in PSUs whereas most of the other sites here are reviewing a wide range of components so they can't be expected to have the same level of specialist knowledge (or equipment).

    But it's true that it's always worth checking a few review sites.

    i normally read reviews from many sites and then just make a decision on them all. I trust some sites like oc3d, ttl just tells it how it is! techpowerup are good too.
