Deal of the week: Corsair power supply bargains

Good power supplies aren’t cheap; those who disregard that fact can subject themselves to high noise levels, low efficiency, instability, and potentially catastrophic failures. On rare occasions, however, normally expensive PSUs can be had well below their normal asking prices. That’s exactly what’s going on at Newegg today: the e-tailer is offering rebates of up to $45 plus free shipping on Corsair power supplies.

The promotion applies to Corsair’s 750-watt CMPSU-750TX, for instance, which is on sale for $109.99 shipped instead of $139.99 and comes with an additional $10 mail-in rebate card. Similarly, you can grab the 650W unit from the same family for $99.99 shipped instead of $119.99 and pull the price to $79.99 with the included mail-in rebate form. Both units have five-year warranties, multi-GPU support, and big 140-mm cooling fans.

Folks on tight budgets may enjoy the 400W CMPSU-400CX, which Newegg now offers for just $50.99 shipped instead of $64.99—alongside a $15 mail-in rebate card that can take the price down to a cool $35.99. This particular model doesn’t have too many frills, but it does feature a single meaty 12V rail, 80 Plus certification (implying efficiency of at least 80%), a quiet 120-mm fan, plenty of neatly sheathed cables, and a three-year warranty. Corsair even includes some cable ties in the box.

    620HX is good enough for me for now.

      That’s what I’ve been using for the past few years as well, the 620HX. I can’t see *most* people needing more than that. Modular, quiet, 84% eff, 600W rated on the 12V line and was reasonably priced when I bought it. Corsair offers many other great PSUs from everything I’ve read, even if tweaked (for the better) re-brands (with a better warranty) from some of the best suppliers. Good choice to single them out for a deals post!

      Can’t praise Corsair’s support enough either. I don’t know if RamGuy (I think that’s his handle) is still around, but he’s a top notch guy from everything I’ve seen on their forum. When I checked it out back in the day, he seemed to right every wrong, and most everyone with a problem seemed contented.

      All I’ve ever needed was a 8-pin pci-e cable, as they used to ship with just 6-pins, but he got it to me post-haste and without expense.

    Having done some memory RMAs with them in the past, I can vouch for their warranty support being pretty good.

    The psus themselves not being junk is pretty well established on the web by now.

    5yrs standard, 7yrs on some of their PSUs is pretty nice. I recently crammed a modular with a 140mm fan in a uATX case, it wasn’t cheap but after having had two other brands recently die right before the 3 year mark I figured why not.

    (and they were babied on UPSes their whole life too! Thankfully died within the 3yr coverage but replacements now power less critical stuff I won’t keep that long anyways)

      My TX650W is jammed into a uATX case as well. I’ve got it all routed to sit in an empty 5.25″ bay. Kind of funny to look at; the best way to use this PSU seems to be in a big PSU-on-bottom ATX tower.

    I can say for sure, I am satisfied with the cx400. Had it for almost a year now.

    Have both the HX520 and CX400. Both are amazing PSUs with the 520 powering a 4850Xfire setup for over 2 years solid. The CX400 for is extremely quiet and powered a 4850 system easily. Corsair is a great company.

      • derFunkenstein

      4850 hasn’t been out 2 years solid, let alone been in Crossfire in your system. :p

    For any of you wondering, Corsair probably has the best mail-in rebate turnaround times I’ve seen. I sent in a MIR for a 650W power supply of theirs and got my $20 cheque in under two months. A lot snappier when you compare it to the 8-10 months it took Auzentech and Visiontek to send me money ๐Ÿ˜‰

      They were also the easier and quickest for RMA’s that I’ve ever dealt with. Top notch company.

        • Suspenders
        • 10 years ago

        Haven’t had the “pleasure” of doing an RMA, but yeah, from everything I’ve seen they are definitely a top-notch company.

    • bdwilcox

    Those aren’t very good prices. Just wait a couple days until TigerDirect has their 15% Bing cashback and you’ll beat those prices with no mail-in rebate hassles.

    I think my PSU have strange noise somehow.. it’s 750w Thermaltake Toughpower ( the first version)… it’s very quiet most of the time… just sometime there’s like electrical noise, almost buzzing like.. it’s not loud but noticeable… quite annoying in fact… dont think fans make that noise… i’m not 100 percent sure it’s the psu.. anyone knows why? and i dont think my setup can even use 500w… i just wanted extra power for when i upgrade in the future…

      • Welch

      The high pitched tone your hearing could be any number of things nearing the end of their life inside the PSU (Transformer most likely, and not the kind that run with “The Beef” either)

    • JoJoBoy
    • 10 years ago

    If I recall my CMPSU-650TX come with a different 120mm fan which is quieter than the 750W version. Also both of those psu have been at those prices for weeks now.

      Moo? The 650TX is super quiet in my system. Is the 750 really that bad?

        • w00tstock
        • 10 years ago

        Yes, it is quite possibly the only computer part I have ever regretted buying, and I bought a gforce 5900. at idle it is louder than antec tricool 120mm on the 2nd setting (all 5 of mine combined), at load its just loud. Color me unimpressed.

          • Kulith
          • 10 years ago

          What?? I have one and it’s not loud at all…

          … at least I can’t hear it over the antec 900 fans

            • derFunkenstein
            • 10 years ago

            Well after some research it appears he might be quite correct depending on load. If you’re not loading more than 50% load, it’s pretty quiet. If you get much over 50% the fan really starts to ramp up. If he’s got dual high-end cards in Crossfire/SLI then he might be pushing it hard enough to ramp up.

            ยง[<http://www.pcper.com/article.php?aid=474&type=expert&pid=6<]ยง The huge leap going from 450 to 525W especially, that means the fan is really cranking at that point and would be quite loud. FWIW I don't pull more than 250-275W from the wall at any given time, which doesn't ever get the fan going (the CPU fan on my CoolerMaster Vortex 752 gets much louder).

            Reply fail?

            But still, it seems like it wouldn’t be too unrealistic to expect a PSU to survive a UPS, would it?

            Yep, except the OEMs claimed their PSUs were not subject to that. They asked various things before cutting me a check and shipping a refurb.

            Corsair has already confirmed on their forums as well that their entire TX/HX w/active PFC line does not care either.

            Also two of my UPSes are the high end variants (sinewaves for datacenter) I rescued from liquidations for pennies on the dollar even though they were NIB. Granted, its varied what is plugged into what over the past few years but none of my UPSes have died.

            My power isn’t bad either, I don’t run any ups in 100% line correction mode. They’re only for the *outages* like the frickin blizzard and windstorms.

            • w00tstock
            • 10 years ago

            Yeah, sure I suppose it would be fine if you don’t want to use more than 50% of the rating… Sigh. My system probably uses around 500 watts or so full tilt.

            • jimmylao
            • 10 years ago

            With a system taking that much power, I’d probably go for the 850. A system taking 500W from 850W is 58.8%. Now if you factor in usage and say a 5% power drop/year from power supplies because they lose their efficiency (is that a good drop estimate?). Then in the 5th year of usage you’d be around 75% usage, which I don’t think you want to stress your PSU above X% right?

            I don’t know.

            In any case, 1.5 years ago during black friday, I got the 750TX from Newegg for $75, which I knew from calculations and reviews that it would never go into the turbo jet turbine whirl, so I got that instead of the 650. Not a good deal.

      • NeelyCam
      • 10 years ago

      Yeah no sh*t. PSUs are so oversized.

      That 400W PSU looks pretty decent but even that one is way too powerful for modern-day i5-6XX/i3-5XX setups.

      Give me a PSU that runs at 80+% efficiency at 20-80W load with zero noise, and I’ll buy you a drink.

        • OneArmedScissor
        • 10 years ago

        The retarded thing is that several of them exist, but you can’t seem to buy them. Someone posted links to a few that are on the 80 Plus site a while back, but I’ve yet to see a single one for sale.

        Power bricks make more sense for most computers than any super efficient ATX PSU ever could, but since new graphics cards are still allowed such “generous” TDP levels, even if they really don’t need so much power in general use, that screws the whole system up.

      • continuum
      • 10 years ago

      I’ve used more Corsair 750TX’s than you can shake a stick at, and they’re all pretty low-noise at idle and typical load. Granted when the dual 4870’s crank up to full power, noise goes up, but who wouldn’t expect it?

      They tend to be universally more quiet than all of the PCP&C Silencer 750’s I’ve installed as well, although to be fair it’s not an equal comparison as the PCP&C units have *NOT* been installed in identical situations.
