Corsair or Antec?

[Kekewy]

I'm looking for a new PSU, while I'd prefer a gray one, need outweighs aesthetics at the moment. I've narrowed it down to two choices, one is an Antec, the other is Corsair. The Antec is a CP-1000 and the Corsair is a CMPSU-750HX.

The Antec is a much higher wattage for the same price as the Corsair. I know they're both good brands, but Corsair seems to be recommended more. So, I will put to the boards for the tie breaker. 1000W Antec or 750W Corsair?

If you can fit the CP-1000 into your case, get it over the Corsair. It's essentially an Antec Signature-quality power supply in Antec's proprietary form factor.

JG review on the 850HX. I assume the 750HX would perform very similarly, just with a lower wattage output.

JG review of the CP-1000.

Both companies have excellent CS & RMA policies/turnaround times. I'd probably go with the Corsair simply because it's slightly more efficient than the Antec.

I didn't vote yet but the CP-1000 is a monster sized unit and will NOT fit in most cases with the exception of I believe the Antec 900 and 1200 case's. That being said, the 750HX is a great PSU from everything I have read and heard of and I read alot when upgrading anything.
Why not take a look at the unit in my signature, bit on the pricey side but you can find deals if you look hard enough.

That's why I said.....if it fits his case, take the CP-1000. It's a Signature in Antec's "new" form factor at a fraction of a Signature's price, guess to stimulate sales of their cases that fit this ps.

I couldn't agree more with you. Just a shame that the CP will not fit in regular sized case's. I wanted to get the CP and even have a Wood case that I built around 7 years ago, double wide that at the time I built to fit the PCP&Cooling 840 Redundant. I figured maybe I could make the CP fit but it was a no go, so I ended up buying a used Signature here a bit ago. But again Meghan54, could not agree with you more.

I would get the Corsair over the Atec for a few reasons. Even if your case can support the CP it doesn't mean you wont at sometime want to change your case to something that won't support it.

The main reason I would choose the Corsair is the choice of caps on the Antec. They may all be of good quality but I like the all Japanese 105° rated caps on the Corsair compared to the mixed bag on the Antec.
Here are a couple quotes from the Antec review.

"Main capacitors are these 85 degree rated Ltecs. I'd like to see these improved a bit, but they're not nearly as critical as the parts over on the secondary side."

"For capacitors, Delta reached into their grab bag and pulled out a handful of various capacitors. Ltec, Nichicon, Taicon, Aishi (bless you!), and Rubycon are all represented in here. The approach must work well for them, as we saw in the scope shots."

When I look at reviews of power supplies when I am in the market for a new one the 1st thing I look at is the caps. If the are all 105° rated Japanese it is one that I will consider since I believe if they went to the expense to do that they probably didn't cut any corners elsewhere either.

Also unless you are going for more than 2 high end graphics cards there is no reason to get higher than a good 750.

If you can fit the CP-1000 into your case, get it over the Corsair. It's essentially an Antec Signature-quality power supply in Antec's proprietary form factor.

As far as electrical performance that is about right but as far as build quality not so much. You can see my quotes on the cap quality of the CP 1000 and here is the quote from the SG's review.

"Looking at the PCB from another angle, we can see the two huge Rubycon primary caps taking up a good chunk of space. The rest of the unit's capacitors are Nippon Chemi-Con and Nichicon. No expense spared there."

In a year or so I'm going to upgrade to a 9850 Radeon (I believe that's the top of the line one.) I don't plan on doing crossfire, but I'm assuming the 750 will run the top of the line Radeon card as well as the rest of my set up.
The rest of my build is:
AMD Phenom II X4 955
Asus M4A79XTD Evo
8 gigs DDR3 (Up from the 4 I have now)
A Blue Ray player (as yet to be purchased)
A DVD burner

a 650 will run that. maybe even less.

Yes the HX750 will have no problem with your system even with a 5970 (dual chip card) or the 5870 the top single gpu card.

Here is a shot I took from Xbit labs that shows the total power draw of the system with both a single and X-Fire 5870's (the X-Fire 5870 will draw quite a bit more than a 5970 since it is two 5850's on one card). You also would never get close to the figures shown during normal gaming since Furmark with load a GPU more than any game and linpack does the same with the CPU. Also those figures are shown as the draw from the wall and you can figure the actual draw on the PS to be in the area of 85% of that. You will have plenty of head room left.

Radeon 9850 was top of the line about 6 years ago....Do you mean the HD5970?

Yeah, that's what I meant.

I would get the HX750 as well. You don't need the 1kW so you might as well go with a more compatible PSU with better efficiency.

 

[MagickMan]

I run an HX650 with Xfire 5850s and an OCed Q9550 (4.2GHz) and it does it effortlessly. The HX750 is an even beefier PSU built on a better platform.

 

[bigboxes]

The Antec PSU will fit in the P183 as well, but I'd vote for a Seasonic PSU if not tied to the choices made. To be fair, I don't see how you can go wrong with any of the mentioned power supplies.

Dear Kekewy,

why going for the CP1000 and compare it? I don't know your exact criteria but you can go easily with an Antec TruePower New 750W which is just 99$ at Newegg for example. With that unit you can't do anything wrong, you have nice voltage stability, good efficiency, cable management and silence... the best price/performance ratio out there right now. You can go even lower with the wattage and save another 10-20$.

My criteria isn't that extensive. I want modular so I don't have extra cables to mess with. My current Enermax is four or five years old so I'd like a reliable one that should last at least that long. And I'd like enough wattage that I have play room for future upgrades. I'm looking to add a blu-ray player to my current system, which I know doesn't add much to the wattage, but I'm also planning on upgrading to a Radeon HD5970 in the future or possibly playing with crossfire. I'd like to have both those options open without turning around and buying a new PSU.

Oh, and if I could find all that in gray PSU, I'd buy the thing on the spot.
